| titleOfInvention | Method for extracting nostoc proteins |
| abstract | The invention relates to a nostoc protein extraction method, which comprises the steps of extracting nostoc phycobiliprotein by pure water, sequentially extracting alkali-soluble protein from filter residues by using a sodium hydroxide solution, extracting alcohol-soluble protein by using an ethanol solution, extracting salt-soluble protein by using a sodium chloride solution, mixing the obtained nostoc phycobiliprotein crude extract, the alkali-soluble protein crude extract, the alcohol-soluble protein crude extract and the salt-soluble protein crude extract, performing ultrafiltration impurity removal by using a ceramic membrane, performing ultrafiltration concentration by using an organic membrane, and performing freeze drying to obtain nostoc protein. Compared with the existing repeated freeze-thawing method, the method greatly simplifies the operation difficulty, overcomes the harsh conditions, has the extraction rate far superior to that of the prior art, and can extract about 70 percent of protein in the nostoc sphaeroides. Compared with the prior art that phycoerythrin and phycocyanin are extracted singly or phycobiliprotein with more components is extracted, the comprehensive nostoc sphaeroides protein extracted by the method can be used as a comprehensive nutrient to be added into industrial food and medicines, and has wide application prospect. |
