In order to meet the different requirements of various dogs, the food for dogs has great progress in component nutrition and preparation process research. At present, the preparation process of the canine pet food is unified, and the canine pet food is mostly obtained by smashing and uniformly mixing all the nutritional ingredients, then modulating, puffing, granulating and curing, wherein research hotspots are mainly on the component preparation of canine foods.

In the patent publication numbers CN116686917A and CN116406749, plants and insect yellow meal worms are used as main sources of proteins and are compounded with the rest materials, so that the use of animal proteins such as livestock meat, poultry meat and the like is reduced, and the problem of 'people and livestock contending for food' is relieved. In the patent of publication No. CN115997859A, through adding yeast selenium with antioxidant effect, beer yeast extract and anti-inflammatory effect of perna canaliculus, prebiotic fructo-oligosaccharide and mannooligosaccharide, the immunity of working dogs is enhanced, joints are protected, and the rapid recovery of the working dogs after exercise is facilitated. In the patent of publication No. CN115462467A, through adopting the enzymolysis chicken liquid of which the protein is decomposed into small molecular peptide, the better absorption of amino acid is promoted, and the combination of hericium erinaceus, cabbage and the like provides rich amino acid, so that the health of canine hair is ensured, and the hair stretching force is improved. The patent of publication No. CN115024422A is beneficial to the health care and growth of pet dogs by adding dendrobium candidum freeze-dried powder to provide rich nutrients. The patent of publication No. CN114886034A adds a bacteriostatic complex into the dog food, promotes microecology balance of the dog intestinal canal, promotes beneficial bacteria propagation, and solves the problems of dysbacteriosis and intestinal canal diseases caused by unbalanced proportion of the material object when the pet dog eat the food for a long time. The patent of publication No. CN114788551A uses cowpea, white hyacinth bean and other low-sugar substances to replace the traditional high-sugar and high-calorie raw materials, combines with alfalfa extract and other substances to regulate blood fat, celery and other dietary fibers to promote digestion, and astragalus and other traditional Chinese medicinal materials to promote blood circulation, supplement qi and improve immunity, so as to solve the problem of high blood sugar and blood fat caused by traditional dog food. In addition, the utilization rate of the phytate phosphorus in the canine food is improved by adding enzyme preparation phytase, chinese herbal medicines or natural extracts are added to benefit spleen and stomach, and intestinal digestion is promoted by adding probiotics such as bacillus subtilis, so that the immunity of the canine body is improved.

In summary, the research on the conventional dog food is focused on screening and collocating the dog food components, and various raw materials or substances such as special nutrient substances, enzyme preparations, probiotics, prebiotics and the like are adopted to supplement enough nutrition for dogs, reduce the intake of bad substances, enhance the immunity of dogs to resist diseases and improve the health level of dogs. However, the dog food is usually too dependent on the unique effects of the components, and most of the components are either expensive or prepared by special methods, so that the dog food is high in cost and high in market price, and cannot be popularized on a practical scale. Meanwhile, the research and development of the conventional canine food is excessively focused on the regulation and control of the nutritional ingredients in the ingredients, the performances of hardness, chewing taste and the like of the canine food are not considered, and the regulation effect of canine organisms on intestinal tracts is not considered. In the long term, the method of simply relying on the nutritional ingredients in the dog food cannot fundamentally improve the health level of dogs.

Konjac glucomannan is white powdery water-soluble natural polysaccharide, has strong hydrophilicity, and numerous oxygen-containing groups such as hydroxyl groups and water molecules gather through acting forces such as molecular dipoles, hydrogen bonds, instant dipoles, induced dipoles and the like, so that huge macromolecules are formed. Therefore, the konjak glucomannan has extremely high water absorption and swelling performance, is favorable for absorbing internal moisture and prolongs the storage time. Meanwhile, konjak is taken as one of nutrient dietary fibers, is beneficial to improving the intestinal health effect, and can be applied to the field of foods including dog foods.

Further, by adopting a steam heating circulation mode, flavor substances in the bone soup base are circularly steamed out and finally adsorbed in the outer pores of the konjak glucomannan skeleton, so that the taste of the phagostimulant is lightened, the adverse effect of the taste of the phagostimulant on inadaptable people is reduced, the selection purchasing desire of dog food is improved, namely the commodity value of the dog food is improved, and meanwhile, the stability of nutritional components in the skeleton is also reduced by only the phagostimulant on the outer layer.

Furthermore, the nutritional ingredients are prepared into the aqueous nutritional paste and then extruded into the konjak glucomannan skeleton, and as the konjak glucomannan skeleton has water absorption, filling power is generated between the nutritional paste and the konjak glucomannan skeleton due to water content difference, so that the nutritional paste is promoted to smoothly enter the pores of the skeleton and fully fill, and the addition amount of the nutritional ingredients in the konjak canine food is ensured.

Further, a drying plastic process of heating at a high temperature and then cooling and heating air blasting is adopted, the konjak glucomannan skeleton is heated and expanded to enable the nutritional paste to be further and uniformly dispersed in the skeleton, and then the moisture is removed through the heating air blasting to rapidly dehydrate, so that the moisture content in the konjak glucomannan skeleton is reduced, the hardness, flexibility and chewing feel characteristics of the konjak glucomannan skeleton are maintained, meanwhile, the drying of konjak dog food is ensured, and the preservation time of the konjak dog food is prolonged.

Further, by controlling the temperature of drying plasticity after extruding into the nutritional paste, the denaturation and inactivation of beta-mannase in the nutritional paste are avoided, the beta-mannase acts on konjak glucomannan and degrades the konjak glucomannan into konjak oligosaccharide, the konjak oligosaccharide can be combined with lectin on the surface of pathogenic bacteria in animal intestinal tracts, so that the capability of adhering and invading intestinal mucosa is lost, the proliferation of beneficial bacteria such as bifidobacteria in the intestinal tracts is promoted, the intestinal tract immunity function is enhanced, the invasion and adhesion of intestinal pathogenic bacteria to the intestinal mucosa are prevented, the growth of harmful bacteria such as intestinal putrefying bacteria is inhibited, the generation of toxic and harmful substances is reduced, the intestinal peristalsis is promoted, the excretion of the toxic and harmful substances is accelerated, and the digestibility of fat and protein is improved, so that the gastrointestinal tract health of dogs is further improved.

Furthermore, the blending of the konjak glucomannan in the konjak canine food and various substances in the internal nutritional components of the konjak glucomannan further strengthens the performance of the konjak canine food, the zein can form a bacteriostatic film at the pore of the konjak glucomannan skeleton while realizing the nutritional value, thereby being beneficial to prolonging the shelf life of the konjak canine food, and the glutenin can assist the konjak glucomannan skeleton to improve the hardness, flexibility and chewing sense of the konjak canine food while realizing the nutritional value, and avoiding the chewing sense and loss of the nutritional value of the konjak canine food.
