Complex enzyme detergent for high-temperature-resisting cane sugar manufacturing industry as well as preparation and application thereof

Abstract

The invention discloses a complex enzyme detergent for a high-temperature-resisting cane sugar manufacturing industry as well as preparation and application thereof and belongs to the technical fieldof clarifying technologies of the sugar manufacturing industry. The complex enzyme detergent is prepared from the following components in percentage by weight: 20 to 50 percent of heat-resisting dextranase, 5 to 35 percent of high-temperature-resisting alpha-amylase, 5 to 25 percent of heat-resisting pectinase, 4 to 20 percent of high-temperature-resisting laccase, 3 to 20 percent of heat-resisting horseradish peroxidase, 3 to 20 percent of high-temperature-resisting cellulase and 0 to 10 percent of water. After raw material enzymes are mixed according to a ratio, a mixture is subjected to membrane filtration and is quantitatively filled to obtain a product. In a process from primary heating to secondary heating, the complex enzyme detergent is added into crude sugar juice to carry out clarification treatment. A complex enzyme preparation formed by a proper ratio prevents a condition that only one enzyme usually cannot reach a predicated impurity removal and clarification effect; a buffering stage does not need to be set, adding sites are wide and the limitation caused by temperature is relatively small.

Description

technical field [0001] The invention belongs to the technical field of clarification technology in the sugar industry, and in particular relates to a compound enzyme detergent for high-temperature-resistant sugarcane sugar industry and its preparation and application. Background technique [0002] The clarification methods commonly used in domestic sugar refining process are mainly through several ways: 1. Adding lime, phosphoric acid, PAM flocculant, SO2 or CO 2 Precipitation of chemical reagents; 2. Adsorption with activated carbon; 3. Ion exchange. These conventional clarification methods cannot effectively remove the influence caused by such high-viscosity polysaccharide components in sugarcane, the sugar-making material. [0003] At present, there have been researches on the use of compound enzyme preparations in sugar production. Through biological enzymatic action, the macromolecules and colloids that are harmful to sugar production in the raw materials and newly pro...
