摘要:

探讨主成分分析在即食玉米加工用品种筛选中的应用,筛选甜糯玉米加工品质的有效指标。选取11 个甜糯玉米品种,测定影响即食玉米加工的主要营养成分,并对各指标进行主成分分析。主成分分析结果表明即食玉米加工品质由3 个主成分构成,其中支链淀粉对即食玉米加工品质的贡献率最大,占43.232%,筛选出可作即食玉米加工用的品种为苏试80618 和京甜紫花糯2 号。

Abstract:

Principal component analysis (PCA) was exploited in variety screening for instant corn, and the effective indicators for its processing quality were examined. Among selected 11 sweet-waxy corn varieties, major nutritional components affecting instant corn processing were determined. Results showed that the processing quality of instant corn was constituted by 3 principal components. Amylopectin exhibited the biggest contribution to processing quality of instant corn, which was account for 43.232%. Sushi 80618 and Jingtianzihuanuo No. 2 were selected and could be used for the preparation of instant corn.

Key words: instant corn, processing quality, variety screening
