摘要
微波是一种能以高频的方式使物质在电磁场中加热的非电离能量。本文研究了淀粉经微波作用后性质的变化,结果表明,微波作用后淀粉的颗粒形貌没有发生变化,偏光十字存在,部分颗粒脐点表面出现小孔,X-射线主要衍射峰的强度增大,晶型由B型转为A型。
Microwave energy is the non-ionizing energy source because it creates heat deep within the materials being processed as a result of rapid changes of the electromagnetic field at high frequency. This paper studies the change of properties of starches after microwave radiation. The results showed that the shape did not change, polarized cross existed and a concavity of the surface at the center of some starches could be clearly observed. Microwave treatment increased the X-ray intensities of the major dspacing of starch and changed the X-ray pattern of (B→A) high amylose corn starch.
