Bipolar electrodialysis membranes

COEI-1-MEMBIP Bipolar electrodialysis membranes

  1. Object, origin and scope of application

A bipolar membrane is a thin, dense, insoluble wall composed of a polymer material functionalized by ionic groups. A bipolar membrane has an anionic face and a cationic face; it is equivalent to combining a cationic membrane and an anionic membrane into a single membrane.

Electrodialysis membranes

COEI-1-MEMELE Electrodialysis membranes

  1. Objective, Origin and Scope of Application

An electrodialysis membrane is a thin, dense, insoluble wall composed of a polymer material that is permeable to ions.  When placed between two solutions, it allows the selective transfer of ions from one solution to the other when acted upon by an electric field.

Lysozyme

COEI-1-LYSOZY Lysozyme

Muramidase

N°SIN: 1105 (enzyme 3.2.1.17)

  1. Object, origin and field of application

Lysozyme (Chlorhydrate and Lysozyme) is an edible egg white extract from hens. It is used to inhibit bacterial growth and can be used in musts and wine. Doses are limited in level.

Yeast hulls

COEI-1-YEHULL Cellular yeast hulls (Yeast walls)

  1. Object, origin and field of application

The cellular yeast hulls are obtained from Saccharomyces spp. yeasts. The preparation mode must respect the surface area and consequently the adsorption capacity.

Yeast autolysates

COEI-1-AUTLYS Yeasts autolysates

  1. Object, origin and scope of application

Yeast autolysates are used as nutrients during the rehydration of dry active yeasts intended for alcoholic fermentation, and also as nutrients during alcoholic fermentation. Yeast autolysates are derived from Saccharomyces spp. yeast biomass.

Inactivated yeasts (glutathion)

COEI-1-LEVGLU Inactivated yeasts with guaranteed glutathione levels

  1. Object, origin and scope of application

These inactivated dry yeasts (IDY) with guaranteed glutathione levels are characterised by higher levels of reduced glutathione than those contained in standard inactivated yeasts. They are used to limit oxidation phenomena in musts and wines.

Inactivated yeasts

COEI-1-INAYEA Inactivated yeasts

  1. Object, origin and scope of application

Inactivated yeasts are used as nutrients for yeasts at the beginning of and during alcoholic fermentation, and also to encourage the rehydration of active dry yeasts.
