Novel k-carrageenan and k-carrageenan-alginate beads
Encapsulator B-390: Vegetal alternative to alginate beads
Alginate and carrageenan are biocompatible polymers abundant in nature that could be used as matrix material for gel beads. These novel beads may serve for a wide variety of applications, such as enzyme immobilization.Aim of this application is to produce k-carrageenan as well as k-carrageenan-alginate beads with the Encapsulator B-390. The Encapsulator B-390 is a laboratory instrument applied in chemistry, pharmaceutical, food and biotechnology field to produce spherical and homogeneous beads.

Freeze drying of beads containing yeasts
The cell viabilities of microorganisms during storage are of economic importance for probiotic dietary food and feed supplements. By combining granulation and freeze drying, dust free particles homogeneous in size and composition can be obtained. This will enable a good particle flowability, an easier dosage and a faster reconstitution of the product can be obtained. Encapsulator as a granulator to prill the yeasts suspension into liquid nitrogen and form monodispersed beads that will then be freeze dried.
