The coagulation of Chinese cabbage juice can be accomplished by applying the combine method of the formic acid with rate of 3% and in four hours the propionic acid with rate of 1 % in the juice. The separation of coagulation into the protein paste and the brown juice completed in 6.5 hours by set up method in special storage. The protein paste can be stored safely for 30 days in anaerobic condition.

Antibacterial activities of Chinese cabbage kimchi juice were determined against Staphylococcus aureus ATCC 6538p, Salmonella enteritidis ATCC 13076, Vibrio parahaemolyticus ATCC 17802 and Enterobater cloacae ATCC 13047. It was found out that 2% content of Chinese cabbage kimchi juice reduced the colony numbers of Salmonella enteritidis ATCC 13076, Enterobater cloacae ATCC 13047, Staphylococcus aureus ATCC 6538p and Vibrio parahemolyticus ATCC 17802 by 63%, 72%, 76% and 90%, respectively. 6% content of Chinese cabbage kimchi Juice completly inactivated Vibrio parahaemolyticus. But at the same content (6%) of Chinese cabbage kimchi juice, colony number of Salmonella enteritidis ATCC 13076 Enterobater cloacae ATCC 13047 and Staphylococcus aureus ATCC 6538p were reduced to 11%, 10% & 9%, respectively.10% Chinese cabbage kimchi juice had 100% inhibitory effect on all test bacteria. Therefore, Chinese cabbage kimchi has effective antibacterial activities against Staphylococcus aureus ATCC 6538p, Salmonella enteritidis ATCC 13076 Vibrio parahaemolyticus ATCC 17802 and Enterobacter cloacae ATCC 13047.

The fractionation of green juice could be one of the ways to treat the green juice for saving the bio re-sources by using the basic processes of protein coagulation and separating juice coagulation into protein paste and brown juice and storing the final products. The fractionation of Chinese cabbage juice can be accomplished by applying the combine method of the formic acid with rate of 0.3% and the propionic acid with rate of 0.1 % added 4 hours later in the juice with maximum recovery of protein coagulation. The separation of coagulation into the protein paste and the brown juice completed in 6.5 hours by set up method in a special designed storage. The protein paste could be stored safely for 30days in anaerobic condition.

The effective fermentation methods of Kimchi juice for utilization of outer layer of Chinese cabbage, an waste of Kimchi industry were studied. The Kimchi juice prepared with brining and grinding the waste of Chinese cabbage and addition of spices was fermented at $25^{\circ}C$. Addition of 5$^{\circ}C$15% fermented Kimchi juice of pH 5.4 at initial stage and pH 4.4 at middle state resulted in a significant increase in fermentation rate and solid content after 12 hours of fermentation. The combined method of enzymatic hydrolysis(0.1% viscozyme) of the brined and ground cabbage and addition of 2.0% NaCl, 1.0% sucrose and 10% fermented juice of pH 5.4 first and 4.4 during fermentation, respectively resulted in more rapid fermentation. The solid concentration was 5 times higher than control at maximum point and acidic and total flavor intensity were also significantly high.

The possibility of using Chinese cabbage juice as a substrate for the production of Candida utilis cell mass was explored. Dry cell weight production and cell yield coefficient were 1.35-1.45 g/100 ml undiluted juice and 47-50%, respectively, when C. utilis was grown by shake flask culture at $30^{\circ}C$ for 24 hr on more than three-fold diluted Chinese cabbage juice to make the final sugar content be equal to or less than 1.0%. Supplementation of glucose(2%), $KH_2PO_4(0.2%)$ and $(NH_4)_2SO_4(0.2%)$ to three-fold diluted Chinese cabbage juice did not enhance the dry cell weight yield or the protein content of the yeast cell, while supplementation of yeast extract(0.2%) and peptone(0.2%) increased dry cell weight production and protein content but not as much as the amount of each nutrient added. It was found that Chinese cabbage juice was an excellent substrate for the cultivation of C. utilis.

