Embodiment 1

[0011] Take 2Kg of dry granules of Azalea, put it into a solid extraction basket of a supercritical fluid device, place it in an extraction kettle with a volume of 5 liters, heat it, raise the temperature to 50°C, and pass in CO 2 Fluid, the flow rate is controlled at 30L / h. Boost the pressure to 35mpa, control the operating pressure of separation kettle 1# and 2# to be 8mpa and 6mpa respectively, and the temperature to be 45°C and 40°C respectively, after 4 hours of circulation, release 78g of deep red paste material from separation kettle 1#, Detect, the content of astaxanthin is 132g / kg.

Embodiment 2

[0013] Get 200g of Azalea extract (content is 112g / kg) and put it into a 1-liter extraction kettle of a supercritical fluid device, heat it, raise the temperature to 50°C, and feed CO 2 Fluid, the flow rate is controlled to 30L / h, the pressure is raised to 30mpa, the operating pressure of control separation tank 1# and 2# is 8mpa and 6mpa, and the temperature is 45°C and 40°C respectively. After circulating for 4 hours, it is released from the extraction kettle 102g of deep red paste material, after testing, the content of astaxanthin is 193.7g / kg.

Abstract

The present invention discloses a production process for extracting natural astaxanthin by utilizing supercritical fluid CO2. It is characterized by that it utilizes natural plant adonis chrysocyathus, places it in a supercritical fluid extraction equipment and adopts the processes of heating, boosting and injecting CO2 fluid so as to obtain natural astaxanthin.

Description

technical field [0001] The present invention relates to the production technique of plant pigment, is exactly supercritical fluid CO 2 Propose the production process of natural astaxanthin. Background technique [0002] Most of the traditional methods of extracting natural astaxanthin use physical crushing, chemical solvent extraction, distillation and other means, resulting in low product content, high chemical solvent residue, low yield, poor safety, low biological potency and other disadvantages. In addition, except for the production of astaxanthin by chemical synthesis in some western countries, the main biological sources of astaxanthin are aquatic animals, marine microalgae and biological fermentation. However, these sources generally have disadvantages such as low astaxanthin content, high cost, difficult extraction, poor molecular configuration, etc., resulting in natural astaxanthin products that cannot meet the demand. Contents of the invention [0003] The ob...
