Hello Reader,

I hope you have enjoyed the last week. I shared a scheduled post last weekend because I was away in Brisbane to see my daughters and parents. 

A few of us went to The Ekka. It was so good.

Recipe

Equipment

  • Pressure cooker [1]
  • Stick blender

Ingredients

  • Potatoes
  • Leek [2]
  • Beef short rib [3, 4]
  • Bouquet garni
  • Vegetable stock
  • Chillies
  • Parsley
  • Garlic

Instructions

  1. Wake up wondering what to cook on a wet winter day in Canberra. Do you wake up and immediately think of food? Sometimes I do. This morning I did not. I slept poorly, and when my eyes opened, my first thought was craving more sleep.
  2. Go grocery shopping to plan what to cook while in the meat section.
  3. Choose a couple of beef short ribs to be the meal’s centrepiece.
  4. Heat the oven to about 200 °C.
  5. Cut a couple of potatoes into large chunks.
  6. Cut the white part of a large leek from the green part and then separate the leaves under running water to wash out the dirt.
  7. Peel a few garlic cloves.
  8. Spread the ribs, potato, leek, and garlic onto a baking sheet and put it into the oven.
  9. Keep an eye on the tray and remove the tray when the food starts to change colour and caramelise.
  10. Put the chillies, garlic, leek, and potato into the pressure cooker.
  11. Add the bouquet garni and the ribs on top.
  12. Pour in some vegetable stock.
  13. Seal the lid to the pressure cooker and set the timer to one hour.
  14. Cook the contents.
  15. Remove the lid when the pressure has equalised.
  16. Lift out the ribs, the meat, and the bouquet garni.
  17. Put the meat into a bowl, and with forks, pull the meat.
  18. Process the soup with a stick blender.
  19. Place some of the meat into the centre of a soup bowl.
  20. Ladle the soup around the meat.
  21. Garnish the soup with parsley.
  22. Give thanks to the Lord.
  23. Eat with a spoon.

Thoughts on the meal

I could have made this soup more decadent with cream and perhaps some butter. However, cream and butter were unnecessary for flavour. There’s also enough fat in the beef.

I have enough soup leftover for a few more meals. I’ve aliquoted the soup into vacuum bags, and the bags are in the freezer.

Final thoughts

How do you feel about carnival food? Do you like deep-fried sausages covered in the batter? Do you like battered chicken nuggets with hot chips, bacon pieces, cheese, and spring onion?

Would you add cream and butter to potato and leek soup?

Counseling a Chinese patient on a low-sodium diet can be an arduous task for the dietitian. Special consideration of cultural beliefs, food preferences, and food practices must be incorporated into the individualized instruction. Equally important is the need for familiarity with the sodium values of frequently consumed foods and condiments indigenous to the Chinese population. To date, published sodium determinations for such items are quite limited. Representative samples of commonly used Chinese seasonings and sauces were collected. Analysis was performed by Atomic Absorption Spectroscopy. Many of the condiments often forbidden in the sodium-restricted diet contained less than 200 mg. sodium per teaspoon in all the samples tested. These included: sweet bean sauce, rinsed and unrinsed fermented black beans, hoisin sauce, satay sauce, fermented bean cake, and rinsed and unrinsed dried shrimp. These data can give the dietitian the option of calculating these often “forbidden” items into the sodium-restricted diet. Factors to be considered are the patient’s typical meal pattern, situational needs, comprehension level, degree of compliance, and other available information.

