The Frequency of Meal-Replacement Products Drinking and All-Cause, CVD, and Cancer Mortality.

Our study aimed to assess the associations between meal-replacement (MR) drinking and risks of all-cause, cardiovascular and cerebrovascular disease (CVD), and cancer mortality. The study was based on 6770 adults aged 20 years or older from the National Health and Nutrition Examination (NHANES) 2003-2006 with linked mortality data from the National Death Index for linked mortality records (until 31 December 2019). Respondents were categorized into four groups according to the frequency of MR drinking: ≤1 time per month (seldom), 2-3 times per month (monthly), 1-6 times per week (weekly), and ≥1 time per day (daily). The adjusted hazard ratios (aHRs) of MR drinking with all-cause, CVD, and cancer mortality were estimated by Cox proportional hazards regression models. Likelihood ratio tests were used to find potential interactions of MR drinking with age, sex, and BMI. During a median follow-up of 14.4 years, a total of 1668 death events were recorded among the study population. Compared to respondents who seldom drank MR, daily and weekly drinkers had greater risks of all-cause mortality (aHRs and 95% confidence intervals [CI]: 1.52 [1.17-1.97] for daily; 1.54 [1.24-1.91] for weekly). Stratified analyses indicated that the effects of MR on all-cause mortality were different between females and males and were more substantial among females (P for interaction: 0.003; daily female drinkers vs. daily male drinkers: 2.01 [1.40-2.90] vs. 1.24 [0.85-1.81]; weekly female drinkers vs. weekly male drinkers: 1.68 [1.26-2.24] vs. 1.36 [0.97-1.91]). Daily and weekly MR drinking might increase the risk of all-cause mortality.

Retrospective review of seven patients with obesity simultaneously treated with a combination of a glucagon-like peptide-1 receptor agonist and a meal replacement product

BackgroundThe use of meal replacement products (MRPs) to obtain a caloric deficit while maintaining micro- and macronutrient requirements, has a long tradition in obesity medicine. Limitations include low compliance, variability in efficacy, adverse events (related to acute changes in nutrient intake), and risk of weight regain when discontinued, and their popularity has declined after the emergence of potent GLP-1 receptor analogues (GLP1-RAs). However, GLP-1RAs have limitations, including dose-dependent risk for adverse events (AEs), high cost, as well as weight regain when discontinued. Although concomitant use of MRPs and GLP-1RAs could address some of the limitations, there is a scarcity of data reported on this. Herein we report real world clinical experience of such combined use. MethodsThis retrospective case evaluation involved people with obesity that concomitantly used MRPs (Optifast) and a GLP-1RA and were followed at one of three weight management centers in Australia or South Africa. Parameters collected were gender, age, co-morbidities, height, weight, frequency/amount of MRPs used, dose/type of GLP-1RA used, duration of combined use, and occurrence of AEs. Written informed consent for use of data was obtained from each individual, and the data were managed in an anonymized form and summarized descriptively. ResultA total of seven (5 females) individuals (mean [min, max] age 49 [30,66] years, BMI 44.8 [30.7, 57.9] kg/m2) initiated either semaglutide (n=4) or liraglutide (n=3) concomitantly with daily MRPs (starting number of servings/day 2.7 [1,6]) for a duration of 12 [4, 25] months. Change in weight/BMI/% TBW was -32.0 (-9.6, -77.8) kg/-10.3 (-3.4, -24.5) kg/m2/-24.2 %. Five individuals experienced ≥1 GLP-1RA related AE (nausea, reflux, burping, diarrhea, constipation). One individual discontinued GLP-1RA, whereas two persons discontinued the use of MRPs. ConclusionsMRPs can be initiated concomitantly with a GLP-1 RA for weight management. This might enhance weight-loss effectiveness, with potential additional benefits that should be elucidated in further and larger studies.

A Simulation-Based Approach for Evaluating the Effectiveness of Robotic Automation Systems in HMR Product Loading.

