On August 4-6, the 11th International Exhibition of Biological Fermentation Products and Technology Equipment was held at the Shanghai New International Expo Center. This is a highly anticipated event in the biological fermentation industry in China. As the main exhibitor, Zhengguang conducts technical exchanges with customers on-site.

Fermentation can be used to produce various food additives such as tartaric acid, citric acid, lactic acid, glutamic acid, serine, etc. Ion exchange resins and macroporous adsorption resins have exchange and adsorption characteristics, making them good medium for extraction and separation.

Zhengguang D314FD, J-18, D630, and D315 are all acrylic based macroporous weakly basic anion exchange resins. Due to their specific pore structure and active groups, as acrylic based resins, they have advantages such as high exchange capacity, fast exchange rate, high resolution, and strong anti-pollution ability. They have good adsorption properties for aldehydes in both aqueous and non-aqueous solutions. Mainly used for removing anions such as chloride and sulfate in the production of organic acids such as tartaric acid, citric acid, lactic acid, succinic acid, etc.

Zhengguang C108-L, 001 × 7FD and D001 are food grade specialized strong acidic styrene based cation exchange resins that have been disinfected and sterilized through special processes. Especially suitable for the extraction and desalination of food fermentation industries such as starch sugar, tartaric acid, beer, sorbitol, xylitol, amino acids, citric acid, and lactic acid.

Zhengguang SD300, SD720, SD750, SD730 and other macroporous adsorption resins are suitable for decolorization and impurity removal of fermentation broth. They have advantages such as high decolorization efficiency, large adsorption capacity, high elution rate, and good mechanical strength, and can replace activated carbon for decolorization of feed liquid. The regeneration process is simple and reduces operating costs.

Zhengguang SPC106H, SPC106K, SPC106Na, SPC106Ca chromatography cation resin, and SPA412 chromatography anion resin can be used for the separation of various similar substances. They have the advantages of high separation purity, high yield, low water consumption, good mechanical strength, good permeability resistance, and superior performance.

The pace of upgrading and increasing production capacity in China's biological fermentation industry is constantly accelerating, and ion exchange and adsorption resins will have a wider application in the fermentation field. Zhengguang will continue to focus on its main business, closely focus on customers’ needs, enhance the company's technological advantages, bring higher quality products and more professional services, and create value for customers.
