Protein extraction of the long-term room temperature storage wheat straw

摘要

Study on extract protein from long-term room temperature storage of wheat straw,utilize L _9(3~4) Orthogonal experiment on the basis of single factor test.Study the impact of extraction time,ext raction temperature and solid-liquid ratio on protein extraction yield of wheat straw.Result show fact ors affect wheat straw protein extraction rate in the order of extraction time>extraction temperature> liquid ratio>blank test,the optimal conditions is 50 °C, the solid-liquid ratio 1:20 extract for 12 hours. Measured extraction yield is 21.761%.
