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

Abstract

The invention discloses a strong-flavor rapeseed oil processing method, which comprises: pounding agastache rugosa, dianthus chinensis l, peppermint, melissaofficinalis l, osmanthus fragrans and camellia japonica l, adding water, decocting, and filtering to obtain an ingredient liquid; selecting high-quality rapeseed, peeling to obtain rapeseed kernel, heating for a certain time with steam, adding edible salt, uniformly mixing, adding to the ingredient liquid, soaking for a certain time, filtering, adjusting the water content of the rapeseed kernel, carrying out a microwave pretreatment, cooling, and carrying out cold pressing to obtain pressed oil and pressed cake; and carrying out degumming, alkali refining, decoloring and deodorizing on the pressed oil to obtain the strong-flavor rapeseed oil. According to the present invention, the strong-flavor rapeseed oil processing method is provided, wherein the low temperature cold pressing is used, the oil yield is high, the prepared strong-flavor rapeseed oil has advantages of rich flavor, high nutritional value, good oxidation stability and no pollution, the pure nature property of the rapeseed oil is ensured, and the requirements of green food are met.

Description

technical field [0001] The invention relates to the technical field of edible oils, in particular to a processing method of fragrant 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 oil and reduce the ...
