Embodiment Construction

[0013] 1. Preparation of fermented mash: Microorganisms are cultivated by strains, and after maturity, they are inserted into the first-level seed tank for cultivation. A mature fermented mash is obtained.

[0014] 2. Adsorption decolorization: The weight components of this composite decolorizer are as follows:

[0015] Powdered Activated Carbon, 2 parts,

[0016] activated clay, 1 part,

[0017] Sodium bentonite, 7 parts.

[0018] Put the mature fermented mash into the pretreatment tank, measure the volume of the fermented mash in the tank (the usage amount of the compound decolorizer, add 10 kilograms of the compound decolorizer by every 100 liters of fermented mash, calculate the powder activated carbon, activated clay and sodium-based bentonite), start stirring, and then add powdered activated carbon, activated clay and sodium-based bentonite in a stirring state, stir fully for 2 hours, and control the temperature of the mash to 36 degrees. After the decolorization tre...

Abstract

The invention discloses a method for producing a food grade enzyme preparation by using a compound decolorizing agent. The food grade enzyme preparation with high light transmittance, high purity and high transformation rate is obtained by performing strain culturing, first-stage seed culturing, second-stage seed culturing, fermenting, adsorption bleaching, primary filtering, secondary filtering,ultrafiltration concentration, preparation, enzyme activity adjustment, fine filtration degerming and impurity removing, analysis and detection, and filling; in a mash decolorizing process, adsorption bleaching is performed on fermenting mash by adopting a compound decolorizing agent; and the compound decolorizing agent consists of the following substances in parts by weight: 2-4 parts of powderyactive carbon, 1-2 parts of active argil and 5-7 parts of sodium bentonite. In the compound decolorizing agent, various components complement one another, so that adaptability to various components in a pigment can be realized, the filtering speed of a product can be increased, impurities and foreign enzymes are removed from a product, the purity of the product is increased, the service life of an ultrafiltration membrane can be prolonged, production cost is reduced, the color and luster of the product are improved, and the transparency of the product is enhanced.

Description

technical field [0001] The invention relates to the production of a food-grade enzyme preparation with high light transmittance, high purity and high conversion rate, that is, a method for producing a food-grade enzyme preparation by using a compound decolorizing agent. Background technique [0002] With the development of downstream industrial technology in the enzyme industry, higher requirements are placed on the quality of enzyme preparations. Enzyme is used as a food additive in the food industry. In addition to the internal quality requirement of enzyme activity, its external quality, such as: color, transparency, purity, viscosity, etc., has attracted more and more attention. As a result, higher requirements are placed on the quality of enzyme preparations. [0003] In order to solve the problem of deep color, poor light transmittance, and mixed enzymes in the enzyme preparation, we consulted a lot of information. In the food industry, the commonly used adsorbents i...
