Abstract

Abstract:

【Objective】 To examine the distinct starch functional properties among various rice cultivars in Xinjiang and to establish a theoretical foundation for rice processing.【Methods】 Fifteen varieties of rice cultivated in Xinjiang served as the fundamental material and the starch was obtained through an alkaline method; Various parameters like amylose and straight-chain amylose content, sedimentation product, freeze-thaw stability, transmittance, pasting characteristics, textural characteristics, solubility, swelling, etc.were assessed.The statistics were then subjected to significance of differences analyses, correlation analysis, and principal component analysis.【Results】 The amylose content and linear amylose content of the 15 rice types differed significantly (P< 0.05).Xining 9 had the highest linear amylose content (28.88%).Solubility also differed significantly (P< 0.05), and the swelling degree ranged from 59% to 70%.Freeze-thaw stability decreased with the number of freeze-thaw cycles, and transmittance decreased with increasing resting time.Daomi 56 and Xinjing 9 had the highest chewing resistance.There was a significant correlation between the rice varieties and the straight-chain amylose content of the starch, pasting properties, and textural properties.Xinjing 9 had the highest score.Various types of rice exhibited differences in their physicochemical and functional characteristics.Xinjing 9 variety, in particular, was found to possess favorable processing characteristics.【Conclusion】 The outcomes of this study offer a theoretical underpinning for rice variety selection and processing in Xinjiang.

摘要：

【目的】 研究新疆不同品种大米淀粉功能特性差异,为大米加工提供理论依据。【方法】 以新疆种植15种不同的大米品种为材料,采用碱法提取淀粉,测定总淀粉和直链淀粉含量、沉降积、冻融稳定性、透光率、糊化特性、质构特性、溶解度和膨胀度等参数,并对各指标进行显著性、相关性和主成分分析。【结果】 15种大米的总淀粉、直链淀粉含量显著差异(P<0.05),新粳9号直链淀粉含量最高(28.88%);溶解度差异显著(P<0.05),膨胀度在59% ~ 70%。冻融稳定性与冻融循环次数成反比,透光率随静置时间的增加而减小。稻米56号和新粳9号的耐咀嚼性最佳,大米品种与淀粉的直链淀粉含量、糊化特性、质构特性呈显著相关性,新梗9号得分最高。【结论】 不同品种大米理化、功能特性存在差异,其中新粳9号具有良好的加工特性。
