SHREDDED-MEAT-SHAPED PET FOOD AND PREPARATION METHOD THEREOF

Abstract

The present invention discloses a shredded-meat-shaped pet food which consists of the following raw materials in percentage by mass: 65 to 95% of plant-based protein, 0 to 20% of starch, 0 to 15% of animal raw materials, 1 to 7% of vegetables, 1 to 5% of fruits, 0.5 to 3% of beer yeast, 0.02 to 0.05% of potassium sorbate, 0.1 to 0.7% of salt, 0.3 to 0.5% of essences, 0.01 to 0.05% of phosphate and 0.02 to 0.03% of mixed vitamins. According to the technical solution of the present invention, the plant-based protein, meat, vegetables and fruits are prepared into the shredded-meat-shaped pet food by a mechanical puffing extrusion technology. The shredded-meat-shaped pet food in the technical solution of the present invention is a product having a fibrous shredded-meat shape, and thus has a very good sensory effect and palatability effect. As more and more people keep pets, such shredded-meat-shaped pet food has a broad development prospect and needs to be developed urgently to fill the market gap.
