Problems solved by technology

CN1733009 discloses "A Method for Extracting Fatty Compounds from Bee Pollen", which uses mechanical crushing or grinding to sieve bee pollen and then extracts lipid compounds with supercritical carbon dioxide, avoiding the occurrence of organic solvent residues in the extract , but the process steps are more complicated, and the outer wall of the bee pollen cell composed of sporopollenin is thick and firm, and the pollen cell wall cannot be broken by mechanical crushing or grinding, and the cell wall has a greater blocking effect on the carbon dioxide fluid during the extraction process
Therefore, when mechanically pulverizing bee pollen and then extracting oil with supercritical carbon dioxide, the process requires higher extraction pressure and temperature as well as longer extraction time. This operating condition not only increases the production cost, but also affects the quality of the obtained product.

Abstract

The invention relates to the applied technology field of medicine, foodstuff and health-care food processing and belongs to a method of extracting bee pollen oil from broken bee pollens by supercritical carbon dioxide. The method adopts a continuous process of breaking bee pollens by supercritical carbon dioxide and extracting bee pollen oil subsequently. The process is simple and includes the following steps: firstly, bee pollens are put into the extracting kettle of an extracting device of supercritical carbon dioxide, the temperature and pressure of the extracting kettle are controlled, an exhaust valve is opened and carbon dioxide is rapidly emptied after the pressure is maintained; secondly, carbon dioxide is continuously passed into the extracting kettle, the extraction temperature, pressure, the flow rate of carbon dioxide and the pressure and temperature of the two-stage separation are adjusted, and then bee pollen oil is collected in a separation pot after a certain period of extraction. Compared with the prior extracting method, the method of extracting bee pollen oil from broken bee pollens by supercritical carbon dioxide has the advantages of short extraction duration, high production efficiency, low energy consumption and contamination absence. The obtained product can be directly used as a high-quality material for foodstuff, health-care food and pharmaceutical products, and has a good development prospect.

Description

Technical field: [0001] The invention relates to the technical field of processing and application of medicine and health products, and belongs to a method for extracting bee pollen oil by breaking walls with supercritical carbon dioxide. Background technique [0002] Bee pollen is formed by mixing the sperm cells of plants collected by bees, plus their own glandular secretions, saliva and honey. Experimental studies and clinical applications have shown that bee pollen can effectively prevent and treat cardiovascular and cerebrovascular diseases and prostate diseases, and has anti-oxidation, anti-aging, immune-enhancing, and cosmetic effects. As a natural nutrient bank, bee pollen is rich in a variety of amino acids, proteins, enzymes, vitamins, unsaturated fatty acids, phospholipids, flavonoids and other functional components, among which unsaturated fatty acids, phospholipids and other fat-soluble components have high utilization value and development prospects.
