| titleOfInvention | Method for extracting gardenia yellow pigment |
| abstract | A method for extracting gardenia yellow pigment comprises the following steps: removing peel of fructus Gardeniae, sun drying, grinding into powder, sieving, and extracting with water; performing solid-liquid separation on the leaching liquor to obtain a first extracting solution, then adding water into the residual solid mixture for secondary extraction under ultrasonic waves, and performing solid-liquid separation on the second leaching liquor to obtain a second extracting solution; mixing the two extractive solutions, adding pectase and diatomaceous earth, stirring, standing, filtering with filter membrane, and microfiltering to obtain microfiltrate; purifying the micro-filtrate by using petroleum ether to obtain a purified extracting solution; and (3) performing weight reduction and concentration on the purified extracting solution through a reverse osmosis membrane, separating the gardenoside from the concentrated pigment solution through membrane separation to obtain a separation solution, and performing vacuum freeze drying. The extraction method can efficiently extract high-price gardenia yellow pigment from gardenia jasminoides fruits, and the extracted gardenia yellow pigment is not easy to generate green change and gray change and has long storage time. |
