China Drying Network Recently, the National Agricultural Science and Technology Achievement Transformation Project undertaken by Hebei Province has successfully passed the acceptance test of the transparent xanthan gum technology for starch sugar and soybean biological method, and achieved four major technical breakthroughs such as low-temperature drying.
Transparent xanthan gum is a kind of bio-polysaccharide produced by special bio-fermentation engineering, which is based on agricultural products such as starch sugar and soybean powder, and it is a kind of safe food additive with special functions. It belongs to the national "Twelfth Five-Year Plan" strategic emerging industry. Focused support for biotechnology. The aqueous solution has the characteristics of high transparency, good thickening and suspending performance, and rheological pseudo-plastic controllability. It is a safe replacement thickening emulsification product for dairy products, fruit milk beverages, transparent beverages, condiments, jelly, juices, etc. in the food industry. The agent is a new generation of environmentally friendly and healthy stabilizers in the softeners, high-end cosmetics, toothpastes and personal care products of the daily chemical industry.
The project achieved four major breakthroughs in the R&D process. First, it screened xanthan gum producing bacteria that can use both inorganic nitrogen and organic nitrogen but was dominated by inorganic nitrogen. The pyruvic acid content was 2.6%; Membrane technology is combined to separate and purify the fermentation broth; the third is to pretreat the non-grain fermentation carbon source; and the fourth is to combine the low-pressure drying with low-pressure and low-temperature comminution to ensure the homogeneity of the polysaccharide molecular structure. "The method of post-extraction of transparent xanthan gum" and "Method of post-extraction of available xanthan gum" won the national invention patent.
During the implementation period of the project, a total of 550 tons of transparent xanthan gum was produced, with a sales income of 35.75 million yuan, a tax payment of 4.4 million yuan, a net profit of 7.31 million yuan, and foreign exchange earnings of 2.2 million US dollars.
