Embodiment 1

[0049]Clean the ginger with clean water, put it in a -20 freezer for 10 hours, take out the ginger and put it in the crushing equipment for 60 seconds, transfer the resulting crushed product to a beaker and other containers as soon as possible, add 95 % ethanol and ethylene glycol dimethyl ether mixture, in which the volume ratio of 95% ethanol to ethylene glycol dimethyl ether is 3:1, intermittent ultrasonication under ice bath conditions, that is, ultrasonic 5min, stop 1min. A total of 6 cycles were performed. The resulting extract was vacuum filtered. Use spray drying equipment to dry below 40°C. That is, a powdered extract is obtained.

Embodiment 2

[0051] Clean the ginger with tap water, put it in a -20 freezer for 8 hours, take out the ginger and put it in the crushing equipment for 90 seconds, transfer the resulting crushed product to a beaker and other containers as soon as possible, add 95 % ethanol and ethylene glycol dimethyl ether mixture, in which the volume ratio of 95% ethanol to ethylene glycol dimethyl ether is 5:1, intermittent ultrasonication under ice bath conditions, that is, ultrasonic 5min, stop 1min. A total of 6 cycles were performed. The resulting extract was vacuum filtered. Use spray drying equipment to dry below 40°C. That is, a powdered extract is obtained.

Embodiment 3

[0053] Clean the ginger with tap water, put it in a -20 freezer for 10 hours, take out the ginger and put it in the crushing equipment for 60 seconds, transfer the resulting crushed product to a beaker and other containers as soon as possible, and add 95% of the mass-volume ratio of 1:5 A mixture of ethanol and ethylene glycol dimethyl ether, in which the volume ratio of 95% ethanol to ethylene glycol dimethyl ether is 2:1, intermittently sonicate in an ice bath, that is, sonicate for 5 minutes and stop for 1 minute. A total of 8 cycles were performed. The resulting extract was vacuum filtered. Use spray drying equipment to dry below 40°C. That is, a powdered extract is obtained.

Abstract

The invention provides a fresh ginger extracting method. The fresh ginger extracting method is characterized by including the steps that after being washed, fresh ginger is frozen for 8 hours or more at the temperature of -20 DEG C; the ginger is smashed through a smashing device, and a mixture of 95% ethyl alcohol and glycol dimethyl ether is added, wherein the volume ratio of the 95% ethyl alcohol to the glycol dimethyl ether is 1:1 to 50:1; intermittent ultrasonic extraction is carried out for 30 min to 120 min under the ice bath condition; vacuum suction filtration and spray drying are carried out, and extract is obtained. The method is easy to operate, feasible and suitable for industrial production, gingerol ingredients are prevented from being damaged to the maximum degree, and the gingerol extracting ratio is increased.

Description

technical field [0001] The invention relates to a ginger extract containing high-quality gingerol and a preparation process thereof, belonging to the field of biotechnology. Background technique [0002] Ginger is the rhizome of the perennial herb ginger (Zingiber Officinale Roscoe). It is a kind of rhizome spice seasoning widely planted in the world. It is also a traditional medicinal and edible plant. The effect of returning to yang and dredging the pulse, drying dampness and eliminating phlegm. [0003] Modern medical research shows that ginger has anticoagulation, anti-oxidation, anti-tumor, boosting blood pressure, strengthening the heart, lowering blood fat, anti-atherosclerosis, protecting gastric mucosa, protecting the liver and gallbladder, anti-inflammatory, antitussive, anti-dizziness and anti-emetic, on the central nervous system Neuroinhibition and other effects. [0004] Gingerol (gingerol) is the main active substance in ginger, including more than ten compo...
