  • Three different fermentation methods of dongchimi, a Korean radish roots pickle, were compared with conventional method of brining in 7% NaCl solution at $25^{\circ}C$ in order to improve the storage stability. The methods studied were addition of KCI and $CaCl_2 into the hot ($90^{\circ}C$) salt solutin (method A), addition of salts mixture of phosphates (method B) and salts mixture of phosphates, nitrite and citrate (method C) into half fermented dongchimi solution (pH 4.5~4.7) prepared by the method A. It was found from results that the method B and C reduced the decreasing rate of pH very significantly by more than 2~2.5 folds, while total a measured higher values for the method B and C. Changes in hardness of dongchimi showed little diffeence to control. The concentration of reducing sugar in the first day dongchimi solution prepared by hot brining method was measured much higher than those of control which was followed by rapid decrease. Organoleptic comparion showed a clear effect of salts mixtures by receiving the significantly higher scores in fresh dongchimi flavor and lower values in yeast moldy and sour flavor for the method B and C when those were compared to control.

  • The removal amount of pesticide residue which were remained in baechu (Chinese cabbage) and perilla leaf were measured during the preparation process of kimchi. The amounts of diazinon, procymidone and endosulfan applied to chinese cabbage were $9.18{\pm}0.03$mg/kg, $22.27{\pm}0.22$ and $10.46{\pm}0.02$ mg/kg respectively. When chinese cabbage was brined with 10% salt solution for 12 hours, the removal rates of three pesticides were 22.5%, 25.3% and 0.6% for diazinon, procymidone and endosulfan, respectively. When chinese cabbage was brined and rinsed 3 times with water, the removal rates of three pesticides were 69.9%, 85.6% and 11.2% for diazinon, procymidone and endosulfan, respectively. When kimchi was prepared and fermented for 28 days at $4^{\circ}C$, the removal rates of three pesticides were 79.4%, 94.4% and 21.0% for diazinon, procymidone and endosulfan, respectively. The relative percentages of removal dose of pesticides during brining were 28.4%, 26.9% and 3.2% for diazinon, procymidone and endosulfan, respectively and which were 59.7%, 63.8% and 50.4% during rinsing and which were 11.9%, 9.3% and 46.4% during fermentation, respectively. The amounts of diazinon, procymidone and endosulfan applied to perilla leaf were $18.11{\pm}0.62$ mg/kg, $31.80{\pm}0.33$ and $12.01{\pm}0.01$ mg/kg, respectively. When perilla leaf was rinsed 3 times with water, the removal rates of three pesticides were 60.5%, 52.0% and 23.7% for diazinon, procymidone and endosulfan, respectively. When perilla leaf was rinsed and brined with 10% salt solution for 14 days, the removal rates of three pesticides were 93.9%, 92.4% and 49.6% for diazinon, procymidone and endosulfan, respectively. The relative percentages of removal dose of pesticides during rinsing were 64.5%, 56.3% and 47.8% for diazinon, procymidone and endosulfan, respectively, and which during brining were 35.5%, 43.7% and 52.2% for diazinon, procymidone and endosulfan, respectively.

  • 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.
