Description

Technical Field

[0001] The invention relates to the technical field of pet food, in particular to a functional egg yolk powder for beautifying pet hair and a preparation method thereof. Background Art

[0002] Egg yolks are rich in nutrients such as protein, lecithin, unsaturated fatty acids, calcium, phosphorus, vitamins, etc. The protein, lecithin and unsaturated fatty acids play an important role in maintaining the health of pet's skin and hair growth. While providing comprehensive nutrition and enhancing resistance for pets, egg yolks can promote the healthy growth of pet's hair, help improve the gloss of pet's hair, make pet's hair shiny and prevent the occurrence of skin diseases. However, egg yolks contain a high content of cholesterol, and feeding large amounts of egg yolks is not good for pet's health. Summary of the invention

[0003] 1. Technical issues to be solved

[0004] In view of the deficiencies in the prior art, the present invention provides a functional egg yolk powder for beautifying pet hair, which solves the problem that egg yolk contains a high content of cholesterol and feeding a large amount of egg yolk is not good for the health of pets.

[0005] (II) Technical solution

[0006] The technical solution of the present invention to solve the above technical problems is as follows: a functional egg yolk powder for beautifying pet hair, comprising 80-90 parts by weight of egg yolk liquid, 20-30 parts of isolated soy protein, 10-20 parts of soybean oil, 5-15 parts of soybean lecithin, 5-10 parts of maltodextrin, 3-8 parts of fish oil, 0.01-0.03 parts of antioxidant, and 60-100 parts of processing water.

[0007] The beneficial effects of the present invention are:

[0008] 1) By adding supplements to increase the content of original hair-beautifying nutrients in egg yolk, the effect of egg yolk powder products on the healthy growth of pet hair can be enhanced.

[0009] 2) It dilutes the cholesterol content in egg yolks. While meeting the pet's needs for beautiful fur, it can prevent the pet from ingesting excessive cholesterol when feeding, which is beneficial to protecting the pet's health.

[0010] Based on the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the antioxidants are rosemary extract and sodium D-isoascorbate.

[0012] The beneficial effect of adopting the above further scheme is that the rosemary extract prevents oil oxidation and maintains the flavor of meat, and the sodium D-isoascorbate can preserve and preserve meat.

[0013] Another technical problem to be solved by the present invention is to provide a method for preparing functional egg yolk powder for beautifying pet hair, comprising the following steps:

[0014] Step 1: Dissolve the aqueous phase raw materials: egg yolk liquid, soy protein isolate, maltodextrin, sodium D-isoascorbate and water evenly using a high-speed shear emulsifier.

[0015] Step 2: Dissolve the oil phase raw materials and auxiliary materials: soybean oil, soybean lecithin, fish oil and rosemary extract evenly using a high-speed shear emulsifier.

[0016] Step 3: Mix the water phase and oil phase materials and dissolve them evenly using a high-speed shear emulsifier.

[0017] Step 4: Process the evenly mixed materials with a high-pressure homogenizer.

[0018] Step 5: sterilize the high pressure homogenized material by pasteurization.

[0019] Step 6: The pasteurized material is treated in a spray drying tower to obtain egg yolk powder.

[0020] In the above steps, the high-speed shear emulsifier is used at a speed of 8000-12000rpm; the material high-pressure homogenization treatment pressure is 80-100MPa, and the treatment is 1-2 times; the pasteurization treatment temperature is 60-70℃, and the time is 1-10min; the spray drying inlet temperature is 180-200℃, and the outlet temperature is 75-90℃.