BACKGROUND: Intake of vegetables in children remains low. OBJECTIVE: To compare taste exposure (TE), nutrition education (NE) and TE+NE together on intake of an unfamiliar vegetable (mooli/daikon radish) in preschool-aged children. DESIGN: Children attending 11 preschools in England were randomly assigned by clusters to four intervention conditions using a 2×2 factorial design: TE, NE, TE+NE, and no intervention (control). PARTICIPANTS: Two hundred nineteen children aged 2 to 5 years participated from September 2016 to June 2017. INTERVENTION: The intervention period was 10 weeks preceded and followed by measurements of raw mooli intake as a snack. Preschools were randomized to receive weekly TE at snack time (n=62 children); NE (n=68) using the PhunkyFoods program; TE+NE (n=55) received both weekly taste exposures at snack and lessons from the PhunkyFoods program; and the control condition (n=34), received NE after the final follow-up measurement. MAIN OUTCOME MEASURES: Individual measured intakes of mooli at Week 1 (baseline), Week 12 (postintervention), and Week 24 and Week 36 (follow-ups). STATISTICAL ANALYSIS: Differences in intakes were analyzed by cluster. Logistic regressions were conducted to examine odds ratios for intake patterns. RESULTS: Data from 140 children with complete mooli intake assessments were analyzed. TE increased intake from 4.7+/-1.4 g to 17.0+/-2.0 g and this was maintained at both follow-ups. Children assigned to the NE conditions were more likely to eat some of the mooli than children who were not in the NE conditions (odds ratio 6.43, 95% CI 1.5 to 27.8). Combining TE and NE produced no additional benefit to intake beyond TE alone. CONCLUSIONS: Taste exposures encouraged children to eat more of the unfamiliar vegetable, whereas nutrition education encouraged children who were noneaters to try the vegetable. Both approaches were effective and can be used to produce different outcomes.

In the present study, urine samples were collected from healthy human volunteers to determine the metabolic fates of phenolic compounds and glucosinolates after a single meal of kale and daikon radish. The major glucosinolates and phenolic compounds in kale and daikon radish were measured. The urinary metabolome after feeding at different time periods was investigated. A targeted metabolite analysis method was developed based on the known metabolic pathways for glucosinolates and phenolic compounds. Using a targeted approach, a total of 18 metabolites were found in urine: 4 from phenolic compounds and 14 from glucosinolates. Among these metabolites, 4-methylsulfinyl-3-butenyl isothiocyanate, 4-methylsulfinyl-3-butenyl isothiocyanate-cysteine, and 4-methylsulfinyl-3-butenylglucosinolate-N-acetyl cysteine were reported for the first time in human urine. The combination of non-targeted and targeted metabolomic approaches can gain a full metabolite profile for human dietary intervention studies.

Fatty acid composition contributes greatly to the nutritional value of meat, and breeds/strains are important factors affecting the composition of fatty acid. Recently, few studies have focused on the fatty acid composition in breast muscle of different duck breeds. Therefore, the objective of the present study was to compare the fatty acid composition and lipid metabolism-related genes expression in breast muscle of Jianchang duck (J), Cherry Verry duck (CV) and 3 crossbred strains (BH1, BH2 and MCmale symbol x (BGF2male symbol x GF2female symbol)female symbol (MBG)). Our results showed that the breast muscle of J had the highest contents of C22:1(n-9) but the lowest ratios of -omega 6 (n-6)/-omega 3 (n-3), -mono-unsaturated fatty acid (MUFA)/-saturated fatty acid (SFA) and -polyunsaturated fatty acid (PUFA)/SFA. The PUFA/SFA ratio was higher in breast muscle of MBG than in that of BH2 and CV, and the contents of C22:1(n-9), MUFA and PUFA were higher in BH1 than in BH2 and CV. Furthermore, the mRNA levels of SCD1, FADS2, ELOVL2, and ELOVL5 were significantly higher in MBG (P < 0.05), while those of FASD1 and ACACA were significantly higher in BH1 than in BH2 and CV (P < 0.05). Principal component analysis showed that fatty acids variation exhibited extensive positive loading on principal components (PCs). Correlation analysis showed that PC1 and PC3 of BH1, as well as PC1 of MBG were correlated with the mRNA levels of ACACA and FABP3, respectively. Thus, it could be concluded that the breast muscles of MBG and BH1 have better fatty acid composition, which was closely related to the increased expression levels of SCD1, FADS2, ELOVL2, and ELOVL5 genes in MBG but FADS1 and ACACA in BH1. Moreover, these results also showed that crossbreeding could optimize the composition of fatty acid in breast muscle of ducks.

