摘要
以红薯淀粉为原料,在糊化和未糊化条件下采用碱液分散法对原淀粉进行分级,对提纯后的直链淀粉样品进行了分析;采用除去蛋白质和脂类的原淀粉进行浸提,可以大大提高产物的纯度,产品的纯度用其碘络合物的紫外可见光扫描图谱进行了证实。同时测得红薯直链淀粉含量16.12%。
The detailed process of extraction of amylose was studied in the gelatinization and non- gelatinization temperatures from sweet potato native starch , and the extracted and purified amylose sample were analyzed ,it was well proved that deprotein and defatted starch should be used to obtain in amylose of high purity.The purity of amylose have been confirmed by UV-Vis scans of their complex formed with iodine. The amylose content is 16.12 % for the starch from the tuber of sweet potato.