The food industry has tried to enhance production processes in response to the increasing demand for safe, high-quality Home Meal Replacement (HMR) products. While robotic automation systems are recognized for their potential to improve efficiency, their high costs and risks make them less accessible to small and medium-sized enterprises (SMEs). This study presents a simulation-based approach to evaluating the feasibility and impact of robotic automation on HMR production, focusing on two distinct production cases. By modeling large-scale and order-based production cases using simulation software, the study identified key bottlenecks, worker utilization, and throughput improvements. It demonstrated that robotic automation increased throughput by 31.2% in large-scale production (Case A) and 12.0% in order-based production (Case B). The actual implementation showed results that closely matched the simulation, validating the approach. Moreover, the study confirmed that a single worker could operate the robotic system effectively, highlighting the practicality of robotics for SMEs. This research provides critical insights into integrating robotics to enhance productivity, reduce labor dependency, and facilitate digital transformation in food manufacturing.

Efficacy of Meal Replacement Products on Weight and Glycolipid Metabolism Management: A 90-Day Randomized Controlled Trial in Adults with Obesity

Background: The global obesity issue is growing increasingly serious, impacting personal health, economic development, and the sustainability of medical systems. There is an urgent need for effective weight loss strategies that can be widely implemented. This study conducted a 90-day randomized controlled trial to assess the impact of meal replacement products on weight management and glycolipid metabolism in adults with obesity. Methods: Adults with obesity meeting the inclusion and exclusion criteria were divided into three groups: the meal replacement group (n = 19), the diet control group (n = 19), and the normal diet group (n = 22). The meal replacement group used specially formulated meal replacement products for dinner, and the diet control group reduced the intake of staple food at lunch, both controlling daily energy intake between 1200 kcal and 1300 kcal, while the normal diet group maintained their regular dietary habits. Relevant indicators were measured at baseline and after 45 and 90 days of intervention. Results: The results showed that both the meal replacement group and the diet control group experienced significant decreases in weight, BMI, and body fat percentage, with the meal replacement group showing a more pronounced weight loss effect. The weight loss of the meal replacement group at 45 and 90 days was 4.44 ± 1.84 kg and 7.38 ± 3.24 kg, the diet control group was 2.62 ± 2.28 kg and 4.08 ± 2.94 kg, and the normal diet group was 0.66 ± 1.73 kg and 0.97 ± 2.02 kg. The decrease in BMI at 45 and 90 days for the meal replacement group was 1.08 ± 0.78 kg/m2 and 2.17 ± 1.57 kg/m2, for the diet control group was 0.82 ± 0.80 kg/m2 and 1.39 ± 1.16 kg/m2, and for the normal diet group was 0.19 ± 0.71 kg/m2 and 0.21 ± 0.96 kg/m2. The decrease in body fat percentage at 45 and 90 days for the meal replacement group was 1.76 ± 0.68% and 3.67 ± 2.62%, for the diet control group was 1.02 ± 1.11% and 1.52 ± 1.79%, and for the normal diet group was 0.81 ± 1.09% and 0.53 ± 0.93%. In addition, the decrease in BMI and body fat percentage in the meal replacement group was also significantly higher than in the other two groups. In terms of metabolic indicators, there were no significant differences in the changes of blood pressure, blood lipids, blood sugar, and ALT levels among the three groups during the intervention period. Conclusions: In summary, the results indicate that meal replacement products can significantly reduce weight and body fat percentage without affecting metabolic health.

An internet-based platform with a low-calorie dietary intervention improves cardiometabolic risk factors in overweight and obese people in China: Half-year follow-up results of a randomized controlled trial.

