Method for preparing oil from high-quality rapeseeds with high content of oil under low-temperature and low-moisture conditions

Abstract

The invention discloses a method for preparing oil from high-quality rapeseeds with high content of oil under low-temperature and low-moisture conditions. The method comprises the following steps: selecting raw materials, cleaning and carefully choosing the raw materials, drying and conditioning at a low temperature, conditioning, peeling the rapeseeds, separating peels from kernels, conditioning at a low temperature, squeezing at a low temperature and carrying out pure physical filtration and fine filtration. High-quality natural high-grade and high-end oil is obtained from the high-quality rapeseeds with high content of oil under low-temperature and low-moisture pure physical process technical conditions, compared with commercially available leaching oil and hot-pressed oil, the rapeseed oil is natural, clear and transparent, has golden color and is rich in natural vitamin E and phytosterols; the content of protein in the cakes is increased and the biological activity of protein in rapeseed meals is ensured; the method has the advantages of low energy consumption, low cost and no pollutants.

Description

technical field

[0001] The invention relates to the technical field of rapeseed oil extraction, in particular to a method for producing oil from high-quality rapeseed with high oil content under low-temperature and low-moisture conditions. Background technique

[0002] With the improvement of living standards, people's demand for edible vegetable oil is increasing year by year. In recent years, the amount of imported oil and oilseeds in my country has increased from 4.614 million tons in 2000 to 20.889 million tons in 2010, an increase of 535% in ten years, with an average annual growth rate of 35.3%. The self-sufficiency rate of edible vegetable oil has dropped from 60% at the beginning of this century to about 37% at present. The self-sufficiency rate of edible vegetable oil is quite lacking, especially the demand for high-end edible vegetable oil is quite scarce, and there is an urgent need to develop and produce high-end edible vegetable oil suitable for the lives of ou...
