直链淀粉含量适中籼稻品种间的食味品质差异分析

为研究适中直链淀粉含量品种间的食味品质差异,对24份直链淀粉含量达到农业部一级优质食用稻米标准的籼稻品种进行了分析。结果表明:长宽比、胶稠度、碱消值、崩解值与食味品质达到了极显著正相关水平,粒宽、垩白率、消减值、回复值、蛋白质含量与食味值达到了极显著负相关水平。食味品质较好的品种粒宽、垩白率、垩白度、回复值和消减值应较小,蛋白质含量较低,长宽比、胶稠度、崩解值较大。通径分析表明,长宽比、胶稠度、碱消值对食味品质具有较大的直接作用。本研究结果可为今后完善稻米品质评价指标及稻米食味品质改良提供理论依据。

Analysis on Edible Quality Differences Between Varieties of Indica Rice with Medium Amylose Content

In order to study the edible quality differences between indica rice varieties,24 indica rice varieties with medium amylose content,which had reached the first class standard of edible quality by Ministry of Agriculture,were analyzed.The result indicated that the length/width,alkali spreading value,gel consistency,breakdown viscosity of rice were significant positive correlated with edible quality,but the edible quality were negatively related to grain width,chalky rate,protein content,consistence viscosity...
