There are two kinds of commercially available ginseng root, red ginseng and white ginseng processed from fresh ginseng root Those ginsengs are primary product from fresh ginseng root and have the characteristic of keeping their original root shape Processed ginseng products are made from either red ginseng or white ginseng by way of complicated process of pulverization. Extraction. Condensation, fettering, sterilization, etc. Among them there are extracts. extract powder, powder, capsules tablets, Candy, drinks, nectar, jelly, gums. chicken soup. tonic. etc. to meet the demand for consumer's pretheronce . The 200 kinds of processed secondary products are approximately produced in the form of 20 kinds of ginseng products by about 60 domestic companies. In spite of about 213.000 million won of domestic market in 1993. it seems like that the ginseng market of the future has not a good prospects The total market sale of white ginseng in Korea has been continuously decreased since 1991 And 963 tons of white ginseng was consumed in domestic market in 1993 The domestic market sales of white ginseng in origina1 root shave. was 90, 000 million won in 1993 and market price of the fine root used as a source of processed products has not been changed in these ten years. The total market sale of red ginseng and its processed products was 58, 000 million won in 1993 9.800 mi11ion won of red ginseng in original root shape and 48.000mi11ion of processed red ginseng product. Ginseng products such as extracts, drinks, teas and tonics etc atre mostly exported to south-east Asia. And the total exports of ginseng pi.oducts (extracts, drinks teas) decreased to 54 million dollars in 1994, compared with 85 million dollars in 1992. Despite of extensive knowledge about ginseng little is still known about the development of new processed ginseng pl.oducts because of "Know-How". Some papars have presented the effects of extracting method(amounts of solvent. time. temperature, equipment. etc.) on the quality and yields of ginseng extr acts. Also. some researchers have carried out a few studies on the poriflcation of the extracts and the amounts of precipitation in the drink at variotas pH during the storage for preventinly drink from precipitation. A fell studies on the preservation of Korean ginseng powder. tea. Extract powder by irradiation and ozone treatment have been reported by some researcher for the improvement hygienic quality of ginseng products There are also some reports about the effects of ginseng components on the acid production by lactic acid bacteria or acetic acid bacteria. and alcohol production by yeast for the development of new ginseng products processed by fermentation. To make ginseng more able to contribute to the health of mankind in the future. consistent and considerable efforts should be focussed on improving the taste of ginseng and developing various new product as a health food or a function food.tion food.

When globalizing Korean food, it is important to conduct regional consumer research before entering the market so that an effective market strategy can be developed. This study was conducted to compare the perceptions regarding Thai, Chinese, Japanese and Korean food between Swedish and Yugoslavian university students in $V{\ddot{a}}xj{\ddot{o}}$, Sweden, where regional market research is lacking. As immigration increases worldwide, comparison of consumer perceptions of immigrants and domestic individuals will provide meaningful insight for use in the development of marketing strategies for areas where immigrant populations are increasing rapidly. In this study, six attributes of Asian food, fresh vegetables, low fat, chicken and sea food, exotic ingredient, value for money and unknown food, were compared. The perception of fresh vegetables and low fat of Chinese food differed significantly among the two groups. Because both of these attributes are health related, these findings indicate that recipe modification may be necessary to adapt to the preferred taste of target customers in this prospective market.

This study was carried out to obtain information about preferences of the meat food in 491 Koreans including the ones living in New Zealand. General preference for the meats was not significant differences according to sex, monthly income level, residing area, marriage status and family number. Degree of preferences for the meats which have consumed commonly such as beef, pork and chicken showed relatively a high tendency, but the meats such as goat, lamb, deer and turkey were very low in preference score. In the meats cooking style, most subjects preferred Korean style followed by Chinese and western style. The younger had a high score than the older inpreference of the processed meats. The meat foods subjects preferred were Tzeams, Kui, Tangs, cutlets and Tangsuyuks. There were not significant differences in preferences for the meats between Korean living in domestic and New Zealand. This study showed that the meat foods which theirs preference was high have had a high tendency in the intake frequency also. Preferences for the meat food was affected by intake frequency and amount of intake and nutritional knowledge, but not related to BMI, health status and monthly income level.

