Extraction of Pectin from Pomelo Peel
The extraction of pectin from pomelo peel was optimized to maximize pectin yield Y in this study. A central composite design of response surface methodology involving extracting time, extracting temperature, liquid-solid ratio and pH was used, and second-order model for Y was employed to generate the response surfaces. The optimum condition for Y was determined as follows: extracting time 1h, extracting temperature 95 °C, liquid-solid ratio 25, pH 1. Under the optimum condition, the pectin yield was 20.98%.
