摘要
研究了600MPa超高压下,不同浓度的CaCl2介质对马铃薯淀粉结构的影响。应用偏光显微镜和X-射线衍射对样品进行了分析测试,结果表明,不管浓度大小如何,CaCl2均可以抑制淀粉的糊化,其偏光十字均保持得较好;低浓度的CaCl2对马铃薯淀粉的结晶结构影响不大,高浓度的CaCl2则由于渗透作用而导致淀粉结晶结构部分发生破坏。
The influences of CaCl2 on the structure of potato starch were studied in different concentration at 600 MPa. The products were detected with X-ray diffraction and polar optic, al mierosc, opy. The results showed that it could be used to restrain the gelatinization for the low concentration, and the cross was clear. The effect of CaCl2 on the crystal structure of potato starch were weak in low concentration of CaCl2, but it destroy the crystal structure partly in high concentration by the permeation of CaCl2.
