Optimization of Clarification Process of Persimmon Vinegar by Response Surface Methodology

摘要

the clarification process of persimmon vinegar was optimized to maximize the transmittance in this study. A Box Benhnken design of response surface methodology involving addition amount of chitosan,temperature,time was used,and second-order model for the transmittance was employed to generate the response surface. The optimum condition for the clarification process was determined as follows: addition amount of chitosan 0.014 %,temperature 42 ℃,time 3 h. The obtained transmittance at the optimum condition was 87.8 %.
