Optimization of preparation of calcium propionate from eggshell by Response Surface Methodology (RSM)
| Resumo: | Abstract Response surface methodology (RSM) was used to investigate the preparation-process parameters on calcium propionate from eggshell. Box-Behnken was used for experimental design and the optimal combination of the preparation-process parameters for preparing calcium propionate was analyzed. Multiple regression analysis was used to fit the experimental data to the second-order polynomial equation, and appropriate statistical methods were used for analysis. The results show that optimum preparation conditions of calcium propionate were as follows: reaction temperature of 85 °C, solid-liquid ratio of 1:16, propionic acid concentration 176.00%, ultrasonic power of 135 W, ultrasonic time of 1.4 min, primary reaction time of 1.0 h and second reaction time 64.00 min. Under the optimum preparation conditions, the experimental yield of calcium propionate was 96.12%, which was in good agreement with the predicted value. |
