Abstract

The invention relates to a method for extracting effective components of mulberry. The method comprises the steps of (1) washing mulberry for 2-3 times by clear water, draining water, then pulverizing the mulberry to obtain mulberry slurry, and freezing and storing at -2 DEG C for use; (2) unfreezing the frozen mulberry slurry in the step (1) and adding extracting solution into the frozen mulberry slurry to leach for 1-3 hours at the temperature condition of 50-70 DEG C, and then filtering the solution to obtain leach liquor and filter residue; (3) adding the extracting solution to the filter residue to leach for 1-3 hours at the temperature condition of 50-70 DEG C, and then filtering to obtain secondary leach liquor; and (4) merging twice leach liquor, putting the leach liquor into a rotary evaporator, evaporating and recovering the extracting solution, and drying the product in the evaporator under a vacuum condition to obtain mulberry red pigment. The extracting method disclosed by the invention is simple and convenient, and easy to operate; the extracting solution can be effectively recovered; and the resource is saved while the extracted mulberry red pigment is high in productivity, and the application value is also improved.

Description

technical field [0001] The invention relates to an extraction method, in particular to an extraction method of active ingredients of mulberries, and belongs to the field of extraction technology. Background technique [0002] Mulberry fruit is rich in active protein, vitamins, amino acids, carotene, minerals, resveratrol, anthocyanins and other ingredients. Its nutrition is 5-6 times that of apples and 4 times that of grapes. It has various effects. Known as "the best health fruit in the 21st century" by the medical profession. Eating mulberries often can significantly improve human immunity, and has the effects of delaying aging and beautifying the skin. [0003] The red pigment in mulberry fruit is widely used in candy, jelly, haw jelly, fruit wine and beverages. Because this kind of red pigment is a natural red pigment, it has good safety, high coloring property, strong water solubility, and is beneficial to the human body. Absorption. But the extraction method of trad...
