The role of soybean phospholipids in aquafeed processing
Jul 28,2022
Soybean phospholipids have excellent physiological activity and surface activity, which is a kind of natural high-efficiency nutritional additives. Adding soybean phospholipids to feeds can play the role of emulsification, wetting, dispersion and surface activity, provide nutrition such as bile amine, phosphorus, inositol, choline and fatty acids, improve feed energy and nutritional value, increase feed conversion rate and reduce feed coefficient; improve palatability and have the effect of food attraction; help animals digest and absorb fats, oils and fat-soluble vitamins; protect the unsaturated acid in the feeds; promote the growth of animals and improve the survival of young animals, and improve the production of aquatic animals. Improve the survival rate of young animals and the production performance of aquatic animals; prevent fatty liver and enhance the resistance to disease; improve the physical quality and yield of pelleting; reduce the feed loss and energy consumption during extrusion molding; prevent dust flying and feed grading; reduce the dissolution loss of water-soluble nutrients in aquatic feed; improve the drift and sedimentation in aquatic feed and reduce the waste of feed and the pollution of water quality; and provide the unknown growth factors.
Role in aquafeed processing
1、Binder
Phospholipids added into compound feeds and premixes can play the role of bonding, reduce dust flying and automatic grading during feed processing, and maintain the effect of feed mixing uniformity.
2、Emulsifying stabilizer
Phospholipids have hydrophilic and lipophilic 2 groups in the molecule, so it is a very good fat emulsifier. Phospholipids can inhibit the loss of fat in the bait, increase the animal's absorption of fat, promote growth and improve the bait conversion rate. For young shrimp, can make up for the lack of bile caused by the reduction of fat digestion, prevent high mortality of young shrimp, improve the survival rate.
3, suspension
phospholipids not only emulsify the fat in the water and insoluble in water components also have a role. Phospholipids suspended in the emulsion of insoluble components to prevent the role of settling. Normally pelleted feed swells in water and tends to disperse and settle to the bottom, resulting in wasted feed and contaminated water. The use of a special phospholipid product suitable for fish and crustaceans can improve the abrasion resistance of pellet feed, enhance the cohesion of the feed in the water after expansion, thus improving the drift and settlement, which is conducive to the suspension of the feed in the water and convenient for fish and shrimp to eat.
4, lubrication
Phospholipids have good lubrication, which can reduce the loss of feed in the extrusion molding, reduce the wear and tear of feed on the equipment, and improve the pelleting yield and pellet quality. At the same time also reduces the consumption of energy in the pelleting process, and can make the product temperature rise to a minimum, so that this pellet can be quickly cooled down, the risk of mold is also reduced because of it, which is particularly important for bagged products.
5, liposome embedding agent
The use of phospholipid bilayer membrane properties, can be made to embed a variety of water-soluble and fat-soluble substances of liposomes. Therefore, the current processors use this feature of phospholipids, the feed buried made of particulate feed, specifically for feeding the open feeding period of fish fry, crustaceans and shellfish larvae. After the liposome embedded feed particles can be suspended in the water and maintain its stability, and it is easy for fish and shrimp and other larvae to swallow, and the nutrients in the feed are easy to be digested and absorbed.
