Problems solved by technology

[0005] According to the analysis of the above two Chinese patent documents combined with the existing rapeseed oil and its preparation method, in the preparation process of the existing rapeseed oil, the general refining technology is generally used, which generally has a serious over-processing problem , so that the amount of raw and auxiliary materials for rapeseed oil refining increases, the consumption of oil refining and energy consumption increases, the discharge of processing wastewater and waste residues exceeds the standard, the environment is damaged, and the original nutrients in rapeseed oil are also over-processed and removed. It has caused a decline in the nutritional quality of rapeseed oil. At the same time, excessive processing has also increased the content of harmful oil companions such as trans fatty acids in the oil, which has reduced the edible safety of the oil. Moreover, the antioxidant capacity of rapeseed oil is not high enough, and it cannot Strengthen blood vessels, therefore, those skilled in the art provide a kind of rapeseed oil and its preparation method, to solve the problems raised in the background technology above

Embodiment 1

[0035] A kind of rapeseed oil and preparation method thereof, comprises the following steps:

[0036] Step 1), pretreatment: first use the fan to remove the dust and impurities in the rapeseed, and then use a sieve to sieve, so as to facilitate the screening of the fine impurities in the rapeseed, and put the screened rapeseed into After soaking in water for 3 minutes, gently rub the rapeseed with your hands for 3 minutes to remove the dirt on the surface of the rapeseed, then fish it out and dry it in the air;

[0037] Step 2), stir-fry: put the clean rapeseed obtained in step 1) into the sandwich pot for stir-fry, the initial temperature is controlled at 150°C, the time is 30min, the mid-term temperature is lowered to 100°C, and stir-fry again for 15min, In the later stage, the temperature is controlled at 70°C for 10 minutes, and then the water content of the rapeseed is fried to a range of 7%, and then it can be taken out of the pot;

[0038] Step 3), grinding: Put the ra...

Abstract

The invention discloses a rap oil and a preparation method thereof. The rap oil comprises the following steps of 1) pretreatment, 2) stir-frying, 3) grinding, 4) deacidification treatment and 5) mixing. Through deacidification treatment on the rap oil and by adding in filtering aids for filtering and saponin removal, saponin can be removed via filtering, and meanwhile a small quantity of colloid impurities removed during a colloid-removing process can be further filtered, so that the sensory quality of the rap oil can be greatly improved; anti-hypertensive mixed liquor is added during preparation of the rap oil, so that the prepared rap oil can be light in taste, rich in original flavor and highly accepted by intestines and stomach; meanwhile, the rap oil can achieve excellent oxidation resistance, prolong the storage duration and retard oxidation, and meanwhile, can strengthen blood vessels, avoid vasoconstriction and abrupt blood pressure elevation to achieve great beneficial effectson human body; during long-term use, the rap oil can inhibit blood pressure elevation and promote body metabolism.

Description

technical field [0001] The invention relates to the technical field of rapeseed oil production, in particular to a rapeseed oil and a preparation method thereof. Background technique [0002] In my country, residents in northwest and central China generally like to eat rapeseed oil. Studies have shown that among vegetable oils, rapeseed oil contains the least saturated fatty acid, only 6%, and unsaturated fatty acid accounts for more than 90%. Therefore, rapeseed oil is beneficial to gallbladder function and lowers cholesterol in the human body. Rapeseed oil is also rich in vitamin E and oleic acid, linoleic acid, linolenic acid and so on. The human body has a high rate of digestion and absorption of rapeseed oil, and the rate of digestion and utilization can reach 99%. Its nutrients can be fully absorbed by the body to promote growth and development, maintain physiological metabolism, reduce cholesterol levels, and prevent diseases. [0003] A Chinese patent discloses a k...
