This study examined the changes of side dishes in "Eumsikdimibang", "Gyuhapchongseo", "Chosunmusangsinsikyorijebub" over time. As food ingredients, seaweed, red pepper, salted fish, Korean hot pepper paste have been used in "Gyuhapchongseo". The use of cattle by parts, saltwater fish, Chinese cabbage, powdered red pepper, garlic have increased in"Chosunmusangsinsikyorijebub". Cooking techniques, such as the use of wheat flour, a double boiler by the use of steam, and boiling and then roasting cuisine were mostly used in"Eumsikdimibang", but reduced in"Gyuhapchongseo". In "Gyuhapchongseo", the cooking methods are primarily aimed at a positive visual effect, and slices of dried meat seasoned with spices have increased. In"Chosunmusangsinsikyorijebub", various Tang (Guk), the taste of food changed by controlling the gravy content (Gigimi, Chigye, Chorim), meat mixing oil, vegetable and mushroom together to cook and boiling down the main food ingredients to soak the seasoning were increased. Dog-meat steamed dish using the intestine of dog in "Eumsikdimibang" was changed to small intestine of cattle steamed dish in "Gyuhapchongseo". And seasoned dog meat with choncho in "Eumsikdimibang" influenced on beef tail soup with Korean hot pepper paste in "Gyuhapchongseo", and Yookgyejang soup using Korean hot pepper paste in"Chosunmusangsinsikyorijebub". In steamed young chicken, the stuffing such as soybean paste, choncho, welsh onion, leek and flour in "Eumsikdimibang" was changed to minced beef, welsh onion, dropwort and Shiitake mushroom in"Gyuhapchongseo". The steamed young chicken in "Chosunmusangsinsikyorijebub" with stuffing was added to chicken soup using glutinous rice, and ginseng powder. Now, the chicken soup was changed to Samgyetang with glutinous rice, and ginseng. In "Chosunmusangsinsikyorijebub", various vegetable dishes were cooked with beef.

The number of elderly in care facilities is increasing in parallel with a rapid increase in the elderly population in Korea. We analyzed the meal satisfaction ratings, food preferences, and nutritional intakes of 74 patients aged ≥65 years living in a nursing hospital in Daegu. Food preferences were high for cooked rice, rice gruel, meat soup, soybean paste stew, beef, frozen pollack, squid, egg, spinach, sea mustard, cabbage kimchi, apple, peanut, drinking yogurt, pickled perilla leaves, and salted squid. Preferences for duck (P<0.01) and vegetable (P<0.01) cooking method were significantly different for men and women, and preference for soybean paste stew increased with age (P<0.05). Regarding nutrient intakes, men had higher energy (P<0.01), carbohydrates (P<0.05), and zinc (P<0.05) intakes than women, while women had higher vitamin C (P<0.05) intake than men. Furthermore, energy (P<0.001), carbohydrates (P<0.001), protein (P<0.05), dietary fiber (P<0.01), vitamin B₆ (P<0.01), phosphorus (P<0.05), and zinc (P<0.001) intakes significantly decreased with age. Men had a significantly higher nutrient adequacy ratios (NARs) for carbohydrates (P<0.05) and cal- cium (P<0.01) than women, while women had a significantly higher NARs for protein (P<0.05), vitamin A (P<0.01), vitamin C (P<0.05), thiamine (P<0.01), riboflavin (P<0.001), iron (P<0.001), and zinc (P<0.01). Mean adequacy ratios were 0.69 for men and 0.75 for women. In particular, NARs for carbohydrates (P<0.01), vitamin B₆ (P<0.01), and calcium (P<0.05) decreased significantly with age. In summary, the study shows that supplementing vitamin C, vitamin B₆, calcium, and iron, reducing sodium, and providing meals that reflect preferences will improve the nutritional statuses of elderly residents in a nursing hospital.

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.

