Embodiment 1

[0030] Embodiment 1: the present invention is a kind of nano-vitamin D3 that is used for feed production, and the nutrient content in every 1 kilogram of nano-vitamin D3 powders is: Vitamin D3 500,000 international units (IU) / gram (g), surplus is carrier . Its preparation method comprises the following steps:

[0031] 1) Weigh 100g of vitamin D3 raw material, and mix it according to the mass ratio of vitamin D3 raw material:VD3 oil at 1:1 under the preheating condition of 45°C;

[0032] 2) Keep preheating at 45°C, and perform ultrasonic emulsification on the mixture of vitamin D3 raw materials and VD3 oil for 8-12 minutes, so that the average particle size of the obtained nanoemulsion emulsion is 3-5um;

[0033] 3) placing the nanoemulsion obtained above in a sterile dry environment for 1 to 2 days, so that the average particle size of the obtained nanoemulsion is 0.3 to 2 μm;

[0034] 4) Add 120ml of absolute ethanol to the cleaned nanoemulsion emulsion and stir until clear...

Embodiment 2

[0049] Contrast test of nano-vitamin D3, ordinary vitamin D3 and water-soluble vitamin D3 in water.

[0050] The test results are shown in the table below:

[0051]

[0052]

[0053] It can be seen from the above table that the nano-vitamin D3 has the best water solubility, so it can completely meet the needs of the body in the water-soluble medium in the body of livestock and poultry.

Embodiment 3

[0055] In the nanoemulsion emulsification process, under different ultrasonic emulsification conditions, the average particle size of the emulsified emulsion has a direct relationship, such as figure 1 As shown, the emulsified particle size obtained in about 10 minutes is the best. figure 1 It is the average particle size change diagram of the ultrasonic emulsification time to the nanoemulsion emulsion.

Abstract

The invention relates to a preparation method of nano vitamin for feed, particularly relates to a preparation method of nano vitamin D for a coating of feed, aims at overcoming the problem of reduction of biological activity due to the heating of the vitamin D3 heated during preparation of fat-soluble vitamin into nano vitamin D3, and synchronously provides a novel preparation method of the nano vitamin D3. The vitamin D3 is a steroid derivate and has the effect of resisting rickets, so that the vitamin D is called anti-rickets vitamin. According to the preparation method, the size of the particles of the vitamin D3 is controlled to be less than 50nm by the ultrasonic technology under the normal temperature and normal pressure so as to generate new form of nano vitamin D3 for the feed; compared with the common vitamin D3 in physical properties, the nano vitamin D3 for the feed has the advantage that the solubleness, absorbing rate, nutrition, and the advantages in physiologic and biochemical process in the body are obviously improved.

Description

technical field [0001] The invention belongs to the technical field of vitamin industry, and relates to a preparation method of nano-vitamin for feeding, in particular to a preparation method of nano-vitamin D3 for feeding. technical background [0002] Vitamin D is a steroid derivative that has anti-rickets effect, so it is called anti-rickets vitamin. There are many types of vitamin D, among which the more important ones are vitamin D2 (ergocalciferol) and vitamin D3 (cholesterol). The structure of the two is very similar, and they are easily soluble in organic solvents such as fat, oil and ether, but insoluble in water, so they are called For fat-soluble vitamins. Vitamin D3 is often used in feed production to supplement vitamin D for feeding. Vitamin D is sensitive to air and light, especially when heated, so it should be stored in a dark environment. [0003] Vitamin D3 has a wide range of biological functions: regulating calcium and phosphorus metabolism, improving ...
