The present invention relates to a pet food manufacturing method utilizing the protease, its manufacturing method is rice, oats, chicken minutes, sorghum, barley, beet pulp, whey protein, salmon, cheese, egg powder, vitamin / mineral premix and a first step of mixing into the glycerin in a blender; The rice, oats, chicken minutes, sorghum, barley, beet pulp, whey protein, salmon, cheese, egg powder, vitamin / mineral premix, glycerin grinding the mixed material to a size of 80 mesh, and for 65 seconds at 85 ℃ temperature a second step of steaming; A third step of the grinding is by extrusion (Extrusion) steaming the material at 120 ℃ temperature and so that the shaping and bulking, cutting the bulking material to the feed size of the pet; And a fourth step of bulking by the addition of the palatability-enhancing agent composition prepared by hydrolysis with a protease protease coating material to a predetermined size through the cutting step; ; And the water content by drying the doped material palatability enhancer composition at 20 ℃ temperature for 30 minutes, a fifth step such that, and packaging and to cool the dried pet food is 7-11% or 18-20% It characterized in that it comprises.
Yiettara, the present invention provides an effect to improve the palatability of the product to provide the food with a predetermined amount of water was added to the hydrolysis of animal raw material decomposition by a protease in the pet food.