This study investigated the effects of Chinese cabbage powder as a natural replacement for sodium nitrite on the qualities of alternatively cured pork products. Chinese cabbages grown in Korea were collected and used for preparing hot air dried powder. Different levels of Chinese cabbage powder were added to pork products and evaluated by comparing these products to those with sodium nitrite or a commercially available celery juice powder. The experimental groups included control (100 ppm sodium nitrite added), treatment 1 (0.15% Chinese cabbage powder added), treatment 2 (0.25% Chinese cabbage powder added), treatment 3 (0.35% Chinese cabbage powder added), and treatment 4 (0.4% celery juice powder added). The cooking yields and pH values of treatments 1 to 3 were significantly lower (p<0.05) than the control. However, all of the alternatively cured products were redder (higher CIE a* values; p<0.05) than the control and this result was supported from higher nitrosyl hemochrome, total pigment, and curing efficiency. Furthermore, the inclusion of vegetable powders to these products resulted in considerably less residual nitrite content. However, Chinese cabbage powder (0.25% and 0.35%) was effective in producing alternatively cured meat products with a higher curing efficiency comparable to those of the traditionally cured control or the products with celery juice powder. Therefore, Chinese cabbage powder exhibited the efficacy for use as a natural replacer for alternatively cured meat products.

A possibility of utilizing Chinese cabbage, a kind of renewable resources which is frequently overproduced in Korea, for the production of single cell protein was investigated. Saccharomyces cerevisiae and Candida utilis grew well in cabbage juice producing 4.3 and 5.1 g/l of dried yeast cells, respectively. Freezing fresh cabbage prior to juice extraction did not affect the growth of yeasts and the final cell yield.

The aim of this study is to elevate the efficiency of salting with low salt concentration in order to improve the quality of salted Chinese cabbage. The efficiency of salting was tested with various sub-atmosphere(760mmHg to 0mmHg), temperature(20$^{\circ}C$ and 30$^{\circ}C$), and concentration of salt(3%, 5% and 10%). The salting efficiency was estimated by amounts of juice, calcium elution, sodium penetration and the state of tissue. The amunts of juice eleuted from Chinese cabbage was increased significantly with the decrease of atmosphere and the time to reach the highest amounts was reduced. This tendency was promoted, with increase of salinigy(from 3% to 10%)and the increase of temperature(more juice at 30$^{\circ}C$ than 20$^{\circ}C$). The amounts of eluted calcium from Chinese cabbage tissue during salting under sub-atmosphere was directly proportional to amounts of juice and was inversely proportional to penetrated sodium. The salting time was reduced with elevation of sub-atmosphere. It was desirable to take between 5.5 and 9 hours to salt under the condition of 3% of salting, 20$^{\circ}C$, and 560-0mmHg. It took between 4.4 and 5 hours under 5% of salt and between 4 and 4.5 hours under 10% of salt. However, it was undesirable because the drying phenomenon and the transparency of tissue appeared under 30$^{\circ}C$ and 160-0mmHg.

Addition of sugar, enzymatic hydrolysis and salt concentration were evaluated for their effects on the changes in some characteristics of Kimchi juice during fermentation. The Kimchi juice was prepared by brining and grinding of outer layer leaves of chinese cabbage, one of the wastes products of Kimchi processing, followed by fermentation proceeded significantly faster. Addition of sucrose or glucose at the ange of 0.5~2.0 % also improved the fermentation but the concentration effect was little. Enzymatic hydrolysis on the brined cabbage prior to fermentation with a commercial polysaccharides hydrolases also increased the fermentation. However the solid concentration in Kimchi juice was rather decreased by higher concentration of NaCl and enzymatic hydrolysis. The reducing sugar content showed a rapid decrease from 24 hours of fermentation and the effect of enzymatic hydrolysis was little.

To establish tile standard condition of uniformed Kimchi product, we introduced the concept of starter and studied the preparation of rapid-fermented Kimchi. Of the strains isolated from Kimchi, Kakdugi and infant's feces, M7 strain grew effectively on aseptic Chinese cabbage juice and on salted Chinese cabbage, the growth of M7 was decreased severely. Inoculated with M7 in salted Chinese cabbage, appropriate range of pH and lactic acid content were reached at 8-13 hrs and 12 hrs after addition of spices, respectively. The result of sensory evaluation was not significant at 5% level.
