摘要:

采用快速黏度分析仪(RVA)分析全国27 个小米品种的RVA 谱线和各特征值间的相关性。结果表明:小米品种间的RVA 谱特征值差异显著,小米衰减值的测定对于小米的品种鉴别具有较强的区分能力;直链淀粉含量与衰减值呈极显著负相关,与回生值呈极显著的正相关。可以利用直链淀粉含量并辅助RVA 谱特征值进行小米品质的鉴定。

关键词: 小米, 糊化特性, 直链淀粉含量, RVA 谱

Abstract:

Rapid visco analyzer was used to analyze the RVA spectra of 27 millet varieties and correlations among RVA eigenvalues were explored. The results showed that there was a significant difference in RVA eigenvalues among different millet varieties. The measurement of millet attenuation values provided an effective discrimination for 27 millet varieties. Amylose content was negatively correlated with attenuation values but positively correlated with retrogradation values. Therefore, RVA determination combined with amylose content provides a good approach for the identification of millet quality.

Key words: millet, gelatinization characteristics, amylose content, RVA spectrum
