Description

Antioxidant for prolonging shelf life of fresh food for pets as well as preparation method and application of antioxidant
Technical Field
The invention belongs to the field of pet foods, and particularly relates to an antioxidant for prolonging the shelf life of fresh food for pets, a preparation method and application thereof, in particular to an antioxidant with good antioxidant effect for prolonging the shelf life of fresh food for pets, and a preparation method and application thereof.
Background
The dogs and cats of the pet widely enter the life of people in recent years, and with the upgrading of consumption, more and more pet owners have higher requirements on pet ration. Pet ration has also evolved from original single puffed dry grain to a variety of types, with fresh pet grain being increasingly accepted by consumers.
Fresh pet food in the market is relatively short in shelf life in the transportation, storage and sales processes due to the fact that the fresh pet food is relatively high in meat content and water content and no sterilization process, manufacturers can only freeze and refrigerate the fresh pet food, the cold chain cost is high, and spoilage and deterioration occur in the sales processes. The consumers need to heat and return the temperature when using, which also causes bad experience. Also, the food is a cooked pet fresh food, and the food is similar to a process for people to eat meat products, and has a short shelf life for the whole production and sales process though the shelf life can be prolonged to 3-6 months after high-temperature sterilization.
CN112244159a discloses a fresh food for pets and a preparation method thereof, wherein the fresh food for pets is prepared from meat, fruits and vegetables, powder, salt and fennel. The preparation method of the fresh pet food comprises the steps of mixing raw materials of meat, fruits and vegetables, powder, salt and fennel according to the proportion to obtain materials; transferring the material into a forming machine, and extruding particles; transferring the particles into a boiling tank for cooking; and packaging the cooked particles, and refrigerating for preservation. The invention removes the peculiar smell of the raw materials of the product and increases the palatability by controlling the water content in the fresh food of the pet and adding fennel to replace the phagostimulant; the cooking is carried out at a lower temperature, and sterilization and cooking are carried out synchronously, so that the method is energy-saving and efficient, and the damage of high temperature to nutrient substances is reduced. Compared with the traditional puffed dry food, the fresh food for the pets provided by the invention is more abundant in nutrition, better in palatability and more popular with the pets. However, the meat content and the water content are high, and the product is not subjected to anti-putrefaction treatment, so that the storage time of the product is short.
CN111149938A discloses a preparation method of fresh food for pets, firstly cleaning and sterilizing raw materials according to the mass ratio, and weighing according to the ratio of muscle tissue to visceral tissue=8:1:1; uniformly mixing the raw materials, and adding 0.18-1.2% of catfish powder; sealing the product, and curing at 81.0-81.9deg.C for 10-12min under 100-102kPa; back pressure cooling after cooking, and then sending to radiation sterilization for sterilization treatment to obtain the product. The fresh pet food prepared by the method is free from adding any preservative, so that the diet experience of the pet can be ensured, the nutrient components in food materials can be preserved, the loss is avoided, and the fresh pet food has more diet therapy functions, so that the health care product requirement of the pet in daily life can be reduced, and the fresh pet food is instant after being taken out of the bag and has strong competitiveness. But also results in a short shelf life of the product, since no preservative is added.
The use of fresh food for pets is limited by the problem of preservation because of the increasing demands of people for fresh food for pets at present. Therefore, how to provide a method for effectively improving the shelf life of fresh food for pets becomes a problem to be solved urgently.
