Embodiment 1

[0038] The method for comprehensively extracting polyunsaturated fatty acids and polysaccharides from seaweeds of the present invention comprises the following steps:

[0039] Polyunsaturated fatty acid extraction:

[0040] A. Soak Sargasso algae in tap water equivalent to 20 times its weight for 5 minutes, then wash once with tap water and deionized water, and then bake at 80°C for 10 hours; after drying, crush it into 10-mesh Sargassum powder, Disperse Sargassum powder in petroleum ether according to the ratio of material to liquid at 1:5, and perform ultrasonic crushing. The ultrasonic power is 60W, the crushing time is 5min, and the temperature is maintained at 80°C during crushing;

[0041] B. The suspension after ultrasonic crushing is subjected to solid-liquid separation, and petroleum ether is added to the separated liquid as an extraction solvent, so that the solid-liquid ratio of seaweed powder and extraction solvent is 1:5, and the extraction solvent and solid resid...

Embodiment 2

[0050] The method for comprehensively extracting polyunsaturated fatty acids and polysaccharides from seaweeds of the present invention comprises the following steps:

[0051] Polyunsaturated fatty acid extraction:

[0052] A. Soak Sargassum in tap water equivalent to 30 times its weight for 10 minutes, then wash twice with tap water and deionized water, and then bake at 78°C for 12 hours; after drying, crush it into 20-mesh Sargassum powder, Disperse Sargassum powder in petroleum ether according to the ratio of material to liquid of 1:8, and perform ultrasonic crushing. The ultrasonic power is 65W, the crushing time is 10min, and the temperature is kept at 79°C during crushing;

Abstract

The invention discloses a method for comprehensively extracting polyunsaturated fatty acid and polysaccharide from seaweed, which comprises the following steps: by using seaweed as a raw material, extracting polyunsaturated fatty acid, separating the seaweed from which the polyunsaturated fatty acid is extracted, and extracting the polysaccharide by using the seaweed from which the polyunsaturatedfatty acid is extracted. The method can improve the extraction rate, reduce the usage amount of seaweed and an extraction solvent and the generation of wastes, improve the resource utilization efficiency, reduce the cost and improve the economic value of seaweed.

Description

technical field [0001] The invention relates to the technical field of marine biological processing, in particular to a method for comprehensively extracting polyunsaturated fatty acids and polysaccharides from seaweed. Background technique [0002] Seaweed (Algae or Seaweeds) is an important part of marine biological resources. It is the original producer of organic matter and natural enricher of inorganic matter in the ocean. It is rich in amino acids, cellulose, vitamins, minerals, trace elements and other nutrients , and proteins, polysaccharides, lipids, terpenes, sterols, alkaloids, saponins, enzymes and many other active substances with novel structures and unique effects. [0003] The polyunsaturated fatty acids (PUFAs) rich in algae have strong biological activity, can promote the development of the nervous system and visual system, prevent and treat cardiovascular diseases, and have anti-cancer, anti-inflammatory, and anti-oxidation effects. The content of PUFAs i...
