稻谷按厚度分级加工后的特性与应用分析

稻谷在成熟过程中,籽粒内部进行着复杂的生物化学变化的同时,籽粒的干物质逐渐积累和含水率逐渐减小。不同厚度籽粒之间的物理性质、物理化学性质和加工特性都具有一定的差异,收获后按照籽粒厚度分级改善了原稻谷籽粒间的不均匀特性,并且改善了其加工适性。改善后的相关特性将在稻谷籽粒的后续加工过程中,如干燥、储藏和深加工等方面,具有更好的适应性。

Characteristics of Rice Fractionated by Rice Kernel Thickness and Its Application

There were complicated biochemical changes in rice grains,and dry matter of rice was accumulated and moisture content of rice decreased gradually during rice maturity.Post-harvested rice grains were fractionated by kernel thickness with grader of slotted screen;there were differences of physical,physicochemical and milling characteristics among grains in various thickness sections.This fractionating process by kernel thickness improved uniformity among grains and applicability of processing product of rice,and the relative characteristics on fractionating process to rice grains could be applied in drying,storing and milling with better the applicability.
