Embodiment 1

[0034](1) Weigh 100 grams of Chlorella pyrenoidosa powder into supercritical CO 2 Extraction tank, close the extraction tank;

[0035] (2) Supercritical carbon dioxide extraction process parameters: pressure 35MPa, temperature 40°C, entrainer dosage 1.5ml ethanol / g material, CO 2 The flow rate is 20L / h, and the pressure and flow rate reach the predetermined value by adjusting the opening degree of the throttle valve and the speed of the carbon dioxide high-pressure pump;

[0036] (3) After reaching the set extraction time of 2.5 hours, the extract is collected, and the extracts in the first separation kettle and the second kettle are combined;

[0037] (4) Vacuum concentration (water bath 40° C.) extract to obtain an oily extract or freeze-dried powdery extract is the seaweed antioxidant active ingredient.

[0038] The material collected by the supercritical carbon dioxide extraction is concentrated in vacuum at low temperature, and the weight of the extract is measured, and...

Abstract

A process for preparing the active antioxidizing component from seaweeds features that the active antioxidizing component is extracted from chlorella by supercritical CO2 at 32-47 deg.C under 35-40 MPa for 1.5-2.5 hr. Its produce can be used for improving immunity, delaying sanility and preventing cardiovascular and cerebrovascular diseases.

Description

a technical field [0001] The invention discloses a preparation method of seaweed anti-oxidation active ingredients, which belongs to the marine biological technology and is used for researching and developing base materials of medicine and health care products and functional foods. Two technical background [0002] Novel structures and unique functions of marine bioactive substances are the active fields of scientific research in the world today for the research and development of new drugs and the development of modern medicine and health care products. [0003] Judging from the many achievements in the research on marine algal bioactive substances, marine medicine has important potential and advantages in realizing this great goal. Use marine bioactive substances to develop unique functional foods, which are difficult to find in terrestrial organisms, such as EPA in the ocean, and DHA is rarely found in terrestrial organisms. At present, various immune diseases and epidem...
