摘    要:为探究α-环糊精对糯米淀粉凝胶特性的影响。本文以糯米淀粉为原料,将α-环糊精(0%-10%)与糯米淀粉共混,测定淀粉凝胶的微观结构、流变特性、糊化特性、质构特性和短程有序性。结果表明:随着α-环糊精的添加,淀粉凝胶网络结构中的孔洞分布变得均匀。此外,α-环糊精的存在降低了淀粉凝胶的G′、硬度、回生值,但显著提高了凝胶的弹性和透明度。傅里叶红外结果表明,糯米淀粉的短程有序性随着α-环糊精添加量的增加而逐渐下降,α-环糊精与糯米淀粉之间并未发生化学反应。

关 键 词:糯米淀粉;α环糊精;凝胶特性

Abstract:To investigate the effect of α-cyclodextrin on the gel properties of glutinous rice starch. In this paper, α-cyclodextrin (0%-10%) was blended with glutinous rice starch as raw material to determine the microstructure, rheological properties, pasting properties, textural properties and short-range ordering of the starch gel. The results showed that with the addition of α-cyclodextrin, the distribution of pores in the network structure of starch gel became uniform. In addition, the presence of α-cyclodextrin decreased the G′, hardness, and regrowth values of starch gels, but significantly increased the elasticity and transparency of the gels. The FTIR results showed that the short-range ordering of the glutinous rice starch gradually decreased with the increase of α-cyclodextrin addition, and there was no chemical reaction between α-cyclodextrin and glutinous rice starch.
Keywords:glutinous rice starch   α-cyclodextrin;Gel properties
