Disclosed herein is a process for preparing a carbohydrate extract comprising mannoheptulose from avocados, as well as compositions, including food compositions, comprising such extracts. The process includes separating the aqueous emulsion into different fractions by centrifugation, and isolating the water-soluble fraction (water extract) comprising avocado carbohydrates, including mannoheptulose. In various aspects, the process optionally includes steps of heating, ultrafiltration, nanofiltration, concentrating, and or drying the extract. Also described herein are methods for using the carbohydrate extract comprising mannoheptulose and compositions comprising the carbohydrate extract comprising mannoheptulose. L'invention concerne un procédé de préparation d'un extrait glucidique comprenant du mannoheptulose provenant d'avocats, ainsi que des compositions, notamment des compositions alimentaires, comprenant de tels extraits. Le procédé comprend les étapes consistant à séparer l'émulsion aqueuse en différentes fractions par centrifugation, et à isoler la fraction soluble dans l'eau (extrait aqueux) comprenant des glucides d'avocat, y compris du mannoheptulose. Selon divers aspects, le procédé comprend éventuellement des étapes de chauffage, ultrafiltration, nanofiltration, concentration et/ou séchage de l'extrait. L'invention concerne également des méthodes d'utilisation de l'extrait glucidique comprenant du mannoheptulose et des compositions comprenant l'extrait glucidique comprenant du mannoheptulose.
