吉林农业大学食品科学与工程学院、中国热带农业科学院香料饮料研究所、国家重要热带作物工程技术研究中心、海南省特色热带作物适宜性加工与品质控制重点实验室的王金梦、张思维、赵康云、陈小爱、张彦军等人介绍了木薯淀粉的理化和结构性质,以及不同品种木薯淀粉之间的差异。前人主要集中在粒径、颗粒形态、糊化特性、热力学特性等方面进行研究,但国内关于不同品种木薯淀粉的理化和结构性质的研究尚缺乏系统报道。本文选取华南9号、华南10号、华南11号、桂热891和桂热911五个不同品种木薯为原料,提取淀粉,对比五种木薯淀粉在颗粒形态、粒径、热力学特性、有序结构等理化和结构性质的差异,为木薯育种、新品种开发利用和木薯淀粉在食品工业和非食品工业的应用提供理论依据。

Abstract: In this paper, five different species of cassava (SC9, SC10, SC11, GR891 and GR911) were used as raw materials and starch was isolated to study the differences in physicochemical and structure properties. The results showed that the amylose content of SC9 was the lowest (22.56%), and GR911 was the highest (27.49%). The surface of all species of cassava starch showed smooth and irregular spherical shape with the particle size of 12.43~19.03 μm. SC9 had the smallest particle size (12.43 μm), solubility and swelling power (10.35%, 28.00%), while GR911 showed the largest particle size (19.03 μm), solubility and swelling power (15.21%, 35.00%). All starches showed typical A-type crystal structure. The SC9 showed the highest (26.49%) relative crystallinity and GR911 was the lowest (21.92%). The SC9 had the lowest (0.756) short-range order structure compared to the highest (0.882) for GR911. According to the gelatinization properties, the species of SC9 and SC10 could be used as food thickeners or gelling agents. The species of GR911 was suitable for filling candy or weaned food. The species of SC11 and GR891 could be used as sticky food. The results of this study could provide a theoretical reference for the selection of cassava starch suitable for processing in the food industry.
