Enzyme preparation and application and method of enzyme preparation for extracting ginger oleoresin

The invention provides an enzyme preparation and application and a method of the enzyme preparation for extracting ginger oleoresin and belongs to the field of application of enzyme preparations. The technical scheme includes that the enzyme preparation comprises the following components including, by weight, 1-10 parts of xylanase, 1-5 parts of glucoamylase and 1-5 parts of pectinase. The invention further provides application of the enzyme preparation for extracting ginger oleoresin and provides specific operating steps. With extraction rate of gingerol as the index, the fact that the extraction rate of gingerol is over 3% is finally achieved, and compared with the extraction rate of gingerol in an ethanol solvent soaking extraction method, the enzyme preparation enables the extraction rate of gingerol to be improved by over 30%. The enzyme preparation and the application and the method of the enzyme preparation for extracting ginger oleoresin have the advantages that reaction conditions are mild, conformat
