Embodiment 1
[0012] A method for extracting unsaturated fatty acids from Enteromorpha, the method comprises the following steps:
[0013] A, the Enteromorpha powder is obtained after draining, dehydrating, drying and pulverizing;
[0014] B, adding Enteromorpha powder into petroleum ether and soaking for 24h, the mass volume ratio of Enteromorpha powder and petroleum ether is 1g: 10mL, reflux in 50~60°C water bath for 3h, filter and centrifuge to obtain supernatant;
[0015] C, add potassium hydroxide, ethanol saponification solution in the supernatant;
[0016] D. Add 2mol / L hydrochloric acid solution after saponification, adjust the pH value to 4, and the filtrate after suction filtration is unsaturated fatty acid.

The invention discloses a method for extracting unsaturated fatty acid from sea grass, which comprises the following steps: draining sea grass, dewatering, drying, and pulverizing to obtain sea grass powder; adding the sea grass powder into petroleum ether, and soaking for 24 hours; refluxing in water bath, filtering, and centrifuging to obtain the supernatant; and then, adding a saponifying solution into the supernatant, adding a hydrochloric acid solution after the saponification is finished, and regulating the pH value, thus obtaining the unsaturated fatty acid. According to the invention, sea grass is used as raw material, the waste is changed into valuable substances, the process is simple, the investment is low and important economic benefits can be achieved.
Description
technical field [0001] The invention belongs to the technical field of fatty acid extraction, and in particular relates to a method for extracting unsaturated fatty acid from enteromorpha. Background technique [0002] At present, the eutrophication of seawater is increasing day by day, and the outbreak of Enteromorpha is becoming more and more frequent and serious. Therefore, how to use Enteromorpha resources and turn waste into treasure has become an important development direction of science and technology. Enteromorpha is rich in various nutrients and contains a large amount of unsaturated fatty acids, but there is currently no extraction method for unsaturated fatty acids in Enteromorpha at home and abroad. Contents of the invention [0003] To solve the above technical problems, the object of the present invention is to provide a method for extracting unsaturated fatty acids from Enteromorpha. [0004] The present invention adopts following technical scheme: extract...
