2、与其他品质性状间的相互关系,选用2种穗型水稻,以其穗部位置不同的稻谷粒为试验材料,测定粳稻米蒸煮食味品质与其他品质性状进行典型相关分析。结果表明,粳稻米的蒸煮食味品质与粒形特征、垩白性状、碾磨品质、营养品质和淀粉RVA谱特征值显著相关。典型相关分析表明,蒸煮食味品质与淀粉RVA谱特征值和碾米品质相关性最高,与垩白性状相关度较高,与营养品质和粒形性状相关性相对较低。淀粉RVA谱特征因子主要通过峰黏度、冷胶黏度和热浆黏度对食味值、直链淀粉含量和胶稠度的作用来影响蒸煮食味品质优劣。碾磨因子则主要通过整精米率对直链淀粉含量的作用来影响
3、蒸煮食味品质。垩白因子中主要通过透明度和垩白度的作用影响蒸煮食味品质。营养因子主要通过脂肪酸含量、清蛋白含量和谷蛋白含量对食味值、直链淀粉含量和糊化温度的作用而影响蒸煮食味品质好坏。粒形因子主要通过粒宽、粒长和长宽比对食味值和胶稠度的作用来影响蒸煮食味品质。淀粉RVA谱特征值可以作为评价粳米蒸煮食味品质优劣的首选指标。关键词粳稻米;蒸煮食味品质;品质性状;典型相关分析中图分类号S511.03文献标志码A文章编号1004-1389(2015)01-0060-08CanonicalCorrelationbetweenCooking