 

Chicken and speck congee with some duck

Hello Reader,

Welcome to Canberra, where this morning, when I alighted from bed at 4 am, it was –5.9 °C with an apparent temperature of –8.6 °C.

The best food for such a cold morning is my favourite food. Congee transports me back to my childhood, except at home, we called it jook.

As I was showering yesterday, I decided on jook for tea tonight. Coincidentally, Lorraine’s Friday blog post also mentioned congee, so the deal was sealed in my head. 

In the title of this post, you’ll see I’ve mentioned duck. Last weekend I cooked two duck breasts, and I still had a portion to use. There’s no way I would waste duck breast, especially since I kept the skin and fat. 😊

Ingredients

Instructions

  1. Wash the rice in tap water until the starch has been removed. Did you know that the consistency and appearance of the stools associated with cholera diarrhoea is described as rice water? (Alexakis 2017) When you look at the water as you finish washing rice, think of the ongoing cholera pandemic (seventh), which started in Indonesia in 1961 and continues today. Check out the reference for photographs of the rice water stool.
  2. Add some cold stock to the rice in a pressure cooker vessel.
  3. Slice the shallots and chillies and toss them in along with a few dried shiitake mushrooms.
  4. Mix through the duck breast pieces and lay the chicken thighs and speck on top.
  5. Splash some sesame oil over the skin of the chicken.
  6. Seal the lid of the pressure cooker and cook for 45 minutes.
  7. When the pressure inside the cooking vessels equals the pressure outside, remove the lid and carefully scoop out the chicken pieces and speck. The meat may tear off during the lifting from the pressure cooker so be careful.
  8. Place the chicken in a large bowl and the speck on a cutting board.
  9. Pull the chicken meat and skin with two forks and sucks the bones of the juices and remaining tit bits of flesh. 
  10. Roughly cut up the speck with a knife.
  11. Put the meat back into the cooking vessel and with a spoon stir the meat through the rice gruel.
  12. Slice some spring onion for garnishing.
  13. Transfer some jook to a bowl, add a splash of soy sauce, and garnish with the spring onion.
  14. I also prepared some crispy kale sprouts with my meal. Mum would often have shredded ham and iceberg lettuce too.
  15. Give thanks to the Lord.
  16. Eat with a spoon and feel good knowing this rice gruel will pass through your œsophagus into your stomach and feel like it will warm you from the inside.

Thoughts on the meal

I remain impressed with my electrically powered pressure cooker. It is more convenient than a traditional stovetop version. Last night, I had a chicken though, a small portion of pumpkin, some vegetable stock, and some chillies. Within an hour I had a delicious chicken soup.

I feel full. I think tomorrow when I weigh myself, I might be a kilogram heavier than I weighed this morning.

            The aim of this study was to investigate the effects of different curing methods on protein structure, protein and lipid oxidation, lipolysis and volatile compounds in duck breast meat. The results showed that compared to static brining and pulsed pressure salting, the vacuum tumbling curing significantly decreased the oxidation of proteins and lipids, and the surface hydrophobicity of proteins, increased α-helix structure but decreased the proportion of β-sheet, and increased actomyosin dissociation, liplysis and the free fatty acid content in meat. Meanwhile, vacuum tumbling curing decreased the amount of volatile flavor compounds, hexanal, 2,3-octanone, and off-flavor compounds 1-octen-3-ol and 1-hexanol. This study suggests that concerns on healthiness and the sensory quality of processed meat products should be paid in the selection of curing methods and vacuum tumbling curing is superior in terms of both aspects.

Obayashi, Y. and Y. Nagamura (2016). “Does monosodium glutamate really cause headache? A systematic review of human studies.” J Headache Pain 17: 54.

