Problems solved by technology

These technologies require a lot of energy consumption, and they need to be operated under high temperature conditions for a long time, which is not suitable for industrial production.
[0008] There are following problems in the above-mentioned existing patented technology and research: (1) utilize high-concentration ethanol (mostly 80% and above) to carry out high temperature and long-term extraction of gingerol, such as Soxhlet extraction using 95% ethanol at close to 100°C Extract 5~6h, do not consider safety factor, there is potential safety hazard in industrial production; (2) the purification technology of gingerol is complicated, and needs to add multiple organic solvents such as ether, ethyl acetate

Embodiment 1

[0052] Select intact and undamaged turmeric, clean it, and slice it with a slicer. The thickness of the ginger slices is 2-3 mm. Dry the ginger slices. The water content of the dried ginger slices is about 7%. Grind them with a grinder and pass through a 40-mesh sieve. dried ginger powder;

[0053] Take 5g of prepared freeze-dried ginger powder and add 80% ethanol solution, the ratio of solid to liquid (g / ml) is 1:20, stir and mix evenly, add 0.1M tartaric acid solution dropwise, adjust the pH to 4.0, and make acidic ginger powder dispersion;

[0054] Put the acidic ginger powder dispersion into figure 2 The pulsed electric field treatment system shown in the figure is sequentially transported to the high-voltage pulsed electric field treatment chamber 5 through the pump 1 and the circulating condensing device 3 for pulsed electric field treatment. The flow rate of the acidic ginger powder dispersion is adjusted to 1.0t / h by the flowmeter 2, and the treatment temperature is...

Abstract

The invention discloses a pulsed electric field treatment preparation method of gingerol with high content of 6-gingerol. The method mainly comprises the following steps: (1) cleaning fresh yellow ginger, slicing, drying ginger slices, crushing by a crusher, and sieving to obtain dried ginger powder; (2) adding dried ginger powder into ethanol, uniformly stirring, and adding tartaric acid to adjust the pH value to obtain a dispersion liquid; (3) pumping the ginger powder dispersion liquid into a pulsed electric field treatment chamber for pulsed electric field treatment; (4) carrying out three-phase separation on the treated ginger powder dispersion liquid to obtain supernatant, removing impurities by passing through a membrane to obtain clarified filtrate, and carrying out vacuum decompression concentration on the filtrate until no ethanol is screwed out, thereby obtaining the gingerol concentrate with high content of 6-zingiberol. According to the method, a pulsed electric field technology is adopted, under the catalytic action of organic acid, part of the 6-gingerol is rapidly converted into the 6-gingerol under the low-temperature condition, so that the gingerol with high content of the 6-gingerol is prepared, and the method is short in time, efficient, simple to operate and safe in production.

Description

technical field [0001] The invention relates to gingerol, in particular to a method for preparing gingerol with high content of 6-shogaol, and belongs to the field of extraction and preparation of bioactive components. Background technique [0002] Ginger is pungent, slightly warm, and returns to the Lung, Spleen and Stomach Meridian. It has the effects of sweating and relieving the exterior, warming the middle to relieve vomiting, warming the lungs to relieve cough, and detoxification. "Compendium of Materia Medica" contains it: "The raw use diverges, and the cooked use is neutral. Ginger has been considered as a resource for both medicine and food since ancient times. It can not only be used as a seasoning for cooking, but it is one of the oldest spices in the world. Moreover, it is a traditional Chinese medicine material and has the reputation of medicinal "gold". Ginger can be used for the prevention and treatment of many diseases, including arthritis, colds, palpitation...
