摘要
论述了淀粉与改性淀粉的颗粒形貌、结晶类型、分子结构及其功能性质。不同淀粉颗粒的形状和大小也不同,有圆球形、椭球型、卵圆形和不规则的多角形;根据淀粉的消化速率,淀粉可分为快消化淀粉、慢消化淀粉和抗性淀粉;根据淀粉的结晶结构,淀粉可分为A型、B型、C型和V型淀粉;可用红外光谱和拉曼光谱表征淀粉的分子结构;淀粉的功能由淀粉的结构决定。
The particle morphology,crystal type,molecular structure and functional properties of starch and modified starch are discussed in this paper.The shapes and sizes of different starches vary greatly,including spherical,ellipsoidal,oval,and irregular polygonal shapes.According to the digestion rate of starch,it can be divided into fast digestible starch,slow digestible starch,and resistant starch.According to the crystal structure of starch,it can be divided into A-type,B-type,C-type,and V-type starch.The molecular structure of starch can be characterized by IR and Raman spectra.The function of starch is determined by its structure.
