Problems solved by technology

Phospholipids widely exist in soybeans and egg yolks. my country is one of the main soybean producing countries in the world. Soybean oil foot resources are very rich, but its comprehensive utilization is not ideal. Soybean oil foot is used to produce powdered phospholipids, and then to produce medicinal and injection lecithin It has broad development space and good prospects, but most of the existing technologies are organic solvent extraction, the technology is backward, the production environment is not good, it is flammable and explosive, the product extraction rate is low, and the quality grade is not high

Embodiment Construction

[0022] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0023] The method for preparing powdered phospholipids from soybean oil residues: 1. material selection, select soybean oil residues that are freshly cold-pressed for no more than three months; 2. concentrate, put soybean oil residues into a sealed container, vacuumize, and heat to 80 ℃-90℃, keep for two hours to get concentrated phospholipids; 3. Extraction, put the concentrated phospholipids in the extraction tank, add 2L liquid CO2 to 1kg concentrated phospholipids 2 The proportion of input liquid CO 2 , the extraction pressure is 25MPa, the temperature is 40°C-50°C, and the time is 100-150m; 4. Filtration and granulation, discharge the extracted material into a closed filter tank, and filter with multi-layer sieve cloth with a pore size not greater than 12μm , through a granulator to make granular powder with a particle size of 18-30cmm. Dry under reduced pr...

Description

technical field [0001] The invention relates to the technical field of extracting lecithin from soybeans, in particular to a method for preparing powdered phospholipid, medicinal and injection lecithin from soybean oil foot. Background technique [0002] With the development and progress of science and technology, the research and development of phospholipids continue to deepen. People are increasingly aware of the importance of phospholipid products to humans. Recent research results show that phospholipids are not only a multifunctional natural health product, but also exhibit excellent performance in various fields such as feed, beauty and cosmetics, medicine, and industrial and agricultural production. As a kind of liposome, it is one of the main components of the cell membrane and the material basis of cell multifunctionality. It plays an important role in the regulation of body functions, and its medicinal value and functional role are gradually highlighted. Phosphol...
