Problems solved by technology

At present, the main methods for extracting zingerone from ginger include steam distillation, solvent extraction, pressing, carbon dioxide supercritical extraction, etc., but these methods still have incomplete extraction of zingerone, low transfer rate, and difficult extraction process. Zingerone is easy to oxidize and degrade, making technical problems such as low purity urgently need to be solved

Abstract

The invention provides a method for extracting and separating zingerone from ginger, which is realized by taking the fresh ginger as a raw material through the steps of pretreatment, ultrasonic extraction, ultrafiltration, purification, vacuum concentration and the like. In the ultrasonic extraction process, lauryl sodium sulfate and L-cysteine also need to be added into the ginger; the mass ratio of the ginger to the L-cysteine is 100: (3-6), the lauryl sodium sulfate needs to be prepared into a solution with the mass fraction of 0.5%-1.0% by using purified water, and the mass ratio of the ginger to the lauryl sodium sulfate solution is 1: (1-3). The extraction transfer rate is high and reaches up to 79.1%, the whole extraction system is still alkalescent in the presence of L-cysteine due to the introduction of the weakly acidic L-cysteine dissolved in water, the specific adding mode of the L-cysteine and the existence of lauryl sodium sulfate, the zingerone can be dissolved more easily, the zingerone is not degraded in the extraction process, and the purity of the extracted zingerone reaches 98% or above.

Description

technical field [0001] The invention relates to the technical field of food, in particular to a method for extracting and separating zingerone from ginger. Background technique [0002] Ginger, the name of traditional Chinese medicine. It is the fresh rhizome of ginger, a perennial herb of the Zingiberaceae family. It is also known as ginger root, Bailayun, Gouzhuangzhi, Yindixin, Yanliang boy, and fresh ginger. The rhizome (dry ginger), cork (ginger skin) and leaves (ginger leaves) of ginger can be used as medicine. Ginger is pungent in taste and slightly warm in nature. Return lung, spleen, stomach warp. It has the effects of relieving the exterior and dispelling cold, warming the middle to stop vomiting, warming the lungs and relieving cough, and detoxifying. It is often used for wind-cold cold, spleen-stomach cold syndrome, stomach-cold vomiting, lung-cold cough, and detoxification of fish and crabs. [0003] Ginger contains a variety of minerals and vitamins, as wel...
