(ZH) 一种制备α-1,6-葡聚糖的方法
Abstract: front page image
(EN)Disclosed is a method for preparing an α-1,6-glucan, comprising the steps of: performing water extraction on banana pulp, concentrating the extract liquid, and performing ethanol precipitation to obtain crude banana polysaccharides; purifying the crude polysaccharides through an anion exchange resin, eluting same with water or a phosphate solution, concentrating and drying the water elution phase to give the α-1,6-glucan, and concentrating, dialyzing and drying the phosphate solution elution phase to give the α-1,6-glucan with a yield of 3-16 g/kg (a purity of 85-95%).
(FR)L'invention porte sur un procédé de préparation d'un alpha-1,6-glucane, comprenant les étapes consistant à : effectuer une extraction à l'eau de pulpe de banane, concentrer le liquide extrait et effectuer une précipitation à l'éthanol pour obtenir des polysaccharides de banane bruts ; purifier les polysaccharides bruts sur une résine échangeuse d'anions, en utilisant comme éluant de l'eau ou une solution de phosphate ; concentrer et sécher la phase d'élution aqueuse pour obtenir l'alpha-1,6-glucane ; et concentrer, dialyser et sécher la phase d'élution à la solution de phosphate pour obtenir l'alpha-1,6-glucane avec un rendement de 3 à 16 g/kg (une pureté de 85 à 95 %).
