摘要
淀粉和膳食纤维是谷物重要的组成成分,粉碎是谷物最普遍的加工方式,然而粉碎加工处理常常会引起谷物淀粉及膳食纤维性质的改变,淀粉、膳食纤维与蛋白质的相互作用也会改变,进而影响面团和面制品终产物的品质。从淀粉分子、晶体、颗粒3个水平综述了粉碎对谷物淀粉结构与性质的改变及对面团糊化特性、热力学特性的影响;从膳食纤维的粒径大小、吸水性及其与淀粉、蛋白互作3个角度综述了粉碎对谷物膳食纤维性质的改变及对面团流变学性质、面制品品质的影响,以期为谷物粉碎工业提供理论技术指导。
Whole grain foods are one of the most popular healthy foods,as they are nutritious and able to prevent many diseases. Starch and dietary fiber are important compositions of grains,however,milling can affect their natural properties. Additionally,the interactions among starch,dietary fiber and protein can also be affected by milling,which could influence the qualities of dough and final products. This paper summarized the changes in structures and properties of milled starches at molecular,crystalline,and granular levels,as well as their effects on gelatinization and thermodynamics properties of the dough. Moreover,effects of milling on the properties of dietary fiber,the rheological properties of dough,and the quality of flour products were discussed regarding the particle size,water absorbing capacity,and interactions between fiber,starch and protein. Overall,this study provides a theoretical guidance for developing grain milling industries.