Nitrate and nitrite, which readily produce N-nitrosamines by reaction with secondary amines, are widely distributed in natural products such as vegetables and cereals, and are also used as a color fixation in meat products or fish roes. This experiment was carried out to determine the contents of nitrate and nitrite in foods such as fermented sea foods and fresh vegetables purchased at markets in Korea. The contents of nitrate were $0.74\sim13.81\;ppm$ for fermented sea foods and $4.0\sim1,572.5\;ppm$for fresh vegetables. As for vegetables, the nitrate levels of edible herbs were relatively higher than those of greens, fruits and rootcrops. The nitrite contents in fermented demoisells(Chromis notatus), fermented shrimp, fermented small squid, fermented anchovy and salted Alaska pollack roe were very little, while those in fermented hairtail and fermented entrails were not detected. As for vegetables, nitrite levels found for cabbage and lettuce were relatively as high as 3.8 ppm and $2.5\sim2.9\;ppm$, respectively, but were not detected in Korean cabbage, green perilla leaf, pepper, garlic and burdock. Of vegetables, the nitrate values in the outer part of Korean cabbage, stems of water cress and leaves of green onion were higher than in the other parts. Little variety of the nitrate levels were found during 4 days storage. In the comparison of low temperature storage and room temperature storage, lettuce, pumpkin and spinach contained higher levels of nitrate at low temperature storage, while eggplant and green onion, at room temperature storage.

The nutrient composition, including the proximate composition and the mineral, vitamin, amino acid, and free-amino-acid levels, of baechu kimchi (Chinese cabbage kimchi) to which 14 kinds of seafood (flatfish, yellow corvina, sea beam, pollack gizzard shad, ray, gray mullet, skate, hairtail, anchovy, sea squit, pen shell, scallop, small octopus)were added was analyzed. The seafoods were added to salted cabbage at concentration of 10% (w/w) and the prepared seafood baechu Kimchi (BK) was stored at $5^{\circ}C$ for seven days. The levels of moisture (82.09-88.56%), crude lipid (0.31-0.64%), and crude ash (2.70-3.50%) did not differ much among the samples, but the level of crude protein of the BK-with-seafood samples (2.42-5.15%) was greater than that of the control BK (2%), without seafood. The Fe and Ca contents of BK with flatfish showed the highest values (4.1 and 74 mg/100 g, respectively). The vitamin A contents of BK samples with 14 different kinds of seafood were higher than that of the control BK. Moreover, the BK with sea squit had higher vitamin $B_2$ (0.90 mg/100 g) and vitamin C (8.48 mg/100 g) contents among all the BK-with-different-kinds-of-seafood samples. Total amino acids were detected in all BK-with-seafood samples, most of which had high levels of glutamic acid, aspartic acid, proline and alanine. Glutamic acid was the most abundant of all the amino acids. The major free amino acids were hydroxyproline, glutamic acid, alanine, proline, leucine, and valine, of which hydroxyproline was the most abundant. In conclusion, BK with seafood is thought to be a very good source of protein, which is very important from dietary life of humans.

This study was conducted to investigate the quality characteristics of kimchi with Allium hookeri powder (AHP) added during eight weeks fermentation at $4^{\circ}C$. AHP was added to salted cabbage at concentrations of 0, 0.1, 1, and 5% (w/w). The quality characteristics of the AHR-added kimchi were determined by measuring pH, acidity, salinity, reducing sugar, microbial amounts, and sensory properties. The vitamin $B_1$ and vitamin C contents of the Allium hookeri root were 0.04 mg/100 g and 5.76 mg/100 g, respectively. As for the mineral contents, the K content was highest, followed by the Ca, Mg, and Fe contents. The pH was higher in the kimchi with 0.1%, 1%, and 5% AHP than in the kimchi without AHP during the eight-week fermentation. The salinity ranged from 2.02% to 2.37% over the eight weeks. The microbial cells and lactobacilli increased rapidly throughout the fermentation in the exponential phase and hardly increased in the stationary phase. In the sensory evaluations, the overall acceptance, taste, and texture of the kimchi with 1% AHP added were highest. In conclusion, the kimchi with 0.1%, 1%, and 5% AHP generally showed better quality than the kimchi without AHP. Especially, the kimchi with 1% AHP had the best scores in quality and overall acceptance during the fermentation.

