  • The purpose of this study was to investigate the relationship between HMR use and eating habits in young Korean adults. This cross-sectional study was conducted on 575 adults (232 men, 343 women) in their 20s and 30s in Korea. Their use of HMRs (classified as ready-to-eat, ready-to-cook, and fresh convenience foods) and eating habits were surveyed. The main reasons for HMR use by men and women were convenience (54.7%, 64.4%) and promptness (24.2%, 24.2%), respectively. The most frequent place for HMR purchase was a convenience store (74.1% and 65.0%, respectively). Regarding the frequency of HMR use, 1~2 times a week was the highest for ready-to-eat (40.9%) and ready-to-cook (30.1%), while no eating was the highest for fresh convenience foods (41.0%). HMR preference was the highest (3.8 out of 5 on a 5-point scale) for ready-to-eat, followed by ready-to-cook (3.3 points) and fresh convenience foods (3.3 points). The use frequency and preference of total HMRs, ready-to-eat foods, and ready-to-eat foods were positively correlated with unfavorable eating habits, including unbalanced eating, overeating, salty eating, spicy eating, skipping, and irregular meals. However, fresh convenience foods showed negative correlations with unbalanced eating, overeating, and salty eating. The use frequency and preference of total HMRs, ready-to-eat foods, and ready-to-cook foods were positively correlated with undesirable eating habits. However, fresh convenience food showed a negative correlation with eating habits such as unbalanced, overeating, and salty eating. These results should be considered for favorable food production and consumer guidance to promote healthy food choices.

  • We investigated the effects of gamma irradiation on the microbiological, chemical and sensory qualities of bulgogi, a traditional Korean meat product. Gamma irradiation reduced the number of coliform bacteria and bacterial colonies counted in Salmonella-Shigella selective agar to a non-detectable level. Thermophillic microorganisms (mainly Bacillus spp.) in bolgogi refrigerated for 20 days were also significantly reduced by 3 log cycles by 2.5 to 7.5 kGy of irradiation, compared to the control. Electron donating ability and shear force of ready-to-cook bulgogi was not significantly affected by gamma irradiation. Irradiation increased the 2-thiobarbituric acid reactive substances (TBARS) value. The irradiated, raw, ready-to-cook bulgogi had significantly higher scores in color and appearance than those of non-irradiated controls from sensory evaluation. The overall acceptance of cooked bulgogi had higher scores in non-irradiated or 2.5 kGy-irradiated bulgogi than the 5.0- or 7.5-kGy irradiated counterparts. In conclusion, irradiation at 2.5 kGy is recommended as a method to improve shelf-life, safety, and to achieve acceptable quality of ready-to-cook bulgogi without any adverse changes in the sensory characteristics.

  • Objectives: The rise of one-person households may have consequences for food consumption patterns, and eating habits. This study investigated the home meal replacement (HMR) use and eating habits among adults in their 20s-30s living in one-person households. Methods: A total of 247 adults aged 26-39 years participated in this study. The subjects were divided into three group according to the household type; one-person households (n=80), two-person households (n=49), and multi-family (three and more members) households (n=118). Their use of HMRs (classified as ready-to-eat, ready-to-cook, and fresh convenience foods) and their eating habits were all compared. Results: The mean age of the subjects was 30.5 years, 47.8% were male, and there was no significant difference in age, gender, occupation, and monthly income according to the type of household. The intake frequency of total HMR and ready-to-eat foods was significantly higher in one-person households among the three groups. People in one-person households consumed more HMRs alone, and spent more money to buy HMRs. Undesirable dietary habit scores like unbalanced eating (p<0.05) and eating salty foods (p<0.05) were significantly higher in the one-person households. Among the total subjects, the unbalanced eating scores showed a significant positive correlation with the intake frequency of ready-to-eat foods, while the unbalanced eating scores showed negative correlation with the preference of fresh convenience foods. The scores for eating salty foods showed a significant positive correlation with the intake frequency and preference of ready-to-eat foods and ready-to-cook foods, while there was negative correlation with the intake frequency and preference of fresh convenience foods. Conclusions: Adults in their 20s-30s in one-person households consumed more ready-to-eat foods than those in multi-family households. In addition, people with one-person households had more unbalanced diets and ate more salty foods, and these undesirable eating habits showed a significant positive correlation with the use of ready-to-eat or ready-to-cook foods. These results should be addressed for producing healthier ready-to-eat/ready-to-cook foods and implementing nutrition education for making healthy food choices of one-person households, which are steadily increasing.

