  • Generic HACCP models for bakery products may help HACCP implementation at the wholesale bakery production lines easier. When baking, the internal temperature of bakery products went up to $85^{\circ}C$, which resulted in gelatinization of starch. Considering the characteristics of bakery products, general sanitation control procedures are the main target tool to keep bakery products safe. Monitoring of pathogenic microorganisms at bakery plant environment including production lines was carried out. At the wholesale bakery environment pathogenic microorganisms were detected. It gave a clue that general sanitation control procedures should be implemented for safe bakery products supply. Hazard analysis of raw materials and processing of bakery products, and determination of critical control points and critical limits at the wholesale bakeries lead to present generic model of bakery product HACCP plan. CCPs for the wholesale bakery products may be applied and modified for the implementation of HACCP plan at the wholesale bakery plant.

  • The purpose of this study was to evaluate the important changes and the trends in Korean newspaper articles related to 1) food habits and food consumption patterns 2) nutrition, health and diseases 3) food safety and policy. The method used in this study was content analysis of the articles pressed in Donga ilbo and Choseun ilbo from January 1960 to June 1996. Among the total 1814 articles, those on nutrition, health and disease were 922 (50.8%), food safety and policy were 490 (27%) and food habits and consumption patterns were 402 (22.2%). The articles related to food habits and consumption patterns dealt with four contents, food habits reformation, changes in food consumption patterns, nutritional status and food habits. The frequencies of food habits content were highest (51.1%) and especially increased in 1980's and 1990's as the concerns on health and pursuit of convenience were increased. Most of contents related to food habits were health and longevity diet (44%) and eating out (27.5%). The percentile of food habits reformation, the changes in food consumption patterns and nutritional status were 20.1%, 18.4% and 10.0%, respectively. The contents of food habits reformation were most interested in 1960's when food shortage and poverty prevailed. Nowadays, the major subjects of food habits reformation were changed to the problem of wastage and the use of our agricultural foods. The frequencies of change in food consumption patterns were gradually increased from 1960's (7 item) to June 1996 (34 items). And the most of contents related to nutritional status were focused on suffering from food shortage especially in 1960's.

  • The safety of pufferfish (Lagocephalus gloveri) liver oil and the contents of some nutritional components were examined to obtain important information on their use as high valued functional foods. Pufferfish liver oil was extracted by the hot-water method using $1\%$ NaOH solution to remove toxic compounds, and then purified using a general purifying method of fish oil. Any extraordinary clinical symptoms were not observed from all groups administrated with pufferfish liver oil throughout the test period. None of the rats died when administrated the highest concentration of 10 mL/kg of the pufferfish liver oil. Vitamin A content was 114.2 ppm, as a retinal equivalent in the oil extracted using hot-water, but the content was higher (169.3 ppm) in oil extracted using n-hexane. Vitamin D and E were not detected in ppm in oil extracted using hot-water. Vitamin D in the pufferfish liver oil extracted using n-hexane was also undetected, but vitamin E was at 32.5 ppm. Among the 18 minerals detected, the sodium content was the highest at 253.5 ppm, followed by 13.9 ppm ofpotassium, 1.5 ppm of calcium, 0.2 ppm of magnesium, and other trace minerals. The contents of EPA and DHA were $0.8\%\;and\;14.8\%$, respectively, in the pufferfish liver oil extracted using hot-water. Considering these results, there is potential that pufferfish liver oil could be used as a functional food.

