Problems solved by technology

Commercial enzymes are often a single enzyme or a compound enzyme composed of a single enzyme. This kind of solid enzyme produced by compounding not only has high production costs, but also has different production processes, conditions, and strains used for various enzymes. Differences, after compounding, it is inevitable that the activity of its component enzymes will be affected due to different conditions

preparation example Construction

[0019] The preparation method of the solid composite enzyme of the present invention comprises the following steps of preparing the solid composite enzyme for feed by flashing and drying the fermented koji material at low temperature, pulverizing and adding ingredients: 1. After flash drying at 80°C for 5 seconds, crush it into 40-mesh raw powder; 2. Add ingredients to the raw powder according to the formula to prepare the finished solid compound enzyme for feed; the ingredients are acid protease and α-amylase One or two, and corn bran powder; the mass percentage formula of each component is: raw powder: 4-12%, 50000U / g acid protease: 0 or 1-6%, 2000U / g α-starch Enzyme: 0 or 4-5%, corn bran powder: balance; 3. Pack and store the finished product.

[0020] The effective enzyme components of the solid fermented koji are xylanase, pectinase, mannanase, β-glucanase, cellulase, acid protease and α-galactosidase. Each of the following examples is implemented by applying the above-m...

Embodiment 1

[0024] According to the above-mentioned process, according to the formula listed in Table 1, 109kg of solid fermented koji material was flash-dried at a low temperature of 95°C and 80°C for 5 seconds to obtain 70kg of dry material, and pulverized by a pulverizer to obtain 70kg of 40-mesh raw powder. 70kg of 50000U / g acid protease and 1610kg of corn bran powder were used to obtain 1750kg of solid compound enzyme for pig corn and soybean meal type feed. It has been tested that it contains xylanase 45623u / g, pectinase 16918u / g, mannanase 821u / g, β-glucanase 36521u / g, cellulase 558u / g, acid protease 3765u / g, α-galactosidase 378u / g.

Embodiment 2

[0026] According to the above-mentioned process, according to the formula listed in Table 1, 109kg of solid fermented koji material was flash-dried at a low temperature of 95°C and 80°C for 5 seconds to obtain 70kg of dry material, and pulverized by a pulverizer to obtain 70kg of 40-mesh raw powder. 70kg of alpha-amylase of 2000U / g, 1610kg of corn bran powder, obtain the finished product of 1750kg of solid compound enzymes for poultry corn soybean meal type feed. It has been tested that it contains xylanase 45615u / g, pectinase 16887u / g, mannanase 818u / g, β-glucanase 36515u / g, cellulase 562u / g, acid protease 373u / g, α-galactosidase 368u / g, α-amylase 175u / g.

Abstract

A preparation method for a feeding solid complex enzyme comprises the following contents of: a. drying solid fermented materials by low temperature flash evaporation, and crashing the materials to prepare the raw powder; b. adding auxiliary ingredients to the raw powder according to the prescription to prepare the feeding solid complex enzyme; and c. packaging and storing the finished product. Inthe prescription, the auxiliary ingredients include acid protease, one or two types of alpha-amylases, and corn bran powder. The ratio of the components by weight is as follows: 4-12 percent of raw powder, 0 or 1-6 percent of 50000U/g acid protease, 0 or 4-5 percent of 2000U/g alpha-amylase, and the balance of corn bran powder. The solid complex enzyme prepared by the method has the advantages oflow cost, complete zymogram and high enzyme activity. Furthermore, the enzymes are mutually supplementary and dependent without antagonism.

Description

Technical field [0001] The invention relates to a preparation method of a solid compound enzyme for feed, in particular to a solid compound enzyme for feed prepared by applying the method. It belongs to the field of feed technology. Background technique [0002] The enzyme preparations currently added to the feed are all produced by microbial fermentation, and the conventional processes are: strain selection, fermentation culture, and enzyme extraction. Various enzymes also exist in animals and plants, but the cost of extracting enzymes from them is extremely high, and the production is limited by seasons. The use of microorganisms to produce enzyme preparations has high yields, low production costs, and is not subject to seasonal restrictions. [0003] The main feed enzyme varieties in the domestic and foreign markets include cellulase, amylase, β-glucanase, pectinase, protease, xylanase, etc. Commercial enzymes are often a single enzyme or a compound enzyme composed of ...
