COEI-1-NANMEM Nanofiltration membranes

1. Object, origin and scope of application

Membranes belonging to the family of semi-permeable membranes, these can be homogenous or composite membranes and are generally organic; they may have a spiralled or "spiral-wound", flat sheet or "frame and plate", tubular or hollow fibre configuration.

COEI-1-MEMULT Ultrafiltration membranes

1. Object, origin and scope of application

Membranes belonging to the family of porous membranes, these can be organic or inorganic, and are generally anisotropic (asymmetric) or composite membranes; they may have a spiralled or "spiral-wound", flat sheet or "frame and plate", tubular or hollow fibre configuration.

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.

COEI-1-MEMOSM Reverse osmosis membranes

1. Objective, origin and scope of application

A reverse osmosis membrane is a membrane belonging to the group of semi-permeable thin-layer composites (known as TFC, or Thin Film Composites).

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.

COEI-1-MANPRO Yeast mannoproteins

1. Object, origin and field of application

Mannoproteins are extracted from Saccharomyces spp. or non-Saccharomyces yeast cell walls by physico-chemical of enzymatic methods.

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.

COEI-1-LTARAC L(+) Tartaric acid

L-2,3-dihydroxybutanedioic acid

Dextrorotatory tartaric acid

Acidum tartaricum

COOH - CHOH - CHOH - COOH

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

1. Object, origin and field of application

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

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. or non-Saccharomyces yeast biomass.
