Imitation milk는 식물성유(soy milk)에 식물성유(油), 탄수화물, whey powder, Nacascinate, 필수아미노산, 비타민, 무기물 등을 배합 가공한 것이다. Spray dried 방법으로 제조한 imitation milk의 feed efficiency ratio 및 영양가 측정은 Albino Rat의 사육시험과 화학적분석 방법으로 측정하였다. 지방산과 아미노산의 각 성분조성은 Gaschromatography 및 Amino Acid Autoanalyzer로 분석하였다. 이 연구 결과를 고찰하여 보면 필수아미노산과 고도불포화지방산이 feed efficiency ratio에 큰 영향을 미친것을 확인할 수 있다.

Biofertilizers are increasingly available in the market as one of the alternatives to chemical fertilizers. The supply of a high number of viable microorganisms is important for farmers. Lysobacter capsici YS1215 producing chitinases and gelatinases, isolated from soil in Korea, was evaluated for the establishment of an optimal medium condition of its shelf life under an in vitro condition. In this study, the population density of a biofertilizer (L. capsici YS1215) in media containing crab shell and gelatin powder (M1, M2, M3 and M4) was observed to be higher than that of populations grown in TSB (Tryptic soy broth) media (M5, M6 and M7) during experimental period. In addition, the population density at 11 months was over $10^6\;CFU\;mL^{-1}$ in M1, M3 and M4, but under $10^6\;CFU\;mL^{-1}$ in M2, M5, M6 and M7. The best optimal medium for the shelf life was M1 ($2.6{\times}10^6\;CFU\;mL^{-1}$) containing both chitinous and gelatinous materials at 11 months. Therefore, this study provided results of the appropriate medium composition for the enhancement of the shelf life of L. capsici YS1215.

The purpose of this paper is to survey various recipes of the roasted beef with twenty three classical cookboods written before 1943. The roasted beefis found total 32 times in the literature which can be classified into seven groups such as the roasted rib, roasted foot, roasted tail, roasted heart, roasted gall, roasted kidney and roasted fresh meat. The most frequent one is the roasted rib appearing eight times and the next is the roasted sliced beef with seasoning appearing seven. This proves that the those recipes have been the most favorite ones to Korean people for a long time. The roasted rib has been found since the middle of the 17th century, but the process of roasting ribs again with seasoning after three successions of dipping shortly into cold water in the midst of roast wasz disappeared. The roasted sliced beef with seasoning originated since the late 18th century, and the roasted beef with salt since the early 19th century which has been inherited as the roasted raw upper part of roasted beef recipes have been continued until today in the similar manner. Generally the roasted meat with bones and the roasted internal organs started in 1766 earlier than the roasted fresh meat by a century. The main ingredients were rib, foot, tail, heart, gall, kidney, fresh meat and knee bone, and the seasonings were mixtures of scallion stalk, garlic, pepper, oil, soy sauce and sesame seed powder. And peculiarly salted shrimp, pear juice, ginger were added to seasonings and pine nut powder was used as decorating ingredient.

The Hen's egg is widely used in many processed foods as an ingredient and is one of the most prevalent food allergens in children. To detect egg proteins in processed foods, we developed a competitive indirect enzyme-linked immunosorbent assay (ciELISA) using an anti-ovomucoid (OM) antibody, which was produced by immunization of rabbits with OM, the most heat-stable component of the egg proteins. The detection limit of this quantitative assay system was 30 ng/mL. Cross-reactivity of the anti-OM antibody toward OM, ovalbumin, skim milk, casein, whey protein isolate, and isolated soy protein was 100, 0.4, 0.2, 0.04, 0, and 0%, respectively. In the spike test of egg white powder in milk replacer, commercial sausage, and in-house sausage, the assay recoveries ($mean{\pm}SD$) were $129{\pm}13.7%$, $73.9{\pm}12.5%$, and $65.5{\pm}13.6%$, respectively. When egg white in a commercial crab meat analog and sausage was determined by ciELISA, the assay recovery was found to be 108% and 127%, respectively. The combined results of this study indicate that this novel ciELISA for OM detection could be applied for the quantification of hen's egg proteins in processed foods.

