Application of Complex Plant Enzyme in the Production of Cottonseed Protein

Cottonseed protein oligopeptide was obtained from cottonseed meal using composite plant enzyme.The effects of crush size,temperature,extraction time on yield of cottonseed protein was investigated by single-factor test,and finally the optimum conditions for extracing cottonseed protein was determined as : particle size 60 mesh,enzyme dosage 0.5 %,reaction time 2 h.At these conditions,the protein conversion rate was 89 %,the final product content of protein was 93 % by dried.
