| Abstract: | The content of starch and protein in tubers of Cyperus esculentus was determined by the iodine-vapor staining method and coomassie brilliant blue staining method,respectively.Results showed that the content of starch was 31.8%,that of protein was 2.9%.Using the limewater extraction method,the starch and protein from chufa tubers were extracted.Through the individual factor test and orthogonal design test,some factors,such as the limewater pH value,the ratio of sample to solution(W:V),the immersion time,the ... |
