  • This study was conducted to evaluate the optimal processing conditions of smoke-dried powdered oysters and to determine their shelf-life during storage for development of a natural oyster flavoring substance. The optimal conditions for processing of smoke-dried oyster powder with freshy oyster were as follows. Raw shelled oysters were rinsed with 3% saline solution, drained, boiled for 10 minutes at $98^{\circ}C$, and then smoked for 1 hour at $50^{\circ}C$, followed by drying for 4 hours at $80^{\circ}C$ Smoke-dried oyster powder with oyster scraps were prepared as flavoring material. The smoked oyster scraps were submerged in oyster sauce far 10 minutes at room temperature and then dried with hot air for 5 hours at $50^{\circ}C$. The smoke-dried oysters and smoke-dried oyster scraps were then pulverized to 50 mesh and packed in tea bags or vacuum-packed in laminated plastic film bags (PE/PVDC/CPP, $12{\mu}m/15{\mu}m/50{\mu}m$). Compared to non smoke-dried powdered oysters, the smoking and dipping in oyster sauce enhanced the flavor and prevented lipid oxidation of the smoke-dried powdered oyster product. Shelf-life tests indicated that the vacuum-packaging method preserved the quality of smoke-dried powdered oysters stored for 150 days at room temperature.

  • 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.

  • This experiment was carried out to determine the total dietary fiber content and free sugar, fatty acid, amino acid compositions in bamboo shoot, lotus root and burdock. Bamboo shoot contained 3.05% of proteins, 0.48% of lipids, 2.45% of fibers, which were larger than those of other samples (lotus root and burdock). Burdock contained more sugars than the others as 18.64%. On a dry matter basis, total dietary fiber by Prosky AOAC method were 62.5% for bamboo shoot, 17.9% for lotus root and 41.9% for burdock. Therefore, the content of dietary fiber in bamboo shoot was the most abundant among them. Free sugar contents (glucose, fructose and sucrose) of the sample were analyzed by HPLC. Sucrose was the most abundant in both bamboo shoot and lotus root, and the content of fructose and sucrose in burdock were almost same. The major fatty acids in bamboo shoot, lotus root and burdock analyzed by GC were palmitic and linoleic acid. Also, linolenic acid were abundent only in bamboo shoot. The results of amino acid analysis showed that aspartic acid, glutamic acid and Iysine were the most abundent amino acids in the sample. Bamboo shoot contained large percentage of protein, the sweet-tasting amino acids and lipid than the other samples. Therefore bamboo shoot can be used as a flavor material because they contain plenty of the sweet-lasting amino acid and free sugar. Bamboo shoot and burdock can be used as potential source of dietary fiber because of the high content of dietary fiber in those samples.

  • The substitution effects of whey protein isolate(WPI) for egg in the preparation of sponge cake were determined by objective and subjective tests. Milk whey is drained from milk curd as a by-product of cheese manufacture. Whey protein is known as a good nutritional source and a functional material for many processed foods, especially baked goods. WPI contains above 90% whey protein. The specific gravity and viscosity of sponge cakes tend to be affected by WPI substitution. The cooking loss of sponge cakes with WPI substituted for egg(abbreviated as WPI cake) during oven baking was smaller than that made with egg(abbreviated as egg cake) and the specific loaf volume of WPI cake was larger than that of egg cake. The number of pores was highly increased and the size of pores was more uniformly and finely distributed in the cross section of WPI cake than those of egg cake, as observed by scanning electron microscopy(SEM). The hardness, gumminess and chewiness of WPI cake made with 10-20% WPI substitution were the lowest among all the tested cakes, including egg cake, thereby confirming the considerable improvement in their cake qualities. By the results of sensory evaluation, appearance, pore uniformity, softness, chewiness, moistness, flavor, mouth feeling, and overall acceptability of 10-20% WPI substitute cakes were evaluated as being significantly superior to those of all other cakes(p<0.05). These results support the better physicochemical characteristics and sensory evaluations of sponge cake prepared with 10-20% of WPI substitution for egg.

