우육(牛肉) 지방질의 산화에 미치는 간장의 항산화작용(抗酸化作用)을 살펴보기 위하여 GCM(ground and cooked meat), GCM-water, GCM-brine, GCM-soybean sauce system들을 $6^{\circ}C$에서 5주간 저장하면서 TBA 값, 과산화물값, 지방산 조성 및 관능검사를 행하였다. 저장 기간 중 TBA값 및 과산화물값의 경우 GCM-soybean sauce system에서는 거의 변화가 없이 낮았으나 기타 system에서는 현저한 증가 현상이 있었으며 특히 GCM-brine system에서 심하였다. 각 system들의 지방산 조성에서는 모노엔지방산 및 폴리엔 지방산의 함량이 변화하였으며, 저장 후 중성지방질 획분에서는 리놀레산이, 또한 인지방질 획분에서는 아라키돈산의 함량이 상대적으로 감소하여 저장 중 산패가 상당히 진행됨을 알 수 있었다. 그러나 GCM-soybean sauce system에서 가장 그 변화가 적었다. 그리고 관능검사에서 나타난 변패취는 GCM-water 및 GCM system에서 2주 후에 각각 나타났으며 5주후에는 system 모두에서 나타났으나 GCM-soybean Sauce System에서 가장 낮은 변패취 생성 결과를 보였다. 그러므로 이와 같은 결과들을 종합해 볼 때 간장은 우육(牛肉) 지방질의 산화 억제 효과가 현저한 것으로 판단되었다.

There were three trials involved in this experiment. All piglets in Trial 1 were randomly distributed into the following 4 treatments. Treatment 1. Corn-soybean diet with 5% SDPP. The tryptophan level was 0.237%. Treatment 2. Corn-soybean diet with 10% meat and bone meal. The tryptophan level was 0.177%. Treatment 3. Treatment 1+0.0662% synthetic tryptophan. The total tryptophan level was 0.303. Treatment 4. Treatment 2+0.0662% synthetic tryptophan. The total tryptophan level was 0.236. Piglets in Trial 2 were distributed randomly into the following 4 treatments. Treatment 1: corn-soybean diet+10% meat and bone meal. The total tryptophan level was 0.176%. Treatment 2: corn-soybean diet+10% meat and bone meal+5% SDPP. The total tryptophan level was 0.180%. Treatment 3: Treatment 1 diet+0.004% synthetic tryptophan. The total tryptophan level was 0.180%. Treatment 4: Treatment 1 diet+0.631% synthetic tryptophan. The total tryptophan level was 0.237%. There were 4 treatments in Trial 3. Treatment 1: cornsoybean diet+10% meat and bone meal. The total tryptophan level was 0.176%. Treatment 2: Treatment 1 diet+0.061% synthetic tryptophan. The total tryptophan level was 0.237%. Treatment 3: Treatment 2 diet+0.061% synthetic tryptophan. The total tryptophan level was 0.298%. Treatment 4: corn-soybean diet+10% meat and bone meal+5% SDPP. The total tryptophan level was 0.180%. The results of Trial 1 showed that the piglets ate significantly more (p<0.05) when feed included SDPP in the diet during the first 2 weeks. The feed intake also increased when synthetic tryptophan was added in the 5% meat and bone meal diet; however, the difference did not reach a significant level (p>0.05) during the first 2 weeks. Three weeks onwards the feed intake of 5% meat and bone meal treatment was significantly lower (p<0.05) than for the other three treatments. The results of Trial 2 showed that the feed intake could be significantly improved only when the total tryptophan level reached 0.237%. Piglets in the 5% SDPP treatment had higher feed intake than piglets in 10% meat and bone meal treatment with 0.180% of tryptophan, but did not reach a significant level (p<0.05). Body weight gain also had the same trend as feed intake. The pigs in Treatment 1, the lowest total level of tryptophan treatment (0.176%), had lowest feed intake and weight gain, but the difference did not reach a significant level (p>0.05). The pigs in Treatment 1 of Trial 3 had the lowest feed intake and weight gain (p>0.05). Treatment 2 (0.237%) had the highest average feed intake from Week 1 to Week 5; the second best result was recorded in Treatment 4. As for the weight gain of the piglets in Treatment 4 (5% SDPP), they had a higher average weight during the first 3 weeks. The feed efficiency was better for Treatment 4 (5% SDPP) during the first 2 weeks. The results of these trials showed that both SDPP and tryptophan had a trend to improve the feed intake and weight gain.

Physicochemical properties and storage stability of plant-based alternative meat prepared with low-fat soybean powder (LPAM) treated by supercritical-CO₂ and those of full-fat soybean powder (FPAM) were compared. Ash and crude protein contents were higher in LPAM than in FRAM. Water absorption capacity and oil absorption capacity were significantly higher in LPAM than in FPAM. Water binding capacity was higher in LPAM than in FPAM during a 20 days storage period at 5℃ and pH was significantly lower in LPAM than in FPAM after a 5~10 days storage period. Hardness, gumminess and chewiness significantly increased with the increase in the storage period, and the three were significantly higher in LPAM than in FPAM after 10 days and 20 days of storage. The acid value showed no remarkable difference according to the storage period in LPAM; however, it was significantly higher in FPAM than in LPAM after 20 days of storage. The peroxide value and TBA value were significantly increased according to the storage period, and were significantly lower iin LPAM than in FPAM during all the storage periods. Therefore, the use of low-fat soybean powder may be effective in improving oxidative stability during storage in the production of plant-based alternative meat.

