| titleOfInvention | Method for extracting roselle calyx red pigment |
| abstract | The invention relates to a method for extracting a roselle calyx red pigment, which relates to a method for extracting a roselle calyx red pigment, the method comprises the following steps: 1) dehydrating and preserving a fresh roselle calyx raw material through a heat pump; 2) extracting the dehydrated raw material through water; 3) extracting the pigment, through rough filtering and filter membrane fine filtering, separating and purifying a pigment extract,4) concentrating the pigment extract through a nanofiltration membrane, circularly using the nanofiltrated water for extracting the raw material; and 5) spraying and drying a pigment concentrated solution to obtain the products. Compared with the prior art, the method for extracting the roselle calyx red pigment has the advantages of energy conservation and environmental protection, and the obtained product has high quality and reasonable price. |