Various peptides derived from food are among the most potent physiologically active agents known, and include anticancer peptides, angiotensin converting enzyme(ACE) inhibitor exhibiting antihypertension action, opioid peptides, antithrombotic peptides, hypocholesterolemic peptides, immunomodulators, calcium absorption enhancers, and other peptides. Hydrophobic peptides extracted from a Cheddar-type cheese slurry were fractionated by gel chromatography and repeated HPLC. A peptide fraction from HPLC showed high cytotoxicity on the tumor cell lines such as a human colon carcinoma, and comprised of Tyr, Ser, Leu, Gly, and others. Hypocholesterolemic peptides were isolated from peptic hydrolyzates of casein and soy proteins. Macropeptides of 1,000${\sim}$5,000 dalton were effective on reducing the cholesterol level of mouse serum. Peptides showing high Krigbaum hydrophobicity and ANS surface hydrophobicity resulted in high hypocholesterolemic effect and fecal steroid concentrations. Caseinomacropeptides(CMP) were isolated from whey powder and treated with soluble and immobilized trypsin to obtain antithrombotic peptides. One fraction from the CMP hydrolyzed with immobilized trypsin for 24h exhibited high antithrombotic activity with 52.5% inhibition of platelet aggregation. These result suggested that peptides from various milk products could be utilized as a good bioactive agents for developing health functional foods.

This study was carried out to investigate the effect of high pressure and the addition of non-meat proteins on the physico-chemical and binding properties of restructured pork. Pressurizations were carried out at up to 200 MPa and non-meat proteins used as a binder were isolated soy protein (ISP), sodium caseinate (SC), whey protein concentrate (WPC) and egg white powder (EWP). The pH values of all treatments were affected by the level of pressure. $L^*$-value of all treatments increased significantly (p<0.05), while both $a^*$-value and $b^*$-value of all treatments showed a significant decrease (p<0.05) with increasing pressure level. Binders could contribute only additive effects on both pH and color of the treatments. It was found that high pressure improved the water binding capacities and binding strength of the treatments. Binders also improved the binding strength of restructured pork. However, SC and WPC had no effect on water binding properties under high pressure. These results indicate that the application of high pressure had more significant effect on restructuring meat than binders.

The purpose of this study was to develop the standardized recipe and to analyze the nutrients of stir-fried whip-arm octopus as one of the kind of traditional local foods in Busan. The standardized recipe was developed by using cookbooks, home recipes, and the recipes by commercial food restaurants. The nutrient was analyzed by using an AOAC method. Sensory evaluations were made on nine sensory attributes by a 12-member panel. As the results, the whip-arm octopus was recorded as a food source for health, rejuvenation in Jasanobo. Since early 1900, the stir-fried method has been used for cooking with the ship-arm octopus. The main ingredients were whip-arm octopus, onion, large green onion as the local stir-fried whip-arm octopus in Busan. The ingredients of soup were shrimp, little neck clam, and water. Seasoning sauce was mixed with red pepper powder, soy sauce, sesame oil, chopped garlic, chopped onion, and sugar. The seasoning sauce was fermented for three days. The results of sensory scores were salty seasoning 3.66/5.00, taste 3.75/5.00, thickness 3.84/5.00, and smell 4.09. Nutrient retention per 100g of the stir-fried whip-arm octopus was 67.54kcal, protein 6.43g, fat 1.66g, Ca 28.06mg, Fe 2.56mg, cholesterol 68mg, and taurin 51mg. Fatty acid consists of various unsaturated fatty acids such as linoleic acid(46.24%) and oleic acid(33.67%).

고추장, 고춧가루, 과채열수추출액 첨가에 의한 돼지불고 기양념육의 항산화 증진 효과와 혼합물 실험설계법을 이용한 돼지불고기용 양념소스 재료의 최적 혼합 비율을 확립하고자 하였다. 냉동저장($-25^{\circ}C$, 5개월) 동안 간장양념을 사용한 대조구와 고추장양념첨가구(KG), 고추장양념.과채열수 추출액첨가구(KFVEG)의 TBA가는 저장기간 동안 원료육에 비해 모든 돼지불고기 양념육에서 낮게 유지되었다. 양념육 중에서는 대조구보다 고추장양념첨가구의 항산화력이 크게 우수하였으며, 고추장양념첨가구의 물 사용량을 과채 열수추출액으로 대체함으로써 항산화 상승작용이 유의적으로 나타났다. 따라서 양념소스에 고추장, 고춧가루, 과채열 수추출액 첨가로 돼지불고기양념육의 지방산화 안정성이 증진되었다. 양념육의 기호성은 고추장과 함께 사용된 고춧가루와 과채열수추출액 사용 비율이 증가함에 따라 향상되는 것으로 나타났다. 혼합물 실험 설계법에 의하여 추적된 돼지불고기용 고추장양념소스의 최적 혼합 비율은 고추장 0.04, 고춧가루 0.20, 과채열수추출액 0.39, 물 0.37로 나타났다.
