To extract pets, most people's idea is still to keep the single old for emotional and psychological needs, but with the improvement of the mass living materials, the white-collar people living in the city, sandwiched in the middle of the social class, have become a new and huge support team. It is understood that there are more than 100 million pets in China, the number of pets in China has increased five times in the past 10 years, and the domestic pet consumption market has exceeded 40 billion yuan in 2010. It can be seen that the pet industry is rapidly growing into an important part of the urban economy in China. With the rapid expansion of domestic pet market, there is a huge potential demand for pet food, which brings a broad prospect to the pet food market and stimulates the large-scale development of a large number of domestic pet food enterprises.

High quality pet food mainly depends on several aspects

Pet food is mainly composed of grains. As a large agricultural country, China can provide pet food manufacturers with low-cost and rich raw materials, which are powerful factors in pet food processing. A high-quality pet food mainly includes:

1. The contents of protein, fat, energy, minerals, microelements, amino acids and vitamins in pet food should meet the nutritional needs of pets at different stages;

2. The formula of pet food should be scientific and reasonable, according to different growth stages of pet;

3. Pet food can improve the immunity of pet. Summer should be able to prevent heatstroke, and winter should be able to improve the cold resistance of pets. In a word, we should not judge the quality of food simply by whether the pet likes to eat, but comprehensively consider the growth, development and disease resistance of the pet.

From the above three points, it can be concluded that a pet food is not just a simple grain. Adding some ingredients properly will help to improve the quality and nutrition of the product and make it more in line with the advantages of pet food. For example, some animal livers are rich in nutrients, such as: the liver is rich in iron, which is a common food in blood tonic food. The content of vitamin A in animal livers is far higher than that of milk, eggs, meat, fish and other foods, which can enhance the immune capacity of the body. Limited by the technical level, the traditional production method is simple crushing and drying to make meat powder, which is used for feed blending. This kind of meat meal has low protein content, large nutrition loss, poor palatability and low absorption rate. It can not meet the requirements of high quality pet food. However, some animal livers can be hydrolyzed with biological enzyme preparation (special enzyme for pet food attractant), which can become peptone, peptide and amino acid, and also contain organic acid, sugar and inorganic salt, etc., thus retaining the nutrients in the viscera. The reaction is mild and controllable, the product has strong fragrance, good palatability, high attractiveness and high digestibility.

Pet food is the need of pet survival and the foundation of the whole pet industry. In the whole pet industry chain, pet food consumption accounts for more than 75% of the total pet consumption. The domestic pet food industry system is not perfect, and there is a long way to go. We believe that in the future development of pet food, the application of enzyme in pet food occupies a special position.
