DIETARY FIBER, ITS PROCESS AND PHYSIOLOGICALLY ACTIVE COMPOSITION CONTAINING THE SAME AS AN ACTIVE INGREDIENT

摘要

The present invention discloses the dietary fiber which is extracted from abran with an aqueous solvent at 170 to 220°C, containing, as its principalingredient, a water soluble and hardly digestible polysaccharides rich in .beta.-glucose, being novel distinct from a conventional dietary fiber which is producedby extraction of a bran with an aqueous solvent at a temperature below 170°C,having tumor growth inhibiting activity, Lactobacillus bifidus proliferatingactivity, cholesterol metabolism improving activity and immunologic responseenhancing activity, being quite safe to animals as well as to humans, which canbe beneficial when utilized as an active component of a pharmaceuticalcomposition or a dietary composition, and a manufacturing method of suchdietary fiber and the physiological active substances utilizing such dietary fiber.
