The present invention provides a coating agent being applicable even in 100% water, not sticky, which results in the coated particles and/or granules that do not stick to each other, and further having a function to control dissolution time, and a film formed from the coating agent and useful as a packaging material having an extremely low oxygen permeability coefficient even under highly humid conditions. An oxygen-barrier property enhancer such as glucose, mannose, maltose, trehalose, fructose, arabinose, nigerooligosaccharide, lactose, D-glucono-1,5-lactone, arginine hydrochloride, ferrous sulfate, sodium dihydrogen phosphate, Palatinit, vitamin C, etc. is added to yeast cell wall fractions consisting of cell residue obtained by removing the internal soluble cell components of enzyme-treated yeast or acid-treated yeast cell wall fractions consisting of cell residue obtained by treating said fractions with an acidic aqueous solution. Thus, the coating agent is prepared. The oxygen permeability coefficient of the film formed from the coating agent is less than 0.1 at relative humidity of 60%. |
