Study on extraction process of banana polysaccharides
Purpose search for high-purity banana polysaccharide purification method.Methods:From mature bananas,heat extraction,ethanol alcohol,and then vacuum drying,to obtain banana polysaccharide,these banana polysaccharide were dissolved,CTAB precipitation solution,and finally obtained by vacuum drying of banana essence polysaccharide.Results:Extraction solvent was water,extracted twice number,water for the first was 12-fold,and the second was 8-fold,extraction time for the first was three hours,and the second was two hours,decompression filtrate concentrated to the original 50%,the concentration of ethanol precipitation was 70%,final concentration CTAB solution was 1.5%,decompression drying method for drying.Conclusion:Test results show that the high purity of the polysaccharides extracted from the banana to technology is feasible
