  • Acid production and growth of lactic acid bacteria, sensory properties, volatile odor components, and effects of freeze-drying on quality of kimchi prepared with whole, midlib, and leaves of Chinese cabbages ripened at $20^{\circ}C$ for 3 days were investigated. Salinities of whole, midlib, and leaf were 2.31, 2.03, and 2.68%, respectively, In kimchi pH of midlib was the lowest and that of leaf was the highest, while acidities of whole and midlib were higher than that of leaf. Numbers of lactic acid bacteria in whole and midlib were slightly higher than that of leaf. Overall acceptability, taste, and odor of kimchi and freeze-dlied/rehydrated kimchi prepared with whole or midlib were better than those of leaf. Volatile odor components such as ethanol and sulfur-containing components of kimchi prepared with whole or midlib were generally higher than those of kimchi prepared with leaf.

  • This study was undertaken to examine the effect of salting in 10% salt solution added 2% calcium chloride on the kimchi fermentation. The addition of calcium chloride extended edible periods of the Kimchi to 4~5 days and increased relatively the hardness of Chinese Cabbage. In the addition of calcium chloride, the activities of amylase and $\beta$ -galactosidase were not high during all periods fermentation. Polygalacturonase and protease activities were low 2~21%, 2~26% all periods fermentation, respectively. There were significant correlations between the delay of ripeness and decreasing enzyme activation. The amount of free amino acid by the treatment with calcium chloride was decreased of 10~16% at the late of fermentation than that of control. the treatment with calcium chloride of the Kimchi was increased hardness, but decreased cohesiveness and gumminess was during all periods fermentation. the adhesiveness was increased at the early of fermentation but decreased at the late of fermentation.

  • The macro-and microstructure of Chinese cabbage used for Korean Kimchi preparation were examined and the texture characteristics of raw cabbage leaf and salted or blanched leaves were evaluated by cutting test. The length and thickness of leaf stalk increased with the order of pyllotaxis, but the thinning effect of outermost leaves was observed. The microstructure of cut-profile of stalk showed densely compacted vascular systems aligned in the center of stalk and the outer space was filled with large parenchima cells. Due to this structure, characteristic cutting curves were obtained by cutting test, composing three peaks of cutting for inner surface skin, center vascular system and outer surface skin. Salting and blanching increased the cutting force mainly due to the increase of Gutted cell wall number caused by the structure collapse.

  • The effects of yeast on the fermentation of kimchi were investigated. The treatments were divided into two groups; yeast treatment during salting of Chinese cabbage(YS) and yeast treatment added in kimchi preparation(YF kimchi). The edible periods of the kimchi after yeast treatment during salting (YS kimchi) was extended 4~5 days by the results of pH, acidity, sensory quality. The activities of amylase, polygalacturonase and galactosidase of YS kimchi were retained at low levels compared to non treated condition throughout all fermentation periods, whereas protease activity was not significant different from the non treated condition. In addition, the contents of total hexose and uronic acid did not show remarkable change throughout fermentation, but total pentose was decreased by more than 7% at the early middle stage of fermentation(7~14 day after soaking). The change of free amino acid content was decreased by 16~44% than the non treated condition. In contrast, in the YF kimchi, the sensory quality was not good. The activities of amylase, protease, polygalacturonase and gal actosidase were appreciably higher than that of the non treated condition. Meanwhile, the contents of total hexose, total pentose and uronic acid, as products of degradation of cell wall constituents by the above enzymes, were decreased by 18~68% throughout fermentation than the non treated con dition, and total free amino acids were higher than the YS kimchi. Thus, yeast treatment during salting was found to be more effective to extend the edible periods of the kimchi.

  • To elicit the effect of fermentation on food quality of the watery Chinese cabbage pickles without fish sauce and red pepper paste(Baik-kimchi), changes in physicochemical properties and microstructure of fiber components were studied. Better water holding capacity(WHC) was showed in Baik-kimchi fermented at $25^{\circ}C$ than that of Baik-kimchi fermented at 5$^{\circ}C$. WHC measured at pH 2 and 6 were ranged from 10.18 to 16.79g/g dried sample for Baik-kimchi fermented at $25^{\circ}C$ and 6.51~14.58g/g dried sample for sample for samples at 5$^{\circ}C$, respectively. The higher WHC was resulted in pH controlled freeze-dried sample to pH 6 than that measured in pH 2 sample. The settling volume(SV) and oil adsorption capacity(OAC) increased with fermentation period and kept the same value for a little while, but slightly decreased in the over ripening period. Baik-kimchi fermented at $25^{\circ}C$ exhibited more shrunk microstructure of parenchyma cell and xylem than those of Baik-kimchi fermented at 5$^{\circ}C$. The appearance of SDF of the both Baik-kimchi ripened at 5$^{\circ}C$ and $25^{\circ}C$ could give granular shape, whereas the overripened Baik-kimchi had smooth surface of SDF. On the other hand, the IDF retained the original shape during fermentation.

