Problems solved by technology

Supercritical CO2 extraction is a high-tech, the advantage is that it can simplify the extraction steps, the extraction agent is easy to separate, reduce solvent consumption, no solvent residue, reduce energy consumption, etc., and its product quality is good, but this method is resistant to extraction equipment The pressure requirement is very high, the production cost is high, and the oil yield is 80.1%
[0004] This shows that above-mentioned existing custard oil quality and preparation method all can not satisfy clinical needs, and urgently need to be further improved

Embodiment 1

[0023] Grassland eggs are taken for inspection, egg washing, disinfection, spraying, drying, egg beating, separation of egg white and egg yolk, and then the egg yolk liquid is dried by microwave vacuum drying technology to obtain grassland egg yolk powder.

[0024] This embodiment uses a microwave vacuum drying device to dry the egg yolk, that is, under vacuum conditions, the microwave penetrates the inside of the egg yolk, so that the inside and outside of the egg yolk are heated at the same time, that is, the temperature difference between the inside and outside of the egg yolk is small, and the heating is uniform, and the system is rotated in the microwave vacuum drying device Driven by the drive, the egg yolk makes a rotary motion, so that the egg yolk is heated more evenly and dried more quickly. This drying method makes full use of the characteristics of uniform microwave heating and vacuum drying, solves the problem of difficult heat conduction in vacuum, greatly improve...

Embodiment 2

[0028] Take the prairie egg yolk powder prepared in the above-mentioned Example 1, and use subcritical fluid extraction conditions as follows: extraction pressure 2.5MPa, extraction temperature 70°C, solvent flow rate 2.5kg / h, extraction time 90min. Under these conditions, the obtained prairie egg oil contains 81% triglyceride, 14.3% cholesterol, 1.2% cephalin, and 4.1% lecithin, and the oil yield of the final egg oil is as high as 99.1%.

Embodiment 3

[0030] Take the prairie egg yolk powder prepared in the above-mentioned Example 1, and use subcritical fluid extraction conditions as follows: extraction pressure 3.5MPa, extraction temperature 60°C, solvent flow rate 1.5kg / h, extraction time 150min. Under these conditions, the obtained prairie egg oil contains 82% triglyceride, 14.2% cholesterol, 1.4% cephalin, and 4.2% lecithin, and the oil yield of the final egg oil is as high as 99.3%.

Abstract

The invention discloses yolk oil as well as a preparation method and application thereof. The yolk oil is prepared from greater than or equal to 80% of triglyceride, greater than or equal to 14% of cholesterol, greater than or equal to 1% of cephalin and greater than or equal to 4% of lecithin. The yolk oil is extracted, by supercritical fluid extraction, from the yolk powder prepared from grassland eggs, wherein the yolk powder is dried by a microwave vacuum drying technology; the conditions of the supercritical fluid extraction are as follows: propane serves as a solvent, the extraction pressure is 2.5-3.5 MPa, the extraction temperature is 60-70 DEG C, the solvent flow is 1.5-2.5 kg / h, the extraction time is 90-150 min, and the final oil yield is 99% or more. The grassland yolk oil disclosed by the invention has the advantages of high nutrient content, exact clinical effect, fast effect, quick relief of patient pain, remarkable effect and promotion of popularization. The preparationmethod of the grassland yolk oil disclosed by the invention has the advantages of easiness in operation, low extraction pressure, high efficiency and low cost; moreover, the product does not containresidue of toxic solvents and is very suitable for mass production. The grassland yolk oil disclosed by the invention realizes a remarkable clinical effect on itching, pain, numb, ulcer, edema and thelike.

Description

technical field [0001] The invention relates to the technical field of medicines, in particular to egg butter and its preparation method and application. Background technique [0002] Egg butter, also known as Phoenix liquid, chicken oil, and egg yolk lipid, is the yolk extract obtained by separating and extracting fresh poultry eggs. It is rich in nutrients and has high clinical application value. Egg butter contains nutrients such as triglyceride (TG), cholesterol (CHO), lecithin (Pc), cephalin (PE), protein, a small amount of water and trace riboflavin, and is widely used in clinical medicine and health care Food, cosmetics, pharmaceutical and chemical industries. [0003] At present, the traditional egg oil extraction methods include organic solvent method, dry distillation method, enzymatic method, supercritical CO2 extraction method and so on. Among them, the organic solvent method has small investment in equipment, easy access to the required solvent, and low produc...
