In the present study, we have evaluated cytotoxic effects, antitumor activities and metastasis inhibitory effects of Palsun brewing water in NIH 3T3 cells, human epitheloid carcinoma cells, and human skin melanoma cells. The light microscopic study showed morphological changes, AG-NOR (argyrophylic nucleolar organizer region) by silver chloride stain, and glycoprotein by PAS (periodic acid stain) reaction of the treated cells. Disruptions in cell organelles were determined by colorimetric methods; MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazoliumbromide) and SRB (sulforhodamine B protein) assays. These results suggest that Palsun Brewing Water retains no cytotoxic effects in NIH 3T3 cells and a growth-inhibitory activity in cancer cell lines.

The Takju brewing of raw rice starch was carried out by the simultaneous saccharification- fermentation using Rhizopus sp. koji and yeast, and compared with the Takju mash brewed by the conventional method. Rhitopus koji was prepared with uncooked rice for Takju brewing without cooking of rice starch. Alcohol concentration of Takju mash brewed with uncooked rice was slightly higher of 1.8% than that with cooked one. Amino acid contents was almost double and fuse1 oil contents was lower in uncooked brewing. The Takju mash prepared after fermentation without cooking of rice had a characteristic odor of raw material and a good quality of taste.

Influence of L. bu1garicus on the brewing of Takjoo by the use of commercial anylase and yeast was investigated. 1. The acidities of the mash in which L. bulgaricus was cultured at 45$^{\circ}C$ for 8 hours and 16 hours before the addition of yeast into mash were 11.6 and 13.9 (titration volumn ml with N/10-NaOH) respectively, which were slightly in excess of the nomal takjoo mash. 2. The best brewing product could be attained when L. bulgaricus was inoculated and fermented simultaneously with the yeast at 3$0^{\circ}C$. 3. When the commercial amylase and Lactobacillus were used in the brewing of Takjoo, the best condition of saccharification could be attained on the treatment of the amylase for six hours before the inoculation of Lactobacillus and yeast.

The purpose of this research was to find the most appropriate process for making yacon leaf tea. We applied both green tea and black tea brewing and fermenting methods for producing yacon leaf tea. This research included consumer test and descriptive analysis of professional trained panel on yacon tea tastes and flavors. Both consumer test and descriptive evaluation preferred yacon tea produced by black tea brewing and fermenting methods because it tasted less bitter and had a sweet, delicate taste. According to orthogonal transformation resulting from varimax rotation, first principal component was positively affected by black tea brewing and fermenting methods, while it was negatively affected by green tea brewing and fermenting methods. As a result, the study concluded black tea brewing and fermenting methods were appropriate for producing yacon leaf tea.

The method of yeast propagation has an influence on yeast physiology, fermentation ability, flocculation rate, and taste stability of beer. In order to find optimal conditions for propagation, several parameters were investigated in combinations. The bottom brewing yeast grown at $10^{\circ}C$ indicated that a higher flocculation capacity during the $1^{st}$ fermentation. However, the taste stability and the aroma profile were not affected by parameters of propagation investigated. The beer quality was rather affected by storage duration. In addition, a correlation between tasting and chemiluminescence was found at the beer, which was produced using bottom brewing yeast. The propagation at $10-25^{\circ}C$ with addition of zinc ion indicated the best condition to improve fermentation ability, flocculation rate, and filterability for bottom brewing yeast, whereas the propagation at $30^{\circ}C$ with addition of zinc ion showed the best condition to increase fermentation ability for top brewing yeasts.

The contents of“Joo-chan”consist of eighty two items about alcoholics, a number of side dishes and soybean sauces. Interpreted content was classified and analyzed. Selected 52 items among those brewages, artless-brewing alcoholics, were distributed into 6 large patterns. The materials used for brewing artless alcoholics were regular rice, waxy rice, wheat and yeast(NURUK). Six patterns, grounded on these materials, were set one thing to another and analyzed.

The contents of 6 classical records consist of 208 items about alcoholics and a number of side dishes; 44 items in YuckJooBangmoon, 82 items in Joochan, 19 items in the "sulbitnunbup", 24 items in Kyuhapchongsu from Korea university, and 39 items in Kyuhapchongsu. Interpreted content was classified and analyzed. Selected 27 items among those brewages, artless-brewing alcoholics, were distributed into 4 large patterns. The materials used for brewing artless alcoholics were regular rice, and yeast (NURUK) Four patterns, grounded on these materials, were set one thing to another and analyzed. analyzed.

The purpose of this study was to investigate the characteristics and brewing methods of Danyangju, which is one of the traditional single brewed rice liquors using Korean ancient literatures publishes from the 1400's to 1600's. Total 32 Danyangju products and 55 brewing methods were found by reviewing the ancient literatures. Danyangju products could be classified into four groups depending on type of grain used: 1) 13 Danyangju products with non-glutinous rice, 2) 14 products with waxy rice, 3) 4 products with mixture of waxy and nonwaxy rice, and 4) 2 products with barley. In this paper, not only ingredients, formula and utensils needed for preparation of Danyangju, but also brewing characteristics and terminology were reviewed. The findings on Danyangju in this study would be useful to improve the brewing methods and quality of Korean traditional liquors.

The research on the manufacturing procedure of Hosanchun jun in the classical literature(17 kinds) showed that the most usually brewed rice wine in it is the 3rd step rice wine, which is brewed by adding rice wine base to it at the intervals used quantity are as follows. Nonglutinous rice(88.2%), flour(82.3%), and nu-ruk(100%) are used in the 1st step of brewing, and nonglutinous rice(82.3%), glutinous rice(17.6%), flour(23.5%), and nu-ruk(11.3%) are used in the 2nd sep, and glutinous rice, flour, and 3rd step of brewing. The grains are used in the form of -paste(88.2%) in the 1st, and in the form of paste(64.7%) and steamed water-soaked rice(sul-bab)(29.4%) in the second step, and sul-bab(64.7%) in the 3rd step of brewing. Nu-ruk is used in small quantity in the 3rd step but it is used I somewhat larger quantity in the 2nd step of brewing.

This study was carried out to understand and analyze the cooking and processing methods presented in CHE MIN YO SUL, Chinese books of husbandary was written in sixth century. This book was composed of two parts-part I is Agricultural production and part II is product-Utilization. Especially, wines and yeast(NU RUK) written in part II were studied at this study paper. Most of yeast was made of barley and wheat. These materials had been prepared as raw, steamed, and roasted state by proper ratio with kinds of yeast and then fermented as dough state. Occasionally, various kinds of soup made from cocklebur, leaves of mulberry tree, wormwood etc. put into yeast dough. Yeast doughs were shaped round and square with or without hole in the center, made in July of the lunar calendar and fermented for 3 or 4 weeks. There were 43 kinds of wines in this book. Most of them were made of all kinds of cereals grown at that time-rice, waxy rice, millet, waxy millet etc. These cereals had been steaming or cooking gruel with grain or powder state and then fermented with yeast. These wines were prepared by single or double brewing methods and the kinds of double brewing wines were more than single brewing wines by two times. There were none of wines made from fruit and distilled wines. Generally, single brewing wines were not made in Apr., Nov., Dec., of the lunar calendar and double brewing wines were not made in Aug., Oct., Nov., of the lunar calendar. And ripenning periods of wine brewing were various, from 1 day to 7 months for single brewing, from 2 days to 8 months for double brewing.
