制备方法对小麦淀粉-油酸包合物的热性质及消化性质的影响
Effect of Preparation Methods on Thermal Properties and Digestibility of Wheat Starch-Oleic Acid Inclusion Complexes
摘要
Abstract
The effect of two different preparation methods,namely HCl/KOH and rapid visco analyzer (RVA),on thermal properties and digestibility properties of wheat starch-oleic acid inclusion complexes was studied by differential scanning calorimetry,thermogravimetric analyzer and X-ray diffraction.The results indicated that different preparation methods affected thermal properties and digestibility properties of wheat starch-oleic acid inclusion complexes.The crystal types of wheat starch-oleic acid inclusion complexes prepared by both methods were type-V.Wheat starch-oleic acid inclusion complexes prepared by RVA method revealed an increase in complex index,glass transition temperature,thermal decomposition stability,ordered degree of short-range structure of particle surface,and the contents of slowly digestive starch and resistant starch and a decrease in relative crystallinity,onset temperature,gelatinization enthalpy,the content of rapidly digestive starch,hydrolysis degree,relative digestibility and predicted glycemic index compared with those prepared by HC1/KOH method.These two samples had a medium glycemic index.关键词
