The purpose of this paper is to examine the various kinds of recipes of pheasant through classical cookbooks written from 1670 to 1943 which are the basic materials to the meat cooking. The recipes of pheasant are found 39 times in the literature, which can be classified into eleven groups. Chronologically, the recipe of mandu (ravioli) was first appeared, and guk, tang (soup), kui (roasted), jang (salted meat), chim (steamed), po (dried meat), whe (raw meat), gijim (boiled in soy sauce), cho (sparkly heated in soy sauce and sugar), jolim (hard boiled in soy sauce), and jungol (meat with vegetable cooked in pan) followed in the records. Kui was the most popular one with the frequency of 43.6%, which proves that kui is the most suitable one for pheasant among all of recipes. Mandu and guk, tang were 10.2%, chim and po were found with the same rate of 7.7% and the next ones were jang, gijim, cho, and jungol with the rate of 2.6%. The recipes of pheasant were recorded much less than those of beef, chicken, pork, lamb, and dog meat. Particularly, in comparison with chicken belonging to fowls, the frequency of pheasant cooking did not reach even to one third of that. The Korean recipes of pheasant have been independently developed with originality, having nothing to do with the Chinese ones. The recipes of pheasant before the late 1800s have based on the strict recipe principles along with the spirit of art and sincerity, but they were deteriorated to simple and easy ones discarding principles. The main ingredient was the flesh of pheasant and the sub-ingredients such as flour, pinenut, buckwheat powder, and mushroom were included in common. In additon, oil, soy sauce, black pepper, and stone leek were frequently used as main seasonings.

A supplemental effect of Undaria Pinnatifida extract on the composite flour prepared from a blend of wheat, barley, sweet potato, potato, and defatted soybean flours was studied in terms of binding properties, cooking test, and sensory analysis. Dry noodle of the composite flour was made by the conventional method and air dried. Instant noodle was prepared in a hot vegetable oil bath after the noodle was made. The standard was made of wheat flour only. 1. The noodle prepared with composite flour (wheat flour : barley flour, 5 : 5) and Undaria Pinnatifida extract (1 or 2%) showed same results of cooking and sensory tests as well as properties of texture as the standard. 2. The mixture of wheat, barley and defatted soybean flour (10%) had a less efficient binding capacity with Undaria Pinnatifida extract. The binding effect was, however, significantly improved with the wheat and barley flour mixture with either sweet potato or potato flour. 3. The instant noodle prepared with the composite flour (either barley, or sweet potato, or potato was mixed with wheat flour up to 70% separately) and hydroxypropyl methyl cellulose (1% as final) showed the higher oil absorption and the sensory results were the same as the standard. Nevertheless, the binding properties and cooking quality were less efficient.

More than 500 different compounds have been identified in the cooking process of frying oil as a result of chemical reactions such as oxidation, polymerization, hydrolysis and pyrolysis, 3-MCPDe(3-Monochloropropane -1,2-diol ester) and GE(glycidyl ester) are also included in these compounds. When MCPDe and GE derivatives are absorbed into the body, they are converted into free forms by lipase enzymes, which turn into 3-MCPD and glycidol(2,3-epoxy-1-propanol), respectively. These exhibit genotoxic and carcinogenic effects. As the toxicity of 3-MCPDe and GE is known worldwide, the health risk is being researched. However, regulations have not been established in countries other than the European Union(EU). Several studies for the analysis of 3-MCPDe and GE are being conducted, and direct methods and indirect methods are applied. As a result of analyzing 3-MCPDe and GE contained in commercially available foods by various analysis methods, the content of 3-MCPDe in baby food/infant formula was ND~600 ㎍/mL and GE was ND~750 ㎍/mL. and purified vegetable oils and fats showed <250-8,430 ㎍/mL and 1,880-9,530 ㎍/mL. Thus, 3-MCPDe and GE were detected in various food types, several studies for the reduction of 3-MCPDe and GE are being conducted around the world.

