Viscosity is critically important for bulgogi sauce. However, exposure to irradiation may decrease the rheological properties of bulgogi sauce. This study was conducted to compare the effects of gamma irradiation (0-9 kGy) on viscosity, molecular weight, pH, reducing end level, and water solubility of xanthan gum, guar gum, and locust bean gum as thickening agents/stabilizers in bulgogi sauce. The physicochemical properties of all samples changed (p<0.05) from 3965 to 0 cP (viscosity), from 6048 to 28 kDa (molecular weight), from 5.79 to 4.62 (pH), from 0.13 mg/mL to 1.72 mg/mL (reducing end level), and from 6% to 87% (water solubility) following gamma irradiation. Viscosity after irradiation was most stable (p<0.05) in xanthan gum (from 1249 to 92 cP) compared with guar gum (from 3965 to 0 cP) and locust bean gum (from 1631 to 0 cP). The sensory properties (texture and taste) of bulgogi sauce prepared with xanthan gum (1%, w/w) were highly maintained (about 7.0-5.0) after high-dose irradiation of up to 40 kGy. These results indicate that xanthan gum can be effectively used as a thickening agent/stabilizer in bulgogi sauce, which had low viscosity after irradiation.

To evaluate the vancomycin resistance of Enterococcus spp. (VRE) from Saengsik and Sunsik, Enterococcus were isolated and identified from 25 Saengsik and 35 Sunsik samples, and resistance of Enterococcus to other antibiotics was also assessed. Thirty nine Enterococcus, 16 strains from Saengsik, and 23 strains from Sunsik, were ultimately isolated. The most frequently collected Enterococcus isolates in Saengsik were E. casseliflavus and E. hirae, and were E. casseliflavus and E. faecium in Sunsik. However, E. faecalis was not detected in those foods. Minimum inhibitory concentrations of vancomycin against the isolates were below $4\;{\mu}g/mL$ and no strains evidenced profound levels of resistance. The isolates were found to be susceptible to vancomycin with the exception of eight E. casseliflavus and three E. gallinarum. All Enterococcus isolates proved resistant to streptomycin and chloramphenicol. 23% of the isolates were resistant to penicillin; however, all of the isolates were sensitive to tetracycline. Six and 48%, respectively, of the strains from the Saengsik and Sunsik proved resistant to erythromycin. All of E. mundtii and E. hirae isolates from Saengsik, and 20% of E. gallinarum and E. casseliflavus isolates from Sunsik were found to be ampicillin-resistant. All of E. gallinarum, E. casseliflavus, and E. faecium were rifampin-resistant. The antibiotic resistances of Enterococcus were relatively low, and this low vancomycin resistance was similar to that evidenced by Enterococcus isolates obtained from the other foods. However, there may be a need for some review of the accepted antibiotics criteria for Enterococcus and VRE in ready-to-eat foods.

The broiler industry in Korea has been gradually changing its structure of independent operation into integrated and coordinated production and marketing system. It was in 1960s when the broiler industry first tried the integrated effort, but never succeeded as it was expected since due mainly to growers' attitudes favorable for traditional operation and agribusiness' passive response on structure change. Until mid 1980s, however, a bit of partially integrated system had been evolved by several factor suppliers. Recent years have furthered its progress toward completely integrated pattern, the ultimate goal of broiler integration. It is true that the external factors including the GATT Negotiations through the Uruguay Round stimulated the people involved in the industry to find the way of making it competitive to survive in the open, liberalized world economic system rapidly emerging through the process of globalization. Once the industry realized the necessity of reducing the cost of production and improving the quality of it, the conclusion tended to come to the point of an entire structural alteration by means of integration rather than an improvement of a certain segment such as marketing. It is very obvious. therefore. that the movement toward the complete integration will speed up in a coming few years under the leadership of not only entrepreneurs but also producers group. According to a report. there were three almost complete integrators and thirteen partial integrators as of December, 1990, all of which eagerly directed toward the completely integrated system in due course . Among others as an advantage of integrated structure. the cost saving must be pointed out as the greatest one In a survey, it was estimated that the cost of dressed and ready-to-eat chicken could be lowered by 31.8 percent and 41.5 percent, respectively, over that to be under the independent, non-integrated system. As long as everybody concerned about the future of the industry in the open market mechanism realizes the importance of the structure change through an integration, the broiler sector of Korean agriculture shall be moving toward the direction of vertically and completely integrated structure in order to make it competitive, even to export, hopefully before 1995 or by the end of this century in any case.

