preparation example Construction

[0040] A kind of preparation technology of producing isomaltulose, described preparation technology comprises the following steps:

[0041] Step 1, prepare mother liquor;

[0042] Step 2, preparing immobilized enzyme-producing bacteria;

[0043] Step 3, prepare crude enzyme liquid;

[0044] Step 4, isomaltulose mother liquor;

[0045] Step 5, preparing a finished product of isomaltulose with a purity greater than 95%.

[0046] Further, the parts by weight of the main components required to prepare the mother liquor are as follows: 15-30 parts of polyvinyl alcohol, 5-10 parts of sodium alginate, 5-10 parts of sodium methylcellulose (CMC), epoxy poly 4-8 parts of amine.

[0047] Raw materials used in the present invention: all are commercially available products.

[0048] Wherein the enzyme production medium takes 3-5% bean cake powder, 1-2% beef extract, 10-15% sucrose, and 78-86% water by weight percentage, mixes evenly, and sterilizes at a temperature of 115°C 30min to ...

Embodiment 1

[0051] A preparation process for producing isomaltulose, comprising the following steps:

[0052] Step 1. In parts by weight, take 15 parts of polyvinyl alcohol, 5 parts of sodium alginate, 5 parts of sodium methylcellulose, and 4 parts of epoxy polyamine, mix them evenly, and sterilize for 30 minutes at a temperature of 115°C. Cool to a temperature of 30°C to obtain the mother liquor for subsequent use;

Abstract

The invention relates to a preparation technology of isomaltulose, and specifically to a preparation technology for producing isomaltulose. The preparation technology comprises the following steps ofpreparing mother liquid, preparing immobilized enzyme-producing bacteria, preparing crude enzyme liquid and isomaltulose mother liquid, and preparing an isomaltulose finish product with the purity being greater 95%; the preparation technology for producing isomaltulose provided by the invention abandons the traditional technology of directly producing isomaltose through microbial fermentation (lowyield), produces sucrose isomerase through microbial immobilized fermentation, enables the sucrose isomerase to perform enzymolysis on sucrose in vitro, wherein the percent conversion reaches 95% orabove, the production cost is reduced, a product completely meets the newest international standards and Chinese national standards, and the production cycle is shortened.

Description

technical field [0001] The invention relates to a functional edible sugar, in particular to a preparation process for producing isomaltulose. Background technique [0002] Isomaltulose, white crystal, odorless, sweet, about 42% of sucrose, pure sweetness, isomaltulose, is an emerging functional edible sugar in the world in recent years, is an ideal substitute candy. The product has the advantages of low calorie, non-cariogenicity, high stability, high tolerance and non-hygroscopicity, especially that it does not cause blood sugar and insulin to rise after human consumption, and can increase the absorption and retention rate of calcium. Suitable for all people, especially for the elderly and children, diabetics, obese patients, dental caries patients, etc. It can be used as a food sweetener or excipient in the production and processing fields of various foods. [0003] Chinese patent application number: 200910114186.2, the name is the method of bio-enzymatic conversion of ...
