Record 1 2026-03-27

English

Subject field(s)
  • Nutritive Elements (Biological Sciences)
  • Dietetics
CONT

Antioxidants obtained from vegetables and fruits are mostly of phenolic structure, which may include vitamins, minerals, and polyphenols. Antioxidant minerals, such as iron, zinc, selenium, copper, and manganese, act as cofactor of many antioxidant enzymes, absence of which may certainly disturb the activity of their enzymatic scavenging activity.

OBS

antioxidant: A substance that inhibits oxidation, especially one ... that protects cells from the sometimes damaging effects of oxidation.

Key term(s)
  • anti-oxidant mineral
  • mineral anti-oxidant

French

Domaine(s)
  • Éléments nutritifs (Sciences biologiques)
  • Diététique
OBS

Le zinc et le sélénium sont des exemples de minéraux antioxydants.

OBS

antioxydant : Substance chimique qui retarde ou empêche le processus d'oxydation.

Subject field(s)
  • Medication
  • Dietetics
  • Food Industries
CONT

Green tea extract contains antioxidant compounds, including flavonoids, vitamins and polyphenols such as epigallocatechin-3-gallate(EGCG), which may have antineoplastic properties.

CONT

Green tea extract can be consumed in capsule, liquid, or powder form.

French

Domaine(s)
  • Médicaments
  • Diététique
  • Industrie de l'alimentation
CONT

Le principal antioxydant présent dans le thé vert est l'EGCG [gallate d'épigallocatéchine]. Les produits de santé naturels contenant de l'extrait de thé vert sont vendus sous diverses formes posologiques, telles que des capsules, comprimés, des poudres et des liquides, à prendre par voie orale (par la bouche).

English

Subject field(s)
  • Chemical Engineering
  • Wood Products
DEF

A type of lignocellulosics fractionation based on an organosolvolytic approach.

CONT

Thermomechanical organosolvolytic treatment(TM-S). This technology was inspired by the classical organosolvolytic approaches aiming at delignification... Using a combination of variables(the solubility parameters of the chosen solvent, temperature, reaction time, and shear through homogenizing valves), the hemicelluloses and lignin are solubilised while the cellulose remains as residue. The subsequent separation of the hemicelluloses and lignin can be accomplished by classical chemical engineering techniques, although associations between the polyphenols(lignin) and carbohydrates(hemicelluloses) can interfere during the separation process.

French

Domaine(s)
  • Génie chimique
  • Produits du bois
DEF

Procédé de fractionnement des matières lignocellulosiques utilisant une approche organo-solvolytique.

CONT

Traitement thermomécanique en phase organique (TM-S). Cette technologie s'inspire des approches organo-solvolytiques classiques visant la délignification [...] Par une combinaison des paramètres de solubilité du solvant choisi, de la température, du temps de réaction, ainsi que du cisaillement (par la détente flash) à travers les vannes d'homogénéisation, nous pouvons solubiliser les hémicelluloses et la lignine, alors que la cellulose reste comme résidu. La séparation subséquente des hémicelluloses et de la lignine peut s'accomplir par des techniques classiques de génie chimique, bien que des associations entre les polyphénols (lignine) et les glucides (hémicelluloses) puissent interférer lors de la séparation.

Key term(s)