A mysterious disease with vesicle-like nodules in dairy cattle udder has been drawn attention to the foreign animal disease expert at the National Veterinary Research Institute. Immediately dispatched foreign animal disease expert, pathologist and regional veterinary officials executed quarantine nearby affected farm area to prevent transmission of the pathogen which was possibly contagious vesicular disease agents in domestic animals such as FMD or SVD. Proper samples were collected for the laboratory examination. Vesicle-like lesions were only detected in lactating dairy cattle and no distinct clinical signs have been observed in affected animals. Parapox and papillomavirus particles have been demonstrated on electromicroscopical examination from nodular samples of udder lesions of the dairy cattle. Characteristic papilloma virus particles with 55nm in diameter and parapoxvirus with 150nm in diameter and 350nm long oval shape particles were detected and confirmed by embryonated chicken egg inoculation.

This study investigated the epidemiology of Listeria (L.) monocytogenes, a food-borne pathogen. The epidemiology of food-borne pathogens is of great importance for clarifying bacterial origin and preventing bacterial contamination and infection. This work examined 68 L. monocytogenes strains, including 11 reference strains and 57 isolates from imported US beef, domestic meats (beef, pork, chicken meat), raw milk, and milk plants. The random amplified polymorphic DNA (RAPD) techniques were optimized to develop a standard molecular epidemiological analysis of L. monocytogenes. There was great genetic variability among the isolates, which produced 24 and 34 RAPD patterns with primer HLWL85 and HLWL74, respectively. The discriminatory power of the RAPD methods with HLWL85 and HLWL74 primer were very high (DI = 0.957; S ${\geq}$ 80%, S ${\geq}$ 95%). Some RAPD types were specific to origin. A few RAPD types were specific for L. monocytogenes strains belonging to a particular serotype. Using the HLWL85 primer, the strains isolated from milk plants could be distinguished from the other strains. And using the HLWL74 primer, the strains isolated from imported beef (US) could be distinguished completely from the other strains.

We analyzed the contents of 12 types of minerals such as calcium in muscle from various species. Thereafter we observed changes of the concentrations according to age, part and sex in major domestic animals. The concentrations of calcium, iron, sodium, potassium, magnesium and zinc were high respectively whilst the content of cobalt, chromium, copper, manganese, molybdenum and nickel were low respectively in the muscle. The concentration of calcium was high in duck and dog but low in pig and horse. Also high level of sodium content was detected in dog and the content of potassium, iron showed high level in horse compared with the content in other animals. In 6 types of microminerals as cobalt, the level of muscle were no more than 1 ppm showing very low content in all animal, but $2.99{\pm}0.85$ppm of copper in duck was an exceptional case. According to the age some species showed small range of variation centering on macrominerals and there was no remarkable change in microminerals. Distribution of minerals was different according to the part and the variation was very diverse compared with other factors such as age and sex. Additionally, the content of minerals in muscle was higher in female than in male chicken and duck. In conclusion, the difference of the content of minerals according to the species was mainly focused on macrominerals.

This study was undertaken to investigate the perception and the consumption behavior for the meats in Koreans. The subjects were 491 Koreans including the ones residing in New Zealand. Most of subjects answered the meats are used for supper time. The frequency of the meats intake was affected by education and monthly income level. 69.2% of the subjects had positive response such as increased stamina and fulled stomach for psychological state after the meats intake. The use of meats recently revealed that 48% of the subjects have decreased its consumption. The main reasons diminished the use of meats were for the good health and economic state. Women were found to avoid the meats fat to a greater degree than men. The kinds of the meat used frequently were beef, pork and chicken. The younger tended to higher the frequency of the processed meats intake than the older. According to 3 level of BMI of the subjects, there were significant differences in the amount of the meat intake and perception for necessity of the meat. This study showed that the higher the preference for meat, the education and the monthly income level, the more the meat intake frequency. There were not significant differences between Koreans residing in domestic and New Zealand except the dog meat in the perception and consumption of the meat.

This study empirically analyzed the welfare effect of the military purveyance program, which plays an important role in maintaining the sales channel and demand base in Korea's agricultural and livestock industry, as well as the stable supply of safe ingredients for military meals essential for the morale and combat power of soldiers. The military purveyance program causes additional demand for domestic livestock products, affecting the trading volumes and price levels in the market. This will change the welfare of producers and consumers, and affect the welfare of soldiers who are subject to military meals. The analysis results obtained through a simulation method based on the equilibrium displacement model are as follows. In the case of pork delivered for military service, producer surplus increased by KRW 55.3-62.2 billion and consumer surplus decreased by KRW 55.1~62.0 billion based on pork production in 2021. It wad analyzed that the consumer surplus in the military supply market, rather than the conventional market, increased by KRW 96.9 billion won, resulting in a total welfare gain of KRW 97.1 billion.
