Levulose group fermentation raw material and uses thereof

Abstract

The invention relates to a fructosyl fermented raw material and the application, 1) an inulin-rich organ of an inulin plant is dried, smashed into powder by a smashing machine, screened by 50 to 200 meshes and produced into powder; 2) the powder is dissolved by water at 45 to 70 DEG C to be made into the solution with a weight concentration of 10 to 20 percent, an inulin powder enzymolysis reaction liquid is prepared according to the proportion of each liter solution added with 1000U to 100000U units of inulinase, the pH value is regulated to 4.2 to 6.5, the reaction is carried out in a reactor at 45 DEG C to 70 DEG C for 3 to 9 hours, a fructose inulin powder liquid is formed after the enzymolysis reaction, or the fructose inulin powder is prepared by further spray drying. The production cost is low, the sources of the raw material are wide, the technique is simple, the technical route is mature and the industrial implementation can be realized.

Description

technical field [0001] The invention relates to a fructose-based fermentation raw material prepared from inulin plants as a fermentation substrate instead of starch fermentation raw materials such as corn starch, which is applied to the production process of food, fuel, chemicals, materials and biological preparations in the fermentation industry. Background technique [0002] Starch is the most simple and easy-to-obtain glucose-based raw material, and it is also very easy for microorganisms to use. At present, my country's starch is mainly made from corn. However, due to the limited area of ​​cultivated land in my country, my country produces 120 million tons of corn annually, which is less than half of that of the United States. The per capita share is less than 100 kilograms, and the consumption of breeding accounts for 70-80%. The corn used for industry accounts for 10% of the total corn production. About, only more than 10 million tons per year, therefore, the domestic ...

However, due to the limited area of ​​cultivated land in my country, my country produces 120 million tons of corn annually, which is less than half of that of the United States. The per capita share is less than 100 kilograms, and the consumption of breeding accounts for 70-80%. The corn used for industry accounts for 10% of the total corn production. About 10 million tons per year, therefore, the domestic cornstarch is far from being able to meet the development of large-scale fermentation industry
