Journal of the Korean Society of Food Culture, volume 7, issue 4, 1992, Pages 291~296
The effects of steeping time of glutinous rice and of beating time of the cooked rice on characteristics of Ganjung was examined. and the optimum conditions of traditional Gangjung preparation were determined. Moisture absorption of glutinous rice was the maximum at 2 hours of steeping in water and did not increase much after then. pH of the steep water was the lowest at 7 days of steeping and increased slightly thereafter. Reducing sugar content of the steep water increased as the steepting time was extended. Expansion ratio of Gangiung was the greatest with 5 days of steepting, and tended to decrease with longer beating time. Optimum conditions of Gangjung preparation was 7 days of steeping glutinous rice and 4 minutes of beating (40 times/min) the cooked rice.

To investigate effects of the surface finishing methods (A : conventional press stone, B : enclosing in polyethylene (PE) bag, C : press-tone wrapped with PE film and D : covered with Chinese cabbage leaves 4cm in thickness on Kimchi) on Kimchi quality, pH-values, redness, film forming yeast growth, hardness and sensory quality of Kimchi during storage (for 60 days, at
) in glass vessel
were investigated. pH of the top layer of A, C and D sample were higher than the optimum pH (4.2) of Kimchi, film forming yeast occurred on the surface of Kimchi, color of top layer Kimchi juice was darkened, and panel score of freshness and firmness was significantly worse (p<0.01) than that of sample B. However, in the case of Kimchi stored in PE bag (B), film forming yeast were can't detected visually in the surface of Kimchi, pH values were low as good quality Kimchi, freshness and firmness panel scores and hardness were significantly better (p<0.01) than A, C and D, and redness of juice of top layer of B was also preserved clearly for 60 days. Accordingly among the four surface finishing methods, the B-method was most effective in preserving of y of Kimchi.

Journal of the Korean Society of Food Culture, volume 7, issue 4, 1992, Pages 303~307
The lipid compositions of buckwheats produced in Korea were analyzed. The samples used in this experiment were as follows; Kyungbuk rice buckwheat. Kangwon hull buckwheat and Kangwon rice buckwheat. The total lipids were extracted and fractionated to neutral lipids, glycolipids and phospholipids respectively by silicic acid column chromatography (SACC). As a result, neutral lipids content of these three samples were in the range of 82.77-95.65%; glycolipids in 1.97-10.83%; and phospholipids in 2.21-6.40%. The composition of neutral lipids of these three samples showed that triglyceride were in the range of 88.7-92.0%; monoglyceride in 2.3-4.0%; free fatty acid in 3.0-3.7%; diglyceride in 0.7-0.8%.; free sterol in 0-0.7%; and steryl esters in 0-2.2%. The major fatty acids of total lipid, neutral lipid, glycolipids and phospholipids of these three samples were oleic, linoleic and palmitic acids.

A study was designed to assess the current status of infant feeding and weaning practice through an retrospective survey on feeding method, a period of weaning and various kinds of weaning food. Analysing a few influential environmental factors while assessing the level of knowledge today's mothers have on infant nutrition. The results are as follows: 1. As random samples for this study, a total of 516 mothers having infants under the age of 3 were surveyed. Among them, 235 were from Seoul and 281 were from Kyongi province (Yongin, Suwon, Bupyong, Poil, Kihung, Ansan(Chungbuk)). 2. Among the infants who fell under the category of normality (Kaup index
), the infants from Seoul area amounted to 60.7%, surpassing the percentage of the infants from Kyongi province, 41.9%. The percentage of the infants belong to a group of under nutrition (Kaup index <13) was relatively higher than that of the infants in a group of overnutrition (Kaup index >20). 3. 16.1% of mother surveyed were breast-fed, 54.6% were formula-fed and 29.3% were mixed-fed. The result indicated that the percentage of breast-fed infants of high-educated, working mothers were relatively lower than those of low-educated housewives. 4. Most of the respondents knew the significance or the necessity of supplementary food in terms of weaning. 5. 98.8% of those surveyed responded that the mother's adequate knowledge on weaning was necessary. 70.1% of them replied that they wanted to get various and in-depth information in printed materials such as books or other kinds of publications. They, also showed deep interest in recipe of weaning food. 6. The average period when those surveyed began weaning of their infants was
months. The tendency of earlier weaning in 3 months was founded among 41.1% of them. About half of the respondents, 52.3%, started weaning of their infants in
months. In overall, 93.4% of them set on weaning in less than 6 months after babies were born. The survey, in addition, revealed an interesting fact that earlier weaning of infants was shown in the group of high-educated mothers. 7. According to the study, finishing period of weaning was
months on average. Only 38.9% of the respondents ended weaning of their infants in 12 months, the proper period recommended by renowned experts. In general, the infants on formula-feeding finished their weaning later than those on breast-feeding (p<0.05).

