PURPOSE: An aqueous low molecular polysaccharide and oligosaccharide thereof are provided which can be used in medicines, food-additive, cosmetic, natural pesticide, and etc.. CONSTITUTION: The low molecular polysaccharide and oligosaccharide thereof are produced by a process comprising the steps of: dispersing the polysaccharide such as pectin, chitin, chitosan, alginic acid, cellulose, and etc. in solvent such as pure water, and acetic acid; and adding a mixture of ozone/oxygen to the dispersed solution, wherein an amount of the ozone is 0.01-10 mole (based on the glucose amine of 1 mole).
