Corn Steep Liquor Powder Aquatic Feed Ingredients

1，Introduction

Corn Steep Liquor Powder(CSL-Powder) is a pure non-GMO corn extract which is an excellent substitute for soybean meal and fish meal. CSL-Powder is a qualified plant-based feed ingredient with 43% of protein mainly in form of bioactive small peptides and free amino acids, lactic acid 24%, trace elements and biotin. It contains very few anti-nutritional compounds, such as aflatoxin, phytate acid, and trypsin inhibitor.

Corn Steep Liquor Powder is widely used as aquatic feed ingredient for fish feed,shrimp feed, crap feed or lobster feed. And it can improve the enzyme activity, feed digestibility and growth performance of aquatic organisms. Most importantly,Corn Steep Liquor Powder is much more cost effective than other protein nutrients.

Corn Steep Liquor powder can be used as a natural and safe pond organic fertilizer. Its rich amino acids, peptides, sugars and a variety of trace elements can promote the growth and reproduction of planktonic algae and beneficial microorganisms in the pond, which could provide natural bait for aquatic animals

2，Composition analysis

3，The effect of product

（1）Advanced production technology allows protein to be well preserved, which is conducive to improving feed digestibility.

When proteins are exposed to high temperatures, their amino acid structure changes. In practice, it will reduce the digestibility of feed. Different from the traditional processing technology, CSL-powder is a low-temperature spray-dried powder solid, therefore,the finished product has no coking phenomenon, and the active ingredients is well preserved.This is the key point to maintain high digestibility of aquatic feed.

And 43% plant derived soluble protein, mainly in the form of bioactive small peptides and free amino acids. It can be directly absorbed through intestinal mucosa, save energy and greatly improve the utilization rate of feed protein.

（2）CSL-powder contains very few anti-nutritional compounds and does not prevent aquatic organisms from absorbing plant proteins.

A plant-based protein source exploitation as an alternative ingredient of fish diet frequently obstructed by the antinutritional compound. An excessive level of the antinutritional compound will directly affect nutrient intake and digestibility,In contrast, it has greater advantages over other plant protein sources such as soybean meal.

（3）CSL-powder contains a lower level of acid detergent fiber (ADF), neutral detergent fiber (NDF), and crude fiber compared to the Soybean meal.

Crude fiber is still needed, although it is hardly digested. The low level of crude fiber increased peristaltic movement, thus the digestion process and chemical degradation rate of the diet increased as well.

（4）lactic acid content can improve enzyme activity.

The effect of adding CSL-powder to feed on pH of feed, stomach and intestinal tract was related to the presence of lactic acid in CSL-powder.Lactic acid improves the acidic environment in the stomach of aquatic organisms, and pepsin activity increases.The enzyme activity in the digestive tract is an indicator of digestibility and the ability to utilize the nutrient in the feed, therefore, lactic acid in CSL-powder, ultimately improve the utilization rate of aquatic feed. And lactic acid can replace antibiotics to reduce disease and enhance immunity

（5）Increase the fertility of water in the pond

Increase the content of organic matter in water, promote the reproduction of algae and beneficial microorganisms, enhance the vitality of aquatic animals, improve feed utilization and accelerate growth.

4，Our advantages

(1) CSL-powder is much cheaper than other sources of protein such as Fish meal and soybean meal.

(2) ISO Certificated,100% plant source

(3) It is a very fine yellow powder, so it is easy to transport,store and use.Meanwhile, it is not easy to deteriorate under dry conditions,and composition of CSL powder is stable and uniform.

(4)Developed by a professional team in cooperation with Chinese universities.
