Fundamental Study on Nutritional Evaluation for Rapeseed Meal
田所忠弘(Tadahiro Tadokoro),久保和弘(Kazuhiro Kubo),山田和弘(Kazuhiro Yamada),太田徹(Toru Ota),前川昭男(Akio Maekawa),한양일(Yang-Il Han) 한국식품영양과학회 1994 한국식품영양과학회지 Vol.23 No.3
식물유자원으로서 사용이 증가되고 있는 유채에 대한 영양학적인 기초연구를 목적으로 유채의 일반성분, glucosinolate, amino acid 분석을 시도하였다. 또한 유채종자의 주 성분인 단백질의 품질을 측정하기 위하여 20% 수준이 단백질을 사료로 Wistar계 수컷쥐를 사육하여 사료효율(FER), 단백질효율(PER), 정미단백질효율(NPU), 소화율(TD) 및 생물가(BU)를 측정하였으며 장기중량과 혈액성분도 아울러 조사했다. 조 단백질량은 탈지대두 45.5%, 탈지유채종자 37.9%였고, 조섬유량은 탈지대두 5.0%에 비교해서 탈지유채 종자에서는 10.5%로 약 2배였다. 또한 glucosinolate량은 0.04%였다. 탈지유채종자군은 탈지대두군과 비교해서 체중 증가에 유의차는 인정되지 않았으며, 동등한 성장을 나타냈다. 장기중량, 혈중성분에도 특별히 유의한 차이는 없었다. 또한 정미단백질효율도 유의차가 없었다. Rat에 의한 in vivo 실험에서 탈지유채 종자에 많이 함유된 단백질은 탈지대두단백질과 거의 동등한 영양적 가치를 갖는 것으로 생각되며, 앞으로 식품에의 응용 이용이 가능하다고 할 수 있다. This fundamental study was undertaken to evaluate the nutritional value of Canola rapeseed meal which has been increasingly used as a by-product with the demand for the food oil resource. To compare the nutritive values among rapeseed meal and soybean meal, two experiments were carried out by using rats. One was a digestibility test of rapeseed meal and the other was the growth rate of rats for 21 days. The chemical compositions, glucosinolate and amino acids of defatted rapeseed meal and defatted soybean meal were analyzed. After one week feeding, nitrogen excretion in rats was measured to study FER, PER, TD, BW, and NPU of the meals. The amount of crude proteins in defatted rapeseed meal and defatted soybean meal were 45.5% and 37.9%. The glucosinolate content of defatted rapeseed meal was 0.04%. The body weight gain of defatted rapeseed meal was not significantly different from that of defatted soybean meal (p>0.01). After one week feeding, there was no significant differences in organ weights and serum components between two groups (p>0.01). It was presumed that the rapeseed meal has enough possibility for developing food to use as a protein source like a soybean meal protein. However, more careful experiments are needed to clarify the nutritional value of rapeseed meal of Canola since the lipids composition of blood tended to be different when the rapeseed meal and soybean meal were used.

The volatile components of cooked glutinous rice were investigated. Among more than 100 volatile components of fresh cooked rice, the predominant one was hexanal followed by pentanal, butanal, octanal, heptanal, noananal, acetone and toluene. These eight components comprised about 85% of the total volatiles, and the hexanal comprised about 86% total amount of the eight volatile components. the amount of the eight volatile components and hexanal in cooked glutinous rice were six and nine times more than that of cooked nonglutinous rice, respectively. The amount of volatile components in cooked glutinous rice stored for 72 hours at 70℃ was same with that of in nonglutinous rice immediately after cooking.
