Development of novel biocontrol encapsulation techniques for garlic extracts: first results

Abstract: The aim of the work presented here is to develop novel eco-efficient encapsulationtechniques for bioactive ingredients used in biological pest control for the EU projectINBIOSOIL. A process for production of small-scale alginate beads containing garlic extract byair atomization with self-constructed technical encapsulation equipment was developed. Theencapsulation protects the active ingredients against oxygen and other outside influences, thusenhancing shelf life and allows a slow release effect. The capsule size produced with thistechnology can be varied – depending on the desired product – between 4 and 600 μm. Particlesare stable and spherical.
