Physicochemical Properties of Wheat Starch Granules
摘要
Abstract
Four types of commercially available wheat flour,Wudeli(WDL),Jinyuan(JY),Jinxiang(JX),and Sifeng(SF),were used as raw materials for starch extraction and characterization.Total starch,A starch,and B starch samples were obtained through extraction and separation.Differences in the starch compositions,amylose contents,particle sizes,transparency,pasting characteristics,thermal characteristics,and dynamic rheological properties were analyzed.The A and B starches from the four wheat flours were effectively isolated,with their physicochemical compositions showing a direct correlation with the granule type.Specifically,A starch exhibited a higher amylose content(31.92%～35.27%),lower levels of protein(0.25%～0.27%),ash(0.10%～0.13%),and damaged starch(18.15%～20.85%);whereas B starch exhibited a higher pasting temperature(68.90～71.55℃)and range.In terms of the total starch content among the four types of wheat flour,the size distribution range was in the following order:SF>JX>WDL>JY.Notably,JY exhibited a higher amylose content(31.91%),an initial pasting temperature of 54.78℃,and an enthalpy of pasting of 10.33 J/g.In contrast,WDL demonstrated a lower regrowth viscosity,at 303.50 cP.Dynamic rheological analysis revealed a high frequency dependence of B starch,as well as high elastic and viscous moduli of SF total starch.The most notable differences were in the properties of the JY and SF total starches.Specifically,JY exhibited higher crystallinity and thermal resistance,and SF total starch greater gelatinizability and superior viscoelastic properties.The results provide theoretical guidance for multi-scale analysis of wheat starch.关键词
