摘要：

The extraction condition of polysaccharides from apple with microwave was optimized through the single factor analysis and the orthogonal experiment. The optimum condition for extraction was that: the duration in microwave was 1.5 min; the ratio of apple pomace to liquid (g: ml) was 1: 10; microwave power was 200 w. The extraction rate of apple polysaccharides was 3.37% when extracted in the optimum condition. The solubility and viscosity of the extracted apple polysaccharides were also analyzed. It was found that the extracted apple polysaccharides were easily soluble in water and could not dissolve in ethanol, ether, or butanol. The viscosity of apple polysaccharides increased with the increment of its concentration, and highly linear relationship was found between them.
