11/09/2017: How to deliver plant-based compounds for maximum benefit to animals

by Carina Schieder, Biomin Holding GmbH, and Pia Gottschalk, Biomin Research Centre

As phytogenic feed additives (PFAs) become increasingly accepted by the feed and livestock industries, there is greater scrutiny as to whether products can fulfill the expected benefits

One key to success is product design that ensures the plant-based bioactive compounds are delivered where they are needed to be most effective, which requires the right formulation and encapsulation.

Biomin has developed a proprietary encapsulation technology for essential oils and phytogenic active compounds, the Biomin® Duplex Capsule, and an advanced formulation of Digestarom® DC, which represents a new approach to phytogenics, one that aims to provide a superior solution in animal feeds.

Why encapsulation matters
In the food and feed industry, encapsulation commonly serves to protect flavors from oxidation, to increase a product’s shelf life and to provide controlled release of substances over a period of time. While numerous phytogenic compounds are known to have benefits for feed and livestock, various phytogenic compounds exert different properties.

Essential oils and their active compounds in particular are highly volatile and heat sensitive—less than ideal characteristics in the context of modern feed production and pelleting. The challenge is to make sure that substances that have an insufficient shelf life, or be broken down in the digestive tract before they can exert their biological active properties on animals, are instead delivered where they are needed to have a positive effect.

Breakthrough encapsulation technology
To improve the applicability of essential oils and their active compounds in feed, Biomin developed a unique method of microencapsulation (a term for particles with a diameter between 1 and 1000 microns).

The Biomin® Duplex Capsule combines two encapsulation techniques —matrix and core-shell encapsulation. With core-shell encapsulation, a protective coat surrounds a core comprising essential oils and active compounds, providing better product stability and ensuring targeted release further along in the gastrointestinal tract.

In Digestarom® DC, the coat and core contain different essential oils for appetising and gut modulation modules, respectively. Both layers are matrix encapsulated, meaning that the active compounds are finely dispersed in a solidified matrix, which provides slow, controlled release.

Biomin proprietary encapsulation technology results in double capsules with a uniform and narrow size distribution ranging from 120 to 500 microns, allowing for more homogeneous distribution of active compounds in Digestarom® DC and eventually in the feed, meaning continuous delivery of active substances in the animals.

In addition, the particles have a very high essential oil content compared to other commercially available products. Furthermore, the Biomin® Duplex Capsule structure gives Digestarom® DC enhanced pelleting stability over 90°C.
