Novel preparation technology of egg yolk oil

Abstract

The invention relates to a preparation method of egg yolk oil, which comprises the following steps: 1) granulating: using egg yolk powder which is qualified in quality acceptance to prepare cylindrical particles with the particle size of [phi]3mm*5-6mm; 2) charging: filling a charging barrel with the granulated cylindrical egg yolk powder particles, and putting the cylindrical egg yolk powder particles into an extraction kettle; 3) extraction: increasing the pressure and starting extraction after a stable state is reached, wherein the main parameters of extraction are as follows: the extraction pressure is 20-27 Mpa, the temperature is 32-50 DEG C, the flow rate is 2-5t / h, and the extraction time is 4.5-6h; 4) separation: enabling the extracted mixed material to pass through a separation kettle, wherein the egg yolk oil is settled, separated and separated out at the bottom of the separation kettle, the separation pressure is 5-8 MPa, and the temperature is 20-40 DEG C; 5) egg oil discharging: discharging the separated egg oil from an oil outlet at the bottom of the separation kettle every 30-60 minutes; and (6) barreling, sealing and storing: barreling the egg yolk oil, conducting sealing and packaging, and conducting refrigerating and storing in a cool storage at 0-20 DEG C.

Description

technical field [0001] The invention relates to a new preparation process of egg oil, in particular to a new technology for preparing egg oil by supercritical carbon dioxide fluid extraction. Used in food and medicine. Background technique [0002] Egg butter is oil extracted from egg yolk, also known as chicken fish, phoenix oil, etc. It is a good medicine for treating mild burns, because egg oil is rich in vitamins A, D and lecithin, etc. It plays an important role in regeneration and metabolism, and it is very effective in treating burns. [0003] At present, there are many methods for preparing egg yolk, but most of them are organic solvent extraction methods. A large amount of organic solvents need to be added during the extraction process, and measures need to be taken to control the residue of organic reagents, resulting in increased costs, more time-consuming, and low product safety. , and most organic solvent extraction methods have cumbersome operation steps and ...

Problems solved by technology

[0003] At present, there are many methods for preparing egg yolk, but most of them are organic solvent extraction methods. A large amount of organic solvents need to be added during the extraction process, and measures need to be taken to control the residue of organic reagents, resulting in increased costs, more time-consuming, and low product safety. , and most organic solvent extraction methods have cumbersome operation steps and low extraction efficiency

At present, there is also the technology of using supercritical CO2 fluid extraction to extract egg oil, but the application is not very wide, and the extraction process parameters adopted are high extraction pressure, high extraction temperature, high energy consumption, and low extraction efficiency.