  • The purpose of this study was to investigate middle school students` perceptions on foodborne illness prevention in relation to their personal hygiene practices. The survey was administered in July, 2007 at one middle school, with a total of 390 students participating. The self-completed questionnaire consisted of several questions regarding the students` awareness of foodborne illness, perceptions of foodborne illness prevention, and personal hygiene practices. T-tests were used to identify the differences in their perceptions of foodborne illness prevention based on gender and Chi square tests were used to identify the relationships between their perceptions of foodborne illness prevention and personal hygiene practices. Eight percent of the respondents experienced foodborne illness at least once a year and 33.8% of them have stopped eating certain foods due to anxiety towards foodborne illness. The students perceived school foods (26.0%) and street foods(17.9%) as the main sources of foodborne illness, and dairy products(20.0%) and fresh fish (19.7%) were considered foods having the greatest potential for causing foodborne illness. Many students were aware of Escherichia coli O157(43.1%) and Hepatitis A(23.3%), but only a few recognized Clostridium botulinum(4.1%) and Salmonella(7.9%), even though these are major foodborne illness-causing pathogens. The students considered foodborne illness prevention very important(mean = 4.33); also, the results showed that many washed their hands 3-4 times (34.1%) and 5-6 times(29.2%) per day. Hand washing frequency was significantly related to the perceived importance of personal hygiene practice as well as to education on safety and sanitation. However, the students` perception on the importance of personal hygiene practices were not significantly different based on having received safety and sanitation education. Ultimately, these results will be used to develop guidelines for effective education on safety and sanitation.

  • BACKGROUND/OBJECTIVES: Although children of ethnic minority groups are experiencing a transition from a predominance of undernutrition to overnutrition, there is little evidence of a dual-malnutrition burden. Therefore, this study examined the double burden of malnutrition among school-aged ethnic minority children living in mountainous areas and its association with their diets. SUBJECTS/METHODS: A cross-sectional study was conducted from September 2019 to March 2020 in 3 mountainous areas of Northern Vietnam among 1,556 ethnic minority school-aged children. The prevalence of under-nutrition (stunting and thinness) and over-nutrition (overweight and obesity) were measured using the WHO 2006 child growth standards (height-for-age and BMI-for-age Z-score). Nutritional practices were evaluated by the frequency of food consumption based on a 4-level scale. RESULTS: The percentage of children with stunting and thinness were 14.0% and 5.4%, respectively, while the figure for overweight/obesity was 9.4%. The factors positively associated with stunting were living in a family with more than 2 children or being Muong/other ethnicities compared to the Tay ethnicity. Children who consumed fish/shrimps/crabs or milk weekly/daily were less likely to be undernourished compared to those who never consumed these foods. By contrast, children who never consumed foods rich in vitamin A precursors and vitamin A and fruit or consumed daily snacks/junk food were more likely to be overweight/obese. CONCLUSIONS: Undernutrition remains a common issue among school-aged children and adolescents of ethnic minority groups, while over-nutrition exists simultaneously. Public health nutrition programs promoting adequate diets and positive lifestyle changes related to nutrition are essential to tackle the double burden of malnutrition among ethnic minority children.

  • The food composition database is used to evaluate the nutritional value of foods in Korea. It is used as a source for basic data in many fields, not only for the establishment of the National Food Supply Plan but also for nutritional research, to aid in the drafting of the National Food Policy, and in clinical and epidemiological research. The database is also used by institutional and commercial food services and by the food processing industry among others. In 1970, the Rural Development Administration(RDA) published the "Korean Food Composition Table" for the first time and it has since become the established authority on food composition for the entire nation. The latest published food composition table (the 6th edition, published by the National Rural Living Science Institute, KDA) covers 2,337 kinds of foods and consists of two volumes. The National Rural Living Science Institute, the Korea Food and Drug Administration, and the National Fisheries Research and Development Institute have continuously improved production of food composition data in Korea. As consumers have grown more interested in the quality and safety of foods and raw agricultural products, we can expect even further development of food composition data through improvements in quality and increases in quantity. We need to develop more comprehensive food composition data by diversifying the kinds of foods that are included, unifying analytical methods, and increasing the number of nutrients covered. Moreover, food composition data must be modified in other ways to make for a better food composition database for the convenience of users. of users.

