Procyanidins, which are natural antioxidants and antimicrobials found in grapes, enhance the quality and extend the shelf life of meat. We explored the effects of edible films incorporating procyanidins on pork loin stored for various times. Procyanidins (0, 0.1, and 0.3%, w/w) were incorporated into the edible films. We assessed meat color, pH, levels of volatile basic nitrogen (VBN) and 2-thiobarbituric acid-reactive substances (TBARS), and microbial populations for 14 d. The chromaticities and pH values of pork loin wrapped in film containing procyanidins (0.1% and 0.3%) generally increased (p<0.05) with storage time. VBN and TBARS levels, and total bacterial and Escherichia coli (E. coli) counts, significantly decreased (p<0.05) in the procyanidin groups. In particular, procyanidins strongly inhibited TBARS formation. Thus, our findings suggest that edible film impregnated with procyanidins inhibits lipid oxidation and microbial growth, thereby enhancing the quality and shelf life of pork meat.

The purpose of this research was to investigate whether the perception of KPIs by restaurant managers from financial and non-financial perspectives was affected by BSC implementation. The perceptions that were examined were importance, adoption, performance, and utilization of KPIs. We surveyed managers from multinational restaurant chains that were adopting BSC and those that were not. From a non-financial perspective, the difference in perceived importance between BSC adopted firms and firms that did not adopt BSC was significant. The managers of BSC adopted firms perceived KPIs more seriously than the others. Secondly, according to the managers' working experiences, the difference of perceived utilization in the internal business process perspective was significant between BSC adopted firms and firms that did not adopt BSC. In addition, from the learning and growth perspective, the difference in perceived adoption and utilization between the two groups was significant. Finally, in the BSC adopted firms, the perceived importance of the managers affected the other perceptions like adoption and utilization from both the financial and non-financial perspectives.

The purpose of this study was to investigate consumers' utilization and satisfaction of the current food labeling system, their awareness of the nutrition labeling and its necessity, and their acceptance of the future enforcement of nutrition labeling. Questionnaires were distributed to 500 adult female consumers in Northern area of Kyonggi-do. Out of 402 questionnaires collected 358(89.1%) were analyzed using SAS computer program. The findings of this study were as follow: First, in the aspects of consumers' utilization and satisfaction of the current food labeling system, although they payed much attention to the food labels when they purchased food goods, the degree of their satisfaction in food labels was low. Among items in food labels they payed more attention to the expiration date, the date of production, and the name of manufacturer. However, the current food labeling system does not offer sufficient and reliable informations to consumers. Second, in the awareness of nutrition labeling and its necessity, majority of consumers appeared not to have seen the nutrition labeling in food products either domestic or imported. However, 93% of respondents answered that nutrition labeling is necessary. Third, in terms of the consumers' acceptance of enforcement of nutrition labeling, they were affirmative in bearing the increased costs, and their expectation to the beneficial effects of enforcement of nutrition labeling was stronger than worrying about the disadvantages or side effects of it.

The objective of this study was to investigate the effects of quality grade (QG) on the physicochemical composition and eating quality attributes of pork belly and shoulder butt. Seventy-two growing-finishing crossbred pigs were slaughtered and their carcasses were graded according to the Korean pork carcass grading system. Based on the grading criteria, the carcasses were classified into: QG 1+ (n=23), QG 1 (n=23) and QG 2 (n=26) groups. At 24 h postmortem, belly and shoulder butt cuts were collected from the QG groups and used for analysis of meat quality, flavor compounds and eating quality attributes. Results showed that the variation in fat content among QG was approximately 2% in the both cut types. The QG showed no effects on all the quality traits: cooking loss, pH and color of the belly or shoulder butt (p>0.05). Thirty-five flavor compounds comprising mainly fatty acids oxidation/degradation-derived products (e.g., aldehydes) and only few Maillard reaction-derived products (e.g., sulfur-and nitrogen-containing compounds) were identified. However, the QG showed a minor effect on the flavor profiles in both the belly and shoulder butt. Regarding the sensory quality, no effects of the QG were found on all the eating quality attributes (color, flavor, juiciness, tenderness and acceptability) for both the belly and shoulder butt cuts (p>0.05). Thus, it may be concluded that the current pork carcass grading standards do not reflect the real quality and value of the belly and shoulder butt cuts.

Two experiments involving comparative slaughter procedures were conducted to see if the decrease in total energy retention (ER) resulted from the decreased food intake in growing chicks fed on a diet containing tryptophan less than the requirement. Ad libitum-feeding a diet containing 50% of tryptophan of a control diet (1.5 g/kg) decreased body weight gain, apparent metabolizable energy intake (AMEI), ER and ER : AMEI ratio. When both the control diet and the 0.75 g/kg tryptophan diet were tube-fed at the two levels of food intake, body weight gain was significantly lower in chicks on the low tryptophan diet than in the control chicks at each level of intake. AME : gross-energy ratio decreased only when the low tryptophan diet was tube-fed at the higher level of intake. Energy retained as protein was significantly decreased by the low tryptophan level and reduction of food intake. Energy retained as fat was affected by food intake. ER and ER : AMEI ratio were unaffected by dietary tryptophan level and were proportional to AMEI. Heat increment of feeding was affected by neither tryptophan nor food intake. These results indicate that the decreased ER in chicks fed on the low tryptophan diet was due mainly to the decreased food intake and not to the decreased efficiency of ME utilization.

Agar-based composite films were prepared with variety of food processing and agricultural processing waste materials in order to screen natural lingo-cellulosic resources for the value-added utilization of the under-utilized materials. The effect of these waste materials (10 wt% based on agar) on mechanical properties, moisture content (MC), water vapor permeability (WVP), water absorption behavior of biocomposite films were investigated. Biocomposite films prepared with various fibers resulted in significant increase or decrease in color and percent transmittance. The MC, WVP, and surface hydrophobicity of biocomposite films increased significantly by incorporation of fibers, while the water uptake ratio and solubility of the film decreased. SEM images of biocomposite film showed better adhesion between the fiber and agar polymer. Among the tested cellulosic waste materials, rice wine waste, onion and garlic fibers were promising for the value-added utilization as a reinforcing material for the preparation of biocomposite food packaging films.

This purpose of this study was to contribute to the establishment of nutriton labeling and consumer education about food label by offereing basic information. Survey was carried out by questionnaire method. Subject groups were middle and high school female teachers and they were asked questions about their utilization and satisfaction of the current food labeling system, their awareness of the nutrition labeling and its necessity, and their acceptance of the future enforcement of nutrition labeling system. Questionnaires were distributed to 500 middle school female teachers in Chungbuk and Kyoggi area. Out of 340 reports(68%) collected, 311 reports(91.5%) were analyzed using SAS computer program. Most of the respondents payed much attention to the labels of the food at the time of purchase, the degree of their satisfaction in the current food labeling system was low. Concerning the awareness on nutrition labeling, Home Economics teachers knew better than non-Home Economics whether there were the regulations of nutrition labeling in Korea or not. Ninety-six percent of respondents answered that nutrition labeling is necessary. Home Economics teachers recognized the necessity of nutrition labeling more strongly than non-Home Economics teachers. Sixty eight percent of the respondents showed positive attitude to the actuation of nutrition labeling.
