Problems solved by technology

Adding three-grain fish oil directly to cat food will seriously affect the indoor air due to a strong fishy smell, and the three-grain fish oil is easily oxidized and deteriorated when exposed to the air, or the mildew smell is extremely unpleasant. Add three-grain fish oil in summer The safe storage period of fish oil cat food is only 1-2 months, and the calculation from the product production, commercial retail and distribution links takes 20-30 days at the fastest, so the actual storage period is very short

Abstract

The invention discloses a salmon oil microcapsule cat food additive and a preparation method thereof. The salmon oil microcapsule cat food additive is prepared from an oil core and a capsule shell, wherein the oil core is prepared by the following steps: taking salmon belonging to marine fishes as a raw material, carrying out cryogenic grinding and CO2 supercritical extraction to obtain fish oil taking fatty acid as a main ingredient, and then adding vegetable oil and a surfactant, wherein the vegetable oil is one or more of corn germ oil, peanut oil, rice bran oil, cinnamon oil and clove oil; the capsule shell is a natural high polymer material aqueous solution and is prepared from one or more of gelatin, cured corn starch, cured potato starch, chitin and alginate; the surfactant is one or more of polyoxyethylene (20) sorbitan monooleate, polyoxyethylene monoleate and polyoxyethylene (4) sorbitan monolaurate. The natural high polymer material is used to clad the salmon oil, and the problems of strong fishy smell of the salmon oil, the pollution to indoor air, high possibility of oxidation and short storage life are solved.

Description

technical field [0001] The invention relates to the technical field of pet cat feed additives, in particular to a salmon oil microcapsule cat food additive and a preparation method thereof. Background technique [0002] Several nutrients in pet cats cannot be synthesized by themselves, and can only be obtained by eating foods such as mice and fish. After the wild cats are domesticated, they become pet cats, unable to prey on mice and fish from the wild. Due to malnutrition, the pet cats have gray coats and are prone to illness and death. Salmon oil is a fatty acid extracted from deep-sea salmon. It is rich in nutrients needed by pet cats and is one of the excellent additives for cat food. Adding three-grain fish oil directly to cat food will seriously affect the indoor air due to a strong fishy smell, and the three-grain fish oil is easily oxidized and deteriorated when exposed to the air, or the mildew smell is extremely unpleasant. Add three-grain fish oil in summer The ...
