COEI-1-PRENZY Enzymatic preparations

The prescriptions described below concern all enzymatic preparations susceptible of being used during various operations that can be applied to grapes and their derivatives.

COEI-1-EPLEV Yeast protein extracts (YPE)

1. Object, origin and scope of application

The proteins of yeast protein extracts mainly come from the cytoplasm of Saccharomyces sp. yeast. These are separated by physical methods after an extraction process that limits their hydrolysis.

COEI-1-DIOSIL Colloidal silicon dioxide solution

Silica colloidalis solutio

Silicon gel in aqueous dispersion

1. Objective, origin and scope of application

Colloidal silicon dioxide solutions are aqueous dispersions of silicon dioxide particles which are hydroxylated on the surface and are, therefo

COEI-1-DIOCAR Carbon dioxide

Carbonic anhydride

Carbonei dioxydum

COEI-1-DMDC Dimethyl dicarbonate (DMDC)

Dimethyl pyrocarbonate

N° SIN = 242

C.A.S  004-525-33-1

COEI-1-DIATOM Diatomite

Keiselguhr

Terre silicea

1. Object, origin and field application

Diatomite is a sedimentary rock made up of siliceous shells (tests) of diatomite fossils (unicellular microscopic algae).

COEI-1-CUICIT Copper citrate x 2.5-hydrate

Copper citrate hemipentahydrate

COEI-1-CUISUL Copper sulfate, pentahhydrate

Copper (II) Sulfate, Pentahydrate

COEI-1-COLPOI Fish glue (Isinglass)

1. Objective, Origin and Scope of Application

Fish glue is made from the swim bladder, gills and ears of certain fish, notably sturgeon.

It is produced in the form of colorless or slightly yellowish transparent sheets or, most frequently, in ribbons which have the appearance of dry parchment, or in vermiculated or powder form.
