Embodiment 1

[0028] Embodiment 1 A kind of vitamin D linseed oil nanoemulsion

[0029] The present embodiment provides a nanoemulsion containing vitamin D linseed oil, its formula is (by mass percentage): vitamin D 0.4%, linseed oil 5%, soybean lecithin 1%, ascorbyl palmitate 0.02%, Ethyl p-hydroxybenzoate 0.02%, the balance is water.

Embodiment 2

[0030] Embodiment 2 A kind of preparation method of vitamin D linseed oil nanoemulsion

[0031] This embodiment provides the preparation method of the nanoemulsion containing vitamin D linseed oil described in the above-mentioned embodiment 1, comprising the following steps:

[0032] 1) Prepare the water phase: take the prescribed amount of purified water, adjust the pH of the purified water to 8-12 with 2% sodium hydroxide solution, add the emulsifier into the water, and shear at 50-60°C until uniformly dispersed under nitrogen protection ;

[0033] 2) Prepare the oil phase: add vitamin D, antioxidants, and preservatives to the linseed oil, heat and stir, control at 40-50°C, and mix well;

[0034] 3) Add the oil phase to the water phase, shear to make colostrum, and adjust the pH value of the system to 6.7;

[0035] 4) The colostrum is subjected to high-pressure homogenization using a gradient boost method to prepare a nanoemulsion;

[0036] The gradient step-up is specifi...

Embodiment 3

[0037] Embodiment 3 A kind of preparation method of vitamin D linseed oil nanoemulsion

[0038] In this example, the method described in Example 2 was used to prepare the vitamin D-containing linseed oil nanoemulsion in Example 1, the only difference being that the pH value of the system in step 3) was 6.0.

Abstract

The invention relates to a nano-emulsion prepared from vitamin D and linseed oil as well as a preparation method and application of the nano-emulsion. The nano-emulsion is prepared from the following raw materials by mass percent: 0.02-1% of the vitamin D, 1-10% of the linseed oil, 0.5-3% of an emulsifying agent, 0.005-0.5% of an antioxidant, 0.005-0.5% of a preservative and the balance of water. The vitamin D and the linseed oil are prepared into nanoparticles by the food grade emulsifying agent, a proper dosage of the emulsifying agent and an appropriate PH value are determined, and granulation is realized by a two-step method, so that the problems that the vitamin D and the linseed oil are easily oxidized, and emulsion particles are poor in stability can be effectively solved.

Description

technical field [0001] The invention relates to a vitamin D-containing linseed oil nanoemulsion, a preparation method and application thereof, and belongs to the technical field of food health products. Background technique [0002] Flaxseed oil, also known as linseed oil or linseed oil, is a drying oil obtained from flaxseed. Flaxseed oil contains special nutrients, especially α-linolenic acid as high as 50%, which has important physiological functions and high nutritional value. [0003] Vitamin D is a sterol derivative with anti-rickets effect, also known as anti-rickets vitamin. At present, it is considered that vitamin D is also a steroid hormone, and the most important members of the vitamin D family are VD2 (ergocalciferol) and VD3 (cholecalciferol). [0004] In the prior art, vitamin D3, as a fat-soluble vitamin, has low solubility, and processing and storage conditions such as light, temperature, and oxygen will lead to its isomerization or oxidation, which is unf...
