preparation example Construction

[0021] like figure 1 Shown, the invention provides a kind of strong fragrant rapeseed oil preparation method, comprises the steps:

[0022] Step 1. The rapeseed with a moisture content of 14-18% is sequentially subjected to impurity removal, water washing, and tempering treatment to obtain rapeseed raw materials with a moisture content of 6-8%, and the rapeseed raw materials are divided into pressed rapeseed Raw material and back-pressed rapeseed raw material, the mass ratio of said pressed rapeseed raw material to said back-pressed rapeseed raw material is 3:1.

[0023] Step 2: Squeeze the pressed rapeseed raw material, first heat the pressed rapeseed raw material to 105-110°C, press for 10-20 minutes, continue heating to 110-115°C, and keep pressing for 20-20°C After 40 minutes, press rapeseed crude oil and press cake are obtained, and the oil content of the press cake is 8-10%.

[0024] Step 3, crushing the pressed cake and mixing it with the returned rapeseed raw materia...

Embodiment 1

[0028] The rapeseed with a moisture content of 16% is sequentially removed from impurities, washed with water, and tempered to obtain a rapeseed raw material with a moisture content of 7%, and the rapeseed raw material is divided into a pressed rapeseed raw material and a back-pressed rapeseed raw material Carry out pressing treatment to described pressed rapeseed raw material, first described pressed rapeseed raw material is heated to 108 ℃, presses 15 minutes, continues heating to 112 ℃, and keeps pressing 30 minutes, obtains pressed rapeseed crude oil and Pressed cake, the oil content of the pressed cake is 9%; the pressed cake is crushed and mixed with the repressed rapeseed raw material to obtain a mixed rapeseed raw material, and the mixed rapeseed raw material is steamed and fried , the steaming and frying process is as follows: crush the pressed cake and mix it with the repressed rapeseed raw material to obtain the mixed rapeseed raw material. In the first stage, the mi...

Embodiment 2

[0030]The rapeseed with a moisture content of 14% is sequentially removed from impurities, washed with water, and tempered to obtain a rapeseed raw material with a moisture content of 6%, and the rapeseed raw material is divided into a pressed rapeseed raw material and a back-pressed rapeseed raw material Carry out pressing treatment to described pressed rapeseed raw material, first described pressed rapeseed raw material is heated to 105 ℃, presses 10 minutes, continues heating to 110 ℃, and keeps pressing 20 minutes, obtains pressed rapeseed crude oil and Pressed cake, the oil content of the pressed cake is 8%; the pressed cake is crushed and mixed with the repressed rapeseed raw material to obtain a mixed rapeseed raw material, and the mixed rapeseed raw material is steamed and fried , the steaming and frying process is as follows: crush the pressed cake and mix it with the repressed rapeseed raw material to obtain the mixed rapeseed raw material. In the first stage, the mix...

Abstract

The invention discloses a method for preparing strong-flavored rapeseed oil, which comprises the following steps: preparing rapeseed raw material, and dividing the rapeseed raw material into pressed rapeseed raw material and back-pressed rapeseed raw material; Pressing the raw materials to obtain pressed rapeseed crude oil and pressed cakes; crushing the pressed cakes and mixing them with the repressed rapeseed raw materials to obtain mixed rapeseed raw materials, and steaming and frying the mixed rapeseed raw materials , to obtain steamed and fried rapeseed raw materials; the steamed and fried rapeseed raw materials are subjected to back-pressing treatment to obtain back-pressed rapeseed crude oil; the pressed pressed rapeseed crude oil and back-pressed rapeseed crude oil are mixed to obtain vegetable crude seed oil, and carry out hydration treatment to the rapeseed crude oil to be refined to obtain the finished product Luzhou-flavored rapeseed oil. The preparation method of the fragrant rapeseed oil provided by the invention has a simple process, is safe and reliable, and the fragrance substances in the prepared rapeseed oil will not be lost due to over-refining, and the fragrance is stronger and more lasting.

Description

technical field [0001] The invention relates to the technical field of oil processing methods, in particular to a preparation method of fragrant rapeseed oil. Background technique [0002] Rapeseed oil, referred to as "vegetable oil" for short, is one of the main oil crops in my country. It is mainly obtained from the seeds of Brassica cruciferae (rape), and its main production areas are in the Yangtze River Basin, Southwest and Northwest China. Rapeseed oil is golden or brown in color and has a certain pungent smell, which is generally called "green smell". Rapeseed oil has a certain effect of softening blood vessels and delaying aging. It contains little or almost no cholesterol, so people who control cholesterol intake can eat it with confidence. The existing rapeseed oil production process is generally a pre-pressing-extraction process, and the obtained rapeseed oil has insufficient fragrance. With the improvement of people's living standards, the demand for strong frag...
