An Experiment Study of Extracting Crude Protein from the Waste Residue of CV. Ventricousinternode Leaves

TONG Xiao-bin,XIE Yu,SONG Wei-jun(Department of Environment and Architectural Engineering,Wuyi University,Wuyishan,Fujian 354300,China)  
With waste residue of CV.Ventricousinternode leaves as raw material,the crude protein is obtained by alkali-extraction.By single factor experiment,the best extraction condition is defined as follows: the liquid and material ratio--8:1;the extraction time--60 min;pH=10;the extraction temperature--50℃.In the acid condition,the best pH of subsiding the protein is 4.0.With the micro-Kjeldahl′s method,the purified protein of the extractions obtained is 7.66%.The content of crude protein in the waste residue is 350mg per 100g bamboo dregs.The crude protein extraction ratio is 4.59%.The ingredients of the extraction are measured initially by FT-IR.