Korea supposed the place of origin of soybean. Although it is speculated that it was edible in the era of the Three Kingdoms(A.D. 5-9C), there is no documentary evidence. The first record about the edibility of tofu was written down in the Goryeo dynasty, and there was several documents that tofu was exported to China and Japan in the Chosun dynasty due to excellent manufacture skills for tofu. Tofu has been a good source of protein as a food for the common people, though there were not many traditional kinds. Especially, tofu has been an important vegetarian foodstuff in a Buddist temple, and has been used for vegetable soup and skewered greens necessary for the sacrificial rites of the humbler class as well as of the royal court. We frequently made sliced raw tofu and fried tofu, and it was used for broil, stew, and casserole as well as stuffing. In addition, tofu and its bean-curd dregs were applied of making soy. In China it is assumed that tofu has been eatable since the time of the Han(AD. 1C). Chinese tofu and its products are various and generally 20 different varieties are used. There are many dishes applied of tofu. salted and plain tofu were used as Chinese appetizer dishes. Plain, salted, skinned or deep-fried tofu was stir-fried in an hot oiled pan with vegetables, meats and fishes. Additionally, there are a variety of tofu dishes utilized stewing, frying, steaming, and soup cookeries. Tofu first appeared in the era of the Nara(8C) of Japan and was come into wide use in the era of the Aedo(Tokyo). In Japan tofu and its products are various and introduced in Shojin cookeries prevalent in the Buddist temples. It is especially noticeable that frozen or skinned tofu was used for these. Japanese tofu cooking is more delicate than Korean and Chinese ones, and Japanese people do not use oil. Instead, they in general utilize steaming and broiling cookeries. In the western countries the history of tofu edibility is short. However, their practical application of tofu in the dietary life is very positive.

Biochemical and functional properties of acid-soluble collagen (ASC) and pepsin-soluble collagen (PSC) from rockfish skin were characterized. Yield of PSC (90.0%) was higher than that of ASC (63.2%). Both ASC and the PSC consisted of ${\alpha}1$ and ${\alpha}2$ chains, and $\alpha$-cross-linked components. According to the results of hydroxylation of proline and lysine, and FT-IR, no difference between the helical structure of ASC and PSC was identified. Thermal denaturation temperature (TDT) of ASC from rockfish skin was $22.8^{\circ}C$, the same as exhibited in PSC. Both ASC and PSC were higher in water absorption capacity (WAC) and oil absorption capacity (OAC) than other vegetable proteins. According to the results of emulsifying activity (EA) and cooking stability (CS), both ASC and PSC from rockfish skin were inferior compared to the commercial emulsifier (Tween-80). The results of FT-IR suggested that the structure of PSC was slightly different when compared to that of ASC. No differences in solubility were established between ASC and PSC from rockfish skin at various pH and NaCl concentrations.

This study was made for male and female university students regarding the nutrition knowledge about fat, fat contents in food, and practice toward fat. The result is as follows;1.Out of 13 questions inquiring the knowledge about fat a significant difference was observed between female and male students in 10 questions. Male students' nutrition knowledge about fat was $6.33{\pm}0.16$, and that of female students' was $6.33{\pm}0.16$ and there was no significant difference. The ratio of correct answer was 49% and 59% respectively. Female students marked high ratio of correct answer such items as ${\omega}-3$ fatty acid, the relation between high fat diet and atherosclerosis(coronary disease), the relation between obesity and fat, the relation between ${\omega}-3$ fatty acid and heart disease, cholesterol, fatty acid in butter, degree of unsaturation in liquid oil, margarine, chicken fat, rancity of fat. 2.Male students' total score of knowledge about fat quantity in food was $4.91{\pm}0.10$ and that of female students was $5.58{\pm}0.10$. There was significant difference(p<0.001) and the ratio of correct answer was 55% and 62% respectively. Out of 9 food items, significant difference was observed in 7 items according to student's majoring subject. The ratio of correct answer for the questions about the quantity of fat in food female showed high figures in such items as white meat(p<0.01), whole milk(p<0.0001), skim milk(p<0.01), potato chips(p<0.001), biscuit(p<0.001). However, male students showed high figures on the question about the quantity of fat in vegetable margarine. 3. Out of 12 items observing the degree of diet practice on fat, significant difference was observed between male and female students in 6 items. Female students practice the question items positively with high ratio: intake of fish instead of meat(p<0.01), removing visible fat in meat(p<0.0001), removing chicken skin(p<0.0001), removing oil during cooking (p<0.05), selection of low fat milk or skim milk(p<0.05), selection of meat part(p<0.001). There was significant difference between male and female students in practicing diet on fat (p<0.001) and the total score was $31.52{\pm}0.52$ and $34.65{\pm}0.41$ respectively.

The compositions of saturated and unsaturated fatty acids in biodiesel feedstocks are important factors for biodiesel properties including low-temperature fluidity and oxidative stability. This study was conducted to improve low-temperature fluidity of biodiesel by reducing total saturated FAME (fatty acid methyl ester) in animal fat biodiesel fuels via urea-based fractionation and by mixing plant biodiesel fuels (rapeseed-FAME, waste cooking oil-FAME, soybean-FAME, and camellia-FAME) with enriched-polyunsaturated FAME derived from animal fat biodiesel. Our results showed that the reduction of total saturated FAME in animal fat biodiesel lowered CFPP (Cold Filter Plugging Point) to $-15^{\circ}C$. Mixing plant biodiesel fuels with the enriched-polyunsaturated FAME derived from animal fat biodiesel lowered CFPP of blended biodiesel fuels to $-10{\sim}-18^{\circ}C$.
