We examined the quality characteristics and texture of Jokpyuns with chicken and codfish. In proportion to the increase of water addition, the color became lighter and the texture characteristics decreased in So-Jokpyuns, which were prepared with cow feet. The texture and taste had an influence on overall preference of So-Jokpyun. Yongbon-Jokpyun which was prepared with cow feet and chicken was much preferred to So-Jokpyun in the appearance and texture, and showed a similar preference with So-Jokpyun. However, Sodaegu-Jokpyun which was prepared with cow feet and codfish was not preferred to So-Jokpyun in all items including appearance and texture, and the overall preference was remarkably low. Overall preference of Yongbong-Jokpyun and Sodaegu-Jokpyun was greatly related with the preference of taste and flavor. The lightness and the degree of yellow color of Yongbong-Jokpyun were higher and the degree of red color was lower than So-Jokpyun. On the other hand, the results of lightness, degree of red and yellow color in Sodaegu-Jokpyun were opposite to those of Yonsbong-Jokpyun. In case of the hardness, Yongbong-Jokpyun was the lowest and Sodaegu-Jokpyun was similar with So-Jokpyun. Adhesiveness of Yongbong-Jokpyun and Sodaesu-Jokryun was lower than that of So-Jokpyun. There was no difference in the springiness and cohesiveness among 3 kinds of Jokpyun.

This study investigated the nutritional components of jokpyun. Jokpyuns made with cow feet and two kinds of jokpyun were added 30% of chicken and dry codfish to 70% of cow feet, respectively. There was no difference in moisture contents among three jokpyuns. Crude protein content was higher in jokpyun made with cow feet than in those added chicken and dry codfish. Contents of lipid and ash in jokpyuns added chicken and dry codfish were higher than those of jokpyun made with cow feet. The ratio of unsaturated fatty acid in jokpyun added dry codfish was the highest, but, that of linoleic acid was the highest in jokpyun added chicken than the others. Amino acid contents were higher in the order of glycine, proline, alanine, glutamic acid and composition of essential amino acid was similar to soupstock made with beef shank and leg bone. The contents of glycine and alanine in jokpyun added codfish and that of glutamic acid in jokpyun made with cow feet were the highest. Especially, among essential amino acids lysine was the highest in all jokpyuns. Methionine and valine were higher jokpyun added chicken and jokpyun made with cow feet than the others. Calcium and phosphorous were higher in jokpyun added chicken than in others. From these results, jokpyun, especially added chicken, was seemed to be more nutritious than other jokpyuns.

This study was conducted to examine the effects of levels of flavoring materials on the sensory characteristics of chicken feet Jokpyun (Korean traditional gel type food) and to determine the optimum levels. Consumer desirability of Jokpyun flavored with different levels of black pepper and ginger was evaluated. Optimum levels of variables were obtained using response surface methodology. The levels were 0.33% and 0.1% for black pepper and ginger extract, respectively. The shelf-life of the optimized Jokpyun at $4^{\circ}C$ was determined as 6 days. Addition of powdered chicken broth in the Jokpyun preparation at the level of 1.5%(w/w) markedly increased boiled chicken flavor without resulting in undesirable properties.

The present study was conducted to survey the daily and speciality meals consumed by middle-aged residents of Gang-hwa. The data were analyzed by determining the frequencies at which daily and specialty meals were consumed with respect to the quantitative and qualitative data. The subjects mainly consumed Japgok-bap 28.6%, kong-bap 25.0%, ssal-bap 20.5%. The daily meals consumed included juk, 3 kinds; guksu 11 kinds; mandu, 2 kinds; tang and malgeon-guk, 37 kinds; doenjang-guk, 10 kinds; goum-guk, 13 kinds: naeng-buk, 4 kinds; jjigae, 23 kinds; jjim, 12 kinds; gui, 29 kinds; jeon 22 kinds; jijim, 3 kinds; namul, 33 kinds; saengchae, 6 kinds; japchae, 1 kind; jorim, 29 kinds; sun, 1 kind; bokkeum, 7 kinds; hoe, 2 kinds; ssam, 4 kinds; muchim, 5 kinds; jaban, 1 kind; jokpyun pyunyuk, 1 kind; bugak, 14 kinds; twigim, 1 kind; and muk, 4 kinds. The subjects prepared jangachi(272, 81%), jeot-gal (143, 42.6%), dried food (75, 24.4%), storage food (116, 36.1%), liquor (54, 16.1%), and tteok(162,48.2%) in their homes. There were 62 kinds of speciality food and 75 kinds of food inherited foods from the subject's mother or passed down from the husband's mother to daughter or daughter-in-law in Ganghwa. Therefore, we need to preserve and develop our traditional foods and our traditional cooking methods far our future generations.

In this study kinds of Lamb cooking and preservation and the ingredients of lamb cooking are surveyed through the references written from 1670 to 1943. The lamb cooking found in the literature totaled to more than 53. They can be classified into fourteen different groups according to their processing features which as follows: Salnum and Pyunyuk(boiled and slices of boiled), Kui(roasted), Chim(steamed), Whe(raw meat), Hounjae(smoking), Po(dried), Juk(gruel), Tang(soup), Sundae(stuffed small interstines), Jokpyun(jellied foot), Jungol(happiness pot), Sikhae(salt+meat+malt), Oumjang(salted meat), Kunjo(dried). Korean lamb cooking methods were primarily adopted from Mogolia in late Korea Dynasty but they had unique characteristics different from Mongolian ones. Furthermore, they were creatively applied to other meat cooking such as beef, pork and dog. About twenty one ingredients were mainly used in lamb cooking, including fresh meat, ribs, breast, heart, liver and the like. In particular, most popularly used ones were fresh meat and the heart in internal organs, which coincide with the main ingredients in beef cooking of today. The number of seasoning used in lamb cooking was twelve and especially salt, vineger, ginger and stone leek were most commonly used ones. Fourteen other addition were put into lamb cooking and the rice(Korean) wine was the most frequently used addition.
