titleOfInvention | Preparation method of galactomannan oligosaccharide |
abstract | The invention provides a preparation method of galactomannan-oligosaccharide, which takes guar gum as a substrate, firstly, the guar gum is compounded and degraded by using hydrogen peroxide and ascorbic acid, then, the hydrogen peroxide remained in a catalase removal system is utilized, commercial acid β -mannase is added for enzymolysis, hydrolysate is inactivated, centrifugal impurity removal is carried out, after concentration, high molecular weight carbohydrate is removed by using 3-5 times of ethanol precipitation, ethanol precipitation supernatant is suspended and evaporated to be concentrated until the content of solid is not less than 20%, GMOS dry powder with the molecular weight of less than 10000Da is prepared by spray drying, and wet granulation is carried out on the GMOS dry powder by using 80-95% ethanol, so that solid particles with good 40-100 meshes of dissolubility can be obtained. |
