Abstract

The invention relates to the technical field of cane sugar making clarification, and particularly discloses a special compound enzyme preparation for sugar production. The special compound enzyme preparation comprises the following components in percentage by weight: 40-48% of dextranase, 18-25% of pectinase, 8-12% of cellulase, 4-6% of polyphenol oxidase, 4-6% of papain, 8-12% of magnesium chloride and 3-6% of poly dimethyl diallyl ammonium chloride. The invention also provides a preparation method of the special compound enzyme preparation for sugar production. A complex enzyme preparation is added to sugarcane squeezed juice for clarification treatment, the viscosity of sugar juice is obviously reduced, a certain viscosity reducing effect is achieved in the sugar boiling process, absorption and crystallization of sucrose molecules are facilitated, the color value of a finished product is reduced by 20-30%, the turbidity is reduced by 30% or above, water-insoluble impurities are reduced by 20-30%, the simple purity is improved, the sucrose recovery rate is increased, and waste molasses yield can be reduced.

Description

technical field [0001] The invention belongs to the technical field of sugar cane sugar clarification, and in particular relates to a special compound enzyme preparation for sugar production and its preparation method and application. Background technique [0002] In the production process of extracting sucrose from sugarcane, the main processes include pressing, clarifying, filtering, evaporating, boiling sugar and crystallizing, etc. The clarification process is essentially a process of removing impurities. In the entire sugar production process, the clarification process is a crucial one. important link. In addition to sucrose, the mixed juice sent from the pressing workshop also contains many other components, such as reducing sugars, polysaccharides, glucans, proteins, pectin, cellulose and pigments. In addition, there are quite a lot of bagasse chips and silt in the mixed juice, and the composition is quite complicated. The reducing sugar components in sugarcane juic...