            Although monosodium glutamate (MSG) is classified as a causative substance of headache in the International Classification of Headache Disorders 3rd edition (ICHD-III beta), there is no literature in which causal relationship between MSG and headache was comprehensively reviewed. We performed systematic review of human studies which include the incidence of headache after an oral administration of MSG. An analysis was made by separating the human studies with MSG administration with or without food, because of the significant difference of kinetics of glutamate between those conditions (Am J Clin Nutr 37:194-200, 1983; J Nutr 130:1002S-1004S, 2000) and there are some papers which report the difference of the manifestation of symptoms after MSG ingestion with or without food (Food Chem Toxicol 31:1019-1035, 1993; J Nutr 125:2891S-2906S, 1995). Of five papers including six studies with food, none showed a significant difference in the incidence of headache except for the female group in one study. Of five papers including seven studies without food, four studies showed a significant difference. Many of the studies involved administration of MSG in solution at high concentrations (>2 %). Since the distinctive MSG is readily identified at such concentrations, these studies were thought not to be properly blinded. Because of the absence of proper blinding, and the inconsistency of the findings, we conclude that further studies are required to evaluate whether or not a causal relationship exists between MSG ingestion and headache.

Vici, G., et al. (2021). “Nutritional Properties of Rice Varieties Commonly Consumed in Italy and Applicability in Gluten Free Diet.” Foods 10(6).

            Gluten-free diets are often characterized by an inadequate intake of nutrients and are generally monotonous for the limited number of products celiac patients can use. As rice is the most used cereal by celiac consumers, studying rice varieties nutritional characteristics is of interest to manage diet quality and variety. Proteins, total carbohydrates and amylose content of six rice varieties (Ribe, Vialone Nano, Carnaroli, Arborio, Basmati, and Fragrance) were analyzed. Analyses were performed in raw products and after boiling, stewing, and microwaving. A decrease of proteins and total carbohydrates amount was observed in cooked rice. The same was reported for amylose content with boiling showing the highest loss (average retained amylose 53%). Considering amylose percentage with respect to total carbohydrates, each variety showed either an increase or a decrease depending on cooking method. The highest values were obtained with stewing above all for Basmati rice and Arborio rice. However, exceptions can be underlined as Carnaroli rice, showing the highest percentage when boiled. In this context, nutritional characteristics of cooked rice varieties appear to be of great importance to increase specific nutritional knowledge to better manage gluten-free diets.

Beef short ribs cooked in the oven

Hello Reader,

If you don’t want to read the story, feel free to jump to the recipe.

How has your week been? Winter in Canberra has started to bite. On Friday, we had a frosty –5.5 °C morning. As I drove to work, the windscreens of all the cars parked on the road where I live were covered in ice. For readers in the USA, Liberia, and Myanmar, that’s about 22 °F.

My week’s highlight was the football game on Wednesday night. It was game three in this year’s state of origin series. It was being played at the home of Queensland rugby leagueviz., Lang Park (also known as Suncorp Stadium).

Queenslander
I used this as my videoconference background at work on Thursday morning

It was a thrilling game, with three players leaving the field in the first few minutes because of head clashes. None of them returned after their head injury assessments.

In the latter part of the second half, there was also some biff (or biffo or fisticuffs). I didn’t see it because rather than watch the game on TV, I listened to it on a smart device application

While the lead changed a few times, it was a tight game, and the outcome was not certain until the very end; the Queensland Maroons were victorious, which meant we won the 2022 series two games to 1.

