| titleOfInvention | A kind of extraction method of turmeric saponin |
| abstract | The invention discloses a method for extracting turmeric saponin, belonging to turmeric saponin extraction technology, comprising the following steps: (1) accumulating fresh turmeric indoors, naturally fermenting for 3 to 5 days, sieving, removing roots, cleaning and crushing, Obtain turmeric liquid, or make turmeric powder from dried turmeric; (2) put turmeric liquid or turmeric powder in a hydrolysis tank, add sulfuric acid and phosphoric acid and heat to boiling for 30-40 minutes to obtain a hydrolyzate; (3) hydrolyze The solution is filtered through a plate and frame filter, and the filtered residue is washed with acid and dried to obtain a saponin hydrolyzate; (4) sequentially extracting, separating, crystallizing, filtering, and drying the saponin hydrolyzate to obtain turmeric saponin. The present invention hydrolyzes turmeric through the sulfuric acid and phosphoric acid whose concentrations are respectively 98% and 85%. On the one hand, the rate of hydrolysis is improved, which is beneficial to the opening of the glycosidic bond of saponin in turmeric. Reduce the yield of turmeric saponin; in addition, the use of phosphoric acid reduces the amount of sulfuric acid, and phosphoric acid can be recovered in subsequent processes; the reduction of sulfuric acid reduces the difficulty of subsequent treatment processes and reduces the operating load of sewage treatment plants. |
