누룩은 생소맥을 조분쇄하여 물로 혼합시켜 자연적으로 공지중의 여러 종류의 미생물을 배양시켜 만들었다. 그러므로 누룩에서는 많은 종류의 사상균, 호모와 세균이 증식하였다. 누룩의 당화력은 원료 생소맥의 당화력과 대부분의 사상균의 당화력과 알붕의 세균성 당화력에 기인하여, 발효력은 누룩효모와 극소수의 사상균애 의하여 이루어지고 있다. 1945년 이전까지 누룩으로부터 12속 59종의 사상균이, 8속 29종의 효모와 4속 16종의 세균이 분리 되었다. 누룩사상균은 Aspergillus 속이 주종을 이루었고 Rhizopus속, Absidia속, Nucor속의 순으로 분포하고 있었고, Aspergillus속과 Rhizopus속은 중요한 누룩 당화균으로 작용하였다. 누룩의 대표적 효모는 Saccharomyces cerevisiae 이며 , 이균이 알코올 발효에 가장 큰 역할을 담당하며, Saccharomyces cerevisiae도 전통 민속주의 탁주와 약주의 발효역에 깊이관여한다고 사료된다. 누룩 중에 증식하는 세균은 양조학상 특별한 역할을 담당하지않지만 Bacillus 속 과 젖산세균이 많이 분리되었으며, 젖산세균은 담금초기에 pH의 안정화에 기여할 수 있다고 추측할 수 있다.

This study was carried out to investigate the effect of medium-cooked rice on brewing of yakju which was a traditional rice wine in Korea. The influences of cooking temperature of rice on hydrolysis of rice starch and rice protein were tested, and experimental brewings were done according to the traditional brewing method of Bangmunju in which some medium-cooked rice was used. The results obtained were as follows The hydrolysis of starch and protein in medium-cooked rice at 60~$65^{\circ}C$ was easier than that of full-cooked rice at 80~10$0^{\circ}C$. The amounts of saccharides, total amino acids and extracts In Yakju brewed with the combined use of medium-cooked rice and full-cooked rice were twice as much as those brewed with full-cooked rice only. The results of sensory test of Yakju brewed with the combined use of medium-cooked rice and full-cooked rice were better in taste, color and flavor than those brewed with full-cooked rice only. It was thought that our ancestor's traditional brewing method of Yakju in which medium cooked rice and full-cooked rice were used combinedly was excellent Judging from zymological point of views.

This study focused on the alcohol fermentability of traditional Nuruk, as well as yeast containing traditional Nuruk, in the production of Yakju. The fermentation performed with 30% Nuruk was effective with regard to alcohol yield. In addition, the fermentation containing 70% Nuruk showed the highest titratable acidity due to increased amounts of organic acids (succinic acid, oxalic acid, malic acid, acetic acid), which, however, negatively influenced the Yakju quality. Moreover, microbiological contamination always occurred in the fermentations using only Nuruk. In contrast, in the experiments with the yeast containing Nuruk, higher alcohol content and lower titrable acidity were obtained, independent of the Nuruk ratio used, positively effected the Yakju taste and flavor. Overall, the fermentation performed using the yeast containing 30% traditional Nuruk showed the best results for Yakju production.

The present study was performed to obtain data that could be used to popularize yakju(Korean traditional rice wine) by surveying how well rice wine goes with pairing foods. The survey was given to 302 men and women living in the Seoul and Gyunggi areas and work in the food service industry. The Jeon group, Gui group, Jeongol and Jjigae group, Pyeonyuk and Bossam group, and Muchim group were selected as menu items that go well with available rice wines. The survey aimed to identify foods that go well with four rice wines with different sensory characteristics. The survey results showed that both men and women replied that rice wines with Nuruk aroma and Nuruk taste go well with the Jeon group, rice wines with sour and flower aromas and common characteristics go well with the Muchim group, and rice wines with sweet and fruit tastes go well with the Muchim group. However, men and women had different opinions on rice wines having ginseng, soil, and herbal medicine aromas. Men replied that such rice wines go well with grilled meat, whereas women replied that these rice wines go well with Pyeonyuk and Bossan groups.

