Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a chitosan material having the principal properties of chitosan as a material for a functional drink, keeping the stability and solubility in neutral and alkaline range, expectable to prevent lifestyle-related diseases and aging and develop a cosmetic effect and having improved taste. SOLUTION: The chitosan material having improved taste is composed of a water-soluble chitosan having a weight-average molecular weight of 3,000-7,000 and exhibiting antioxidation action and immunity activity. The water-soluble chitosan preferably has a specific molecular weight distribution containing ≥40% oligosaccharide component having a molecular weight of ≤2,000 and