To explore the effectiveness of the Metawell programme on cardiometabolic risk factors in China, which combines meal replacement biscuits, a wireless scale, and a mobile phone application. In this two-arm, parallel-design randomized study, 220 participants were randomly assigned to an intervention (n = 110) and a control (n = 110) group. Participants in the intervention group were instructed to use meal replacement products and scales for weight loss and monitoring, whereas participants in the control group received printed materials containing a sample diet and face-to-face weight loss education at enrolment. The trial lasted 6 months, including a weight loss period in Months 1-3 and a weight maintenance period in Months 3-6. Generalized estimating equations were used to compare differences between the two groups. The median (interquartile range) ages of the intervention and control groups were 32.00 (28.00, 39.00) years and 33.00 (28.25, 41.00) years, with body mass indices of 28.20 (26.30, 30.95) kg/m2 and 27.70 (26.02, 29.70) kg/m2, respectively. Participants in the intervention group experienced significantly greater decreases in waist circumference, hip circumference, triglycerides, total cholesterol: high-density lipoprotein cholesterol ratio, fasting blood glucose, fasting insulin, and homeostatic model assessment of insulin resistance index compared to the control group (p < 0.01). Among participants who did not regain weight during the maintenance period after weight loss, the reductions in systolic and diastolic blood pressure were significantly greater in the intervention group than in the control group (p < 0.05). The Metawell programme of caloric restriction and remote monitoring can be adapted to overweight and obese people in China to reduce their cardiometabolic risk factors. Furthermore, there was a better improvement in blood pressure in participants who maintained the effects of weight loss.

Comparison of the Nutritional Adequacy of Current Food-Based Very Low Energy Diets: A Review and Nutritional Analysis.

Very low energy diets (VLEDs) contain <800 kcal/day and typically comprise formulated meal replacement products with adequate protein and micronutrients. Food-based VLEDs are an alternative approach, but it is uncertain whether they can provide adequate nutrition within an 800 kcal/day restriction. This analysis aimed to assess the nutritional adequacy of food-based VLEDs compared with formula VLEDs. A systematized literature review was conducted to identify balanced food-based VLEDs by searching five scientific databases from inception to 23 March 2023 and online sources between 1 and 7 May 2023. Ultimately, nine diets were analyzed for nutritional content and compared with Codex Alimentarius standards for formula foods, and Australian estimated average requirement and adequate intake (AI) for adults 19-50 years. Optifast® was used as a comparator. None of the VLEDs met all nutritional benchmarks. Three food-based diets had nutrient profiles similar to formula VLEDs, with one being adequate for all nutrients except thiamine, magnesium and zinc in men and iron in women. All VLEDs, including Optifast®, did not meet AI for dietary fiber, except one. In general, food-based VLEDs offered more fiber than Optifast®. In conclusion, food-based VLEDs were inadequate in certain micronutrients but offered more dietary fiber than formula VLEDs. These nutritional deficits do not preclude food-based VLEDs from being recommended, provided they are addressed.

Formula diets for weight loss - chances and challenges

Formula diets, through the use of industrially manufactured meal replacement products, lead to effective and rapid weight reduction and improvement in obesity-associated comorbidities. The specific composition of these meal replacement products simplifies the adherence to calorie goals and ensures the supply of essential nutrients during significant energy restriction. Despite numerous potential applications, evidence from randomized controlled studies, and simplicity in practical implementation, challenges persist. Monotony and social restrictions complicate adherence and acceptance. The use of formula diets for sustainable weight loss requires integration into a multimodal treatment approach with the goal of long-term changes in eating and activity behaviour. This includes accompanying nutritional counselling, promotion of physical activity, evaluation of adjuvant pharmacological or interventional therapies, as well as psychological support. The development of new incretin-based anti-obesity medications has opened another application field for formula products. There is optimization potential in expanding the product range and combining it with digital applications to enhance acceptance and reach a larger patient group.

Long-Term Outcomes of Recipients of Liver Transplants from Living Donors Treated with a Very Low-Calorie Diet.

