【摘要】 本文报道了米胚芽添加剂的营养价值。实验分为四组:第1组和第2组大鼠分別饲以10％和20％米胚添加剂;第3组饲以1.1％酪蛋白添加剂作为阳性对照;第4组以基础饲料作为空白对照。前三组蛋白质含量(g/100g饲料)基本对等,而热量(kcal/100g饲料)四组基本对等。 结果表明:实验组和空白对照组比较,身长和体重均有非常显著差异(p<0.01);而米胚组和酪蛋白组比较差异不显著(p>0.05)。10％米胚添加剂组摄食量多,生长速率与1.1％酪蛋白添加组相似,较20％米胚添加组略优,体重增长雄性比雌性明显,血红蛋白含量,大脑、脾脏和胸腺重量,四组均无显著差别;三个实验组的蛋白质功效值、食物效能和热量效能较近似,但显著地高于不加米胚组。 结果提示:10％米胚添加剂的营养价值与1.1％酪蛋白相当,可考虑做为人类蛋白质和维生素的新的食物资源。更多还原

【Abstract】 The nutritional value of rice germ additive was evaluated by biological method. The experiment was divided into four groups: in the first and second groups the rats were fed with 10% and 20% rice germ additive, the third group as a positive control received 1.1% casein additive, and the fourth was rice germ free group. The main nutrients such as protein, fat and carbohydrate contents in the first three groups were basically equal.The experimental results showed that the growth curve and other criteria of the rice germ additive were as same as the 1.1% casein additive group but 10% rice germ group was slightly better than the 20% group, especially the weights of males were increased more rapidly than the females.At the end of the experiment, no significant differences were found among the four tested groups in hemoglobin contents, weights of cerbrum, spleen and thymus. The data indicated that the nutritional effect of 10% rice germ additive was comparable to 1.1% casein additive. So the rice germ may be acceptable as a new potential source of protein, vitamin and mineral for human and animal foods.更多还原
