Embodiment 1

[0027]The processing method of fragrant rapeseed oil comprises the steps:

[0028] (1) Soaking: Soak the de-impured rapeseed in water at a temperature of 40°C for 1 hour, so that the rapeseed absorbs water and is in a relatively saturated state;

[0029] (2) Microwave treatment: Air-dry the rapeseed treated in step (1) until there is no obvious moisture on the surface, then treat it with microwave for 5 minutes, and the microwave power is 800w, so that the moisture content of the rapeseed is reduced to 3-4%;

[0030] (3) Initial peeling and separation of skin and kernel: Send the rapeseed treated in step (2) into the automatic peeling equipment, and remove the rapeseed skin by rubbing. For skin, the kneading time is designed to be 30 minutes, and then the skin and kernel are separated by winnowing;

[0031] (4) Stir-fried seeds: Put the rapeseed treated in step (3) into a special direct-fire frying pan, first stir-fry on low heat for 3-5 minutes, then change to high heat and ...

Embodiment 2

[0037] The processing method of fragrant rapeseed oil comprises the steps:

[0038] (1) Soaking: Soak the de-impured rapeseeds in water at a temperature of 35°C for 2 hours, so that the rapeseeds absorb water in a relatively saturated state;

[0039] (2) Microwave treatment: Air-dry the rapeseed treated in step (1) until there is no obvious moisture on the surface, then treat it with microwave for 8 minutes, and the microwave power is 600w, so that the moisture content of the rapeseed is reduced to 4-6%;

[0040] (3) Initial peeling and separation of skin and kernel: Send the rapeseed treated in step (2) into the automatic peeling equipment, and remove the rapeseed skin by rubbing. For skin, the kneading time is designed to be 35 minutes, and then the skin and kernel are separated by winnowing;

[0041] (4) Stir-fried seeds: Put the rapeseed treated in step (3) into a special direct-fired frying pan, first stir-fry on low heat for 3-5 minutes, then change to high-fire and sti...

Abstract

The invention discloses a method for processing concentrated coriander seed oil. The method comprises the steps of soaking, microwave treatment, preliminary peeling, separation of skin and kernels, kernel frying, second peeling, low temperature pressing, fine filtration and the like. The method not only improves the peeling rate (96% or more), but also has a low destruction rate of the kernels, does not cause a paste pot phenomenon, and improves the oil yield rate, and in addition, due to a maillard reaction and an oxidation reaction of oil and fat occurring during the frying process in directcontact with a fire source, the formation of small-molecule flavoring substances such as aldehydes, alcohols, heterocyclics and the like makes the coriander seed oil rich in flavors.

Description

technical field [0001] The invention relates to a processing method of fragrant rapeseed oil, which belongs to the technical field of rapeseed processing. Background technique [0002] Rapeseed oil is one of the main edible oils in my country. With the continuous improvement of national living standards, the residents' diet concept has also undergone tremendous changes, from food and clothing to nutrition and health care. Rapeseed oil is in increasing demand. The preparation technology of rapeseed oil is also from pressing with shell to pressing after shelling, and then to today's pressing of fried seeds. The technology of producing strong-flavored rapeseed oil is constantly developing. [0003] The formation of the strong aroma of rapeseed oil is mainly caused by the physical and chemical reaction of the protein, reducing sugar and lipid contained in the oil after the oil is roasted at high temperature. The frying-pressing process is the mainstream process for the preparat...