  • Beer production with rice or other malt substitutes suffers from a lack of suitable enzymes for saccharification. For this reason, rice nuruk (fermentation starter) was tested as a starch replacement for malt in the saccharification process of beer production. The results of this study show that the enzyme activities of rice nuruk made with brewing fungi were higher than those of malt. Saccharification and glucoamylase activities were high in Aspergillus awamori KCCM 30790 and α-amylase activity was high in Aspergillus oryzae CF1003. Overall, malt beer had significantly higher alcohol, pH, total acid, volatile acids, amino acids, free amino nitrogen, bitterness unit and ΔE than rice nuruk beer. Where as Aspergillus awamori KCCM 30790 beer had significantly higher soluble solids, reducing sugar than malt beer. According to a sensory evaluation, malt beer was better color, flavor and Aspergillus oryzae CF1003 beer was better taste, texture, overall acceptability than other beer. Therefore Aspergillus awamori KCCM 30790 beer was suitable considering enzyme activities (saccharification, glucoalmylase) and physicochemical characteristics (soluble solids, reducing sugar). And then Aspergillus oryzae CF1003 beer was suitable considering sensory evaluation (taste, texture, overall acceptability). Therefore rice nuruk like Aspergillus awamori KCCM 30790 and Aspergillus oryzae CF1003 were suitable as a substitute material that can replace for malt in beer proceccing.

  • This study was conducted to ascertain the antioxidant properties of Hamcho (Salicornia herbacea L.) and as well as manufacture pettitoes using Hamcho as a natural antioxidant material for diverse applications. The DPPH radical scavenging activities of 25, 50, 100 mg/mL in methanol extracts from Salicornia herbacea L. increased significantly (p<0.05) to 12.8%, 21.6% and 39.1%, respectively. The total phenolic content was $38.58{\pm}4.25{\mu}M$ as tannic acid equivalent for 100 mg/mL of methanol extracts from Hamcho. FRAP value was $448.58{\pm}14.01{\mu}M$ as ascorbic acid equivalent in reducing power. To apply Hamcho to food as a natural antioxidant, pettitoes were prepared with added Hamcho. To manufacture pettitoes added with Hamcho, general quality characteristics of pettitoes added with 0%, 2%, 4% and 6% based on 100 g of pettitoes were determined. In conclusion, mineral components increased according to the added amount of Salicornia herbacea L. Crude protein showed the highest value with 2% added Hamcho. Overall, the addition of Hamcho led to hardening of the meat texture. As a result of measuring color in terms of brightness, redness, and yellowness with chromaticity, the L value (brightness) increased with added amount of Hamcho. There was no significant difference in redness or yellowness. As a result of the sensory evaluation of pettitoes according to addition of Hamcho, the group with 4% added Hamcho showed enhanced overall preference with improved flavor, taste and textural properties.

  • 보리, 쑥, 다시마, 대두를 재료로 하고 Bacillus licheniformis Bl을 접종하여, 맛과 향이 향상된 청국장을 제조하였다. 본 혼합발효에서 단백질분해효소의 활성은 발효시작 하루만에 최대치에 이르렀으며, 발효시작 2일만에 pH는 8.4까지 증가하였다. 당과 아미노산에 의해 생성되는 갈변물질은 초기에 비해 20배 이상 증가하였다. 이상으로 대두에 보리, 쑥, 다시마를 혼합하여도 청국장 제조가 가능함을 확인할 수 있었다. Ethanol과 methanol에 녹인 혼합 발효분말의 농도를 각각 0.2에서 1%(w/v)로 증가시킬수록 농도의존적으로 항산화도는 증가하였다. 항산화도는 1,1-diphenyl-2-picrylhydrazyl (DPPH)를 이용하여 결정하였다. Methanol에 1%의 분말청국장을 녹였을 때 항산화도가 가장 높았다. 고혈압군이 본 혼합 발효분말 20 g을 복용했을 때 수축기 혈압이 2시간 지나 10 mmHg 떨어지는 강하효과가 있었다. 또한 맛과 향의 선호도면에서 보리, 쑥, 다시마가 포함된 혼합 발효분말이 발효대두보다 t검정으로 유의적으로 높음을 보였다. 혼합 발효분말은 앞으로 혈압강하용 기능성 청국장으로 개발될 수 있을 것이다.
