Embodiment 1

[0020] A preparation method of tertiary double-low rapeseed oil includes the following steps:

[0021] (1) Cleaning: First use a windmill to remove the ash lighter than the rapeseed, and then use a coarse and fine sieve to remove the impurities larger than and smaller than the rapeseed, then put the rapeseed in the water, lightly by hand Knead gently for 5 minutes to remove the sludge covering the surface of the rapeseed, and then remove the rapeseed;

[0022] (2) Stir-fry seeds: put the picked rapeseed into a jacketed pot, control the initial frying temperature to 150°C for 20 minutes, then adjust the temperature to 100°C, and after 15 minutes of frying, adjust the temperature to 80°C and stir-fry When the moisture content of the rapeseed is 8%, it can be out of the pot;

[0023] (3) The rapeseed treated in step (2) is repeatedly squeezed twice with a double-screw low-temperature oil press. During oil pressing, the temperature in the press chamber is controlled to 100°C and the oil...

[0039] A preparation method of tertiary double-low rapeseed oil includes the following steps:

[0040] (1) Cleaning: First use a windmill to remove the ash lighter than the rapeseed, and then use a coarse and fine sieve to remove the impurities larger than and smaller than the rapeseed, then put the rapeseed in the water, lightly by hand Knead gently for 6 minutes to remove the sludge covering the surface of the rapeseed, and then remove the rapeseed;

[0041] (2) Fried seeds: put the picked rapeseeds into a jacketed pot, control the initial frying temperature to 180°C for 25 minutes, then adjust the temperature to 110°C, after 20 minutes of frying, adjust the temperature to 90°C, and stir-fry When the moisture content of rapeseed reaches 10%, it can be out of the pot;

[0042] (3) The rapeseed treated in step (2) is repeatedly squeezed 3 times with a double-screw low-temperature oil press. During oil pressing, the temperature in the press chamber is controlled to 110°C and the oil ...

Abstract

The invention discloses a preparation method of third-order double-low rapeseed oil, which belongs to the technical field of oil processing. The preparation method comprises the following steps: cleaning rapeseeds, placing the cleaned rapeseeds into a sandwiched pot, stir frying the rapeseeds until the water content of the rapeseeds is 8 to 12 percent, and then taking the rapeseeds out of the pot;repeatedly squeezing the rapeseeds by adopting a dual-screw low-temperature oil squeezing machine to obtain crude rapeseed oil; adding non-iodine saline solution into the crude oil, and hydrating; sending the hydrated oil into an oil refining pot to be treated, and filtering to obtain filtrate; heating the filtrate to 300 to 500 DEG C, treating the filtrate for 5 to 10 min, and obtaining concentrated fragrance base oil; and mixing the concentrated fragrance base oil and first-order rapeseed oil after being refined, thus obtaining third-order double-low rapeseed oil. By adopting the preparation method disclosed by the invention, the content of erucic acid in the rapeseed oil and the content of glucosinolate in a rapeseed cake can be significantly reduced, so that the edible rapeseed oil ishealthier.

Description

Technical field [0001] The invention relates to the technical field of edible oil processing, in particular to a preparation method of three-grade double-low rapeseed oil. Background technique [0002] Rapeseed oil, commonly known as rapeseed oil, is also called rapeseed oil. It is sweet, pungent, and warm in nature. The human body's absorption rate of rapeseed oil is very high, up to 99%. Therefore, it contains unsaturated fatty acids such as linoleic acid and nutrients such as vitamin E can be well absorbed by the body, and has a certain effect of softening blood vessels and delaying aging. Since the raw material for oil extraction is plant seeds, it generally contains certain seed phospholipids, which are very important for the development of blood vessels, nerves, and brain. Canola oil contains little or no cholesterol, so people who control their cholesterol intake can eat it with confidence. [0003] The commonly used rapeseed oil processing technology is as follows: (1) C...
