Embodiment Construction

[0006] Below in conjunction with embodiment the present invention will be further described

[0007] To extract astaxanthin from Calendula officinalis, firstly treat the raw material on Calendula officinalis with water or a water-like solvent to remove glycosides soluble in water, then mix the processed raw materials with ethanol / ethane, and the mixing ratio is 50 : 50(L / L), stir in a dark and cool environment to make it evenly mixed, or grind it in ethanol with a stirrer, then add ethane to ensure safety, and store in a dark and low-temperature environment. Finally, filter through a filter on a vibrating sieve. If the filter screen is blocked, wash with ethanol: ethane (50: 50), and use the filtered and cleaned liquid as the basic purified product. Such purified products include water-soluble, ethanol-soluble and ethane-soluble substances, including pigments and glycosides. Then add 1 part of water to 2.5 parts of basic purification, transfer to the separator to remove the b...

Description

technical field [0001] The invention relates to the technical field of obtaining astaxanthin from natural plants, specifically a method for extracting astaxanthin from Calendula officinalis. Background technique [0002] Astaxanthin is a food additive. Can be applied to human food and animal feed additives. Astaxanthin is contained in many animals and plants, but due to the limitation of resources and its content, the current acquisition of astaxanthin is not economical. Synthetic astaxanthin can also be used in food and feed, but the cost of obtaining it is high, which increases the production cost. More importantly, the use of synthetic astaxanthin does not meet the reality of modern people's pursuit of "naturalness". Therefore, astaxanthin currently used in human food and animal feed has restricted the development of related industries due to its disadvantages such as few resources, complicated methods or processes, and high prices. Contents of the invention [0003]...
