| Abstract: | The effect of ultrasonic method on the process of extraction polysaccharide from apples was studied. Based on the result of single factor test, the orthogonal test of the ultrasonic extraction of polysaccharides from apples was designed. The optimum extraction conditions were proposed. The extracting time was 25min, the ratio of apple powder to alcohol was 1：125, the extracting temperature was 45℃ and the concentration of alcohol was 50%. Under the optimum extraction conditions the ratio of the polysaccharide extraction was over 55%. |
