| Abstract: | Effects of extracting solvent concentration,temperature,time and solid-liquid ratio on extraction yield of purple corn anthocyanin were investigated.On the condition of single factor experiment,the extraction technique parameters were optimized with orthogonal experiment design and optimal extracting technique parameters of purple corn anthocyanin were determined as follows: 20 %HCl-ethanol as extracting solvent,temperature 70 ℃,time 8 h,and meanwhile the solid-liquid ratio 1∶10(g/mL). |
