Composite stabilizer for preservation of liquid cellulase

Abstract

The invention discloses a composite stabilizing agent for preserving a liquid cellulase, which can preserve the vitality of the cellulase for a long time under the liquid condition. The composite stabilizing agent is prepared from the raw materials including sucrose, sodium chloride, potassium sorbate and sodium hyposulfite by blending and stirring. The weight percentages of the raw materials in the liquid cellulase are as follows: 30 to 50 percent of the sucrose, 5 to15 percent of the sodium chloride, 0.01 to 0.03 percent of the potassium sorbate and 0.01 to 0.02 percent of the sodium hyposulfite. The composite stabilizing agent uses the sucrose and the sodium chloride so that cellulase protein molecules keep the stable structures easily in water molecules and are not easy to denaturalize and lose the activity, uses the potassium sorbate to control the colony count so as to meet the requirements on food conditions conveniently, and uses the sodium hyposulfite for preventing enzyme protein from being oxidized to lose the activity. The four raw materials of the composite stabilizing agent is easily available, the food grade is relatively high so that the cellulase activity cannot be reduced within two years at room temperature, the cost for building a refrigerated storage for keeping the cellulase activity is saved, and the preservation and transportation of the liquid cellulase are convenient.

Description

Technical field [0001] The present invention relates to a stabilizer for maintaining the activity of liquid cellulase enzyme. Background technique [0002] The application of cellulase in feed can supplement the deficiency of endogenous enzymes in herbivorous animals, eliminate anti-nutritional factors, maintain the integrity of the villi in the small intestine, promote the absorption of nutrients, and increase the weight of livestock and poultry. Application in textiles can make the surface of linen fabrics smooth, significantly improve the elasticity, drape and feel, basically eliminate the itching sensation to people, and increase the linen textile count by 20%; cellulase is used in cotton fabrics Finishing: Enzyme washing can eliminate cotton balls on the surface of the fabric, making the surface of the fabric even, smooth, shiny, clear in texture, and soft to the touch. Applying cellulase to fruit and vegetable juices and pollen drinks can increase the extraction rate ...
