Optimization of acid method for microcrystalline cellulose from bean dregs

This paper researches optimization of the preparation of Microcrystalline Cellulose from Bean dregs,by employing the response surface analysis to study the effects of acid solution temperature,concentration and time on microcrystalline cellulose yield.The results show that interactions significantly affect microcrystalline cellulose yield,and that the regression equation provides the best technological conditions.The results indicated that acid solution temperature was 88 ℃ and time was 61 minutes,and concentration was 6%,the yield of microcrystalline cellulose was 69.5%.
