Abstract:

TakingmarketavailableAmaranthusmangostanusL.asmatarial,throughsingleandorthogonalexperiments,theeffectsofpHvaluesoftheextractingsolvents,pulpingtime,solid-liquidratio,soakingtimeontheextractionofleafproteinwerestudied.Onthebasisofthese,theinfluenceoffloccutationtemperatureandpHvaluesoftheextractingsolventsonprecipitationofleafproteinwerealsodiscussed. TheresultsshowedthattheoptimalextractingconditionswerepHvaluesoftheextractingsolvents5,pulpingtime5minutes,solid-liquidratio1∶7,soakingtime6minutes,manwhileflocculationtemperature85℃,pHvaluesofextractingsolventswere3and9.Undertheseconditions,theextractionrateofLPCreached2.90%andtheyieldratewas23.69%.
