Description

Large-particle food wrapped with instant freeze-dried particles and having oral health-care function for dogs and cats and preparation method of food Technical Field The application relates to large-particle food with oral health care functions of dogs and cats and coated with instant freeze-dried particles and a preparation method thereof, and belongs to the technical field of pet foods. Background The oral health problems of dogs and cats are common, and the main cause is that dental plaque (a biological film containing bacteria) is accumulated on the surface of teeth, so that dental calculus is mineralized and formed, and gingivitis, halitosis and even tooth fall are caused. The method is based on the fact that commercial dog and cat food particles produced by industrial design are generally small and crisp, and dogs and cats are not good at chewing, so that the dogs and cats directly swallow the food, biting actions are few, and saliva secretion is insufficient. The reduction of salivary secretion results in the reduction of self-cleaning ability of the oral cavity, the reduction of pH adjustment ability, the reduction of antibacterial and bacteriostatic actions (the saliva contains lysozyme, lactoperoxidase and the like), and the natural defense function of the saliva cannot be fully exerted. In the prior art, in order to solve the problem, 1) mechanical cleaning grain is generally adopted, teeth are rubbed by fibers or special structures to remove dental plaque during biting, as described in patent application US5431927A, a pet food with an expansion stripe structure is broken to provide mechanical cleaning effect during biting, however, the cleaning effect of the product is limited to molar teeth or tooth tips and lacks a comprehensive action mechanism on oral cavity, 2) grains of oral care agents are added, antibacterial ingredients, anti-tartar ingredients and the like are directly mixed into feed, as in patent application US2017/0339978A1, the tooth cleaning effect is improved by covalent combination of hydrolyzed protein and high-branched starch, most active ingredients are easy to denature during high-temperature puffing, and an internal mixing mode is difficult to ensure effective release of the ingredients in oral cavity and cannot form effective concentration in the oral cavity locally, and 3) local release type products, such as spray, gel and the like, are required to be operated by hands, the compliance of dogs and cats is poor, and the oral cavity problem is closely related to microecological unbalance of intestinal tract, and the product is limited to local treatment and the system is limited to the regulation of oral cavity problem. Aiming at the problems that the grains of the pet are small, the biting time is short, the saliva secretion is insufficient, the active ingredients are easy to inactivate in the processing process and are difficult to effectively release in the oral cavity in the prior art, the market needs a grain scheme which can not only provide effective mechanical cleaning, but also fully stimulate the saliva secretion and accurately release the active ingredients in the oral cavity. Disclosure of Invention In order to solve the problems, the large-particle food with the oral health care function for dogs and cats, which is coated with the instant freeze-dried particles, is provided, saliva secretion can be effectively stimulated by matching with biting through a large-particle design, and instant freeze-dried active ingredients are attached to the surfaces of the large-particle by adopting a coating technology, so that dental plaque and dental calculus formation can be effectively inhibited, halitosis can be eliminated, hemostasis can be converged, gingivitis can be relieved, and in addition, the overall health of dogs and cats can be obviously improved through oral cavity-intestinal microecological cooperative regulation. The application provides a large-particle food with oral health care function for dogs and cats, which is coated with instant freeze-dried particles, and comprises the following components: a) The grain base material particles are used as grains for dogs, the size of the grains is more than or equal to 20mm, the hardness of the grains is 15-25 kgf/cm 2, and the size of the grains for cats is more than or equal to 12mm, the hardness of the grains for cats is 12-20 kgf/cm 2; b) The external spraying system comprises, by weight, 0.1-0.15 part of lecithin, 0.002-0.003 part of monoglyceride, 0.001-0.003 part of vitamin E and 0.8-1.2 parts of chicken oil; c) The instant freeze-dried particle layer comprises, by weight, 0.1-0.2 part of fucoidan, 0.02-0.05 part of lysozyme, 0.04-0.08 part of tea polyphenol, 0.02-0.04 part of zinc gluconate, 0.05-0.1 part of acacia, 0.03-0.1 part of glutamine, 0.01-0.02 part of vitamin B, 0.01-0.04 part of vitamin B and 0.02-0.07 part of glycine. Optionally, the total weight of the instant freeze-dried particle layer is 0.3-0
