PROBLEM TO BE SOLVED: To obtain the subject polysaccharide that fits to social interests of environmental protection and safety and is widely useful in industry, by hydrolyzing a polysaccharide extracted from the plant body cell wall of a specific plant with a specified enzyme. ;SOLUTION: The cell walls of a plat in Festuca of Gramineae, for example, barley, is extracted with an aqueous alkali, for example, sodium hydroxide and the fraction is treated with an enzyme preparation having the xylanhydrolyzing enzyme activity (for example, Trichloderma viride) to form the objective water-soluble polysaccharide. As the cell wall, the filtration residue prepared by germinating the seeds of the plant, subjecting the germinating seeds to saccharification treatment, filtering the product, preferably used. The extraction is carried out by, for example, adding an alkaline aqueous solution of 0.05-2N concentration to the starting substance in an amount of 1-10,000 pts.wt. per 1 pt.wt. of the starting substance at 20-120°C for 3 minutes to 48 hours. The polysaccharide has a weight ratio of xylose/arabinose of 2.1/1-1.9/1 and mainly comprises arabinoxylan with a weight - average molecular weight of 1-1,000,000. As oil to be emulsified, fat and oil, for example, soybean oil is used.;COPYRIGHT: (C)1998,JPO
