How to use enzymatic hydrolysis technology to improve the digestibility and absorption rate of fish meal?

Enzymatic hydrolysis technology is a technology widely used in food, feed, medicine and other fields. It can improve the digestibility and absorption rate of fish meal, thereby improving its nutritional value. Enzymatic hydrolysis technology is a process that uses the decomposition of enzymes to decompose macromolecules into small molecules. In terms of improving the digestibility and absorption rate of fish meal, enzymatic hydrolysis technology can be achieved in the following ways:
1. Reduce the fiber content in fish meal. The fiber content in fish meal is high and is not easily digested and absorbed by animals. By adding enzyme preparations such as cellulase, the fiber in fish meal can be decomposed into small molecules such as soluble sugars and amino acids, thereby reducing the fiber content in fish meal and improving its digestibility and absorption rate.
2. Decompose the protein in fish meal. The protein content in fish meal is high, but its structure is complex and is not easily digested and absorbed by animals. By adding enzyme preparations such as protease, the protein in fish meal can be decomposed into small molecules such as peptides and amino acids, thereby reducing the protein content in fish meal and improving its digestibility and absorption rate.

In order to better utilize enzymatic hydrolysis technology to improve the digestibility and absorption rate of fish meal, the following points should be noted:
1. Select appropriate enzyme preparations
Different enzyme preparations have different mechanisms of action and effects, so it is necessary to select appropriate enzyme preparations according to specific circumstances. For example, for fish meal with a high fiber content, cellulase can be used to reduce its fiber content; for fish meal with a high protein content, protease can be used to decompose its protein.
2. Control appropriate enzymatic hydrolysis conditions
The conditions of enzymatic hydrolysis technology are very important, including temperature, pH value, moisture content, etc. Changes in these conditions will affect the activity and effect of the enzyme, so it is necessary to control appropriate enzymatic hydrolysis conditions according to specific circumstances. For example, during the enzymatic hydrolysis process, it is necessary to control the appropriate temperature and pH value to ensure the activity and effect of the enzyme.
3. Combined with process technology
In order to better improve the digestibility and absorption rate of fish meal, it can be combined with other process technologies. For example, fish meal can be puffed or ultrafinely crushed to increase its surface area and fluidity; fish meal can be mixed with an appropriate amount of enzyme preparations such as flavor enzymes to improve its nutritional value.
