How to store corn steep powder in summer?

In hot summer conditions, the storage of Corn Steep Liquor Powder (CSLP) presents significant challenges.

Due to its rich content of organic matter such as nitrogen compounds, sugars, and active microorganisms, improper storage can lead to the rapid growth of bacteria and other microbes, resulting in souring and product deterioration. In addition, the liquid form of Corn Steep Liquor contains uneven internal materials that tend to precipitate, making storage management even more troublesome.Organic Fertilizer Corn Steep Liquor Powder 42

In high-temperature environments, Corn Steep Liquor need stored in low-temperature facilities  Without proper cooling, the product is highly susceptible to bacterial contamination and spoilage. Even sealing with corn oil is not always effective, as some CSLP may still deteriorate. Cold storage requires round-the-clock operation, and since many enterprises demand CSLP in large volumes, this leads to the need for high-capacity cold storage—resulting in significantly increased costs. Therefore, companies that use CSLP extensively often seek storage methods that don't require such stringent conditions in order to reduce expenses.

CSLP can naturally produce lactic acid by metabolizing carbohydrates, which lowers the product's pH and inhibits the growth of pathogenic microorganisms. These naturally formed antibacterial agents can act as food preservatives and also help break down nitrites, reducing the formation of harmful ammonium nitrite.

In the microbial fermentation industry, CSLP is a valuable nitrogen source used in fermentation media. Compared to other high-cost nitrogen additives, it is relatively economical due to its production via high-temperature spray drying of corn steep liquor. It boasts high nitrogen content and is also rich in amino acids, vitamins, soluble proteins, and inorganic salts—making it widely applicable in microbial fermentation and culture processes.NPK  Fertilizer corn steep liquor powder 42%
