Isomaltulose is generally regarded as an "ideal substitute" for sucrose, and has extremely broad application prospects in the food, chemical and pharmaceutical fields
.
At present, the industrial production of isomaltulose is mainly obtained from sucrose catalyzed by sucrose isomerase, which causes the cost of isomaltulose to directly depend on the cost of raw material sucrose

The researchers introduced sucrose isomerase-related genes from Pantoea dispersa UQ68J into E.
coli to construct a cell factory to efficiently catalyze the conversion of untreated sugar cane molasses into isomaltulose
.
The calcium alginate system was used to immobilize the recombinant E.

At the same time, in vitro studies have shown that isomaltulose can promote the growth of a variety of probiotics, including Lactobacillus casei, Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus acidophilus, Bifidobacterium animalis, Bifidobacterium longum, Bifidobacterium breve Bacillus and Bacillus coagulans
.
This shows that isomaltulose has a prebiotic effect

This research provides a theoretical basis for low-cost production of isomaltulose and promotion of its industrial application as a prebiotic
