One hundred fifty grams of Korean fermented soybean paste and hot pepper-soybean paste were packaged in glass jar of 232 mL and Sotred at 5, 13, 22 and 30℃. During the storage, the changes in their microbial flora and quality attributes were monitored. Carbon dioxide production rate from the stored pastes were also determined from initial change of CO₂concentration in headspace of the pack. Hot pepper-soybean pate showed much higher CO₂ production rate higher dependence of CO₂ production on temperature compared to soybean paste. Total aerobic bacteria count and lactic acid bacteria count did not change significantly through the storage. Yeast count in soybean paste decreased slowly after initial uprise while that of hot pepper-soybean paste steadily decreased. Surface color of hot pepper paste changed to dark red with slight decrease in 'L' value and slight increase in 'a' and 'b' values, whereas any significant color change was not observed in soy paste. Titratable acidity increased with time with higher increase in soybean paste, but pH stayed at constant level for both pastes. All the rates of quality change were higher with higher temperature. Pressure buildup due to CO₂ production needs to be considered first in designing the packages of the fermented pastes before their color changes and other chemical quality changes.

Fernbraken is a popular and well-known wild grass, but the physiochemical properties of Korean Traditional pickling (Jangachi) during aging have been little reported. Therefore, this study was carried out to investigate the physiochemical properties of Fernbraken Jangachi treated with a soybean sauce mixture for 6 weeks (1st pretreatment) as well as fermented with soybean paste, red hot pepper paste and soybean sauce for 7 weeks. Total polyphenol contents, acidity, salinity, sweetness (Brix), and ${\alpha}$-tocopherol of Fernbraken Jangachi all increased with aging period. On the other hand, pH and total acidity of Fernbraken Jangachi did not change much. Among the three kinds of Jangachies, Jangachi fermented with soybean sauce showed 2 fold higher salinity and total acidity levels compared to the others. Therefore, the physiochemical properties of Fernbraken Jangachi were dependent on the pickling properties, such as soybean paste, hot pepper paste or soybean sauce, and these properties maintained a certain level after 5~6 weeks of aging. Further, proper aging period for Fernbraken Jangachi was suggested as 10 weeks.

Kochujang, a fermented hot pepper soybean paste, is a spicy condiment mixed with red pepper, boiled rice and mold fermented soybean (as koji) which is then fermented for several months. It has unique taste of hot, sweet, salty and savory flavor by all mixed ingredients by fermentation, and is one of most famous Korean traditional foods. The scale of the kochujang industry is about 200 billion won in Korea, and 7.8 million dollars and 4,500 tons in exports. Although it is still not a large part of the food industry in Korea, the scale of soy products will increase because it is a major subsidiary food in our dietary life and has grown from a homemade to a mass produced product. Kochujang has the largest market in the scale of sales among fermented soybean products and has merit because of its domestic base and its ability to grow to an international market due to its unique fermented taste. In order to make kochujang an international food, it Is necessary to study the scientific development of kochujang and the diversity of products using kochujang that are fitted to the taste of people around the world. In addition, participation in various exhibitions and food fairs supported by the government should help to promote kochujang throughout the world. In addition, these should be actively supported by the related businesses. Red pepper, a major ingredient in kochujang, has been widely studied and shown to have a positive effect on the reduction of fat, on the strengthening of the immune system, and on active biological functions. A fermented spice like kochujang has been shown to be beneficial for the body due to the process of fermentation rather than from the red pepper itself. If we prove the various biological functions of kochujang with a particular taste and flavor, it will energize a new market. It is necessary for business to make a continuous effort supported fly the scientific world and by government policy, in order to introduce this traditional food to the world. In the present day, the kochujang market is now on a firm basis and has been activated in the field of its study. Now, it is possible to achieve the birth of a secondary international market by concentrating on these efforts.

Kochujang, fermented hot pepper-soybean paste, was prepared by two common varieties of red pepper and natural fermented (NF) or pure cultured (PC) meju (soybean mass that is soaked, steamed, mashed and fermented by natural microflora or pure strain) and monitored their taste related component, enzyme activity and microflora during fermentation at $25^{\circ}C$ for 120 days for confirming possibility of kochujang fermentation control. The reducing sugars, amino type nitrogen (reference quality factor) and amino acid content in PC kochujang were 11.4%, 0.58% and 1,372.9 mg% respectively, 7.1%, 0.42% and 1,038.7 mg% in NF kochujang. It is concerned higher ${\alpha}-{\;}and{\;}{\beta}-{\;}amylase$ and, acid and neutral protease in PC kochujang during fermentation. The meju fermented by selected pure strain (A. oryzae CBU) can be applied to produced better quality of kochujang instead of natural meju.
