MEMBRANES DE NANOFILTRATION
COEI-1-NANMEM Nanofiltration membranes
- 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.
MEMBRANES D’ULTRAFILTRATION
COEI-1-MEMULT Ultrafiltration membranes
- 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.
MEMBRANES BIPOLAIRES D’ELECTRODYALISE
COEI-1-MEMBIP Bipolar electrodialysis membranes
- 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.
MEMBRANES D’OSMOSE INVERSE
COEI-1-MEMOSM Reverse osmosis membranes
- 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).
MEMBRANES D’ELECTRODIALYSE
COEI-1-MEMELE Electrodialysis membranes
- 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)
- Object, origin and field of application
Lysozyme (Chlorhydrate and Lysozyme) is an edible egg white extract from hens.
L(+) TARTRIQUE (ACIDE)
COEI-1-LTARAC L(+) Tartaric acid
L-2,3-dihydroxybutanedioic acid
Dextrorotatory tartaric acid
Acidum tartaricum
COOH - CHOH - CHOH - COOH
LEVURES ENVELOPPES CELLULAIRES (ECORCES)
COEI-1-YEHULL Cellular yeast hulls (Yeast walls)
- 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.
LEVURES AUTOLYSATS
COEI-1-AUTLYS Yeasts autolysates
- 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.
LEVURES INACTIVEES (GLUTATHION)
COEI-1-LEVGLU Inactivated yeasts with guaranteed glutathione levels
- 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.