Two experiments were conducted to evaluate the use of fish silage prepared from Indian oil sardines, Sardinella longiceps, as partial replacement of soybean meal as a sole source of protein for growing broiler chickens. The main objective of Experiment 1, an ileal digestibility assay, was to assess the nutritional value of fish silage compared with soybean meal for feeding broiler chickens. The two test ingredients, soybean meal and dried fish silage, were incorporated into semi-synthetic diets, as the only component containing protein. The ileal digestibility coefficients of amino acids of fish silage were considerably higher than those of soybean meal (p<0.001). The lower digestibility of amino acids from soybean meal was related to the presence of anti-nutritional factors such as trypsin inhibitors. Fish silage had higher levels of sulphur-containing amino acids than soybean meal. The objective of Experiment 2, a growth study, was to evaluate the effect of feeding fish silage on performance and meat quality characteristics of broiler chickens raised under closed and open-sided housing systems. Four diets containing various levels of fish silage (0, 10, 20 and 30%) were evaluated. Daily feed intake, body weight gain and feed conversion ratio were measured. At the end of Experiment 2, 96 birds were randomly selected and slaughtered to evaluate meat quality characteristics. Housing type had significant effects on feed intake and body weight gain (p<0.01). Birds in the open-sided house consumed 4.7% less amount of feed and gained 10.6% less than their counterparts in a closed house. Birds in both houses fed diets containing 10 and 20% fish silage gained more than birds fed 30% fish silage. The current study produced evidence that fish silage can replace up to 20% of soybean meal in broiler diets without affecting either growth performance or the sensory quality of broiler meat.

Objective: The current study aimed to replace soybean oil in broiler diets with linseed oil, which is rich in omega-3 fatty acid supplemented with pomegranate peel extract (PPE) and measured its effect on broiler performance, carcass traits, lipid profile, as well as fatty acids composition, phenols and flavonoids content of broiler muscles and immunity of broiler chicks. Methods: A total of 300 1-day-old Cobb chicks were randomly allotted into six experimental groups, T1 fed on basal diet with soybean oil without any additives, T2 fed on basal diet with soybean oil with addition of 0.5 g/kg diet PPE, T3 fed on fed on basal diet with soybean oil with addition of 1 g/kg diet PPE, T4 fed on basal diet with linseed oil without any additives, T5 fed on basal diet with linseed oil with addition of 0.5 g/kg diet PPE and T6 fed on basal diet with linseed oil with addition of 1 g/kg diet PPE. The PPE supplementation with 0.05% improved final body weight with either soybean oil ration or linseed oil ration. Results: The PPE improved carcass dressing percentage in comparison with the control groups. Body fat levels decreased with increasing PPE levels, especially with a linseed oil diet. Replacing soybean oil with linseed oil decreased the total cholesterol and triacylglycerol levels in broiler serum. The PPE supplementation decreased serum total cholesterol levels and increased high-density lipoprotein cholesterol levels. The content of the breast muscle alpha linolenic acid improved after replacement of soybean oil with linseed oil in broiler diets. PPE supplementation increased the phenol and flavonoid content in broiler meat and increased lysozyme activity. Conclusion: Replacing soybean oil with linseed oil in broiler diets with the addition of PPE enriched muscle meat with omega-3 fatty acids and antioxidants and improved broiler immunity and their serum lipid profile.

Flounder were fed a reference diet and test diets containing various feed ingredients: mackerel fish meal, meat meal, soybean meal, wheat flour, wheat gluten, corn gluten meal and brewer's yeast. Apparent digestibility was determined using a reference diet with 0.5% chromic oxide indicator and test diets contained 70% reference diet and 30% of the feed ingredient being evaluated. Apparent digestibility coefficients for amino acid and energy in the reference and test diets were determined, and digestibility coefficients for the test ingredients were calculated based on differences in the digestibility of test diets relative to the reference diet. The fish averaging 300 g were held in 2000 L tanks at a density of 20 fish per tank. Feces were collected from three replicate groups of fish using a fecal collection column attached to fish rearing tank. Apparent total amino acids digestibilities(90-95%) of mackerel fish meal, soybean meal, wheat gluten, corn gluten meal and brewer's yeast were higher than those of meat meal and wheat flour(P<0.05). Apparent energy digestibilities(86-98%) of mackerel fish meal, meat meal, soybean meal, wheat gluten and corn gluten meal were significantly higher(P<0.05) than those of wheat flour and brewer's yeast. These results provide useful information about nutrient and energy utilization for flounder.

The origines of the Western roasting culture and East Asian boiling culture were studied and the importance of primitive pottery culture (8000-5000 BCE) in the Korea Strait coastal region was discussed. The primitive pottery culture probably initiated the Jjigae (stew) culture and the production of salt. It can be also postulated that fish fermentation, kimchi fermentation, and cereal alcohol fermentation originated during this period. Soybean culture emerged ca. 2,000 BCE in South Manchuria and the Korean Peninsula. This paper focuses on the role of Korean foodways in the food science and technology development for the sustainable and resilient food systems. We are facing a global food crisis caused by population growth, climate change, and high animal food consumption. Studies on the meat analog and cultured meat are the new trend in Food Science and Technology. The importance of the wisdom learned through the Northeast Asian traditional foods, for example, soybean curd (tofu) and meaty flavor production by fermentation for the research on the novel sustainable and resilient food systems are discussed.