Beef short rib with potato, pumpkin, Brussels sprouts, and mushrooms

Recipe

Equipment

  • Skillet
  • Oven

Ingredients

Instructions

  1. The night before, remove the beef from its wrapping and dry with paper towels. Season with salt and place the ribs on a rack and keep the meat uncovered in the refrigerator overnight. This is known as dry brining.
  2. A few hours before you plan to serve dinner, dice the carrot, onion, and celery. Slice the mushrooms and halve the Brussels sprouts.
  3. Heat a skillet and sear the surfaces of the meat. There’s no point trying to do this to the surface of the rib bones.
  4. While searing the meat, add two halves of a garlic bulb with the cut surfaces down to apply maximum heat to the garlic. Add the diced carrot, celery, and onion to the hot skillet.
  5. Turn the oven on to about 150 °C.
  6. When the meat is seared, and the vegetables have taken on some colour, add some red wine and bring it to a simmer.
  7. Simmer the wine for a few minutes and allow it to reduce a little.
  8. Cut a potato in half lengthwise and a small piece of pumpkin.
  9. Place the meat into a baking tray. Next to the meat, add the garlic, potato, and pumpkin. Then add the carrot, celery, and onion.
  10. Pour the cooking juices over the ribs and add some vegetable stock.
  11. Cover the baking tray with aluminium foil. Place the baking tray into a larger one which has some water in it.
  12. Place the baking trays into the oven and cook for about three hours. The internal temperature of the beef needs to get to at least 95 °C (about 200 °F).
  13. After about three hours, remove the baking trays and the aluminium foil. Add the Brussels sprouts and mushrooms to the baking tray and return the trays to the oven for another 30 minutes.
  14. Once the Brussels sprouts and mushrooms are cooked, remove and cover the meat and vegetables.
  15. Move the ribs and vegetables to a warm spot and sieve the juices.
  16. Make a roux with some butter and flour, and then thicken the cooking liquor to make a sauce.
  17. Pull off some of the meat from the bone and put the rest into vacuum bags for meals during the week.
  18. Place one half of a potato and the pumpkin onto a dinner plate. Add the Brussels sprouts and mushrooms and finally the meat.
  19. Pour the sauce over the meat.
  20. Give thanks to the Lord.
  21. Eat with a knife and fork.

Thoughts about the meal

This is the first time I’ve cooked beef short ribs in the oven. I’ve cooked them before in a slow cooker and in a pressure cooker.

The meat was tender yet firm. It was firmer than the meat cooked in a pressure cooker or in a slow cooker.

Overall, the meat had tremendous flavour and mouthfeel.

Final thoughts

  1. Have you cooked beef short ribs in an oven before?
  2. What is your preferred way to cook beef ribs?
  3. Do you have any ideas on how I should enjoy the leftover rib meat?
  4. How do you feel about the risk of colorectal carcinoma and mammal meat? (Joshi, Kim et al. 2015)

I hope you have a wonderful week. Next week, I’m thinking of roasting a duck. (Baker and Darfler 1981, Chen, Zhao et al. 2020)

            Chicken broilers, chicken roasters, turkeys, and ducks were split; then one half was stored frozen; the other half was iced. Two days later, both halves were baked and then evaluated using the triangle test. Shear values and expressible fluid values were also determined. The taste panel could not significantly distinguish between fresh and frozen thawed paired halves of roast poultry. Objective testing by shearing and expressible moisture losses also failed to show a significant difference. However, of the judges who could distinguish between the fresh and the frozen thawed samples, the greater percentage preferred the fresh samples.

 

Chen, X., et al. (2020). “Effect of modified atmosphere packaging on shelf life and bacterial community of roast duck meat.” Food Res Int 137: 109645.

