This study was conducted to standardize ingredient ratio and preparation method of mafor traditional special kimchies in kyungsang province, korea. There were about 35 varieties of special kimchi in Kyungsang province. Six varieties of them such as burdock kimchi, wild leek kimchi, green thread onion kimchi, perilla leaf kimchi, Godulbaegi(Korean wild lettuce) kimchi, and red pepper leaf kimchi were selected, because they tasted good and the physiological functions of their main ingredients were excellent. The ingredient ratios of the selected special kimchi were standardized through surveying hereditary preparation of some families in kyungsang province and using the literatures including cooking books. The standardized ingredient ratio of the burdock kimchi was 15.1 pickled anchovy juice, 6.8 red pepper powder, 5.7 garlic, 2.2 ginger, 18.0 rice flour paste, 13.5 green thread onion, and 1.2 sesame seed in proportion to 100 of burdock. The standardized preparation step of the selected special kimchies was similar except some preprocessing methods of main ingredients. The diagonally cut-up burdock ws usually parboiled or soaked in salted water, then it was mixed with the other ingredients. Wild leek and green thread onion were usually pickled with salt or pickled anchovy juice. Sometimes the green thread onion pickled was dried in the sun. General preprocessing of perilla leaf, Korean wild lettuce, and red pepper leaf was soaking them in salted water for about 5-10 days. Sometimes red pepper leaf was heated with steam and dried in the sun, then it was mixed with the other ingredients.

The purpose of this study was to investigate the preferences, consumption, and eating frequencies of housewives for commercialized traditional basic side dishes. The investigators visited 18 food markets and questionnaires were distributed to 464 housewives in the Busan area. The number of basic side dishes being sold at the markets were in the order of seasoned dried radish (17 markets; mk), salted garlic stalk (15 mk), braised black soy beans (14 mk), braised peppers and dried anchovies (13 mk), and braised lotus roots (12 mk). The housewives' order of preferences was for stir-fried dried anchovies, braised peppers and dried anchovies, braised seasoned beef, salted perilla leaf, and perilla leaf kimchi equal to seasoned sea lettuce, respectively. The order for eating frequency was stir-fried dried anchovies, braised peppers and dried anchovies, salted perilla leaf, and perilla leaf kimchi, respectively. Salted perilla leaf, perilla leaf kimchi, braised crab preserved in soy sauce, salted bean leaves, seasoned dried radish, and seasoned crab were either occasionally or frequently purchased by over 40% of the women. However, the reasons they did not purchase these products included: the excess use of chemical seasonings, unsanitary, unreliable cooking process, unreliable the origin, and high price, in the respective order. If the commercialized traditional basic side dishes were improved to eliminate these problems, 52.2% of the housewives would buy the products, and 65.6% anticipated increasing their use of these products in the future.

This study was evaluated mass production processes for flour noodles containing perilla leaf (FNPL) and to examine the antioxidant properties of FNPL. The processes for perilla leaf preparation before dough making were the main focus. The sensory evaluation was used as a tool to determine the optimal conditions for each step in the process. The appearance, taste, flavor, texture and overall acceptability were evaluated using a 9 point scale sensory evaluation. Eight minutes blanching of perilla leaf in boiling water (1:30, w/v) was found to be a suitable time to remove the unpleasant leaf flavor remaining in the final noodle product when fresh perilla leaf was used. The appearance, taste, texture and overall acceptability of FNPL were significantly different from FNPLs prepared with other blanching times. The appearance of FNPL containing 40% (w/v) perilla leaf homogenates was the best. In the dough making process, additional water was not required when 6 portions of 40% perilla leaf homogenate were added to 10 portions of flour, suggesting that the water adding step in the dough preparation process can be skipped. The antioxidant activity of FNPL was expressed as the radical scavenging activity. The DPPH ($IC_{50}$; 0.56 mg/mL), super oxide radical ($IC_{50}$; 9.53 mg/mL) and hydroxy radical scavenging activities ($IC_{50}$; 169.2 ${\mu}g$/mL) of FNPL were increased 19.6 (p<0.001), 1.4 (p<0.01) and 17.8 fold, respectively, compared to those for flour noodle (p<0.001). In conclusion, perilla leaf added to noodles at a final concentration of 19% (w/w) can increase the sensory and antioxidant properties of flour noodles.

