A new corn fiber gum polysaccharide isolation process that preserves functional components

► Process developed to isolate corn fiber gum preserving its functional components (protein, phenolic acids and lipids). ► Low alkali concentration and short incubation time preserves a maximum percent of protein and phenolic acids on corn fiber gum. ► Corn fiber gum isolated from wet milling endosperm fiber contains higher amount of protein than corn fiber gum isolated from wet milling pericarp fiber.