The increasing prevalence of steatotic liver disease (SLD) in potential living donors is concerning, as it limits donor's availability amid rising demand. OPTIFAST very low-calorie diet (VLCD), a meal replacement product, effectively reduces weight and hepatic steatosis before transplantation. However, data on the outcomes of recipients of VLCD-treated donors are lacking. We conducted a single-center, retrospective study on 199 living donor liver transplant recipients at Toronto General Hospital, Canada, between January 2015 and January 2020. We compared the 1-year posttransplant outcomes between recipients who received organs from donors treated with VLCD (N = 34) for either weight loss or steatosis reduction, with those who did not require treatment (N = 165). Our analysis revealed no statistically significant differences in the rates of postoperative complications (23% vs 32.4%, p=0.3) or intensive care unit stays (70.9% vs 70.6%, p=1) between recipients of non-VLCD and VLCD grafts. Following adjusted multivariate logistic regression, receipt of VLCD grafts was not associated with increased hospital length of stay. In addition, one-year mortality did not differ between the two groups (4.2% non-VLCD recipients vs 2.9% VLCD recipients, p=0.6). OPTIFAST VLCD treatment for liver donors demonstrates positive and safe outcomes in recipients, expanding the pool of potential living donors for increased organ availability.

Acceptability, Adherence, Safety and Experiences of Low Energy Diets in People With Obesity and Chronic Kidney Disease: A Mixed Methods Study

Obesity is a modifiable risk factor for chronic kidney disease (CKD) progression. Low energy diets (LEDs) have not been adequately studied in people with CKD. This study aimed to explore acceptability, adherence, safety, and experiences of two LED prescriptions in adults living with obesity and CKD. In a mixed-methods study, obese adults with CKD were prescribed two LEDs (∼800 to 1000kcal/day each), in a randomised order for 2weeks each. One diet consisted of four meal replacement products daily (Optifast®, Nestlé Health Science) and the other two pre-prepared frozen meals (Lite n' Easy®, Mitchell's Quality Foods). Participants received weekly dietitian support, completed daily adherence checklists (converted to % of provided meals/replacements consumed) and participated in post-intervention semi-structured interviews to capture their experience. Nine participants were included (mean age 46.5±14.3years, estimated glomerular filtration rate 64±26mL/min/1.73m2, 4/9 male). Mean self-reported adherence was 88±11% and mean 4-week weight change was -7.3±5.6kg. Two participants withdrew at week two. Most frequently reported side effects were hunger and headaches. Adverse events of interest included one episode each of hyperkalaemia and hypoglycaemia. No serious adverse events occurred. Four overarching themes of patient experiences were identified: strategies used to adapt, disruption to the norm, individual preferences, and influences on acceptability. LEDs were found to be acceptable and safe with high self-reported adherence rates. Future LED trials should include specialist diabetes management, close monitoring for hyperkalaemia and adequate support to assist with managing side effects and dietary and social adjustments.

MEAL REPLACEMENT AS A PART OF OBESITY TREATMENT: A NARRATIVE REVIEW

Obesity is thought to be a complicated, multifaceted chronic disease that results from the combination of environmental and genotypic variables. Implementing a wide strategy for obesity prevention and management is required given the variety and complexity of factors impacting obesity. Most healthcare practitioners use dietary therapies such calorie-restricted diets, Mediterranean diets, DASH diets, and intermittent fasting to encourage weight loss. Meal replacement products (MRPs) are used as part of a calorie restricted diet which helps to control our food choices and leads to calorie reduction. This article reviews the usage of MRP as a weight loss therapy and summarizes the literature about their effectiveness to reduce weight in patients with obesity. From the literature search, it can be concluded that MRPs contain a precise amount of macronutrients, micronutrients, and fiber to provide a nutritionally balanced meal. MRPs have been extensively studied as a weight loss therapy, and several scientific studies have confirmed their efficacy. The main ways that MRPs aid in weight loss are by reducing appetite and improving diet adherence, which makes it easier for individuals to stick to their diet plan and achieve their weight loss goals. Overall, MRPs should be considered as a viable treatment option for patients who are motivated to lose weight, as they offer a simple, convenient, and effective way to reduce calorie intake, improve diet adherence, and achieve sustainable weight loss. However, it is important to note that MRPs should be used as part of a comprehensive weight loss plan that includes regular physical activity and behavior modification strategies for long-term success.

