| Abstract: | Objective To study the extraction and content determination of pectin from Cerasus tomentosa,and to investigate the effects of different conditions on the extraction of pectin.Method Pectin was prepared by acid hydrolysis ethanol precipitation method,and the extraction process of pectin from Cerasus tomentosa was optimized by orthogonal design (L933). The content of pectin was determined by carbazole colorimetry. Results The optimum processing conditions were as follows:solid-to-liquid ratio of 1:6,extraction temperature of 90oC and extraction time of 2 h.The content of pectin in Cerasus tomentosa was 4.613%.Conclusion It is feasible to extract pectin from Cerasus tomentosa. |
