(FR) GEL IONOTROPE DEFICIENT EN ENTITE IONIQUE DE GELIFICATION, PROCEDE DE PREPARATION D'UN TEL GEL ET UTILISATION DE CELUI-CI NOTAMMENT DANS UN PROCEDE D'ELABORATION DE VIN EFFERVESCENT
Abstract
(EN)
Ionotropic gel forming, in particular, a fermentation biocatalyst. The gel, chiefly in the form of spheres, is prepared from an ionic gel-forming material by means of an ionic gelling entity and is characterized in that said gel lacks a gelling ionic entity, thereby exhibiting an affinity for ions, especially cations, such as the calcium ion and potassium ion. According to an advantageous embodiment, the gel contains yeast cells or cells of fermentative micro-organisms. The invention is advantageous in a process for gelling wine froth, especially champagne, in order to avoid crystalline precipitation and diminish turbidity in the sparkling wines obtained. It is also advantageous in processes for the removal of heavy metals, enzymatic or detection processes and fixing or purifying organic materials such as proteins or amino acids.

L'invention concerne un gel ionotrope formant notamment biocatalyseur de fermentation. Ce gel, en particulier sous forme de billes, est préparé à partir d'un matériau ioniquement gélifiable au moyen d'une entité ionique de gélification, et caractérisé en ce que ledit gel est déficient en entité ionique de gélification, présentant ainsi une affinité pour les ions, en particulier les cations, tels que l'ion calcium, l'ion potassium. Selon une réalisation avantageuse, ce gel contient des cellules de levures ou de micro-organismes de fermentation. L'invention est avantageuse dans le cadre du procédé de prise de mousse du vin, en particulier du vin de champagne, pour éviter les précipitations cristallines et diminuer la turbidité des vins effervescents obtenus, ainsi que dans le cadre des procédés d'élimination des métaux lourds, des procédés enzymatiques ou de reconnaissance, fixation ou purification de matériaux organiques, comme des protéines ou des acides aminés.