Abstract P606: Effectiveness of Randomized Dietary Interventions for the Primary Prevention of Incident Cardiovascular Disease and Type 2 Diabetes

Objective: Randomized controlled trials (RCTs) provide opportunities to estimate the causal effects of interventions on disease risk; however, large-scale, long-term RCTs of diet for the prevention of major chronic disease endpoints are sparse. We sought to summarize RCTs comparing the effectiveness of dietary interventions for the primary prevention of clinical cardiovascular disease (CVD) events and type 2 diabetes (T2D) in adults. Methods: We conducted a systematic review and meta-analysis (PROSPERO #CRD42021283728) of RCTs exclusively with dietary interventions with outcomes of incident primary CVD events and/or T2D among adults. We searched MEDLINE and other databases and references. Eligible interventions included those providing instruction, education, and/or provisions to modify intakes of nutrients, foods, or overall dietary patterns. We excluded meal replacement products, dietary supplements, interventions with concomitant comprehensive lifestyle programs, exercise regimens, etc., trials in secondary prevention populations, and trials assessing risk factor or biomarker changes only, rather than clinical events. Two investigators performed screening and data extraction in parallel. We conducted a random effects meta-analysis to estimate the pooled effectiveness of dietary interventions compared with usual diet or low-fat control groups for CVD and T2D outcomes, separately. Results: Among the 5365 citations generated in our searches, we identified 4 eligible RCTs, representing 56,721 participants with mean ages ranging from 44.7 to 67.9 years. Mean intervention duration was 2.3 to 8.1 years, resulting in 3,151 CVD events and 3,603 T2D cases. Compared with the control diets, the various healthy dietary patterns were related to a combined 7% (relative risk [RR] = 0.93, confidence interval [CI] = 0.87-1.00) lower CVD risk and 8% (RR = 0.92, CI = 0.86-0.98) lower T2D risk. Conclusion: Despite major morbidity and mortality from CVD and T2D, there have been few large, population-based, long-term RCTs assessing the exclusive effectiveness of dietary modification for the primary prevention of clinical CVD events or T2D. Results, however, indicate that various healthy diets may be modestly effective for primary prevention.

Postmenopausal women's experiences of weight maintenance following a very low energy diet.

Very low energy diets (VLEDs) effectively induce substantial weight loss in people with obesity, yet they are rarely used as a first line treatment. There is a belief that such diets do not teach the lifestyle behavior changes needed for long-term weight maintenance. However, little is known about the lived experiences of people who have lost weight on a VLED in the long term. This study aimed to explore the behaviors and experiences of postmenopausal women who had followed a 4-month VLED (using total meal replacement products [MRPs]), followed by a food-based, moderately energy-restricted diet for an additional 8months, as part of the TEMPO Diet Trial. Qualitative in-depth semi-structured interviews were conducted with 15 participants at 12 or 24months (i.e., at 8 or 20months post diet completion). Transcribed interviews were analyzed thematically using an inductive approach. Undertaking a VLED was reported by participants to confer advantages in weight maintenance that previous weight loss attempts had not been able to do for them. Firstly, the rapid and significant weight loss, in conjunction with ease of use, was motivational and helped instill confidence in the participants. Secondly, the cessation of a normal diet during the VLED was reported by participants to break weight gain-inducing habits, allowing them to abandon unhelpful habits and to introduce in their place more appropriate attitudes toward weight maintenance. Lastly, the new identity, helpful habits and increased self-efficacy around weight loss supported participants during weight maintenance. Additionally, participants reported that ongoing occasional use of MRPs provided a useful and easy new strategy for countering weight regain and supporting their weight maintenance regimen. Among the participants in this qualitative study, most of whom had maintained a loss of over 10% of their baseline body weight at the time of interview, using a VLED in the context of a clinical weight loss trial conferred confidence, motivation and skills for weight maintenance. These findings indicate that VLEDs with clinical support could be successfully leveraged to set up behaviors that will support weight maintenance in the long term.