  • Phytomedicines are believed to have benefits over conventional drugs and are regaining interest in current research. Moringa oleifera is a multi-purpose herbal plant used as human food and an alternative for medicinal purposes worldwide. It has been identified by researchers as a plant with numerous health benefits including nutritional and medicinal advantages. Moringa oleifera contains essential amino acids, carotenoids in leaves, and components with nutraceutical properties, supporting the idea of using this plant as a nutritional supplement or constituent in food preparation. Some nutritional evaluation has been carried out in leaves and stems. An important factor that accounts for the medicinal uses of Moringa oleifera is its very wide range of vital antioxidants, antibiotics and nutrients including vitamins and minerals. Almost all parts from Moringa can be used ad a source for nutrition with other useful values. This mini-review elaborates on details of its health benefits.

  • The purpose of this study is to prepare a systematic implementation of safety management for adult's foods through recommendations and guidelines for nutrition and hygiene standards for food quality certification system preferred by adults. To achieve this goal, the study studied the current status of adult preferred foods sold near the university, elicited the risks and problems of such foods, and selected nutritional and hygiene risk factors from those foods. To provide quality certification standards and guidelines for adult food preferences, this study looked at practical examples of relevant domestic and international policies and standards. The nutritional standards for food quality certification for sugars, fats, sodium, additive microorganisms and pathogenic bacteria, which are nutrients that can impair health when consumed in large quantities, and dietary standards limited to less than 100 kcal per serving were studied. One excessive amount of caffeine is reported to cause loss of calcium and potassium in the body, suggesting that if an adult is continuously exposed to high concentrations of caffeine, it could lead to imbalance in the resolution in the body and be flavored by growth and foot moon. Therefore, it is necessary to prepare an individual banner based on feasible food types, which is coordinated with the nutritional aspects that fit the purpose of presenting right amount, safe food through the quality certification system for adult's favorite foods and practical aspects that can induce companies' response and voluntary impacting efforts.

  • Improper disposal of herb residues in China has caused severe problems to the surrounding environment and human safety. Three herb residues, i.e., compound Kushen injection residues (CKI) and part one and part two of Qizhitongluo Capsule residues (QC1 and QC2, respectively), were used for the cultivation of Pleurotus ostreatus. The effect of the supplementation of corncobs (CC) with different herb residues on yield, nutritional composition, and antioxidant activity of P. ostreatus was investigated. Compared to the control, the higher mycelial growth rate was observed on substrates CC +30% CKI and CC +30% QC1, while the higher yield was obtained from substrates CC +30% QC2 and CC +30% CKI. Moreover, chemical analysis of fruit bodies revealed that the addition of herb residues to CC significantly increased proteins, amino acids, ashes, minerals (Na and Ca), and total phenolic contents but significantly reduced carbohydrates and $IC_{50}$ values of DPPH radicals. In addition, no heavy metals (Pb, Cd, and As) were detected in the fruiting bodies harvested from different substrate combinations. These results demonstrated that mixtures of CC with herb residues might be utilized as a novel, practical, and easily available substrate for the cultivation of P. ostreatus, which is beneficial for the effective management of herb residues.

  • This study assessed effective strategies to reduce the sodium intake among consumers using pork cutlet sauce as a model food system. Original pork cutlet sauce and sodium-reduced sauce (29% reduced by a salt substitute) were analyzed to characterize the sensory properties using descriptive analysis. The effects of sodium-reduction of the sauce, consumer type (nutrition teachers vs. general consumers), information related to the sodium content, serving method, and consumer's health, taste and sodium-related attitudes on the consumer's preference, perception, and intake of the sauce were analyzed using a consumer test. In descriptive analysis, the original and sodium-reduced sauce showed similar sensory characteristics but did not differ in saltiness. In the consumer test, there were no significant differences in the overall preference levels between the two sauces. On the other hand, there were significant differences in preference and perception between nutrition teachers and general consumer groups, which were due largely to their age as well as the health and sodium-related attitudes and nutritional knowledge differences. Sodium-reduced information decreased the perceived saltiness intensity. In addition, reducing sodium intake by serving pork cutlet sauce in a bottle can be an effective strategy because this serving method increased the acceptance and induced the smaller intake of sauce.
