Starch is one of the organic compounds after cellulose found most abundantly in nature. Starch significantly varies in their different properties like physical, chemical, thermal, morphological and functional. Therefore, starch is modified to increase the beneficial characteristics and remove the shortcomings issues of native starches. The modification methods can change the extremely flexible polymer of starch with their modified physical and chemical properties. These altered structural attributes are of great technological values which have a wide industrial potential in food and non-food. Among them, the production of novel starches is mainly one that evolves with new value-added and functional properties is on high industrial demands. This paper provides an overview of the rice starch components and their effect on the technological and physicochemical properties of obtained starch. Besides, the tuned techno-functional properties of the modified starches through chemical modification means are highlighted.HighlightsNative and modified starches varies largely in physicochemical and functional traits.Modified physical and chemical properties of starch can change the extremely flexible polymer of starch.Techno-functional properties of the modified starches through chemical modification means are highlighted.Dual modification improves the starch functionality and increases the industrial applications.Production of novel starches is on high industrial demands because it mainly evolves with new value added and functional properties.
淀粉是自然界中除纤维素外含量最丰富的有机化合物之一。淀粉在物理、化学、热、形态和功能等方面的性质差异很大。因此,淀粉被改性以增加有益特性并消除天然淀粉的缺点。改性方法可以改变淀粉非常灵活的聚合物,并改变其改性的物理和化学性质。这些改变的结构属性具有很大的技术价值,在食品和非食品领域具有广泛的工业潜力。其中,新型淀粉的生产主要是一种随着新的附加值和功能性的发展而演变的淀粉,具有很高的工业需求。本文综述了大米淀粉的组成及其对获得淀粉的技术和物理化学性质的影响。此外,还强调了通过化学改性手段对改性淀粉的调控制技术功能性质。
