Foam separation for protein of Catharsius molossus / 中草药

ABSTRACT

Objective To optimize the technique of foam separation from extract of Catharsius molossus.Methods Single factor test was used to examine the key operational parameters by using enrichment ratio,recovery rate,and protein content as the evaluation indexes.Results The best conditions were as follow airflow velocity,feed concentration,pH value,feed volume,and temperature were 600 mL/min,0.050 g/mL,pH 4,1 000 mL,and room temperature,respectively.Under the condition,the enrichment ratio was 1.56,recovery rate was 85.6%,and protein content was 20.37%.Conclusion Foam separation could be used to concentrate and separate protein from extract of C.molossus with higher recovery rate and protein content.
