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.

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...
