Problems solved by technology

It can be applied to human food and animal feed additives Many animals and plants contain astaxanthin, but due to the limitation of resources and their content, it is currently uneconomical to obtain astaxanthin
Synthetic astaxanthin can also be used in food and feed, but the cost of obtaining it is expensive, which increases the production cost. More importantly, the use of synthetic astaxanthin does not conform to the reality of modern people's pursuit of "naturalness"
Therefore, astaxanthin currently used in human food and animal feed restricts the development of related industries due to the disadvantages of less resources, complicated methods or processes, and high prices.

Embodiment Construction

[0007] The present invention will be further described below in conjunction with embodiment.

[0008] To extract astaxanthin from Marigold officinalis, first treat the raw material on Marigold officinalis with water or a water-like solvent to remove water-soluble glycosides, then mix the processed raw materials with ethanol hexane, and the mixing ratio is 50: 50(V / V), stir in a dark and cool environment to make it evenly mixed, or grind it with a mixer in ethanol, then add hexane 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 it with ethanol: hexane (50:50), and use the filtered and washed liquid as the basic purified product. Such purified substances include water-soluble, ethanol-soluble, and hexane-soluble substances, including pigments and glycosides. Then add 1 part of water to 2.5 parts of basic purification, transfer to a separator to remove the bottom e...

Description

1. 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. 2. Background technology [0002] Astaxanthin is a food additive. It can be applied to human food and animal feed additives Many animals and plants contain astaxanthin, but due to the limitation of resources and content, it is currently uneconomical to obtain astaxanthin. 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 restricts the development of related industries due to its shortcomings such as few resources, complicated methods or processes, and high prices. 3. Contents of the invention [0003] The inventor...
