大麦强、弱势粒胚乳淀粉体发育及淀粉理化性质的比较研究
Comparison study on development of endosperm amyloid and physicochemical properties of starch from superior and inferior grains inbarley
摘要
Abstract
In order to investigate the differences of endosperm amyloid development and physicochemical properties be-tween superior and inferior grains in barley,white highland barley C2-2 was used as material in this study and the struc-tural characteristics of amyloid development in barley endosperm were observed by resin slicing.Meanwhile,starch was extracted from mature barley grains to determine its physicochemical properties,such as morphological,structural,and functional prameters.The results showed that the development of endosperm amyloid in barley superior grains was better than that in inferior grains,and the filling degree of endosperm amyloid in superior grains was higher.The morphology and crystal type of superior and inferior grains starch were basically similar,but the structure of starch was different.The relative crystallinity of starch from superior grains was significantly higher than that of inferior grains,while the ratio of 1 022/995 cm-1 was significantly lower than that of inferior grains.Moreover,the peak viscosity,trough viscosity and final viscosity of barley superior grains starch were significantly higher than those of inferior grains starch,showing better pasting properties.关键词
