Technical Field

The invention relates to the technical field of food processing, in particular to a production method 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. Generally, the method for picking the zanthoxylum is to obtain fresh zanthoxylum juice after mechanically breaking the peel and then to obtain zanthoxylum oil by mixing and soaking the zanthoxylum oil. However, the method adopts silver pheasant wet zanthoxylum bungeanum to process zanthoxylum oil, so the method is limited by production areas and picking seasons, is difficult to produce in non-zanthoxylum primary production areas and non-picking seasons, and has the defect of high material transportation and storage cost. Because the moisture content of the wet zanthoxylum is large, the produced zanthoxylum oil has large moisture content and high acid value, and the stability of the quality of the fresh zanthoxylum oil can not be ensured. 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 a production method of zanthoxylum oil with high production efficiency, raw material sources, low cost and pure taste.

The production process of kinds of pricklyash oil includes the following steps of (1) selecting dry pricklyash peel and vegetable oil material;

(2) baking and frying: parching vegetable oil at 60-100 deg.C for 10-60 min, cooling to 50-80 deg.C, adding dried fructus Zanthoxyli 6-12% of vegetable oil, and holding for 2-10 min to obtain mixed oil;

(3) squeezing: adding the mixed oil after mixing and frying to an oil presser, keeping the temperature at 70-100 ℃, and preliminarily pressing out the zanthoxylum oil; (4) primary filtering: primarily filtering the primarily squeezed zanthoxylum oil by using a filter screen to filter most of impurities;

(5) vacuum filtration: introducing the primarily filtered Zanthoxylum oil into vacuum filter for secondary filtration, wherein the oil temperature is maintained at 75-105 deg.C to improve filtration efficiency. (6) Centrifugal filtration: 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.

In the production method of the zanthoxylum oil, the dried zanthoxylum is pure in variety and superior in quality in order to better improve the quality.

The production process of kinds of prickly ash oil includes selecting vegetable oil preferably from rape seed oil or soybean oil.

The production process of kinds of prickly ash oil includes squeezing at 85-95 deg.c.

Compared with the prior art, the method has the advantages and effects that the production process is shortened by adopting the direct squeezing of the mixed dry pepper and the oil material, the daily output is improved, 2 tons of pepper oil can be produced by 1 set of equipment in a day, the production efficiency is high, the mixed dry pepper oil material is directly squeezed without being limited by the geographical position of the pepper production area, the application range of the raw materials is , the transportation and storage cost of the dry pepper is lower compared with the wet pepper, the pepper oil can be squeezed at any time according to the market requirement, the fund occupancy rate can be reduced, the process does not need expensive equipment, the labor protection measure is not high, the labor intensity is low, the cost is favorably reduced, the time and the labor are saved, the taste is pure, the pepper fruits are directly squeezed at low temperature through physical machinery, the effective components in the pepper are fully dissolved into the edible vegetable oil, the pepper oil with high effective components is directly obtained, and the original taste and the original flavor and the original nutrients of the pepper are reserved to the maximum extent.
