摘    要:通过单因素实验及正交试验,确定碱法提取炒制裸燕麦淀粉的最佳工艺,并测定其理化特性.结果表明,炒制裸燕麦淀粉较佳提取条件是料液比为1:18,pH值为9.5,提取温度为50℃,提取时间为60min.在此条件下,炒制裸燕麦淀粉提取率可达57.54%.理化特性研究表明,炒制裸燕麦淀粉中直链淀粉含量、蓝值及糊化温度均低于未炒制裸燕麦淀粉.

关 键 词:炒制裸燕麦  淀粉  提取  理化特性

Abstract:The optimum extraction conditions of drying roasting naked oat starch were obtained by single-factor experiment and orthogonal experiment as follows,material-water ratio 1:18,pH value 9.5,extraction temperature 50℃ and extraction time 60min.Under these conditions,the extraction rate could amount to 57.54%.At the same time,physical and chemical properties of dry roasting naked oat starch were determined.The results showed that amylose content,blue value and gelatinization temperature of the starch decreased.
Keywords:dry roasting naked oat  starch  extraction  physicochemical properties