  • The diffusion phenomena of water, solid and reducing sugar in Chinese cabbage during salting (5$0^{\circ}C$, 25% salt solution) and desalting (5$0^{\circ}C$, distilled water) were investigated. Water loss and solid gain during salting were rapid in the first 6hrs and then almost leveled off. After 24hrs of salting, water loss and solid gain in 100g of initial wet Chinese cabbage were 33.35g and 6.26g respectively. Moisture content was changed from 94.29% to 83.11% during 24hrs of salting. The reducing sugar concentration was also changed from 29.2 mg/$m\ell$ to 6.5mg/$m\ell$, which was linearized as a function of the square root of salting time and showing that Y=30.1841-5.0269√t. After 24hrs salting, water gain and solid loss during desalting were rapid in the first 4hrs and then increased linearly. After 12hrs of desalting, the water gain and solid loss in 100g of initial wet Chinese cabbage were 20.82g and 9.14g respectively. The amount of solid loss after 12hrs desalting was higher than that of solid gain after 24hrs salting due to the diffusion of solute presented initially in the Chinese cabbage during salting and desalting. The concentration of salt in Chinese cabbage after 12hrs desalting was 2.98% which was a suitable salt concentration for the preparation of Kimchi. At this time, the concentration of reducing sugar was only 1.6mg/$m\ell$. The linear regression equation of reducing sugar concentration during desalting was Y=6.7854-1.5992√t.

  • Calcium powder from whey (WCF) was added to enrich the calcium content of kimchi, and the mixing ratios of it to salted Chinese cabbage were 0.5, 1.0 and 1.5%. Quality characteristics of kimchi such as pH, titratable acidity, reducing sugar content and microbial loads were measured during fermentation at 10$^{\circ}C$. Kimchi samples with WCF showed a higher level in pH and titratable acidity than that of control during fermentation. Kimchi having higher WCF maintained a higher in pH and titratable acidity, and titratable acidity was above 1.0% about 12 days in kimchi sample with 0.5% WCF. Reducing sugar content was steadily decrease after 5 days, and control maintained a higher than others. Microbial load was similar until 10 days, but control was lower than kimchi samples with WCF. Based on the titratable acidity, kimchi with WCF had a limitation in shelf life.

  • 1) In Seoul, it was known that the season for preparing Kimchies (fermented vegetables) for the winter was from the middle of November to early in December, in which the preparing rates of Kimchies in the middle of November, the end of November and early in December were 32.7%, 41.3% and 12.5%, respectively. The time that the largest quantity of them was prepared was about the end of November. 2) The average cost of Kimchies prepared for the winter for a family of four, five, six and seven was $10,000{\sim}15,000$ Won, $15,100{\sim}20,000$ Won, $10,100{\sim}20,000$ Won and $10,100{\sim}20,000$ Won, respectively, and the cost did not increase in proportion to members of a family. In case of the family of $6{\sim}7$, the cost for Kimchies showed a wide range compared with those for the family of $4{\sim}5$ 3) The main raw materials of kimchi for one person for the winter required $12{\sim}20$ heads of Chinese cabbages, $14{\sim}20$ roots of radishes, $4{\sim}7$ cloves of garlics and $300{\sim}500g$ of powdered red pepper. 4) The residents living in Seoul had prepared the several kinds of the pickles for the winter as follows; (1) Chinese cabbage Kimchi (98.9%), (2) Whole Chinese cabbage Kimchi (74.7%), (3) Kkakdugi (68.6%), (4) Dongchimi (66.4%) and (5) Chong-kak Kimchi (63.3%). It has, therefore. been considered that the five kinds of Kimchies mentioned above may be industrialized. 5) Uniqueness of the raw materials used for the most popular Chinese cabbage Kimchi was to use leeks, garlics, red peppers and gingers as spices, and it was also known that proper amounts of salted shrimp pickles and oysters was mixed to the Kimchies. Therefore, it had been considered that the characteristics of Chinese cabbage Kimchies for the winter had the hot taste with freshness. 6) For keeping the Kimchies during the winter about the half of the pickle jars was buried in the ground, and another half of them were wrapped in the straw bags or styropol and they were placed on the ground or kept in the basement, 7) In most case (80.9%), the salt concentration of pickling was adjusted by one's experiences, and only 19% of them was measured with the instruments. 8) Most of remaining kimchies were usually used for other cooks, but some of them were thrown away. 9) The ratio of the people who had ever bought the market Kimchies for their own edibility was 17.8% and most of them got it only in the spring and summer season. 10) About 18% of the residents living in the general houses in Seoul had ever bought the market Kimchies. It was also known that about 48% of the residents living in the general houses and about 79% of the residents living in the apartments wanted to purchase the market Kimchies if the production of the delicious Kimchies were industrialized. The season that the people wanted to get the market Kimchies was a little different each other among the residents. About 13.4% of the residents living in the general houses wanted to purchase the Kimchies during the summer, and 11.9% of them wanted to get it throughout the year. On the other hand, in case of the apartments, 25.2% of the residents wanted to get it during the summer and 24.4% of them wanted it throughout the year (4 seasons) and 19.9% of them wanted it during two seasons. The data mentioned above have shown that many residents hope strongly an industrial production of the Kimchies. It is also true that many residents living in both the general houses and apartments want to get the market kimchies throughout the year, and particulary during the summer season that most foods are very apt to be spoiled.
