摘要: 以提纯的小麦胚乳A型和B型淀粉粒为测定对象,比较研究了A、B型淀粉粒的淀粉组成与糊化特性。结果表明,A型淀粉粒直链淀粉含量显著高于B型淀粉粒,而支链淀粉含量显著低于B型淀粉粒。与B型淀粉粒相比,A型淀粉粒含有较高的直/支链淀粉比。B型淀粉粒RVA参数中峰值粘度、低谷粘度、稀懈值、最终粘度、反弹值、峰值时间和糊化温度均显著高于A型淀粉粒。原因可能是小颗粒淀粉(B型淀粉粒)内部结构紧密,淀粉糊化较大颗粒淀粉(A型淀粉粒)困难。

Abstract: Two types of starch granule A and B type starch granule were separated in wheat grain in this study.The starch composition contents and pasting properties in starch granules were studied and compared. The resultshowed that amylose content of A type starch granule was significantly higher than that of B type starch granule,andamylopectin content of A type starch granule was significantly lower than that of B type starch granule. Thus the ratioof amylose to amylopectin of A type starch granule was high compared with B type starch granule. RVA parametersincluding peak viscosity though viscosity breakdown peak time and pasting temperature of B type starch granulewere significantly higher than those of A type starch granules. These may be due to B type starch granules were well-set compared with A type starch granules.

Key words: Wheat, Starch granule, Starch, Pasting properties