The effects of green tea powder (GTP) on kimchi quality were evaluated by investigating acid production, growth of lactic acid bacteria, sensory properties, and several volatile odor components of GTP-added kimchi. The concentrations of GTE added to kimchi were 0.2, 0.4, 0.6 and 1.2% (w/w) of salted Chinese cabbage. The pH of kimchi with higher amounts of added GTP increased with ripening. The acidity of unripened kimchi or kimchi ripened for one day generally increased with the addition of GTP, while that of kimchi ripened for two or three days generally decreased with the addition of GTP. Addition of GTP had no significant effect on the lactic acid bacterial count of kimchi. Scores of overall acceptability, taste and odor of 0.2 or 0.4% GTP-added kimchi were higher than those of other samples, whereas scores of color decreased with increasing amount of GTP added to kimchi. Texture of kimchi added with higher amounts of GTP and ripened for two or three days resulted in lower score than the reference sample. Diallyl sulfide and methyl trisulfide were newly produced with the ripening of kimchi, and the amounts of some volatile odor components in kimchi were changed during ripening.

This study investigated the antioxidant properties of yangha(Zingiber mioga Rosc) and quality characteristics of kimchi with added yangha during a 21-day fermentation process at $4^{\circ}C$. Yangha was added to salted cabbage at concentrations of 0, 5, 10, and 15% (w/w). The quality characteristics of kimchi with added yangha were determined by measuring pH, salinity, mineral contents, lactic acid bacteria amounts, color value and sensory evaluation. From the results, total phenolic ($3.85{\mu}M$ quercetin equivalent/g) and total flavonoids ($0.49{\mu}M$ quercetin equivalent/g) contents were measured in yangha. The number of lactic acid bacteria of kimchi with added yangha significantly increased with increasing yangha content, especially 10%. The brightness value increased with increasing yangha content. However, the redness tended to decrease by the addition of 10% and 15% yangha. The consumer acceptability score for the kimchi with added 10% yangha ranked significantly higher than that of the other groups in overall acceptability, taste, flavor, and color(p<0.05). From these results, we suggest that yangha may be used as a natural antioxidant and that it is a good food ingredient for increasing the functionality and consumer acceptability of kimchi.

The study of quality and salting characteristics of root vegetables other than Chinese cabbage was done to develop different kinds of Kimchi. The root vegetables lotus (Nelumbo nucifera) and lance Asia bell (Codonopsis lanceolata) were evaluated as main ingredients for Kimchi by measuring their physico-chemical and microbial properties. Salinity, pH, titratable acidity, reducing sugar, firmness, color change, moisture content, total viable counts, and lactic acid bacteria were investigated to identify adaptability for Kimchi. The initial pH of lotus and lance Asia bell showed 5.7 to 6.3 during the salting period, and the pH decreased with increasing salting periods. The reducing sugar contents of lance Asia bell showed 34.1 to 35.6 mg/g, which were significantly higher compared to lotus 3.2 to 3.4 mg/g. Titratable acidity also showed higher in salted lance Asia bell at 0.36 to 0.4%, while lotus showed 0.17 to 0.27%. Lactic acid producing bacteria increased in lance Asia bell during salting periods and reached $2.1{\times}10^4CFU/g$ after 48 hr of salting. However, no lactic acid bacteria were detected in lotus. As a result of this physico-chemical and microbial analysis, lance Asia bell was more suitable as an ingredient of Kimchi than lotus.

Calcium-enriched powder was investigated for use as an ingredient in kimchi formulation to retard the fermentation rate and to fortify the nutritional quality of kimchi. The calcium powder was added to salted Chinese cabbage in the concentrations of 0.5, 1.0 and 1.5%, and then stored at 10$\^{C}$. Quality characteristics of kimchi such as pH, titratable acidity, reducing sugar content and microbial loads were measured during fermentation. After a lag period of 2 days, pH and reducing sugar abruptly decreased until 10 days, and then attained to stabilized levels, while acidity increased steadily for 20 days. Addition of calcium powder with 1.5% retarded the change rates of pH and acidity, showing the slowest chance and the highest final pH. Kimchi added with calcium powder maintained a higher reducing sugar content during the whole fermentation period of 25 days. Kimchi samples which were added with 0.5% and 1.0% of calcium powder and fermented at 10$\^{C}$ for 7 days showed better sensory scores in aroma and taste than the other samples.