Objectives Studies on Chinese herbal injections are increasing. But, its safety are still not well reported. We have reviewed the literature related to the safety of Chinese herbal injection, especially those related to anaphylaxis. Methods The PubMed database was used to select the literatures related to anaphylaxis in China and to study the quality control and safety of Chinese herbal injection. Results Chinese herbal injection is a major traditional medical treatment in China, but it is the cause of adverse drug reactions including anaphylaxis. In order to solve this problem, various proposals have been made to identify the pharmacological and chemical causes of major side effects and to use them safely clinically. In addition, various researches have been conducted from preclinical to postmarketing surveillance to secure the safety of Chinese herbal injection. Based on this, it was found that various efforts are needed to secure the safety of bee sting needles. Conclusion In order to secure the safety of chinese herbal injections, it is necessary to identify the main mechanism of action and the pharmacological components contributing to it, and to develop a standardized formulation based on this. In addition, institutional pharmacovigilance is required.

Objectives : Records on medicinal liquor in medical texts and major culinary texts of the Joseon period were examined and compared to identify their relevance. Methods : Liquors that include medicinal ingredients in the Donguibogam, Sangayorok, Suunjapbang, Eumsikdimibang, and the Gyuhapchongseo and Juchan were collected. Similarities and differences of each entry were compared following thorough examination. Results : Direct citing of medical texts or specialized medical descriptions in the culinary texts or descriptions of medical liquor composed of various medicinals close to formula compositions are evidences that medical knowledge influenced culinary texts. Conclusions : Descriptions on medicinal liquor in medical texts and culinary texts could be said to have influenced each other.

This study was to investigate the characteristics of the Yakju fermented with differently-processed lotus leaves such as blanching, steaming, roasting, and drying, and fresh one for control. The total acid content was high (0.82~1.22%) in the lotus leaf Yakju, and lactic acid was the main compound among organic acids. Volatile acid content was high (200~500 mg/L) compared to the results of organic acid composition, and the main volatile acid in lotus leaf Yakju was acetic acid. Though the polyphenol content (616.5~693.1 mg/L) was similar among the Yakju, the Hunter's color value of those were quite different and also had a big impact on the sensory evaluation of color. Therefore, it seems that the enzyme activity of polyphenol oxidase in differently-processed lotus leaves may have an influence on the color of lotus leaf Yakju. In a sensory evaluation of color and aroma, lotus leaf Yakju fermentaed with fresh leaves and roasted ones were preferred to the others, and steamed leaves and roasted ones were the best in taste and overall acceptability.

Jinguiyaolue, written by Zhong-Jing Zhang(張仲景) in late Han(漢) Dynasty, is very foundamental Cannon of Oriental Medicine. Many Doctors commented on the book from Yuan(元) Dynasty in Chian and from Edo(江戶) Period in Japan, but there are a few studies in Korea. So we studied on the commentaries of the book, which published in the three countries, for improving research and education of it in our country.

This study was conducted to determine the influence of cultural conditions such as temperature, time, water content, koji-thickness and agitation on the production of saccharifying amylase by Rhizopus sp. ZB9 isolated from Korean Nuruk during the preparation of rice koji, which is used in brewing Korean rice wines, Takju and Yakju. Rice kojies were made under different cultural conditions, and the saccharifying activities of each koji were tested. The temperature range suitable for the production of saccharifying amylase was $28{\sim}36^{\circ}C$. Based on the saccharifying activity and color, 60 hours of cultivation at $28^{\circ}C$ was believed to produce the optimum results. The water contents of steamed rice suitable for the production of saccharifying amylase were 35~40%. An increase in koji-thickness induced no adverse effects on the production of saccharifying amylase, but agitation-work during cultivation had a harmful effect.
