  • This study was attempted to standard Yukwa recipies by proposing optimal conditions for soaking time and the number of beating. Soaking time and the number of beating had effects on the number of peak, implying that 15 days of soaking time at $15^{\circ}C$ and 160 times of beating would be required. In Yukwa's microstructural image, the better groups were over 15 days of soaking time and as number of beating increased, the appearance improved. The longer soaking time, the better tenderness and expansion volume. The number of beating had significant effects on all sensory evaluation except volume. Response surface model showed that the optimal condition would be at least 15 days of soaking and 319 times of beating.

  • Liquid smoke is made by concentration of smoke generated from charcoal of broad-leaved trees, or by refinement of smoke originated from incomplete combustion of wood condensate (Park et al., 1994). Generally, it is well known that phenol and its derivatives have antioxidative effect, while acids and formaldehyde have antimicrobial effect (Park et al., 1994). Meanwhile, some studies (Alonge, 1988; Dungel, 1961) reported that the high incidence of stomach cancer has been associated with the consumption of smoked fishes, and these were investigated to direct intake of fishes treated with smoke, containing polycyclic aromatic hydrocarbons(PAHs)(Moret et al., 1999).

  • Food waste is inevitable in any institutional food system. Although many factors contribute to plate waste, few quantitative studies of plate waste have actually been carried out. This study was undertaken to check (a) how the service style that affects the amount of plate waste, (b) the difference of plate waste between men and women and, (c) the influence of plate waste and customers'satisfaction to served meal. The survey was conducted through March 15 and April 9, 2000 by weighing the amount of plate waste and by questionnaires. Statistical data analysis was completed using the SPSS-PC program for descriptive analysis and ANOVA test. The results were as follows; (1) The largest amount, plate waste percentage measured were 19% of‘Hot alaska pollack soup’and 18% of‘Kuansh soup’respectively. (2) Amount of leftovers can be reduced if the pre-portioned serving style is changed to self-portioned serving. (3) The main reasons for leaving leftover were‘served too often’and‘disliked food’. (4) The customers'satisfaction rate was highly correlated with the leftover amounts.

  • People in Korea, a peninsular, have acquired a variety of marine food resources including seaweeds. Ecklonia stolonifera, a brown algae, is commonly dwelling in Korean coasts and their cultivation methods were developed for a mass-production. Recently, studies have revealed that Ecklonia stolonifera is a promising material for the development of health functional foods. In an effort to carefully review the current understating in the effects and mechanisms of Ecklonia stolonifera on liver functions by deduction from relevant literatures, the effective components were identified as phlorotannins, including dieckol, eckstolonol, eckol, phlorofucofuroeckol A, and phlorosterol. Their aiding action on the hepatic functions is categorized as follows. A) Regulation of oxidative stress by anti-oxidant capacity, B) Protection of hepatocytes from toxins, C) Prevention of alcoholic fatty liver and fibrogenesis, D) Regulation of chronic disease by improvement of inflammatory responses and lipid metabolisms, and E) indirect benefit conferred by a personal total wellness.

  • Although lisdexamfetamine is used as a recreational drug, little research exists regarding its potential for dependence or its precise mechanisms of action. This study aims to evaluate the psychoactivity and dependence profile of lisdexamfetamine using conditioned place preference and self-administration paradigms in rodents. Additionally, biochemical techniques are used to assess alterations in the dopamine levels in striatal synaptosomes following administration of lisdexamfetamine. Lisdexamfetamine increased both conditioned place preference and self-administration. Moreover, after administration of the lisdexamfetamine, dopamine levels in the striatal synaptosomes were significantly increased. Although some modifications should be made to the analytical methods, performing high performance liquid chromatography studies on synaptosomes can aid in predicting dependence liability when studying new psychoactive substances in the future. Collectively, lisdexamfetamine has potential for dependence possible via dopaminergic pathway.

  • BACKGROUND/OBJECTIVES: The concept of "food deserts" has been widely used in Western countries as a framework to identify areas with constrained access to fresh and nutritious foods, providing guidelines for targeted nutrition and public health programs. Unlike the vast amount of literature on food deserts in a Western context, only a few studies have addressed the concept in an East Asian context, and none of them have investigated spatial patterns of unhealthy food consumption from a South Korean perspective. SUBJECTS/METHODS: We first evaluated the applicability of food deserts in a Korean setting and identified four Korean-specific unhealthy food consumption indicators, including insufficient food consumption due to financial difficulty, limited consumption of fruits and vegetables, excessive consumption of junk food, and excessive consumption of instant noodles. The KNHANES 2008-2012 data in Seoul were analyzed with stratified sampling weights to understand the trends and basic characteristics of these eating patterns in each category. GIS analyses were then conducted for the data spatially aggregated at the sub-district level in order to create maps identifying areas of concern regarding each of these indicators and their combinations. RESULTS: Despite significant reduction in the rate of food insufficiency due to financial difficulty, the rates of excessive consumption of unhealthy foods (junk food and instant noodles) as well as limited consumption of fruits and vegetables have increased or remained high. These patterns tend to be found among relatively younger and more educated groups, regardless of income status. CONCLUSIONS: A GIS-based analysis demonstrated several hotspots as potential "food deserts" tailored to the Korean context based on the observed spatial patterns of undesirable food consumption. These findings could be used as a guide to prioritize areas for targeted intervention programs to facilitate healthy food consumption behaviors and thus improve nutrition and food-related health outcomes.

  • The Main objective of this study is to find consumer attitude toward the Sanitary Regulation of Foods. In view of consumerism, this result will be used in re-regulating the law. Among the Sanitary Regulation of Foods, this study focuses on the Standard of prepackaged Food Labelling, because it is related both with the advertising from the food manufacturer's point of view and with the perception about the food itself from the consumer's point of view. After reviewing the previous studies and related provisions about the Standard of Prepackaged food Labelling, and compare other sanitary regulation of foods in developed countries (U.S.A. and Japan), basic research framework was derived. The research framework focuses on the user perception about the validity of provisions about the Standard of Prepackaged Food Labelling, and on the existance of exaggeration in food advertising using prepackaged foods. Data were collected through questionaires from the sample covering 374 food customers. The data were analyzed by frequency test and the important findings of this study are as follows. Most food consumers consider such provisions as date of manufacturing, circulation time limit, cautions for food handling, price, and manufacturer as important factors in buying food products. Among these factors, the date of manufacturing and circulation time limit are most critical factors, and must be labelled correctly on the prepackaged food cover. But other provisions which do not affect on consumer's buying decision (e.g. business admission number, self standard number) need not be labelled. From this study, we can conclude that the provisions about the standard of prepackaged Food Labelling currently used must be devided into two parts. One is 'mandatory provisions' which must be obeyed by all food manufacturets, and the other is 'autonomous provisions' which need not be obeyed by all food manufacturers. And mandatory provisions need to be regylated more strongly than now.
