Spectroscopic Properties of in vivo and in vitro Digestive Resistant Starch from High-Amylose Transgenic Rice
摘要
Abstract
In this study, the spectroscopic properties of in vivo and in vitro digestive resistant starches from a high-amylose transgenic rice line （TRS） established through antisense RNA inhibition of starch branching enzymes were investigated by X-ray powder diffraction and Fourier transform infrared spectroscopy. The results showed that the amylose contents of non-digestive TRS resistant starch significantly increased. TRS starch was C-type crystalline starch, a mixture of A- and B-type crystalline starches. The degradation of the A-type crystalline starch was faster than that of B-type starch, and the B-type crystalline starch showed a high resistance to digestion. The amorphous starch of starch granule was easy to be degraded. These data could be useful for various applications of high-amylose crop in the food and nonfood industry.关键词
