摘要：
Pectin was extracted from tobacco waste using two different extraction methods of conventional heat reflux extraction (HRE) and microwave-assisted extraction (MAE) respectively. The yield of pectin extracted by the two methods were studied rightfully. Then, the differences in the physicochemical properties of the pectins obtained by the two methods mentioned above were investigated. The results showed that, the two methods may result in different pectin structures, and which will further affect the properties of the pectin. Among them, the influence of microwave frequency on the structure and properties of pectin was particularly significant, excessive frequency always leads to a decrease in pectin properties.
