Problems solved by technology

The disadvantages of this method are: the time is too long, the yield is low, and the selenium polysaccharide is not utilized
The disadvantage of this method is: there is no description of the yield, it is relatively extensive, and the hygiene is difficult to meet the requirements
[0004] Other domestic literatures about the extraction of selenium polysaccharides, selenoproteins or organic selenium are generally theoretical studies, and it is difficult to carry out industrial production, such as the separation, purification and spectral analysis of selenium polysaccharides from broken rice chestnuts, the analysis of selenium forms in selenium-enriched wolfberry, and natural production. Analysis of volatile substances and selenium occurrence forms in cabbage, etc.

Abstract

The invention discloses a method for extracting purely natural plant organic selenium. In the specific method, smashing and soaking in clear water are performed, so that plant selenium can be better dissolved out. Heating and extraction are performed on the basis. Compared with the prior art, a product or the method disclosed by the invention has the advantages of more complete extraction, lower time consumption and relatively saving in water. A process for soaking in clear water for 30 minutes and a process for extracting with stirring at the temperature 80 DEG C for 1 hour are performed, so that 80 percent of plant selenium in a plant can be extracted by extracting with stirring at the temperature 90 DEG C for 1 hour.

Description

technical field [0001] The invention relates to an extraction method of organic selenium, in particular to an extraction method of pure natural plant organic selenium. Background technique [0002] At present, there are various extraction methods for organic selenium, among which the most important extraction method is: extracting selenoproteins from selenium-enriched edible fungi. It needs to be controlled at 60°C-62°C, the ratio of solid to liquid (W / V) is controlled at 1:24-69, the number of extractions is 2 times, and the extraction time is 8 h. Under these conditions, the yield of protein is only 30.17%. . The disadvantages of this method are: the time is too long, the yield is low, and the selenium polysaccharide is not utilized. [0003] The patent No. 99112755.2 published by the State Patent Office: the method of extracting natural organic selenium, first of all, it is necessary to use fresh wild vegetables or whole plants of wild Amaryllidaceae as raw materials fo...
