Embodiment 1
[0029] 1) Take 1 kg of ginger and cut into shreds, add 15 times the amount of NaOH solution for pre-treatment; use a flash extractor to perform wall-breaking treatment at a voltage of 220V for 3 minutes to obtain a wall-breaking slurry.
[0030] 2) Add a compound enzyme composed of 0.3% cellulase, 0.1% turmeric amylase and 1.0% turmeric papain by weight of the broken wall liquid to the broken wall slurry and adjust the pH to 3. After 3 hours of enzymolysis , high temperature inactivation treatment to obtain enzymatic hydrolysis solution.
[0031] 3) Add the enzymatic hydrolysis solution to sodium salicylate alcohol solution, homogenize at 6000r / min for 6min, and then extract twice by ultrasonic to obtain curcumin extract.
[0032] 4) Concentrate the extract to a paste, apply Diaion HP-10 macroporous resin, elute with 30% volume percent acetone-glacial acetic acid, collect the eluate and remove the solvent to obtain crude curcumin;
[0033] 5) Use the mixed solvent ethanol and...

Abstract
The invention relates to a method for extracting curcumin from fresh ginger. According to the method, fresh ginger raw materials are directly used without drying, an extraction process adopts wall breaking of a flash extraction device, compound enzyme enzymolysis and an ultrasonic-assisted sodium salicylate ethanol solution extraction method, a technique combined wall breaking of a flash extraction device with compound enzyme enzymolysis greatly improves extraction efficiency, most of impurities in solution can be remained in mother solution through crystallization, high-purity crystals can beacquired through filtering and washing, a HPLC (high performance liquid chromatography) detects that purity can reach 90% or more after crystallization, and the HPLC detects that the purity can reach97% or more after recrystallization.
Description
technical field [0001] The invention relates to an extraction process, in particular to a method for extracting curcumin from ginger. Background technique [0002] Turmeric is the dry rhizome of Curcumalonga L., a plant in the ginger family, which has the functions of promoting qi and relieving pain, promoting menstrual flow and breaking blood, dispelling wind and treating numbness. In recent years, pharmacological studies at home and abroad have found that turmeric plants have various functions such as preventing and treating cancer and protecting brain nerves, so they have attracted much attention. [0003] Curcumin, commonly known as curcumin, is mainly derived from the rhizome of turmeric, a plant of the genus Curcuma longa in the ginger family. A large number of studies have proved that curcumin has various pharmacological effects such as anti-oxidation, anti-inflammation, anti-cancer, scavenging free radicals, anti-microbial, protecting cardiovascular and cerebrovascu...
