低聚果糖添加量对板栗淀粉回生抑制作用与消化性能的影响
Effects of Oligofructose Addition on the Retrogradation Inhibition and Digestive Properties of Chestnut Starch
摘要
Abstract
To replace the high-calorie sucrose employed as a sweetener in the processing of chestnuts and further inhibit the retrogradation of chestnut starch,the effects of different addition amounts(10%-50%)of oligofructose on the gelatinize-tion,digestion and retrogradation properties of chestnut starch were investigated systematically by viscosity,gelatinization enthalpy value,resistant starch content,hardness,water distribution,short-range order,etc.,compared with the commonly used sucrose in processing.The results showed that after the addition of oligofructose the gelatinization temperature was significantly increased and the viscosity was significantly decreased(P＜0.05).Moreover,as the addition amounts increased,the swelling power,retrogradation value and gelatinization enthalpy value of chestnut starch gradually decreased by 21.4%,38.8%and 26.1%,respectively,compared with the original chestnut starch.Meanwhile,oligofructose could significantly increase the contents of slowly digestible starch and resistant starch(P＜0.05).During the storage at 4,℃,the addition of 50%oligofructose reduced the hardness,chewiness and R1055/1021 value of chestnut starch by 16.0%,23.2%and 37.1%,respectively,while enhancing the transparency and water-holding capacity,and decreasing the storage modulus.And oligofructose is more able to inhibit starch retrogradation than sucrose with the equal amount added.This study provides data support for using oligofructose to improve product quality,postpone starch retrogradation and develop new low-calorie chestnut products.关键词
