Embodiment 1

[0040] Sodium gluconate production new method, concrete steps are as follows:

[0041] (1) Adjust the concentration and pH value of the qualified starch milk according to the process requirements, adjust the raw water to control the starch milk Baume degree 16-20, pH 5.3-5.8, add enzyme preparation in proportion, and the dosage of enzyme preparation is 0.5 Kg / T dry base starch, fully stir, and described enzyme preparation is aspergillus niger;

[0042] (2) Put the material obtained in step (1) into the injector, and the injection temperature is controlled at 105-115°C. The material is kept in the pipeline for 60-65 seconds, then enters the liquefaction tank, and keeps the temperature in the liquefaction tank at 80-85°C 30-35 minutes, the obtained material is liquefied liquid;

[0043] (3) Adjust the pH value of the liquefaction solution to 4.3-4.5; the temperature is 60-62°C, add glucoamylase according to the weight of dry starch, the dosage of glucoamylase is 0.45Kg / T dry st...

Embodiment 2

[0053] In step (1), the dosage of the enzyme preparation is 0.4Kg / T dry base starch, that is, 0.4kg enzyme preparation per ton of dry base starch.

[0054] In step (3), the amount of glucoamylase used is 0.55Kg / T dry base starch.

[0055] In step (7), the dosage of activated carbon is 2.0% of the weight of dry matter in the fermentation broth.

[0056] All the other technical features are the same as in Embodiment 1.

Embodiment 3

[0058] In step (1), the dosage of the enzyme preparation is 0.6Kg / T dry basis starch, that is, 0.6kg enzyme preparation per ton of dry basis starch.

[0059] In step (3), the amount of glucoamylase used is 0.38Kg / T dry base starch.

[0060] In step (7), the dosage of activated carbon is 4.0% of the weight of dry matter in the fermentation broth.

[0061] All the other technical features are the same as in Embodiment 1.

Abstract

The invention belongs to the technical field of sodium gluconate production and concretely relates to a novel production method of sodium gluconate. A biological fermentation method and a two-enzyme method are combined by process optimization, and through use of advantages of the methods, a sodium gluconate single tank capacity is improved and good market competitiveness is obtained.

Description

technical field [0001] The invention belongs to the technical field of producing sodium gluconate, in particular to a new method for producing sodium gluconate. Background technique [0002] At present, sodium gluconate mainly uses five methods: biological fermentation method, homogeneous chemical oxidation method, electrolytic oxidation method, catalytic oxidation method and oxidase method. The first four methods have been studied in our country, and the main ones currently used in production It is a biological fermentation method and a homogeneous chemical oxidation method, among which the biological fermentation method is the most widely used. [0003] Aspergillus niger is mostly used in the production of sodium gluconate by biological fermentation. The method is to add a small amount of nutrients such as magnesium sulfate and potassium dihydrogen phosphate to 250-320g / l glucose syrup, and after sterilizing at 110°C for 30 minutes, wait for After the culture medium is co...
