Embodiment 1

[0018] Such as figure 1 Shown, a kind of preparation method of corn maltose syrup, concrete operation steps are as follows:

[0019] a. Slurry liquefaction: mix the raw material cornstarch with water to make the cornstarch content reach 34%, add high-temperature-resistant amylase under the condition of pH5.6, and then liquefy at 108°C for 3 minutes to obtain a liquefied slurry;

[0020] b. Spray laminar flow: spray the liquefied slurry prepared in step a once at a temperature of 95°C for 90 minutes, and control the DE value to 15%; then continue to carry out secondary spraying at the same temperature for 30 minutes, control The DE value is 16% and the slag is removed and filtered to obtain the spray slurry;

[0021] c. Saccharification: Saccharify the sprayed slurry prepared in step b and the compound glucoamylase at 60°C and pH 4.5 for 4 hours to obtain the saccharified slurry; remove slag after saccharification; the compound glucoamylase is fungal enzyme, β-amylase , pullu...

Embodiment 2

[0026] Such as figure 1 Shown, a kind of preparation method of corn maltose syrup, concrete operation steps are as follows:

[0027] a. Slurry liquefaction: mix the raw material cornstarch with water to make the cornstarch content reach 40%, add high-temperature-resistant amylase under the condition of pH5.8, and then liquefy at 110°C for 5min to obtain the liquefied slurry;

[0028] b. Spray laminar flow: spray the liquefied slurry prepared in step a once at a temperature of 98°C for 120 minutes, and control the DE value to 20%; then continue to carry out secondary spraying at the same temperature for 30 minutes, control The DE value is 22% and the slag is removed and filtered to obtain the spray slurry;

[0029] c. Saccharification: saccharify the jet slurry prepared in step b and the compound glucoamylase at 62°C and pH 6.0 for 120 hours to obtain the saccharification slurry; remove slag after saccharification; the compound glucoamylase is fungal enzyme, β-amylase , pullu...

Embodiment 3

[0034] Such as figure 1 Shown, a kind of preparation method of corn maltose syrup, concrete operation steps are as follows:

[0035] a. Slurry liquefaction: mix the raw material cornstarch with water to reach a cornstarch content of 37%, add high-temperature-resistant amylase under the condition of pH5.7, and then liquefy at 109°C for 4 minutes to obtain a liquefied slurry;

[0036] b. Spray laminar flow: spray the liquefied slurry prepared in step a once at a temperature of 97°C for 100 minutes, and control the DE value to 18%; then continue to carry out secondary spraying at the same temperature for 30 minutes, control The DE value is 19% and the slag is removed and filtered to obtain the spray slurry;

[0037] c. Saccharification: saccharify the jet slurry prepared in step b and the compound glucoamylase at 61°C and pH 5.0 for 60 hours to obtain the saccharification slurry; remove slag after saccharification; the compound glucoamylase is fungal enzyme and β-amylase , pull...

Abstract

The invention relates to the field of corn deep processing, in particular to a preparation method of malt syrup prepared from corn, which specifically comprises the following six steps: syrup mixing and liquefying, laminar flow spraying, saccharifying, decolorizing, deodorizing, evaporating and concentrating. The method mainly overcomes the defects caused by using the deodorizing resin, and has the advantages that: 1, the deodorizing resin in the original process can be replaced to solve the odor of the product in the production by actually operating the method, the production cost and the purchase cost can be reduced, and by taking 150,000 tons of malt syrup per year as an example, the use amounts of hydrochloric acid, caustic soda liquid and water are reduced by 450 tons every day; the production cost is saved by 700000 yuan / year, meanwhile, the purchase cost of the deodorizing resin is reduced by 400000 yuan / year, and 2,the activated carbon in the method can be reused after decoloration, so that the cost investment in the later period is not increased.

Description

Technical field: [0001] The invention relates to the technical field of corn deep processing, in particular to a method for preparing corn malt syrup. Background technique: [0002] Northeast China is the main producing area of ​​corn. In the past two years, Heilongjiang has ranked first with an output of nearly 40 million tons. Corn contains a large amount of malt syrup, which is also widely used in the field of food processing. In the existing process of making malt syrup from corn, ion exchange resin is generally used in the decolorization process, but in actual production, the operation of ion exchange is cumbersome, the water consumption is large, the process cost is high, the composition of waste liquid is complex, and it is easy to cause environmental pollution. Invention content: [0003] The purpose of the present invention is to provide a method for preparing corn malt syrup in order to overcome the above-mentioned shortcomings in the prior art. [0004] A kind...
