Abstract

The invention discloses a method for continuously extracting curcuma oil and curcumin, the method comprises the following steps: 1) preparation of turmeric medicinal material powder: cleaning and drying a turmeric raw material, crushing, and sieving with a 60-mesh sieve to prepare the turmeric medicinal material powder with the water content of 6-10%; 2) extraction of curcuma oil: mixing and extracting the curcuma medicinal material powder and a first solvent to obtain a curcuma oil extracting solution and filter residues, wherein the filter residues are deoiled curcuma powder; (3) preparing turmeric extract: adding the deoiled turmeric powder and a second solvent into a continuous ultrasonic extraction device to obtain a curcumin extracting solution, and concentrating to remove the solvent to obtain the turmeric extract; 4) removing a surfactant: eluting the turmeric extract with distilled water to remove the surfactant; and 5) preparation of curcumin powder: drying the turmeric extract to obtain the curcumin powder. The method realizes continuous extraction of curcuma oil and curcumin, has a good extraction effect, and can realize large-scale industrial continuous production.

Description

technical field [0001] The invention relates to a method for continuously extracting turmeric oil and curcumin. Background technique [0002] Turmeric belongs to the genus Curcuma (Curcuma) of the ginger family. The dry rhizome of the perennial herb Curcuma longa (Curcuma longa L.) is widely cultivated in tropical areas of Asia. In my country, it is mainly distributed in Southwest China, Guangxi, Guangdong, Hebei, Jiangxi, Zhejiang and other places Its main ingredients are curcumin and turmeric oil. [0003] Turmeric oil accounts for more than 7% of the total content of turmeric rhizomes, mainly containing curcumone, zingiberene, borneol, etc. Turmeric oil is often used in food spices and pigments, and used in traditional Chinese medicine for detoxification, muscle growth, hemostasis, and digestion. Curcumin is a rare diketone-containing pigment in the plant kingdom, and its content in turmeric rhizomes is about 3-6%. Curcumin is mainly used in food production for coloring s...
