Industrial preparation method of Chinese prickly ash oil

Abstract

The invention discloses an industrial preparation method of Chinese prickly ash oil. The method comprises the following steps: drying and stir-frying Hanyuan Chinese prickly ash ripe peel used as a raw material, crushing the dried and stir-fried raw material to form Chinese prickly ash powder, immersing the Chinese prickly ash powder in anhydrous ether, filtering the obtained solution to obtain afiltrate, performing hot refluxing on the filtrate to recover ether and obtain initial Chinese prickly ash oil, and drying the initial Chinese prickly ash oil by using anhydrous sodium sulfate to obtain the Chinese prickly ash oil. The Chinese prickly ash oil is extracted through adopting anhydrous ether immersion and purification processes, the prepared Chinese prickly ash oil maximally retains concentrated extract having most best smell, delicious taste and spicy taste in Chinese prickly ash seeds, and the ether used for the immersion is recovered by hot refluxing. The method retains the original spicy and delicious flavor of Chinese prickly ash, and has the advantages of low device cost, simple extraction process and high extraction purity.

Description

technical field [0001] The invention relates to an industrial preparation method of Zanthoxylum bungeanum essential oil, in particular to the preparation of Zanthoxylum bungeanum essential oil in an industrial production process, and belongs to the technical field of Zanthoxylum bungeanum oil production. Background technique [0002] Zanthoxylum bungeanum is a plant of the Rutaceae family. It has the functions of warming and helping yang, dispelling cold and drying dampness, promoting qi and relieving pain, killing insects and relieving itching, and anti-oxidative flavoring. It is not only a food flavoring spice with hemp flavor, but also a traditional Chinese medicine , has a wide range of applications in the field of food additives, known as one of the "eight flavors". At present, there are three main methods for preparing pepper oil: [0003] 1) Steam distillation method, such as CN201210464996.2 (method for producing pepper oil, 2012.11.16), has the advantages of simple...

Problems solved by technology

[0003] 1) The steam distillation method, such as CN201210464996.2 (method for producing pepper oil, 2012.11.16), has the advantages of simple process and low cost of use, but the distillation process may cause changes in the properties and aroma of pepper oil, affecting The quality of pepper oil

[0004] 2) Volatile solvent extraction method, using volatile solvents, such as petroleum ether, alcohol, benzene, etc., to process the pepper raw materials to obtain an extract solution, that is, an oil-water mixture, and then separate to obtain pepper oil. In the actual operation process However, because the introduction of volatile solution will easily lead to residual petroleum ether, benzene and other harmful substances in the pepper oil, it is not easy to be used for the production of food-grade pepper oil
