What are lysolecithins?
For maximum efficiency, it is important to choose the best emulsifier. Emulsifiers like lysolecithins act as biosurfactants that are obtained by hydrolysing native lecithin derived from vegetable oils such as soybean oil. During the hydrolysation process, the phospholipids in native lecithin are hydrolysed by the natural enzyme ‘phospholipase A2’ into lysophospholipids, also called lysolecithins.
Whereas native lecithin is mostly used as a price-attractive source of energy in animal feed, lysolecithins are better known for their strong emulsifying capacity due to their amphiphilic nature, having both hydrophilic (water-soluble) and lipophilic (fat-soluble) characteristics. This amphiphilic nature enables water and fat to mix, thus supporting the action of bile salts through improved emulsification.
Lysolecithins are rapidly gaining popularity as these emulsifiers have proven their value as a cost-effective solution. Lysolecithins improve nutrient digestibility through better emulsification and increased enzymatic potential. They enhance nutrient absorption through improved mixed micelle formation and membrane permeability. Therefore, lysolecithins make it possible to reformulate feed by reducing energy and amino acid levels without reducing animal performance.
