Problems solved by technology

[0008] At present, oysters, seaweeds, sea cucumbers, sea urchins, starfish, mussels, hippocampus and other marine animals have been used to develop functional foods such as lowering cholesterol content, preventing cancer, anti-cancer and enhancing immune function, improving gastrointestinal function, and resisting radiation damage. The research level They all only stay on the second-generation functional food, lacking the implementation of international standards, the third-generation functional food whose functional factors are clear and quantified, and the mechanism of action is clear. Although a lot of manpower has been invested in the research of marine biological active substances at home and abroad However, in the development of marine drugs, very few have actually achieved clinical application and industrialization, and even fewer have obtained a new drug certificate. Most of the research and development of marine health products and functional foods focus on anti-cancer and Prevention and treatment of cardiovascular and cerebrovascular aspects.

Embodiment 1

[0028] (1) Weigh 100 grams of Chlorella pyrenoidosa powder into supercritical CO 2 Extraction kettle, close the extraction kettle;

[0029] (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;

[0030] (3) After reaching the set extraction time of 2.5 hours, the extract is collected, and the extracts in the separation kettle 1 and the separation kettle 2 are combined;

[0031] (4) Vacuum concentration (water bath 40°C) extracts to obtain oily extracts or freeze-dried powdered extracts are the antioxidant active ingredients of seaweed.

[0032] The material collected by supercritical carbon dioxide extraction was concentrated in vacuum at low temperature, and the weight of the extract was meas...

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 antioxidant active ingredients, which belongs to marine biotechnology and is used for the research and development of base materials for medical health care products and functional foods. Two technical background [0002] Novel structures and unique functions of marine bioactive substances are 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 study of marine algae bioactive substances, marine medicine has important potential and advantages in realizing this great goal. Utilizing marine bioactive substances to develop unique functional foods, which are difficult to find from terrestrial organisms For example, EPA and DHA in the ocean are rare in terrestrial organisms. Currently, various immune diseases and epidemic diseases such as...