Ten-dimensional hyphenation including simulated static gastro-intestinal digestion on the adsorbent surface, planar assays, and bioactivity evaluation for meal replacement products.

Meal replacement products are normally consumed in weight-loss interventions and the treatment of obesity and diabetes. Changing lifestyles and eating habits made meal replacement products in the forms of shakes and bars a good alternative as To-go-meals, promoted as balanced in its composition and thus healthier compared to other ready-to-eat meals. This study aimed to evaluate the bioactivity of six differently flavoured powdered meal replacement products. Their analysis was made by a ten-dimensional hyphenation composed of digestion on the adsorbent surface, followed by normal-phase high-performance thin-layer chromatographic separation, multi-imaging, and planar assay application (effect-directed analysis), and then heart-cut elution/transfer of bioactive compound zones to reversed-phase high-performance liquid chromatography, diode array detection, and high-resolution tandem mass spectrometry. The on-surface digestion of saccharides, fats, and proteins through intestinal enzymatic activity revealed new breakdown products. These exhibited bioactivity in their different effect-profiles obtained by the Gram-negative Aliivibrio fischeri bioassay as well as α-/β-glucosidase and acetyl-/butyrylcholinesterease inhibition assays. The main bioactive compounds arising through simulated static pancreatic digestion were saturated and unsaturated free fatty acids. The synthetic sweetener sucralose was not influenced by simulated static intestinal digestion, but showed antimicrobial activity. In the prepared drinking meals with coffee and choco flavour, the acetylcholinesterase-inhibiting methylxanthines caffeine and theobromine were identified as bioactive compounds. Some other bioactive constituents could not be assigned to specific molecules and require further analyses. Although the studied meal replacement products showed health-beneficial properties through antimicrobial properties or inhibition of enzymes involved in the expression of the civilisation diseases, such as diabetes and Alzheimer's disease, plant foods, herbs and spices have been shown to be even richer and more versatile in bioactive compounds.

증기 자가방출 스마트 전자레인지 포장재 적용을 위한 복합필름 특성연구

The demands for Home Meal Replacement (HMR) products are continuously increasing owing to the convenience of instant food and online food delivery. Ready-to-heat (RTH) products have received massive attention in the HMR industry because these products can be easily warmed using a microwave oven. However, the conventional microwave packaging should be opened before microwave heating to prevent bursting or food loss owing to the steam-pressure build-up inside the package. Open packaging might lead to non-uniform food heating and cross-contamination. Therefore, packaging materials that are able to release steam without opening are of interest to the HMR industry. In this study, polylactic acid(PLA)/polyethylene glycol(PEG)/nanoclay composite films were manufactured using an extrusion method as packaging materials with a smart steam-releasing function. The introduction of PEG to the PLA imparted a steam selfreleasing feature to the composite films owing to the morphology change of composite films during microwave heating. Further, PEG increased the ductility of PLA, which in turn prevented bursting caused due to the steam-pressure build-up. The uniform dispersion of nanoclay obtained by a twin-screw extrusion led to stronger mechanical properties. Therefore, the smart composite films developed here can be applied as microwave packaging materials with a self-releasing function.

