Effects of Amylose Content on RVA Profile Character of Millet Starch

  • Received:2010-02-26 Revised:2010-03-17 Online:2010-08-05 Published:2010-08-05

摘要:

利用快速粘度分析仪(RVA)分析了东北地区新近培育的春谷新品种(系)淀粉粘滞性,结果表明不同品种(系)具有特征性RVA谱。以消减值可有效区分出品种(系)直链淀粉含量(AC)的高低。低AC 品种(系) 消减值一般较低,中等或高直链淀粉含量品种(系) 消减值较高。相近直链淀粉含量品种(系)间食用品质的优劣,可根据消减值和崩解值判断。RVA谱特性可望作为理化标记在优质谷子育种中发挥重要作用。

Abstract:

Rapid Visco Analyzer (RVA) was used to investigate different spring millet varieties (lines), were
analyzed. Different varieties had distinct RVA profiles, and the varieties (lines) with low or high amylose
content (AC) could be quickly distinguished by the setback. According to the values of breakdown and setback,
it could evaluate the superior or starch viscosity of millet varieties with similar AC the breakdown value of
RVA profiles was closely related to del consistency and millet taste, and the setback value was linked to millet
texture. It suggested that the characteristics of RVA profiles could be used as an important physical and
chemical marker to assisted-selecting good quality millet.
