specific Embodiment 1

[0018] Step 1. Dry the pepper seeds, cool the pepper seeds to 30 degrees Celsius in the form of blowing cold air, and reduce the water content of the pepper seeds to 6%.

[0019] Using the low-temperature dehydration method, compared with the previous hot air drying method, the linoleic acid and linolenic acid in the pepper seed oil can be kept to the maximum extent, and will not decompose at high temperature and lose with water.

[0020] Step 2. Peeling the pepper seeds to reduce the mass percentage of the pepper seeds in the pepper seeds to below 10%.

[0021] If the seed skin of Zanthoxylum bungeanum is not removed, in the subsequent pressing process, the skin will produce substances that destroy the unsaturated fatty acid components in the Zanthoxylum bungeanum oil, and at the same time affect the aroma and purity of the final finished Zanthoxylum bungeanum oil, so it should be as possible Remove pepper seed skin.

[0025] Step 1. Dry the pepper seeds, cool the pepper seeds to 30 degrees Celsius in the form of blowing cold air, and reduce the water content of the pepper seeds to 10%.

[0026] The step 1 also includes a step of removing iron and sand, using a sieve larger than 200 mesh to filter the sand contained in the pepper seeds, and electromagnets can also be used to absorb the iron sand contained in the pepper seeds to remove these impurities with high hardness and avoid Abrasion of the anti-corrosion coating on contact surfaces that destroy machinery and equipment during subsequent pressing.

[0027] Step 2. Peeling the pepper seeds, so that the mass percentage of the pepper seeds in the pepper seeds is reduced to below 7%.

[0028] Step 3. Press the peeled pepper seeds to obtain crude oil. After sedimentation and filtration, the crude oil is sent to a hydration tank for hydration treatment. After hydration is completed, dehydration and drying are carried out.

[0029] Step 1. Dry the pepper seeds, cool the pepper seeds to 20 degrees Celsius in the form of blowing cold air, and reduce the water content of the pepper seeds to 6%.

[0030] The step 1 also includes a step of removing iron and sand, using a sieve larger than 200 mesh to filter the sand contained in the pepper seeds, and electromagnets can also be used to absorb the iron sand contained in the pepper seeds to remove these impurities with high hardness and avoid Abrasion of the anti-corrosion coating on contact surfaces that destroy machinery and equipment during subsequent pressing.

[0031] Step 2. Peeling the pepper seeds, so that the mass percentage of the pepper seeds in the pepper seeds is reduced to below 7%. During the peeling process in step 2, the temperature is not higher than 30 degrees Celsius, and the peeling operation is performed at a low temperature, so that the linoleic acid and linolenic acid in the pepper seed oil can be kept to the maximum, and will not ...

Abstract

The invention discloses a method for preparing prickly ash seed oil through mechanical compression. The method comprises the following steps: step 1, drying prickly ash seeds, that is, blowing cold wind to cool the prickly ash seeds to 15-40 DEG C and to lower the water content of the prickly ash seeds to 4-10%; step 2, conducting peeling treatment on the dried prickly ash seeds, so as to lower the mass percent of prickly ash seed peels in the dried prickly ash seeds to 10% or below; step 3, compressing the peeled prickly ash seeds to obtain crude oil, conducting settlement and filtration on the obtained crude oil, and feeding the treated crude oil into a hydration tank for hydration treatment, and carrying out dehydration and drying after the hydration treatment. Through adoption of the peeling and cold compression processes, the method is simple and under a low-temperature condition, most natural and active nutrients can be kept in a finished prickly ash seed oil product during compression; due to the mechanical compression process, the introduction of chemical constituent is avoided, and both the prickly ash seed oil and the method provided by the invention are more environmental-friendly.

Description

technical field [0001] The invention belongs to the field of plant processing, and relates to a method for processing vegetable oil, in particular to a method for mechanically pressing Zanthoxylum bungeanum seed oil. Background technique [0002] Zanthoxylum bungeanum is a special seasoning raw material in my country. Due to the increase in export volume, the planting area has soared. After investigation, it is estimated that there are about 100,000 tons of pepper seeds in the country to be processed and utilized. [0003] The oil content in Zanthoxylum bungeanum is 27% to 31%. Among its fatty acid components, more than 90% are unsaturated fatty acids, and the content of essential fatty acids (linoleic acid, linolenic acid) that cannot be synthesized by the human body is more than 45%. Therefore, Zanthoxylum bungeanum oil is an ideal edible vegetable oil, and the protein content of Zanthoxylum bungeanum also accounts for 18.7%, and the amino acid composition is relatively r...