A survey of the notion and intake on Kimchi among college women in Pusan was conducted to get some basic information on kimchi. Two hundred sixty seven students in Pusan participated in this survey. Seventy five percent of students answered that they like kimchi. They preferred well-fermented kimchi with anchovy extracts, refreshing taste and crispy texture the saltly and sweet. Chinese cabbage kimchi (87.6%) was found to be the most favored kimchi and Kakdugi(seasoned pickles of cubed radish), Nabak kimchi and Chonggak kimchi (ponytail kimchi) were followed in the order. The most favorite food made from kimchi was stir fried kimchi with rice. They disliked traditional special kimchi, such as Puchu kimchi (leek kimchi), Pa kimchi (green onion kimchi), Kkennip kimchi (perilla leaf kimchi), Godulbaegi kimch (Korea wild lettuce kimchi) and Gat kimchi (Leaf mustard kimchi). About 93 grams of kimchi was consumed daily and this amount was a little. Seventy percent of students did not have any experiences preparing kimchi. Experiences of kimchi preparation were given by mother through kimchii-making event for the winter(71.7%), cooking practice in middle or high school (14.1%) and college(10.9%) and general cooking education (33%). They preferred to buy kimchi at the Agricultural Cooperative Association (48.5%) or a large kimch factory (32.75). College students believe that kimchi is a healthy food and are willing to learn how to make kimchi.

Overproduction and accumulation of melanin in the skin will darken the skin and cause skin disorders. So far, components that can inhibit tyrosinase, a melanin synthase of melanocytes, have been developed and used as ingredients of cosmetics or pharmaceutical products. However, most of existing substances can only inhibit the biosynthesis of melanin while melanin that is already synthesized and deposited is not directly decomposed. Thus, their effects in decreasing melanin concentration in the skin are weak. To overcome the limitation of existing therapeutic agents, we started to develop a substance that could directly biodegrade melanin. We screened traditional fermented food microorganisms for their abilities to direct biodegrade melanin. As a result, we found that a kimchi-derived Pediococcus acidilactici PMC48 had a direct melanin-degrading effect. This PMC48 strain is a new strain, different from P. acidilactici strains reported so far. It not only directly degrades melanin, but also has tyrosinase-inhibiting effect. It has a direct melanin-decomposition effect. It exceeds existing melanin synthesis-inhibiting technology. It is expected to be of high value as a raw material for melanin degradation drugs and cosmetics.

The aim of this study was to investigate the quality characteristics of Kimchi, prepared with seasoning fluid, vinegar, and mustard extract to inhibit the proliferation of microorganisms and extend the edible period during fermentation at $25^{\circ}C$. We also added perilla leaf, endive, and mustard leaf to Kimchi to improve the flavor. The pH of control Kimchi fluid over 1 day after Kimchi processing, was $5.40{\pm}0.01$ and that of the experimental groups in which vinegar and mustard extract were added was $4.51{\pm}0.01{\sim}4.52{\pm}0.01$, which was lower than that of the control. As the fermentation progresses, the pH of the control decreased rapidly and that of the experimental groups decreased slowly. The initial titratible acidity of the control was low and 3 days later reached $0.95{\pm}0.04$. However, that of the experimental groups was $0.42{\pm}0.01{\sim}0.43{\pm}0.02$ and 5 days later reached a level similar to that of the control. The salinities of the Kimchi juice of both the control and the experimental groups were $2.67{\pm}0.06{\sim}2.80{\pm}0.10$% after 1 day and decreased during fermentation. The amount of lactic acid bacteria of the control was $8.17{\pm}4.01{\times}10^8cfu/g$, 1 day after the Kimchi processing and that of the experimental groups was $2.70{\pm}2.08{\times}10^7{\sim}3.63{\pm}2.80{\times}10^7cfu/g$. After 3 days, these were $3.13{\pm}1.94{\times}10^{11}cfu/g$ and $2.47{\pm}2.23{\times}10^9{\sim}8.03{\pm}3.71{\times}10^9cfu/g$, respectively. According to the result of sensory evaluation, throughout the entire period of the experiment, all sensory items such as color, odor, taste, texture, and total acceptability of the experimental groups were better than those of the control group (p<0.05). Especially, Kimchi in which perilla leaf was added was the best. With the addition of vinegar and mustard extract to the Kimchi, microorganism proliferation was inhibited and the edible period was extended. The minerals, vitamins and antioxidants of leaf vegetables could therefore be obtained.
