Chemical and biological evaluation of cereal-legume mixtures prepared with normal or genetically improved cereals were made. Wheat, triticale, normal corn, two varieties of opaque-2 corn: soft and hard endosperm, and chick-peas were used. The results showed that although the protein content in the normal and in the genetically improved cereals was similar, the lysine, tryptophan, sulfur amino acids and leucine in the genetically improved cereals gave a better balance in their protein. This was reflected in the protein efficiency ratio values, which demonstrated that the mixtures of genetically improved cereals and chick-peas were statistically different from those prepared with normal cereals. The best results were found with the triticale flour and hard endosperm opaque-2 corn mixtures. It is concluded that the mixtures prepared with genetically improved cereals permit a reduction in the amount of legume in the mixtures maintaining a high protein value and preserving the desirable cereal properties.
对用普通谷物或基因改良谷物制备的谷物-豆类混合物进行了化学和生物学评价。使用了小麦、小黑麦、普通玉米、两种不透明-2玉米品种:软质胚乳和硬质胚乳玉米以及鹰嘴豆。结果表明,虽然普通谷物和基因改良谷物中的蛋白质含量相似,但基因改良谷物中的赖氨酸、色氨酸、含硫氨基酸和亮氨酸在蛋白质中具有更好的平衡性。这在蛋白质效率比值中得到体现,该比值表明基因改良谷物与鹰嘴豆的混合物在统计学上与用普通谷物制备的混合物不同。用小黑麦粉和硬质胚乳不透明-2玉米混合物得到了最佳结果。得出的结论是,用基因改良谷物制备的混合物能够在保持高蛋白值并保留理想谷物特性的同时,减少混合物中豆类的用量。