  • In this study, ready-to-cook (RTC) pork bulgogi was investigated microbiologically to determine contamination levels. The investigation was conducted because of an increasing trend in the consumption of RTC meat products in Korea. Ninety marinated RTC pork bulgogi samples were collected from major retail outlets (M), department stores (D), and local markets (L) in Seoul, Korea from March to June 2011. This study examined total plate counts (TPC), Escherichia coli, and coliform bacterial counts, and the presence of Bacillus cereus, Staphylococcus aureus, Listeria monocytogenes, Salmonella spp., and E. coli O157:H7. The mean TPC values were 5.89, 6.08, and 5.89 Log CFU/g for M, D, and L, respectively. E. coli was not detected in any sample, but coliforms were present in 72 (80%) of the 90 samples collected. B. cereus, E. coli O157:H7, and Salmonella spp. were not detected; however, S. aureus and L. monocytogenes were detected in five (5.5%) and one (1.1%) of the 90 samples. Samples collected from M and D were contaminated with S. aureus and those from L with L. monocytogenes. These results demonstrate that the conditions under which RTC pork bulgogis are handled and processed are unsanitary.

  • Here is a research on hospital foodservice system, when korea traditional food of pyeon yuk and bin dae deok were used by ready-prepared foodservice system, it was estimated the preservations of microbiological quality and sensory quality. All data collection was replicated three times. The results were as following; 1. In time and temperature data, two menu items were needed internal temperature below $7^{\circ}C$ in a cooling stage, and in the case of cook/chill storage, the days were shortened within weeks, and the holding time must be possiblely minimized. Finally foods were served sanitary. 2. In view of microbiological safety, in the case of cook/chill storage as $0{\sim}4^{\circ}C$ the days must be shortened within 2 weeks and its was possible to store until 6 weeks in $-20{\sim}-23.3^{\circ}C$. So to preserve pre-cooked food longly, it was effective to freeze them quickly by using vacuum package and to reheat them by a microwave oven before serving and to serve lastly in microbiological quality. 3. Hospital ready-prepared foodservice system with food storage in plastic bags, biochemical test of C. Perfingens C. botulinum and Salmonella were not detected. 4. By using of a microwave oven, it had effects of thawing, reheating and sterilizing of chilled and frozen foods in a short time. 5. Sensory evaluations were made by a 10-member panel using five scoring tests. Because sensory of quality was lowered in the case of chilled storage, it was possible to serve foods within 2 weeks. Texture and aroma were preserved by cook/frozen system and usually there was no significance from 4 weeks until 6 weeks, but considering of the objects, it was good to store until 4 weeks in sensory quality.

  • The purpose of this study was to evaluate the Quality characteristics, and was conducted to develope consumer preference of the frozen ready prepared eels by cooking method between 100 Korean (male 48, female 52) and 105 Japanese (male 43, female 62) who visited Korea. The consumers' responses about frozen ready prepared eels were measured on 9 point likert scale. In the preference test of cooking method for ready prepared eel, the Japanese and Korean preferred gas grill products in conger eel. Charcoal grill for Anguilla japonica products was estimated the most preferred cooking method by Japanese. In comparison between Japanese and Korean, Korean preferred more gas grill products than charcoal grill in Anguillajaponica products. The results for this factor were very significantly different in relation to appearance and overall acceptance of sensory characteristics (p<0.0l). The steaming products was estimated to be more delicious by Japanese than Korean. The results for this steaming products were very significantly different in evaluation of appearance, taste and overall acceptability between Japanese and Korean (p<0.05 or p<0.0l). In the domestic consumer test, the overall acceptability of eel product with ginseng and pine mushroom were 6.84 and 5.56 respectively. In the Japanese consumer test, the overall acceptability of eel product with ginseng and pine mushroom were 5.62 and 6.49 respectively. Consequently, Korea consumer preferred gas grill method for both conger eel and Anguilla japonica products added by ginseng flavor in sauce. Japanese preferred gas grill method for conger eel, charcoal grill method for Anguilla jap on ica added by pine mushroom flavor in sauce. Therefore, it is needed to study for the development of conger eel's sauce and cooking method proper to preference of Korean and Japanese in foodservice operations.

