Title
(EN) PROCESS FOR PRODUCING FRACTIONATED PECTIN PRODUCTS
(FR) PROCEDE DE FABRICATION DE PRODUITS DE PECTINE FRACTIONNEE
Abstract
(EN)
A process is described for producing fractionated pectin from vegetable source starting material. The process comprises a two-step extraction of the vegetable material by first contacting it with a weakly acidic solution at a temperature and for a time to sufficiently remove a non-calcium sensitive pectin (NCSP) fraction, separating the extract juice from the vegetable matter, and contacting the separated vegetable matter with a stronger acid solution at a temperature and for a time sufficient to remove a calcium sensitive pectin (CSP) fraction.
(FR)
Cette invention concerne un procédé de fabrication de pectine fractionnée à partir d'une matière de départ végétale. Le procédé fait intervenir l'extraction de matière végétale qui se déroule en deux étapes: la première étape consiste à mettre la matière végétale en contact avec une solution faiblement acide à une température et pour une durée permettant de prélever une fraction de pectine non sensible au calcium (PNSC), puis à séparer le jus extrait de la matière végétale; la seconde étape consiste à mettre la matière végétale ainsi séparée en contact avec une solution plus acide à une température et pour une durée permettant de prélever une fraction de pectine sensible au calcium (PSC).
