English

Subject field(s)
  • Biochemistry
  • Food Additives
  • Pulp Preparation (papermaking)
DEF

A type of polysaccharide found in plant cell walls in association with cellulose and lignin; it is soluble and extractable by dilute alkaline solutions.

CONT

The hemicellulose units are distinguished analytically from cellulose by the greater ease of hydrolysis in hot dilute acids and by solubility in aqueous alkaline solutions. Pulping and bleaching are normally done at conditions which maximize retention of hemicelluloses because they promote inter-fibre bonding and strengthen paper... The principal hemicelluloses are xylan in hardwoods and glucomannan in softwoods.

Domaine(s)
  • Biochimie
  • Additifs alimentaires
  • Préparation de la pâte à papier
DEF

Composé glucidique (gommes et mucilages, par exemple), hydrolysable en milieu acide, faisant partie de la membrane cellulaire des végétaux supérieurs. Sa solubilité en milieu alcalin la distingue des celluloses.

  • Aditivos alimentarios
  • Preparación de la pasta (fabricación de papel)
DEF

Cualquier carbohidrato de tipo celulósico, excepto la celulosa misma.

CONT

Junto con la pectina y la lignina, la hemicelulosa forma parte de la matriz de la pared celular.

OBS

Celulosa con un grado de polimerización de 150 o menos. Es un término colectivo para celulosas beta y gamma.

Record 2 2008-05-13

English

Subject field(s)
  • Fruits and Vegetables (Types and Processing - Food Ind.)
CONT

Fresh konjac is a type of tuber, similar to yam and taro, but oval in shape. The content of the main constituent, glucomannan, reaches its highest level after 3 years of growth.

French

Domaine(s)
  • Fruits et légumes (Types et traitement - Alimentation)
CONT

Le konjac est une plante d'Asie dont les tubercules sont utilisées afin de recueillir une fibre végétale appelée le glucomannane.

CONT

Le konjac est en fait un tubercule, et l'on extrait de ce tubercule une substance à la propriété étonnante ; en effet le glucomanane a la capacité d'absorber pas moins de 100 fois son volume d'eau, ce qui lui confère le pouvoir de former un gel volumineux et de grande viscosité dans l'estomac. Le gel que forme le konjac dans l'estomac n'est en aucun cas assimilé par l'organisme et n'apporte donc pas de calories.

Record 3 2003-01-31

English

Subject field(s)
  • Chemical Elements and Compounds
  • Biochemistry
  • Medication
DEF

A polysaccharide derived from the hydrolysis of hardwoods.

CONT

Glucomannan is high in fiber, essential for cleaning the digestive system. [It] is taken from the Konnyaku root and is from the same family as the yam, which is 100 percent natural dietary fiber without calories. Since lack of fiber is a major cause for the high incidence of growing gastrointestinal disorders, it is a valuable herb. It helps reduce cholesterol, helps maintain regularity and promotes bowel health. It helps to normalize blood sugar, to relieve stress on the pancreas and to discourage blood sugar abnormalities, such as hypoglycemia. [It] absorbs toxic substances produced during digestion and elimination. It binds toxic material and eliminates them before they can be absorbed into the blood stream. [It] acts as a prevention of chronic disease and a weight control agent. As a diet aid, it expands to about 50 times its original volume when used with a large glass of water.

French

Domaine(s)
  • Éléments et composés chimiques
  • Biochimie
  • Médicaments
DEF

Polysaccharide tiré du bois de feuillus.

CONT

[...] le glucomannane et le galactomannane (oligo- et polysaccharides) peuvent être très intéressants comme agents régulateurs de la digestion (mucilages) [...]

CONT

La gomme de konjac est un hydrocolloïde soluble dans l'eau obtenu à partir de la farine de konjac par extraction aqueuse. La farine de konjac est le produit brut non raffiné tiré de la racine de la plante pérenne Amorphophallus konjac. Le principal constituant de la gomme de konjac est le glucomannane, polysaccharide de poids moléculaire élevé soluble dans l'eau, composé d'unités de D-mannose et de D-glucose dans un rapport molaire de 1,6 pour 1, reliées par des liaisons glycosidiques en ß(1-4).