  • The purposes of this study were to conceptualize the Home Meal Replacement (HMR) in Korea and to gather professionals' opinions of prospect and task for HMR industry in Korea. A total of 67 experts participated in a three round survey by Delphi technique, which was used to integrate and share the each expert's professional idea. According to the result, HMR was translated into 'Gajeongsiksa daeyongsik' in Korean and given definition to 'a meal taken directly or through brief cooking process at home by purchasing ready to eat or ready to end-cook type of food'. As the result of categorizing HMR products of Korean food, 'I. Ready to eat' such as side dishes, kimchi, salad, sandwich, kimbab, and so on and 'II. Ready to heat' such as rice, porridge, retort food (soup, broth, curry, spaghetti, etc.), frozen pizza, grilled food, jabchae, instant soup, and so on were construed in a limited sense of the HMR. In addition, 'III. Ready to end-cook' such as frozen dumpling, frozen pork cutlet, seasoned meat, powder-type soup, and so on as well as these two kinds were interpreted in a broad sense of the HMR. In the prospect of HMR industry in Korea, the Korean HMR industry would develop continuously accompanied by increasing of consumers using HMR products. Introduction and generalization of HMRs would serve the convenience for meal preparation and then influence the change of home meal pattern. Nevertheless, it was concerned about that using HMRs might have limitation on solving the problems of dietary life including irregular meal, skipping a meal, and so on and influence the nutrition imbalance. For the development of HMRs, developing various menu and the packaging materials for HMR products, constructing the thorough sanitary management, and strengthening R & D for the HMR of Korean food were the future tasks in Korean HMR industry.

  • Bacillus cereus is food poisoning bacteria frequently occured in starch food. Most of the delivery foods for infant is classified as ready-to-cook food. But unlike food for infant and young children, there are no standards and specifications of Bacillus cereus in ready-to-cook food. The purpose of this study is to examine the presence of Bacillus cereus, aerobic bacteria and coliforms in the food for infant and young children sold through internet. B. cereus was detected in 9 samples (8.3%), total aerobic bacteria was detected over $10^6CFU/g$ in 4 samples and coliforms were not detected in any samples. This will provide basic data for standards and specifications of Bacillus cereus in ready-to-cook food.

  • The purpose of this study was to assess the sugars contents of home meal replacement (HMR) products currently sold in Korea. This study surveyed and examined the sugars contents in 835 popular HMRs (294 ready-to-eat foods; RTE, 499 ready-to-cook foods; RTC, 42 fresh-cut vegetables; FCV) through the nutrition labels. The average price, weight and energy content of 835 HMR products were 3,917.5 Korean won, 336.0 g, and 522.7 kcal, respectively. The sugars content per product was significantly higher in the RTCs (13.4 g) and RTEs (10.3 g) than that in the FCVs (4.2 g) (P<0.001), and the percentage of energy from sugars was 9.7% for the RTEs, 10.2% for the RTCs, and 8.7% for the FCVs without any significant difference. The sugars contents of 9 RTE types were in the order of side dishes (34.3 g), sunsik (22.5 g) and hamburgers (12.1 g) per package. The percentage of energy from sugars was highest in side dishes (28.1%), followed by kimchi (24.9%), sunsik (17.2%), and hamburgers (10.6%). Among 14 RTC types, the sugars contents were in the order of hot dogs (52.9 g), tteokbokki (30.4 g) and noodles (21.2 g) per package. The percentage of energy from sugars was the highest at 22.9% for sauces, followed by side dishes (17.3%), porridges (14.4%), instant stews (14.3%), and hot dogs (13.1%). Strategies and practices are needed to reduce the sugars contents of HMR producers and the sugars intakes of HMR consumers.
