  • This article concerned with the nutritional status and the taste of the lunch box of 311 middle school girls in Kwangju City from May 18 to June 12 in 1987. The purpose of this research was making materials to show direction of the education about nutrition by checking relationships among the nutritional status for the lunch box, the taste of food and the environmental factors. The results observed in the study were as follows: 1. The intake of nutrition from the lunch box and the ratio between the recommended dietary allowance and the contained nutrients in the lunch box as follows. Calorie(603 Kcal, 78.6%), protein (21.7g, 93.1%) Animal protein (10.3g, 132.1%) calcium (151.7 g, 56.9%) Ferrum 93.1 mg, 51.7%), Vitamin a (129.3 RE, 55.4%) Vitamin B1 (0.29 mg, 72.5%), Vitamin B (0.26 mg, 55.3%) Niacin (4.7 mg, 94.0%), Vitamin C 913.2 mg, 79.0%). Except animal protein, all the recommended dietary allowance. 2. According to the intake of calorie, the ratio of taken carbohydrate, protein and fat was 77.7 : 15.5 : 6.8. The intake of protein was desirable but most of calorie depended on carbohydrate. Among the total intake of protein, the ratio of animal protein was 47.5%, which was a high rate. 3. Most of calorie (75%), was taken from staples, protein (41.5%), vitamin B1 (48.3%) were taken at the same rate from staples and side dishes. Most of fat, calcium, ferrum, vitamin A, vitamin B, and vitamin C, was taken from side dishes. 4. In taking among the five basic food groups, proportion of the grain fourth food group was the highest, light color vegetable the third food groups, proportion of the grain fourth food group was the highest, light color vegetable the third food group was second, and Calcium food the second food group was the lowest. 5. As the staples, students liked tchajangmyon, mandu and ttokkuk as written order. They disliked Kongbap and Patpap. As the side dishes for the lunch box, they liked kimchi, ham, sausage, cuttlefish, dried slices of filefish, eggs and green seaweed as written order. As a side dishes they liked Laver, Cucumber, Squid, lettuce, Potatoes. They disliked pork fat, cow's intestines, cow's liver, Crussian carp, pickled fish. The favorite snack was fruits, ice cream, hamburger, Chocolate and milk. 6. In taking condition of the principal food, rice rate (65.6%) was the most, and mixed food was 5 or 10%. 7. Favorite cooking was frying, roasting and kimch. But disagreeable cooking was pickling. 8. Favorite food was what was pungent but disagreeable food was what was salty. 9. the higher parents educational background was, the higher their income was. Also the more various the information about the nutrition was, the better the intake of nutrition was. 10. The preference tendency influenced in choosing the side dish of the Lunch box. The higher the preference tendency of the girl students became, the better their nutrition condition became.

  • 본 연구에서는 우리의 전통한과인 유과의 가공방법과 저장성을 향상시키기 위하여 저장 중 황산화제를 첨가하여 유과를 제조한 후 저장기간 동안 품질변화를 측정하고자 하였다. 유과를 상온에서 저장하면서 색을 측정한 결과 백색도(L)의 경우 모든 처리구에서 약간 감소하거나 거의 변화가 없는 경향을 보였고, 적색도(a) 및 황색도(b)의 경우는 모든 처리구에서 감소하였다. 텍스쳐에 있어서 상관성을 보이는 경도와 씹힘성의 경우 전반적으로 감소하는 경향이었다. 저장 중 산패의 지표인 과산화물가는 YOP1 및 YOP2 처리구는 저장 12주까지 식품위생규격 및 전통식품표준규격에서 정한 한과류에 대한 기준치인 40이하로 측정되었다 포장방법별로 2주에서 12주까지 저장하면서 유과에 함유된 지방성분 중 지방산을 측정해 본 결과 저장초기의 지방산 함량과 차이를 보이지 않았다. 저장초기의 지방산 함량은 palmitic acid 11.3%, stearic acid 4.6%, oleic acid 23.4%, linoleic acid 54.2%, linolenic acid 6.5%로 불포화지방산인 linoleic acid와 oleic acid가 가장 많았다. Electronic nose를 이용하여 대조구와 처리구간의 향기특성 패턴을 분석한 결과 8주부터 10주까지는 항산화제를 처리한 것이 차이가 적었다. 저장 중 유과의 향기특성에 대한 관능적 특성(Yukwa odor, rancid odor)과 전자코(electronic nose) 측정치간의 비교에서 전자코 측정치에서도 향기특성이 대조구와 큰 차이가 없게 나타나 관능적 평가 결과와 기계적 특성치가 유사한 경향을 보였다.
