Steeping is a procedure used during wet corn milling. The major objectives for corn steeping are to induce chemical and physical changes in the kernel by leaching the soluble components from the corn. Cleaned shelled corn is soaked for 30-48 hours at 120 - 130° F in a dilute sulfur dioxide solution. The steeped liquid is then separated from the non-soluble corn solids, which are further separated into germ, bran, starch, and gluten protein. The steeped liquor is concentrated by evaporation into Condensed Corn Fermented Extractives or Corn Steep Liquor (CSL).
Corn steep liquor is a mixture of soluble protein, amino acids, carbohydrates, organic acids (e.g., lactic acid), vitamins, and minerals.
●Corn steep liquor, with its rich nutrients profile, is a great organic fertilizer/organic nutritional aid for organic agriculture, and is available at a much cheaper price point than other organic fertilizers. Since the corn steep liquor is a by product of the corn wet milling industry, and is hing in nutritional content, it is the perfect contender for an organic fertilizer. Apart from its rich nutrient profile, the benefit that corn steep liquor has over other chemical fertilizer is the readily-available nitrogen content to be absorbed by the plants. Free nitrogen content, coupled with a rich amino acid profile of corn steep liquor makes for a highly suitable organic fertilizer for organic agricultural practices.
●It is also used as a nutrient for microorganisms in the production of enzymes, antibiotics and other fermentation products. It is sometimes combined with other ingredients in corn gluten feed and widely used in complete feeds for dairy and beef cattle, poultry, swine and pet foods. It may also be sold separately as a liquid protein source for beef or dairy rations.
●In addition to the above purposes, corn syrup can also be used for biological fermentation, aquatic feed, sewage treatment, etc.

Packaging & Shipping:
This kind of liquid bag is commonly used in transportation. A liquid bag is about 20 tons of corn steep liquor. It is very convenient for transportation or loading and unloading.
We are a factory, we supply high quality corn steep liquor all year round.