The effects of 9 months of formulated whole-egg or milk powder food products as meal or snack replacements on executive function in preadolescents: A randomized, placebo-controlled trial

Elevated brain choline is associated with better executive functions in preadolescents. Manipulating dietary choline prospectively in preadolescents using egg supplementation could improve executive functions via effects on brain cellular and neurotransmitter functions. We tested the 9-month impacts of egg supplementation on executive functions. It was hypothesized that preadolescents who consumed meal or snack replacement products containing powder made from whole eggs would have the largest improvements in executive functions after 9 months compared to those consuming similar products with either added milk powder or gelatin as a placebo. A randomized, parallel-group, double-blinded, placebo-controlled trial design was used. The executive functions of 122 preadolescents (58 females) aged 9-13 were analyzed before and after the 9-month intervention. The primary outcomes were 3 NIH Toolbox-Cognitive Battery measures of executive function: mental flexibility, working memory, and selective attention and inhibitory control. Participants were randomized to consume food products with either: 1) whole egg powder; 2) milk powder; or 3) gelatin as a placebo, all matched on macronutrient content and used as replacements for commonly consumed foods (i.e., waffles, pancakes, macaroni and cheese, ice cream, and brownies). Hypothesis testing used mixed-effects models that included physical activity and sleep scores as covariates. A statistically significant group × time interaction for selective attention and inhibitory control was found (P=0.049) for the milk group. This interaction resulted from no change for the placebo group and an improvement in selective attention and inhibitory control performance for the milk group by a T-score of 5.8; the effect size (d) was 0.44 SD units. Other comparisons were statistically insignificant. Consumption of foods with added milk powder as a replacement for snacks or meals for 9 months improves selective attention and inhibitory control in preadolescents. Replacement of foods with added whole egg powder does not impact 9-month changes in preadolescent executive functions. This trial was registered at clinicaltrials.gov as NCT03739424.

Abstract 12441: Association Between Habitual Consumption of Meal Replacement Products And Cardiac Mortality Risk in US Adults: A Prospective Study

Introduction : Little is known about the long-term association between Habitual Consumption of Meal Replacement Products and the risk of cardiac mortality. Methods: Analyses were performed using data from NHANES 2003 to 2006 and linked mortality data, consisting of 5292 participants aged 20 to 84 years old. The frequency of MR consumption was categorized into 3 groups according to the food frequency questionnaire: seldom, often and almost every day. Linked cardiac mortality records from the National Death Index were documented till Dec 31, 2019. Cox regression models were fitted controlled for demographic characteristics, social-economic factors, disease histories, and lifestyle factors. Results: At baseline, the overall percentage of American adults consuming MR products often and almost every day were 10.39% and 3.34%. During a median follow-up of 10.75 years, 98 death events due to heart diseases were recorded. Compared to respondents who seldom consumed MR products, respondents consuming MR products almost every day were associated with higher cardiac mortality risk (Adjusted HR and 95% confidence intervals: 2.51, 1.07 to 5.91, P value=0.035). Conclusion: Habitual consumption of MR products might be associated with higher cardiac mortality risk.

다양한 쌀 기반 가정간편식 제품들의 전자레인지 조리 전후의 품질 특성 평가

The physicochemical characteristics of five types of rice-based home meal replacement (HMR) products (instant rice, doshirak, kimbab, frozen fried rice, and freeze-dried rice) were measured before and after microwave cooking, and principal component analysis (PCA) was performed. HMR products contained grains from 8.42 to 8.72 mm before and after the microwave cooking. The amylose content and water absorption index (WAI) ranged from 20.10-23.15% and 0.50-2.87%, respectively. Frozen fried rice showed high amylose content but low WAI, and dry rice showed low amylose content but high WAI. There was a change in the moisture content of freeze-dried rice: moisture increased from 1.3 to 60.3% after cooking. The rehydration rate of freeze-dried rice was about twice higher than that of other HMR products, while instant rice showed a low rehydration rate. The texture profile's hardness and cohesiveness respectively were 306.1 g/cm2 and 47.9% before cooking, but 209.6 g/cm2 and 66.0% after cooking. The lightness value decreased from 72.5 to 68.9 after the microwave cooking, while there was little change in the lightness value of instant rice, and that of the frozen fried rice decreased. PCA revealed that, microwave cooking apparently affected WAI and rehydration rate in the freeze-dried rice yellowness in the frozen fried rice, and stickiness and lightness in the instant rice, respectively.
