Abstract

The invention relates to a natural pigment curcumin product and a production process thereof, and belongs to the technical field of agricultural product deep processing. Turmeric rhizomes are used as raw materials; an eutectic solvent prepared from natural ingredients is an extracting agent; the curcumin is highly and selectively extracted by utilizing the characteristic of the natural eutectic solvent; the extraction efficiency is improved through ultrasonic treatment. After the extraction, water is used as a solvent; the curcumin is selectively precipitated by an anti-solvent method; sediments are subjected to centrifugation and vacuum drying; the high-purity natural curcumin product is prepared. The method has the advantages that the nontoxic and natural eutectic solvent and the water are used as the extracting agent and a precipitating agent, the production process is simple, efficient, safe and green; the defect that the traditional curcumin production needs a large number of noxious organic solvents and the complicated column separation process is overcome.

Description

technical field

[0001] The invention belongs to the field of food processing, and relates to a high-purity natural pigment curcumin product and a preparation method thereof. Background technique

[0002] Curcumin is one of the active components of the Chinese medicinal material turmeric (Curcuma longa L.), and is the main component of turmeric to exert its pharmacological effects. Curcuminoids mainly include curcumin (C 21 h 20 o 6 , accounting for about 70%), demethoxycurcumin (C 20 h 18 o 5 , accounting for about 15%), dedimethoxycurcumin (C 19 h 16 o 4 , accounting for about 10%), is a rare diketone colored substance in nature. Curcumin is one of the main bioactive components of turmeric plants. As a natural pigment, curcumin has strong coloring power, is safe and non-toxic, and can be widely used as a coloring agent in food products. It is regulated by FAO, WHO and my country's GB2760-2014 One of the most safe natural pigments. In addition, curcumin also has ph...