            The purpose of this work was to assess the effect of different packaging methods on the shelf life and bacterial communities of roast duck meat. Samples were packaged under the following five conditions: overwrapped packaging (OWP), 100% N2 (100% N2-MAP), 30% CO2/70% N2 (30% CO2-MAP), 50% CO2/50% N2 (50% CO2-MAP), and 0.4% CO/30% CO2/69.6% N2 (CO-MAP). Physicochemical and microbiological parameters were monitored during 14 days of chilled storage (0-4 degrees C). Results showed that MAP samples obtained higher and more stable redness, better sensory scores, and lower lipid oxidation, compared with OWP, in which CO-MAP samples had the lowest TBARS values (0.13-0.22 MDA/kg) during storage. Moreover, 30% CO2-MAP, 50% CO2-MAP, and CO-MAP effectively retarded the onset of bacterial spoilage and extended shelf life by 7 days compared with 100% N2-MAP and OWP treatments. Additionally, bacterial succession was significantly affected by the gas composition used in the packages, especially the dominant biota at the end of storage, which played an important role in the spoilage of roast duck meat under specific packaging. On day 14, Pseudoalteromonas spp., Lactobacillus spp., and Pseudomonas spp. became the most predominate genera in OWP, 100% N2-MAP, and 50% CO2-MAP, respectively. Notably, Vibrio spp. was dominant in both 30% CO2-MAP and CO-MAP, indicating 0.4% CO did not exert a further inhibitory effect on this genus. Additionally, the growth inhibition of Pseudoalteromonas spp., Lactobacillus spp., and Leuconostoc spp. by high CO2 concentration might be the reason for MAP (CO2/N2) samples having lower levels of TVC. Globally, these results indicate that 30% CO2-MAP, 50% CO2-MAP, and CO-MAP are promising packaging methods to improve roast duck meat quality and achieve shelf life extension.

            Diets high in red meat and processed meats are established colorectal cancer (CRC) risk factors. However, it is still not well understood what explains this association. We conducted comprehensive analyses of CRC risk and red meat and poultry intakes, taking into account cooking methods, level of doneness, estimated intakes of heterocyclic amines (HCAs) that accumulate during meat cooking, tumor location, and tumor mismatch repair proficiency (MMR) status. We analyzed food frequency and portion size data including a meat cooking module for 3364 CRC cases, 1806 unaffected siblings, 136 unaffected spouses, and 1620 unaffected population-based controls, recruited into the CRC Family Registry. Odds ratios (OR) and 95% confidence intervals (CI) for nutrient density variables were estimated using generalized estimating equations. We found no evidence of an association between total nonprocessed red meat or total processed meat and CRC risk. Our main finding was a positive association with CRC for pan-fried beefsteak (P(trend) < 0.001), which was stronger among MMR deficient cases (heterogeneity P = 0.059). Other worth noting associations, of borderline statistical significance after multiple testing correction, were a positive association between diets high in oven-broiled short ribs or spareribs and CRC risk (P(trend) = 0.002), which was also stronger among MMR-deficient cases, and an inverse association with grilled hamburgers (P(trend) = 0.002). Our results support the role of specific meat types and cooking practices as possible sources of human carcinogens relevant for CRC risk.

The characteristics of meat studied were the sensory, rheological, and color of the longissimus muscle (LM) and the rheological traits of four other muscles: complexus, infraspinatus, rhomboideus, and serratus ventralis. The main results showed that WLP rearing managements did not significantly impact the tenderness (sensory or rheological analyses) of the rib muscles. The LM had high (p ≤ 0.05) typical flavor and was appreciated when heifers received a WLP rearing management characterized by a short pasture duration during the heifers’ whole life (WLP-E). The heifers’ management characterized by a long pasture duration during their life (WLP-A) or by a diet composed mainly of hay during the growth and fattening periods (WLP-F), had lower typical flavor and were less appreciated than those with WLP-E management. Moreover, the LM color was redder for heifers of WLP-E than those of the WLP-A and WLP-F groups. This study confirmed that it is possible to obtain similar meat qualities with different rearing managements.

Pressure cooker beef cheeks and vegetable soup

Hello Reader,

I hope you’ve had a good week. For me, two loved ones experienced serious health problems. I expect one will make a full recovery and the other will hopefully see this experience as an opportunity for change.

I’m reminded of my own mortality when people I love are suddenly and unexpectedly affected by a serious health problem.

