Description

Preparation method, formula and application of functional pet snack Technical Field The invention relates to the technical field of functional pet snacks, in particular to a functional pet snacks prepared by taking lotus root starch and xanthan gum as raw materials, adding whole egg powder and shark chondroitin to prepare hydrogel raw materials and adopting a 3D printing technology so as to realize the functional designs of relieving arthritis, reducing blood fat, resisting oxidation and the like. Background In recent years, with the rapid development of global economy and the continuous updating of people's consumption concept, our pet economy is rapidly rising, and people pay attention to their own diet, nutrition and health, and meanwhile, attention to the nutrition and health of pets is also beginning to be increased. With the upgrading of domestic pet demands, pet breeders have increasingly perceived scientific feeding concepts, and pet foods have not been limited to simple satiety effects. More research is currently focused on different nutritional requirements of different varieties, ages and functional pets, and the development of diversified functional pet foods has become a main development direction of pet foods. The functional pet snack is different from the traditional pet food, and is a pet snack with special health care function and added with special functional auxiliary materials. It is developed for specific pets that need to supplement certain nutrients or improve physical functions, and functions to enhance physical health to some extent, although it cannot directly act as a drug. Functional pet treats are mainly comprised of tooth cleaning snacks (which can help clean the teeth of a pet, reduce plaque and calculus formation, and thus maintain oral health), gastrointestinal health snacks (which contain probiotics and fibers, which can help improve the digestive system health of a pet), skin and hair health snacks (which are rich in Omega-3 and Omega-6 fatty acids, which can help improve the skin and hair health of a pet), joint snacks (which contain antioxidants, tocopherols, sulfides, and the like, which help reduce inflammation occurrences). Although pet treats are more types, the product is more single in form, most are meat products, and the easy intake of excess fat is detrimental to the health of elderly and obese pets. The joint pet treat products are most in the form of tablets, ointments, granules, which have many drawbacks. The tablet product is prepared by simply mixing, granulating and tabletting the functional components, has no due effect on the dispersion and dissolution of the medicinal components, has higher hardness, is difficult to chew for old dogs and cats, and has poor palatability. The paste product has high moisture content, is easy to generate harmful microorganism propagation, has the defects of unstable active ingredients, difficult preservation, easy putrefaction and flatulence, and has the problems of color change and the like in the storage process. The granule is required to be soaked in water for use, dogs and cats, especially cats, do not like drinking water, and resist drinking water administration at the same time, so that the drug effect is reduced over time, and a specific effect is difficult to play. In order to solve the existing defects of the functional pet snack, the invention uses the 3D printing technology to customize food according to the specific requirements of the pet, can manufacture pet snacks with various shapes and textures, not only can increase the appetite and interests of the pet, but also has specific functionality. 3D printing, also known as additive manufacturing (FDM), is an emerging technology for layering, stacking and piling raw materials based on a Computer (CAD) mathematical model. The 3D printing technology can reduce the use of materials, improve the yield of products, and manufacture entities with unique internal structures which are difficult to process by the traditional technology, and is recognized by economics as a technology capable of promoting the development of the third industrial revolution. Therefore, 3D printing technology is widely used in the fields of aerospace, mechanical manufacturing, automotive, biomedical, food, artwork, and the like. Compared with the traditional food modeling means, the food 3D printing technology has the advantages of high energy utilization efficiency, environmental protection, personalized customization support, complete nutrition collocation and the like, and by utilizing the 3D printing technology, food can be accurately designed and manufactured through the adjustment and control of printing materials and the content of nutritional ingredients, so that the nutritional requirements of individuals based on health states and physical activities can be met, and common food printing ink comprises chocolate, candies, starch, pomace and the like. Starch has received extensive atten
