Production method of zanthoxylum oil

Abstract

The invention discloses a production method of zanthoxylum oil. The method comprises the following steps: selecting dried zanthoxylum and vegetable oil; baking and sauting the vegetable oil for 10-60 minutes at 60-100 DEG C, adding the dried zanthoxylum accounting for 6-12wt% of the vegetable oil when cooling the vegetable oil to 50-80 DEG C and maintaining for 2-10 minutes so as to obtain mixed oil; adding the mixed oil obtained in the mixing and sauting manner into an oil presser, maintaining the temperature within 70-100 DEG C and performing initial squeezing so as to obtain the zanthoxylum oil; performing preliminary filtration on the initially-squeezed zanthoxylum oil by using a filter screen so as to filter a majority of impurities; introducing the zanthoxylum oil subjected to the preliminary filtration into a vacuum filter; performing filtration on zanthoxylum oil again under the condition that the oil temperature is maintained within 75 DEG C to 105 DEG C so as to improve the filtration efficiency; adding the zanthoxylum oil subjected to the vacuum filtration into a centrifugal oil filter and performing rotating precipitation and filtration again, thereby obtaining the zanthoxylum oil. The method is high in production efficiency, wide in raw material resource, low in cost and pure in zanthoxylum oil taste.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a production method of prickly ash oil. [0002] Background technique [0003] Zanthoxylum bungeanum peel is a commonly used seasoning spice. The content of various volatile aromatic substances in Zanthoxylum bungeanum peel is as high as 9%. It is not only a good raw material for refining and making high-grade food flavors, but also a standing edible condiment. Zanthoxylum bungeanum has the functions of appetizing, invigorating the spleen and strengthening the body. At present, Zanthoxylum bungeanum has been favored by many people, and its value has doubled. The existing Zanthoxylum bungeanum oil preparation method has methods such as chemical separation method, boiling distillation method. The chemical separation method mainly uses the chemical reagents of ether and petroleum ether to extract the Zanthoxylum bungeanum aromatic oil. The Zanthoxylum bungeanum oil extrac...

Problems solved by technology

However, due to the use of wet Zanthoxylum bungeanum to process Zanthoxylum bungeanum oil, this method is limited by the place of origin and picking season, and it is difficult to produce in non-main producing areas and non-picking seasons of Zanthoxylum bungeanum. At the same time, it has the disadvantage of high material transportation and storage costs.

Due to the high water content of wet pepper, the water content of the produced pepper oil is also high, and the acid value is high, which cannot guarantee the stability of the quality of the pepper oil.

Existing non-Prickly apricot origin, non-picking season Zanthoxylum bungeanum oil processing method all is to extract the aromatic oil and cannabinoid of Zanthoxylum bungeanum in advance and then use vegetable oil deployment, all will add chemical reagents such as emulsifier, stabilizer in the deployment process, both Not green and environmentally friendly, there will be peculiar smell after a long time