I was going to call this rubbish bin soup because the vegetables were all old and were about ready to throw away. They were limp and I had to look hard for mould. Given I was using a pressure cooker, I had no fears for the safety of the food. A pressure cooker is an autoclave by another name. So, I saved these vegetables from the rubbish bin and made soup! 😊

Instructions

  1. Buy a pair of beef cheeks from the supermarket or butcher. [I bought these beef cheeks from the supermarket.]
  2. Remove the meat from the plastic wrap and put the cheeks into a vacuum bag along with some barbecue sauce and Worcestershire sauce. Vacuum seal the bag and put the marinading meat into the refrigerator for about a day. The meat should absorb the spicy vinegary flavours of the sauces and get a hit of umami from the anchovies in the English version of fish sauce.
  3. Dice the vegetables into cubes about 1 cm3.
  4. Put the vegetables into a large bowl and pour in a little rice bran oil plus some salt. Massage the oil and salt onto the vegetables.
  5. Put the vegetables onto a baking sheet and put into a hot oven until they start to caramelise on the cut edges.
  6. When the vegetables were ready from the oven, put the beef cheeks and vegetables into the pressure cooker and put on the lid. For at pressure for one hour. This should ensure the meat would be tender and easy to tease apart.
  7. Once the hour has passed, wait for the pressure in the vessel to equal the pressure outside the vessel and remove the lid.
  8. Lift the meat from the vessel. Be careful, the meat will fall apart under the force of its own weight. Scoop a flat sieve under the meat and lift it so the cooking liquor drains off back into the cooking vessel and transfer the meat to a large bowl.
  9. Pour the contents of the pressure cooker vessel into a large stainless-steel saucepan.
  10. Tease apart the beef muscle and connective tissue fibres and lay them out on a baking sheet. Smear some barbecue sauce over the meat and put it into a gentle oven to partially dehydrate. The excess liquid will evaporate leaving sticky meat.
  11. Turn on the hob for the saucepan and bring the broth to a gentle simmer so it can reduce a little.
  12. Once you achieve a consistency you think is right, use a stick blender to process the broth into a soup.
  13. Divide the soup into aliquots for freezing and keep one portion in the saucepan.
  14. Add a dollop of sour cream to thicken the soup and pour it into a bowl.
  15. Add some of the sticky pulled beef.
  16. Give thanks to the Lord.
  17. Eat with a spoon.

Thoughts of the meal

Not a bad meal. A bit of an odd concept I think others may say. Not to worry, I’m the one eating it.

I’ll have plenty of meat for this week and a few bowls of soup to keep for the freezer.

Final thoughts

  • How do you feel when loved ones take ill?
  • Have you ever made a rubbish bin meal?
  • Do you like meaty soups?

BACKGROUND: Sterilization of healthcare instruments in an expeditionary environment presents a myriad of challenges including portability, cost, and sufficient electrical power. Using pressure cookers to sterilize instruments presents a low-cost option for sterilization in prehospital settings. This project’s objective was to determine if sterility can be achieved using a commercially available pressure cooker. METHODS: Presto(R) 4-quart stainless steel pressure cookers were heated using Cuisinart(R) CB-30 cast-iron single burners. One 3M Attest 1292 Rapid Readout Biological Indicator and one 3M Comply SteriGage integrator strip were sealed in a Henry Schein(R) Sterilization Pouch and placed in a pressure cooker and brought to a pressure of 103.4kPa. Sterility was verified after 20 minutes at pressure. The Attest vials were incubated in a 3M Attest 290 Auto-Reader for 3 hours with a control vial. RESULTS: Sterility using the pressure cooker was achieved in all tested bags, integrator strips, and Attest vials (n = 128). The mean time to achieve the necessary 103.4kPa was 379 seconds (standard deviation (SD) = 77). Neither the ambient temperature nor humidity were found to affect the pressure cooker’s time to achieve adequate pressure, nor the achieved depth on the integrator strip (all p > .05). CONCLUSION: This study provides evidence that sterilization is possible with offthe- shelf pressure cookers. Though lacking US Food and Drug Administration (FDA) approval, the use of this commercially available pressure cooker may provide a method of sterilization requiring minimal resources from providers working in expeditionary environments.
