外源蛋白基因对棉籽营养成分影响的研究

本研究通过对转Bt毒蛋白棉花的各种营养成分、矿物质含量、氨基酸含量以及抗营养因予成分的检测与分析，评价Bt等外源基因对棉籽营养成分的影响，为转基因产品的安全评价提供依据。通过检测证明，转基因棉籽和非转基因棉籽在营养学方面具有实质等同性。

Effect after Introducing Bacillus thuringiensis Gene on Nutritional Composition Changes in Cottonseed

Compositional analyses including protein, oil, fiber, moisture mineral content were performed on the cottonseed to assess the effects on compositional components change after introducing Bacillus thuringiensis gene. The results demonstrated that the transgenic cottonseed was comparable to the nontransgenic cottonseed within the established ranges for commercial cotton varieties. Anti-nutrients were also measured and comparisons again showed no material difference with respect to the control. The results of numerous analytical assay of the compositions demonstrated that the transgenic cottonseed was compositionally equivalent to the conventional one.
