Abstract

The invention discloses an extraction process of chondrus crispus, which comprises the following steps: washing and chopping chondrus crispus, then adding the chondrus crispus into an ethanol water solution, stirring at a constant temperature, and filtering to obtain a first extracting solution and first filter residues; freezing the first filter residue, crushing the first filter residue into fine powder, putting the fine powder into ethanol, carrying out ultrasonic treatment for 0.5-1 hour, then adding distilled water containing alkaline substances, carrying out secondary ultrasonic treatment for 2-4 hours, and filtering to obtain a second extracting solution and second filter residue; adding the second filter residues into distilled water, performing constant-temperature cooking for 2-3h, and then performing natural cooling and filter pressing to obtain a third extracting solution and third filter residues; mixing the first extracting solution, the second extracting solution and the third extracting solution, stirring at constant temperature for 2-5 hours to obtain a concentrated solution, and then performing reduced pressure distillation and freeze drying on the concentrated solution to obtain the chondrus crispus extract. According to the method, the problem of residue of the existing chondrus crispus filter residues is solved, the extraction amount is increased by combining alcohol extraction and water extraction, and full extraction of active substances is achieved.

Description

technical field [0001] The invention belongs to the technical field of extraction, and in particular relates to an extraction process of corrugated carrageenan. Background technique [0002] Crinkle carrageenan extract is one of the natural macromolecular raw materials allowed to be used in the national skin care or cosmetic raw material catalogue. With high water solubility, it can promote skin metabolism, stimulate fibroblasts to produce more colloid, elastic hard protein and mucopolysaccharide, etc., promote the growth of epidermal cells, promote metabolism, and prevent skin aging. All in all, wrinkle carrageenan extract has the functions of detoxification, deep cleaning, removal of dead skin cells, firming, moisturizing and lightening of wrinkles, etc., and the skin becomes smooth and radiant immediately after use. At present, the extraction process of carrageenan is mainly based on alkali extraction, but the residue after extraction still contains a lot of active subst...
