Soy bean milk, prepared in the Korean manner, had approximately the same protein content as cow milk. The other nutrient compounds were present in soy bean milk to a lesser extent than in cow milk.Soy bean milk curdled spontaneously at a lower acidity than cow milk. However, the same period of time was required for spontaneous curdling.In the feeding experiments, the ration containing soy bean milk produced gain in weight less rapidly than the ration containing cow milk, and with less efficiency, i.e., with the consumption of more ration per unit of gain in weight.In feeding experiments, chicken protein was found to be a less efficient protein than casein. 相似文献

The liquor from pitchers of Nepenthes, which were entirely free from insect captures, contained a protease which exerted its activity in a slightly acid medium. Catalase, urease, esterase, diastase, invertase, maltase, lactase, and emulsin were not present in the pitcher liquor.A substance, which reduced Benedict alkaline copper solution, was frequently, but not invariably, present in the pitcher liquor; it was probably sugar derived from the nectar.The pitcher liquor contained chlorides, and did not contain phosphates and saponins.A composite sample of the secretion of the leaves of Dionæa muscipula was examined, and was found to contain a protease which was active in the presence of 0.2 per cent. hydrochloric acid.The leaves of Dionæa miiscipula have been analyzed; and their composition is reported.The author is indebted to Dr. Walter Steckbeck for the photograph of Dioncæa muscipula and to Dr. John M. Macfarlane for those of Nepenthes. 相似文献
