Potato Extract is a light yellow to yellowish-brown fine powder prepared from fresh high-quality potatoes through advanced modern production technology. The production process includes cleaning, crushing, low-temperature leaching, coarse filtration, fine purification, vacuum concentration and spray drying, which effectively retains the natural active components in potatoes while ensuring product stability and solubility.

In terms of fermentation application principles, potato extract is rich in carbohydrates, vitamins, minerals, small molecular organic acids and a variety of growth-promoting factors. It can provide sufficient carbon sources and auxiliary nutrients for microorganisms, regulate the osmotic pressure of the culture medium, optimize the microbial growth environment, and promote cell proliferation and metabolic activity.

It is widely used in microbial culture, industrial fermentation, vaccine preparation and biological product research. When used together with peptone, yeast extract and other nitrogen sources, it can significantly improve the growth density of strains and the synthesis efficiency of target products, and is an ideal natural component for preparing various culture media.
