This study evaluated the quality characteristics of Garaeduk, a traditional Korean rice cake, to which Spirulina (0, 1, 2, 3%, all w/w) was added. Moisture content of Spirulina-containing Garaeduk both before and after cooking increased with Spirulina level. During storage, moisture content was greater in Spirulina-containing cakes compared with control cakes, and the Hunter color L and b values of Spirulina-containing cakes decreased. Textural properties (hardness, chewiness), measured using a texture analyzer, of Spirulina-containing cakes were greater than those of control. During storage, hardness and chewiness of Spirulina-containing cakes remained higher than those of control cakes. The antioxidant activities of Spirulina-containing cakes increased with Spirulina content, owing to increased phycocyanin levels. Amylography showed that peak viscosity, and thus gelatinization temperature, of Spirulina-containing Garaeduk cakes were similar. Sensory preference tests revealed that Garaeduk with 2% Spirulina had the highest scores for color, odor, taste, and overall preference. It is suggested that Spirulina to 2% can be added to Garaeduk to improve quality.

향신채소인 부추, 미나리의 부가가치를 창출하고 이들의 생리활성을 활용한 기능성 가공식품의 개발을 위해 제조한 국수의 제품질을 평가한 결과는 다음과 같다. 부추 및 미나리는 열풍건조, 블렌칭 처리후 열풍건조, 찜 후 열풍건조 그리고 동결건조로 나누어 각각 건조후 분말화하였다. 건조분말의 품질평가에서 비타민 C, 클로로필함량, 페놀성 화합물 함량이 열풍과 동결건조 처리구에서 높았고 전자공여능도 높게 나타났다. 국수의 조리 후의 특성에 있어 부추와 미

To enhance the utilization of garlic shoots as food material, the nutritional and volatile flavor com pounds were investigated for garlic shoots, both cold and warm region type garlic shoots. Proximate composition of cold and warm region type was as follows, respectively; crude protein 2%, crude lipid 0.4%, crude ash 1.1% and 1.5%, crude fiber 1.3% and 1.5%. The major fatty acids of 2 varieties of garlic shoots were linoleic, palmitic and linolenic acid, and their desaturation ratio of them was comparatively high, showing 73.7 and 66.8%, respectively. Free sugars were composed of glucose, sucrose, fructose, arabinose and sorbitol. In the total amino acid analysis, the major amino acids were glutamic acid and aspartic acid. The volatile flavor compounds of fresh garlic shoots extracted by hexane and Likens-Nikerson steam distillation apparatus were identified to be methyl-2-propenyl disulfide, diallyl disufide, propenyl propyl disulfide, di-2-propyl-trisulfide, 2-vinyl-1,3-dithiane, and 2-vinyl-4H-1,3-dithiin. Hexane was more effective than steam distillation for extraction of volatile components of garlic shoots.

To study the shelf-life of cut cabbage kimchi, we examined the several quality characteristics of cabbage kimchi under various storage temperatures and packing materials. The pH of kimchi extracts were decreased to 4.0 in the condition of storage at 8 during 6 days, at 4 during 18days, 0 during 42 days. The increase patterns of the organic acid were reverse to the changes of pH under the all conditions. The contents of reducing sugar were continuously decreased at 8 , but increased gradually at 0 and 4 storage conditions. The contents of vitamine C were decreased at the early storage but increased to optimum ripening stage of pH 4.2-4.4 and after decreased continuously. The total bacterial cell counts of cabbage kimchi were increased suddenly at the early storage and after decreased gradually. And at the higher storage temperature, the more lactic acid bacteria were. On the results of sensory evaluation of cabbage kimchi at marketable shelf-life, sour taste and sour smell were significant under all experimental conditions by Duncan's multiple range test. On the above all results, we concluded that the marketable shelf-life of cut cabbage kimchi were 42 days, 19 days, 6 days at 0, 4, 8 storage condition respectively.
