Title (EN) REFINED BETA-GLUCANS AND METHODS OF MAINTAINING FILTERABILITY OF BETA-GLUCAN COMPOSITIONS AT VARIOUS SALINITIES
(FR) BÊTA-GLUCANES RAFFINÉS ET PROCÉDÉS DE MAINTIEN DE LA FILTRABILITÉ DES COMPOSITIONS DE BÊTA-GLUCANE À DIVERSES SALINITÉS
Abstract:
(EN) Various aspects relate to refined beta-glucans and methods of maintaining filterability of compositions including beta-glucans at various salinities. A refined beta-glucan forms an aqueous beta-glucan composition including 1 g/L of the refined beta-glucan, the aqueous beta-glucan composition having a salinity of 100,000 ppm TDS or less and having a Filterability Ratio of less than 2 at a temperature of at least 50 ºC.
(FR) Selon divers aspects, la présente invention concerne des bêta-glucanes raffinés et des procédés de maintien de la filtrabilité des compositions comprenant des bêta-glucanes à diverses salinités. Un bêta-glucane raffiné forme une composition aqueuse de bêta-glucane comprenant 1 g/L de bêta-glucane raffiné, où la composition aqueuse de bêta-glucane a une salinité en termes de TDS de 100 000 ppm ou moins et un taux de filtrabilité inférieur à 2 à une température d'au moins 50 °C.
