English

Subject field(s)
  • Processing of Mineral Products
  • Mineral Processing (Metallurgy)
  • Chemical Engineering
CONT

Flotation modifiers include several classes of chemicals as described below. ... Alkalinity regulators such as lime, caustic soda, soda ash, and sulfuric acid are used to control or adjust pH, a very critical factor in many flotation separations.

OBS

pH regulators: Substances used in flotation processes to control the hydrogen-ion concentration.

Key term(s)
  • pH regulating agent
  • pH modifying agent

French

Domaine(s)
  • Préparation des produits miniers
  • Minéralurgie (Métallurgie)
  • Génie chimique
DEF

Réactif utilisé pour amener le pH de la pulpe à une valeur choisie.

English

Subject field(s)
  • Food Additives
  • Food Industries
CONT

Starch modifying agents are used to chemically change one or more of the characteristics which govern the properties of starch. [Starches] with high temperature stability are required for heat sterilized products. Similarly, starches must withstand severe mechanical agitation and pH variation. By using a starch modifying agent the starch manufacturer is able to tailor his product to the application in question and to maintain the palatability and appearance of the foods.

OBS

The term "starch modifier" is used to define "1-octenyl succinic anhydride".

French

Domaine(s)
  • Additifs alimentaires
  • Industrie de l'alimentation
CONT

Les agents modificateurs de l'amidon sont utilisés dans le but de modifier chimiquement une ou plusieurs des caractéristiques qui influent sur les propriétés de l'amidon [...] L'utilisation d'agents modificateurs de l'amidon permet de changer certaines caractéristiques du produit en fonction de l'utilisation qu'on en fait et de maintenir les caractères organoleptiques des produits finis.

Record 3 2010-03-01

English

Subject field(s)
  • Food Additives
DEF

A food additive used to improve the appearance or feel of a food.

CONT

For instance, canned tomatoes, canned potatoes and canned apple slices tend to become soft and fall apart, unless the texturizer calcium chloride, for example, or its salts are added, which keep the product firm.

Key term(s)
  • texturiser
  • texturising agent

French

Domaine(s)
  • Additifs alimentaires
DEF

Substance naturelle ou d'origine chimique, qui permet ou facilite le maintien en équilibre de phases physiques hétérogènes présentes dans une préparation alimentaire.

OBS

Par leurs propriétés émulsifiantes et stabilisantes, ces additifs confèrent une onctuosité ou une gélification à une denrée alimentaire prête à l'emploi.

Record 4 2006-02-28

English

Subject field(s)
  • Processing of Mineral Products
  • Mineral Processing (Metallurgy)
  • Chemical Engineering
DEF

In flotation, chemicals which increase the specific attraction between collector agents and particle surfaces, or conversely which increase the wettability of those surfaces.

CONT

Modifying Agents. The chemical and physical additives discussed in this section are variously described in flotation literature as regulators, conditioners or more specifically as depressants, activators, wetting agents, flocculants and dispersants. The practical requirement from the operator's viewpoint is the ability of the additive to sharpen selectivity as between the mineral species floated and that (or those) left in the pulp. ... The regulating chemicals used in flotation stimulate the desired surface activity of specific minerals in the pulp. Modifying agents therefore either reinforce or make possible the adsorption of collectors in the case of floating species, or aid hydration if they are active depressants.

French

Domaine(s)
  • Préparation des produits miniers
  • Minéralurgie (Métallurgie)
  • Génie chimique
OBS

modificateur (adj): Qui a la propriété de modifier. Agent modificateur.

OBS

Modifier: Changer (une chose) sans en altérer la nature, l'essence.

OBS

[L]'état de surface des corps n'est pas forcément identique à leur état interne: les surfaces sont en général modifiées par action chimique ou adsorption.

OBS

Les sources spécialisées consultées ne traitent que des types spécifiques d'agents modificateurs, par exemple les dépresseurs, les activants, et les régulateurs. C'est pourquoi il n'est pas certain que les équivalents français donnés soient utilisés dans le domaine du traitement des minerais.
