Embodiment 1

[0018] A kind of rapeseed oil processing method that present embodiment provides, comprises the steps:

[0019] (1) Raw material preparation: take rapeseed and sesame with a mass ratio of 0.01 to the rapeseed, select the high-quality rapeseed oil that is naturally dried to a water content of about 5% for the rapeseed, mix the rapeseed and sesame, and Sesame can increase the aroma of rapeseed oil;

[0020] (2) Dry virgin: add rapeseed and sesame to an oven for drying at 100°C for 40 minutes. Drying can further remove moisture from rapeseed and sesame, and stimulate rapeseed and The aroma of sesame seeds, dried rapeseed and sesame seeds are directly pressed to obtain crude oil;

[0021] (3) Degumming: Add phosphoric acid, carbonic acid and appropriate amount of water to the crude oil and heat and stir at the same time. The degumming time is 30 minutes. The crude oil after degumming is filtered to obtain supernatant oil. The ratio of phosphoric acid and carbonic acid is 3:1, and...

[0026] A kind of rapeseed oil processing method that present embodiment provides, comprises the steps:

[0027] (1) Raw material preparation: take rapeseed and sesame with a mass ratio of 0.01 to the rapeseed, select the high-quality rapeseed oil that is naturally dried to a water content of about 5% for the rapeseed, mix the rapeseed and sesame, and Sesame can increase the aroma of rapeseed oil;

[0028] (2) Dry virgin: add rapeseed and sesame to an oven for drying at a temperature of 120°C for 30 minutes. Drying can further remove moisture from rapeseed and sesame, and stimulate rapeseed and The aroma of sesame seeds, dried rapeseed and sesame seeds are directly pressed to obtain crude oil;

[0029] (3) Degumming: Add phosphoric acid, carbonic acid and appropriate amount of water to the crude oil and heat and stir at the same time. The degumming time is 40 minutes. The crude oil after degumming is filtered to obtain the supernatant oil. The ratio of phosphoric acid and carb...

Embodiment 3

[0034] A kind of rapeseed oil processing method that present embodiment provides, comprises the steps:

[0035] (1) Raw material preparation: take rapeseed and sesame with a mass ratio of 0.01 to the rapeseed, select the high-quality rapeseed oil that is naturally dried to a water content of about 5% for the rapeseed, mix the rapeseed and sesame, and Sesame can increase the aroma of rapeseed oil;

[0036] (2) Dry virgin: add rapeseed and sesame to an oven for drying at 110°C for 35 minutes. Drying can further remove the moisture in rapeseed and sesame, and stimulate the The aroma of sesame seeds, dried rapeseed and sesame seeds are directly pressed to obtain crude oil;

[0037] (3) Degumming: Add phosphoric acid, carbonic acid and appropriate amount of water to the crude oil and heat and stir at the same time. The degumming time is 35 minutes. The crude oil after degumming is filtered to obtain supernatant oil. The ratio of phosphoric acid and carbonic acid is 3:1, and the ra...

Abstract

The invention discloses a rapeseed oil processing method which comprises the following steps: (1) preparing raw materials, namely fully mixing rapeseeds and sesame seeds; (2) drying and primary squeezing: adding the rapeseeds and the sesame seeds into a drying oven for drying, and performing primary squeezing after drying to obtain crude oil; (3) degumming: adding phosphoric acid, carbonic acid and a proper amount of water into the crude oil, heating and stirring at the same time, and filtering the degummed crude oil to obtain supernatant oil; (4) deacidification: adding alkali liquor into thesupernatant oil, heating, stirring, washing with soft water, and carrying out vacuum drying to obtain deacidified oil; (5) decoloring: putting activated clay into the deacidified oil, heating and stirring, and filtering to obtain rapeseed oil, wherein the heating and stirring means that the temperature is 50-70 DEG C. Degumming-deacidifying-decoloring treatment is added in the processing processso that impurities in the prepared rapeseed oil are few, and the rapeseed oil is not easy to oxidize; the rapeseed oil is degummed, decolorized and deacidified at a relatively low temperature so thatbeneficial substances in the rapeseed oil can be completely reserved, and the nutritional value of the rapeseed oil is improved.

Description

technical field [0001] The invention relates to the field of rapeseed oil processing, in particular to a method for processing rapeseed oil. Background technique [0002] Rapeseed oil is commonly known as rapeseed oil, also known as rapeseed oil. It is sweet, pungent, and warm in nature. It can moisten dryness and kill insects, disperse fire pills, and reduce swelling and poison. The human body has a high absorption rate of rapeseed oil, which can reach 99%. Since the raw material for oil extraction is the seed of a plant, it generally contains a certain amount of seed phospholipids, which is very important for the development of blood vessels, nerves, and brain. Rapeseed oil contains little or no cholesterol, so people who control their cholesterol intake can eat it with confidence. High-quality rapeseed oil is a pure natural, pollution-free and healthy edible oil with high grade and high nutritional value. It has the reputation of "Oriental olive oil". It has a mellow s...
