1. A production process of zanthoxylum oil is characterized by comprising the following steps;

(1) selecting dry pepper and vegetable oil;

(2) parching semen Brassicae campestris at 60-100 deg.C for 10-60 min, cooling to 50-80 deg.C, adding dried fructus Zanthoxyli 20-40% of the weight of semen Brassicae campestris, and holding for 15-20 min to obtain mixed oil material;

(3) adding the mixed oil after mixed frying into an oil presser, keeping the temperature at 90-150 ℃, and preliminarily pressing out the zanthoxylum oil; (4) primarily filtering the primarily squeezed zanthoxylum oil by using a filter screen to filter most of impurities;

(5) introducing the primarily filtered zanthoxylum oil into a vacuum filter for secondary filtering, wherein the oil temperature is kept at 75-105 ℃ during the secondary filtering, so as to improve the filtering efficiency;

(6) adding the zanthoxylum oil subjected to vacuum filtration into a centrifugal oil filter, and performing rotary precipitation and filtration again to obtain the zanthoxylum oil.

2. The production process of zanthoxylum oil according to claim 1, characterized in that the dried zanthoxylum is zanthoxylum in which 65-75% of moisture of fresh zanthoxylum is removed by sunlight solarization.

3. The process for producing zanthoxylum oil according to claim 1, wherein the pressing temperature is controlled at 100-110 ℃.

Technical Field

The invention relates to the technical field of food processing, in particular to a production process of zanthoxylum oil.

Background

The pericarpium zanthoxyli is a common seasoning spice, the content of various volatile aromatic substances in the pericarpium zanthoxyli is as high as 9 percent, and the pericarpium zanthoxyli not only is a good raw material for refining and manufacturing high-grade edible essence, but also is a common edible seasoning. The fructus Zanthoxyli has effects of promoting appetite, invigorating spleen, and improving body constitution. At present, the Chinese prickly ash is favored by many people, and the price is doubled. The existing zanthoxylum oil production method includes chemical separation method, water boiling distillation method and other methods. The chemical separation method mainly uses ether and petroleum ether as chemical reagents to extract the zanthoxylum oil, and the zanthoxylum oil extracted by the method has the defects of chemical reagent residue, impure quality of aromatic oil and heavy peculiar smell.

The existing processing method of zanthoxylum oil in non-zanthoxylum producing areas and non-picking seasons is to extract aromatic oil and ephedrine of fresh zanthoxylum in advance and then blend with rape oil, chemical reagents such as emulsifier, stabilizer and the like are added in the blending process, thus being not green and environment-friendly, and peculiar smell can be generated after a long time.

Disclosure of Invention

The invention aims to solve the defects and provides the production process of the zanthoxylum oil, which has high production efficiency, wide raw material source, low cost and pure taste.

The technical scheme provided by the invention is a production process of zanthoxylum oil, which comprises the following steps;

(1) selecting dry pepper and vegetable oil;

(2) parching semen Brassicae campestris at 60-100 deg.C for 10-60 min, cooling to 50-80 deg.C, adding dried fructus Zanthoxyli 20-40% of the weight of semen Brassicae campestris, and holding for 15-20 min to obtain mixed oil material;

(3) adding the mixed oil after mixed frying into an oil presser, keeping the temperature at 90-150 ℃, and preliminarily pressing out the zanthoxylum oil; (4) primarily filtering the primarily squeezed zanthoxylum oil by using a filter screen to filter most of impurities;

(5) introducing the primarily filtered zanthoxylum oil into a vacuum filter for secondary filtering, wherein the oil temperature is kept at 75-105 ℃ during the secondary filtering, so as to improve the filtering efficiency;

(6) adding the zanthoxylum oil subjected to vacuum filtration into a centrifugal oil filter, and performing rotary precipitation and filtration again to obtain the zanthoxylum oil.

The production process of the zanthoxylum oil comprises the following steps: the dried pepper refers to pepper with 65-75% of water of fresh pepper removed by sunlight solarization.

The production process of the zanthoxylum oil comprises the following steps: the pressing temperature is controlled at 100-110 ℃.

The invention has the beneficial effects that: the production process is shortened, the production efficiency is improved, the raw material application range is wide, the cost can be effectively reduced, and the original taste and flavor and rich nutrient components of the pepper are retained to the maximum extent.
