Problems solved by technology

[0006] CN1974582A discloses a method of using ultrasonic enhancement to extract lecithin with 80%-95% ethanol as an extractant. According to the content of the literature, this method is indeed a method for improving extraction efficiency. It is also in industrial production. In terms of using flammable and explosive organic solvents as extraction agents, the manufacture of ultrasonic equipment also has problems of relatively large investment and power consumption.
[0007] CN10102905A discloses a lecithin crude product extracted from egg yolk liquid by eating ethanol first, and then the crude product is extracted with supercritical CO 2 The method of extracting and obtaining ≥70% lecithin after removing neutral fat, although this method is beneficial to protect the biological activity of egg yolk lecithin, but the source of raw materials for large-scale production equipment needs to rely on egg comprehensive processing enterprises, in addition, supercritical CO 2 The extraction equipment investment is also relatively large

Abstract

The invention discloses a production process for oil-free powdery yolk lecithin. The production process comprises the following steps: in a combined stirring tank, removing neutral fat in yolk powder with acetone and extracting yolk lecithin in the yolk powder with absolute ethanol to obtain the oil-free powdery yolk lecithin. The invention also discloses a structure of the combined stirring tank. The prepared oil-free powdery yolk lecithin has an acetone insoluble substance content more than or equal to 95 percent and a lecithin content more than or equal to 75 percent. The production process is characterized by high extraction efficiency, convenient operation, low cost and suitability for industrialized production. The combined stirring tank of the invention is used by combining a blade type stirrer and a disk turbine type stirrer to solve the problem that single stirrer cannot make fluid rapidly achieve a turbulent flow condition; the blade type stirrer can stir the upper fluid up and down to rapidly achieve a turbulent flow condition; and the disk turbine type stirrer can generate strong shearing force to fluid so as to achieve excellent material dispersion effect.

Description

technical field [0001] The invention belongs to the technical field of biochemical engineering, and in particular relates to a production process of oil-free powdery egg yolk lecithin. Background technique [0002] Phospholipids are the main components of animal cell membrane systems, so they are one of the most important basic substances for the formation of life. The proportion in the nervous and visceral systems is higher than in other systems, such as: phospholipids in the brain, liver, egg yolk, plant seeds, etc. The proportion is extremely high. As phospholipids are biologically active substances with unique physical and chemical properties and nutritional value, phospholipids are more and more widely used in food, health products, medicine and feed industries around the world. Human consumption of phospholipids can reduce high blood lipids, improve the symptoms of fatty liver, brain and intelligence, and delay aging and other physiological functions. [0003] Phosph...
