geniaBeads® CA - hydrogel beads from calcium alginate
Alginate is a biopolymer from seaweed which is very common in immobilization and encapsulation applications.
Due to its characteristic structure alginate solutions can be rapidly cured by action mainly of
bivalent ions. Most frequently calcium is used. The special curing gives the resulting hydrogel beads
a characteristic behaviour regarding conditions of pH, temperature, or contents of chelate forming agents or
special ions.
geniaLab® has a huge experience in working with alginates differing in their molecular size, viscosity
or molecular composition. We store a variety of alginate types from different suppliers to be able to react of
the individual demands of your application. We exclusively use certified quality alginates from leading
manufactures to guarantee controlled and consistent conditions for our products.
The hydrogel beads' size can be chosen from a wide range of 0.2 to 3 mm to give them the desired properties
regarding eye-appeal, release properties, or technical demands in general.

Pigmented calcium alginate beads
Hydrogel beads with pigments and colors that can add a special eye-appeal to your product.
We offer a variety of pigments, including pearlescent pigments, fluorescent pigments,
metallic pigments or interference pigments. |
|
Alginate beads with encapsulated powders
Hydrogel beads of various materials for incorporating high loadings of organic or
inorganic powders, e.g. mineral powders, metal oxids, or amino acids. The beads can be used in wet of dried
state. |
|
Alginate beads with oil
Various oils can be incorporated into alginate beads
at loadings of 5...30 %. These oils may also be or contain fragrances or flavors.
The beads might coated and dried also. |
|
Alginate beads for food application
Beads of various natural polymers incorporating flavours or
colorants to be added to food products. |
Pigmented calcium alginate beads
We produce hydrogel beads with a variety of different pigments for adding eye-appeal to your product.
Beads are available in various colors -

The size of the particles can be varied over a wide range of 0.2...3 mm to meet the requirements of
your application reagrding appearance and functionality.
Our pigmented calcium alginate beads are tested to be readily biodegradable according to OECD 301 B.

Alginate beads with encapsulated powders
By our JetCutter technology we are able to process polymer slurries that are higly loaded with
soluble or insoluble powdery material. Powders are mainly added to prevent dust, to have slow
release properties for soluble substances, to keep a spherical shape fo the beads after drying,
or to raise the density of the particles. Special applications like the production of milling beads
are also possible.
We successfully processed slurries with powder loadings of more than 30 or 40% - which means a very
efficient pay-load for your process.

Alginate beads with oil
The size of the particles can be varied over a wide range of 0.2...3 mm to meet the requirements of
your application regarding appearance and functionality. Oils can be incorprated at loadings
of about 5...30 % to the hydrogel matrix. Beads can be coated and also dried.

Alginate beads for food application
The size of the particles can be varied over a wide range of 0.2...3 mm to meet the requirements of
your application reagrding appearance and functionality. Addition of food-grade colorants, pigments,
or flavours is easily possible.
