Problems solved by technology

[0003] The traditional rapeseed oil production process is divided into two types: mechanical pressing and solvent leaching. The mechanical pressing process uses physical extrusion to squeeze oil out of rapeseed. It is divided into hot pressing and cold pressing. General hot pressing will seriously damage rapeseed cells, and will destroy the nutrients in the oil after high temperature, reducing the nutritional value and quality of rapeseed oil, while the oxidation stability of cold-pressed oil is not very ideal, and the oil yield is low

Embodiment 1

[0015] A method for processing Luzhou-flavor rapeseed oil, comprising the following steps:

[0016] ①Cleaning and flaking: screening, magnetic separation and stone removal of rapeseeds, after cleaning, the impurity index is less than 0.4%, and flaking of rapeseeds;

[0017] ②Fried seeds: Mix rapeseed and Humulus evenly to obtain a mixed material, then cool the temperature of the mixed material to -5°C, and then rapidly raise the temperature to 100°C within 15 minutes, keep it warm for 5 minutes, and then press at a pressure of 2.5MPa, ozone concentration of 55% of the environment for 12 minutes after treatment, then use 250W microwave treatment for 2 minutes, and finally steam and fry, steam and fry for 55 minutes;

[0018] ③Extrusion: After pressing the rapeseed with a pre-extractor, at the same time, the pressed cake is entered into the leaching workshop for leaching, and finally crude oil is obtained;

Abstract

The invention discloses a processing method of strongly-aromatic rapeseed oil. The processing method comprises following steps: (1), cleaning and flaking; (2), seed stir-frying; (3), squeezing; (4), crude oil refining. According to the method, after pressed oil preparation,residual oil of press cakes and residual oil of extraction meal are both in a lower level and reach 8.2% and 0.7% respectively; after the rapeseeds are stir-fried with the method, protein in embryos of the rapeseeds can be denatured sufficiently, vitta in the rapeseed protein is sufficiently opened, plasticity is improved, so that the press cakes and follow-up extraction mealcontain less residual oil, and the pressed oil is lighter in color, has strong rapeseed oil aroma and has specific aroma and smooth taste of the strongly-aromatic rapeseed oil.

Description

technical field [0001] The invention relates to the field of processing agricultural by-products, in particular to a processing method for strong-flavor rapeseed oil. Background technique [0002] Rapeseed oil is one of the traditional edible vegetable oils in my country. It has high nutritional value and is easy to be absorbed by the human body. Its main component is triacylglycerol. Nutrients, these nutrients have a variety of physiological activities and health functions, and their strong antioxidant activity also plays a positive role in protecting the oxidative stability of rapeseed oil. [0003] The traditional rapeseed oil production process is divided into two types: mechanical pressing and solvent leaching. The mechanical pressing process uses physical extrusion to squeeze oil out of rapeseed. It is divided into hot pressing and cold pressing. Ordinary hot pressing will seriously damage the rapeseed cells. After high temperature, it will destroy the nutrients in the...
