The present disclosure relates to a method of producing lactic acid bacteria dual-coated with protein and polysaccharide by using a protein hydrolysate, and lactic acid bacteria having a dual coating, produced by the method. The lactic acid bacteria having a dual coating of protein and polysaccharide, produced according to the present disclosure, have very excellent dry-freezing viability, acid resistance and bile resistance. Accordingly, the lactic acid bacteria having a dual coating of protein and polysaccharide according to the present disclosure will be very useful for the production of fermented milk, processed milk, fermented soy products, processed foods, functional beverages, functional foods, common foods, etc.
