Compound stabilizer for liquid ocean dextranase and application of compound stabilizer

The invention provides a compound stabilizer for liquid ocean dextranase. The compound stabilizer for the liquid ocean dextranase comprises, by weight, 3-24 parts of sodium acetate, 10-26 parts of sodium citrate, 6-16 parts of glycerinum, and 0.02-0.07 part of p-hydroxybenzoic acid. After the stabilizer is added into the liquid dextranase and the liquid dextranase is kept for four months at the temperature of 4 DEG C, the relative enzyme activity of the dextranase can be kept above 85%. The compound stabilizer for the liquid dextranase is scientific in compatibility, obvious in stabilizing effect, low in cost, capable of maintaining high enzyme activity of the liquid dextranase, and strong in stability, thereby being an efficient stabilizer for the liquid dextranase and being significant for industrialization development of ocean dextranase liquid preparations.
