Method for preparing a feed additive and the feed additive prepared thereby

By encapsulating fat-soluble vitamins in a matrix formed from lignin sulfonates and compounds, the problem of easy oxidation of fat-soluble vitamins in feed is solved, resulting in a stable feed additive with low processing loss, and avoiding the use of controversial additives.

AI Technical Summary

Technical Problem

Fat-soluble vitamins are easily oxidized in animal feed and are not water-soluble. Existing water-dispersible formulations have insufficient stability and suffer from high processing losses.

Method used

The matrix is ​​formed by lignin sulfonate and specific compounds to encapsulate fat-soluble vitamins, forming an oil-in-water dispersion. It is also coated with an absorbent to avoid the use of ethoxyquin and butylated hydroxytoluene, thus ensuring stability and safety.

Benefits of technology

It significantly reduces the oxidation and degradation of fat-soluble vitamins, with processing losses of ≤7%, provides a stable feed additive, and is not dependent on animal-derived compounds.