Three kinds of soy sauce were prepared using the brick type of conventional meju (A), the brick type of meju of Aspergillus oryzae (B), and the grain type of meju of Aspergillus oryzae (C) in summer. Free amino acids were analyzed in according to aging time of those products. Findings are as follows. Lysine, histidine, serine, glycine, valine, methionine, and phenylalanine were detected in all kinds of soy sauce at the beginning preparation. Aspertic acid, glutamic acid, alanine, threonine, arginine, and leucine were detected during 90 days. Isoleucine and tyrosine were detected during 180 days. Lysine and histidine were shown higher content among the detected free amino acids. The each content of glutamic acid, aspartic acid, and methionine was decreased in passing the aging time. The total content of free amino acids was shown 3,559-4,119 mg/100 ml at the 180 days. The total content of free amino acids of soy sauce C was higher than that of other soy sauces.

This study was attempted aimed to prepare of Andong sikhe by pure culture inoculation and to improve storage stability by the addition of stabilizers to the product. Lactobacillus delbreuckii was selected for pure culture inoculation in the fermentation. The effect of stabilizers on the sedimentation, sensory evaluation and viscosity of Sikhe were investigated during the fermentation of traditional Andong Sikhe stored at
Morphological characteristics of Sikhe were determined by scanning electromicrograpy. Among the stabilizers added to the traditional Andong sikhe Na-alginate was found to be best stabilizers. When the product was evaluated by the sensory panel, the addition of stabilizers up to 0.1% level actually increased the acceptability of the product, while the concentration of more than 0.2% stabilizers affected the acceptability of the negatively. Sikhe added Na-carboxymethyl cellulose and Na-alginate showed highest viscosity on the 2nd day of fermentation, while homogenized Andong sikhe with Carrageenan showed the highest peak in viscosity on the first day of fermentation. Lactic acid bacterial count reached to
after 20 days of storage. The surface and cross section of rice was observed by scanning electron microscope. As the fermentation proceeded holes on the surface increased, and nearly empty cell wall remained at the later stage of fermentation. Use of pure cultured inoculum of L. delbreuckii supported the rapid build up of the lactic acid bacteria and consequently the whole process of the fermentation was shortened. The acceptability and product quality were improved by use of L. delbreuckii inoculum.

The Guk was divided Malgunjangguk, Tojangguk, and Gooumguk as to cooking method. Gooumguk was boiled with several materials of beef, bone, organs and water for the long time, and a good source of protein, calcium, and phosphorus. In the thesis, according to the kinds of Gooumguk, the reference frequency to them, the adding foods in them, and the variety cooking method in the Gooumguk were analyzed by the cooking books published from 1670 to 1988 in Korea. 1. There were 41 kinds of Gooumguk and Kaejang, Joktang and Byultang were firstly published to Omshikdimibang in 1670. 2. Many kinds of Gooumguk were generally used on royal parties in Yi dynasty and were used by several substances. 3. The main substances of Gooumguk were meat, poultry, fish, and shellfish. The seasoning substances were green onion, garlic, ginger and black pepper etc, and were used for the removal of the meat's or fish's off-flavor. 4. Yangtang, Kalbitang, Joktang, Yeongebacksuk, and Chooatang etc expressed the taste of the one main substance and Japtang, Sulnongtang, Yukgejang, Yongbongtang etc were combinated the taste of the several materials. 5. Cooking methods of Yukgaejang and Koritang before 19 century were different in present.: Yukgaejang was not used Gochoojang or powdered red pepper and Koritang was used Gochoojang.