즉석 편이식품에서 위해도가 가장 큰 C. sakazakii와 S. enterica Typhimurium을 박테리오파지로 제어하기 위하여 용균성 박테리오파지를 분리, 동정하였고 조제분유와 채소 주스에 이들 세균에 적용하여 그의 효과를 분석하였다. 박테리오 파지는 돼지 분변에서 C. sakazakii와 S. enterica Typhimurium균을 용해시키는 박테리오파지를 분리하였고 현미경과 그의 특성을 분석, 동정하였다. Cronobacter에 작용하는 ES2 파지와 Salmonella의 ST2 파지는 형태학적 특성이 각각 Myoviridae와 Siphoviridae로 각각 동정되었으며 제한효소지도와 SDS-PAGE 분석에 의하여 서로 다른 파지임을 확인하였다. ES2 파지의 경우 latent period는 약 40분 정도였으며, ST2 파지는 약 30분 정도를 나타냈으며, burst size는 ES2 파지는 약 $52{\pm}5PFU/cell$, ST2 파지는 약 $21{\pm}3PFU/cell$로 나타났다. 열안정성은 $60^{\circ}C$에서 ST2 파지의 경우 100분 동안 안정한 것으로 나타났으나, ES2 파지는 30분 이후부터는 확인되지 않았다. 따라서 ST2 파지가 ES2 파지에 비해 열안정성이 높은 것을 알 수 있었다. 이 분리 파지를 조제분유와 채소 주스에 직접 적용한 효과는 ES2에 의한 Cronobacter 제어는 접종 후 6시간까지는 균수가 일정하게 유지하였고 균의 증식을 일어나지 않는 것으로 나타났다. ST2 파지에 의한 Salmonella는 생육저해가 잘 일어나 접종시간이 지남에 따라 균수가 감소하는 것을 확인하였다. 그러므로 C. sakazakii와 S. enterica Typhimurium의 생육저해는 이들 용균성 박테리오파지를 활용하여 가능한 것으로 보인다.

Purpose: Needs for reevaluation of food code standards and regulations for cooked foods produced in restaurants and institutional foodservice to minimize risk factors leading to foodborne outbreaks are on the rise. The purpose of the study was to propose updated standards for cooked foods of restaurants by testing whether or not experts agree to include them as a standard. Methods: Qualitative and quantitative research methods were applied via a survey by email and workshop hold for experts panel discussions. Results: Seven newly proposed standards were selected as follows: (1) sanitizing vegetables and fruits with no heating process after washing, (2) rapid cooling of cooked foods after heating process, (3) monitoring cooking temperatures, (4) minimum 2 hours holding after cooking for temperature control of safety (TCS) foods without temperature control, (5) banning practices for workers such as bare hands handling of ready-to-eat foods, (6) maintaining cleanliness of food contact surfaces for disposable products, and (7) cold holding standards for sushi. Conclusion: The proposed proposal can be utilized as control measures for preventing foodborne illness in restaurants. However, a feasibility study should be conducted to test whether they are applicable to the field of restaurant operation.

The effect of solid content on the physicochemical properties of rice porridge after reheating. The concentration of rice porridge was classified as solid content (12%, 10%, and 8%) by traditional Korean cooking methods. For reheating, packed rice porridge was boiled in water for 3 min and then cooled at room temperature ($25^{\circ}C$). The viscosity, soluble solid content and reducing sugar content of the rice porridge increased according to the solid content, while the blue value decreased. After reheating, the viscosities ($25^{\circ}C$) of all rice porridges decreased to 2.9-8.4%, compared to those of freshly made rice porridge, whereas the soluble solid content and reducing sugar content increased inversely according to the solid content of rice porridge. The SDI (starch digestion index) increased according to the solid content, whereas SDS (slowly digestible starch) the lowest in the solid content 12% porridge. Based on these results, it is favorable that the viscosity decrease after reheating was to be considered to ready-to eat rice porridges preparation.

The food choices in childhood have high a probability of being carried through into their adulthood life, which then contributes to the risk of many non-communicable diseases. Therefore, there is a need to gather some information about children's views on foods which may influence their food choices for planning a related dietary intervention or programme. This paper aimed to explore the views of children on foods and the types of foods which are usually consumed by children under four food groups (snacks, fast foods, cereals and cereal products; and milk and dairy products) by using focus group discussions. A total of 33 school children aged 7-9 years old from Selangor and Kuala Lumpur participated in the focus groups. Focus groups were audio-taped, transcribed and analyzed according to the listed themes. The outcomes show that the children usually consumed snacks such as white bread with spread or as a sandwich, local cakes, fruits such as papaya, mango and watermelon, biscuits or cookies, tea, chocolate drink and instant noodles. Their choices of fast foods included pizza, burgers, French fries and fried chicken. For cereal products, they usually consumed rice, bread and ready-to-eat cereals. Finally, their choices of dairy products included milk, cheese and yogurt. The reasons for the food liking were taste, nutritional value and the characteristics of food. The outcome of this study may provide additional information on the food choices among Malaysian children, especially in urban areas with regard to the food groups which have shown to have a relationship with the risk of childhood obesity.

Objectives: The purpose of this study was to determine whether eating non-home-prepared meals (NHPM), including fast food, ready-to-eat foods, and frozen foods, was associated with self-reported infertility in the United States women. Methods: Data on diet and infertility from women aged 20-49 years who participated in the 2013-2014 and 2015-2016 National Health and Nutrition Examination Surveys were analyzed (n=2143). Dietary information, including the number and types of NHPM consumed, was obtained from a self-reported questionnaire, and infertility status was analyzed using the following question, "Have you ever attempted to become pregnant over a period of at least a year without becoming pregnant" Results: The frequency of NHPM consumption was positively associated with self-reported infertility after adjusting for confounding effects (odds ratio [OR], 2.82; 95% confidence interval [CI], 1.48 to 5.38 of >1 vs. 0 NHPM/d). The odds of infertility were 2-3 times higher in women who consumed fast food than in those who did not consume fast food (OR, 2.73; 95% CI, 1.15 to 6.48 of >1 vs. 0 times/d). Conclusions: The frequency and types of NHPM may be a factor contributing to infertility. Although our findings require confirmation, they suggest that eating out may be deleterious to women fecundity.
