Abstract

Abstract: Take Polyrhachis viciua roger as raw material.the effect of different factors on extraction of ant protein with single factor test was investigated .The results showed that the optimum conditions were as follows:the ratio of solid/liquid was 1 to 20.the PH was 8.0 the salt concentration in the extractive reagent was 1%.the temperature was 25℃ and the time of extraction was two hours.The protein extract waw precipitated at PH4.5 and 4℃ for 2h .Using this technique .the protein extraction rate was 58.9% and the content of protein recovery was 81 .6%

Key words: Ant, Protein, Insect, Extraction
