摘要
[目的]优化马铃薯淀粉提取方法.[方法]以鲜马铃薯为原料,采用直接烘干法、水提取法和溶剂提取法3种方法进行提取,测定不同样品中水分、色泽、支链淀粉、直链淀粉含量.[结果]采用溶剂提取法(1.0％氯化钠溶液∶0.2％亚硫酸钠溶液=1∶1)得到的淀粉各项指标最优,水分含量7.62％,颜色白,粉质细腻.[结论]该研究可为我国马铃薯的加工利用提供依据.
Abstract
[Objective] The fresh potato was used to optimize the extraction method of potato starch.[Method] Direct drying method,water extraction method and solvent extraction method was used to extract the samples.Water content,colour,amylopectin content,and amylose content was analyzed.[Result] The results showed that solvent extraction method (1.0％ sodium chloride solution:0.2％ Sodium sulfite solution =1:1) was a good method to extract potato starch which had good property.[Conclusion] This research will give some advice to the potato industry.
