利用RINT2000 vertical goniometer型X-衍射仪测定经高压处理的橡实淀粉的晶体特性,研究高压处理对橡实淀粉晶体特性的影响规律.结果表明:高压处理不会改变淀粉的晶体类型,对淀粉晶相有一定的影响.高压处理对淀粉晶相结晶度有极显著影响,对微晶相结晶度有显著影响,对亚微晶相结晶度有一般显著影响.高压处理时淀粉含水率对其结晶度有极显著影响,含水率越高,其结晶度越低.高压处理时的压力大小对淀粉晶相、微晶相结晶度显著影响,高压处理的压力增加,其结晶度降低,在一定条件下延长保压时间可以补偿压力不足的现象.

Effect of high pressure treatment on the crystalline properties of acorn starches was studied by RINT2000 vertical goniometer. Results show that high pressure treatment can not change the crystal type; high pressure treatment has a definite effect on the crystal type of acorn starches. The pressure treatment has the best significant effect on the crystallinity, more significant effect on the micro-crystallinity, and significant effect on sub-crystallinity of the starches. High water content has more significant effect on the crystallinity during high pressure treatment, when the water content ...
