Embodiment 1

[0022] A processing method of high-quality soybean oil, comprising the following steps:

[0023] (1) Soybean pretreatment: Soybeans are air-selected, dried and pulverized successively to obtain soybean powder; said air-selection is to add soybeans to a suction flat sieve to remove impurities such as metals, stones and dust in soybeans; The drying is to send the air-selected soybeans into a dryer, and dry them at a temperature of 40°C until the moisture content is 5%; the crushing is to send the dried soybeans into a grinder and grind them to a fineness of 20 head;

[0024] (2) Soybean pressing oil production: mix soybean powder, Kudingcha dry tea and camellia seeds and send them into a double-screw low-temperature oil press, press at a temperature of 40°C to obtain pressed oil; The weight ratio of Dingcha dry tea and camellia seeds is 100:0.5:5; the fineness of the camellia seeds is 60 mesh;

[0025] (3) Refined soybean oil: After the squeezed oil is filtered with an 80kD ul...

Embodiment 2

[0027] A processing method of high-quality soybean oil, comprising the following steps:

[0028] (1) Soybean pretreatment: Soybeans are air-selected, dried and pulverized successively to obtain soybean powder; said air-selection is to add soybeans to a suction flat sieve to remove impurities such as metals, stones and dust in soybeans; The drying is to send the air-selected soybeans into a dryer, and dry them at a temperature of 60°C until the moisture content is 7%; the crushing is to send the dried soybeans into a grinder and grind them to a fineness of 30 head;

[0029] (2) Soybean press oil production: mix soybean powder, Kudingcha dry tea and camellia seeds and send them into a double-screw low-temperature oil press, press at a temperature of 60°C to obtain pressed oil; The weight ratio of Dingcha dry tea to camellia seeds is 100:1:8; the fineness of the camellia seeds is 100 mesh;

[0030] (3) Refined soybean oil: After the pressed oil is filtered with a 120kD ultra-mi...

Abstract

The invention discloses a processing method for high-quality soybean oil. The processing method comprises the following steps: firstly, sequentially winnowing, drying and crushing soybeans; mixing and squeezing the obtained soybean powder and dry broadleaf holly leaves and camellia seeds; then carrying out ultrafine filtration, hydration and degumming, light treatment and steaming deodorization on the obtained squeezed oil; and then removing free fatty acids to obtain a soybean oil finished product. The soybean oil disclosed by the invention is relatively pure and abundant in nutrient and has a slight tea fragrance.

Description

technical field [0001] The invention relates to the technical field of vegetable oil preparation, in particular to a method for processing high-quality soybean oil. Background technique [0002] Soybean oil is a kind of oil extracted from soybean seeds. Soybean oil is light yellow, clear and transparent, and has no sediment. Good quality soybean oil is lighter in color. The fatty acid composition of soybean oil is better. It is rich in linoleic acid, which is an essential fatty acid for human body and has important physiological functions. Linoleic acid has a significant effect on preventing cardiovascular diseases, and can reduce serum cholesterol levels. Soybean oil contains a lot of vitamin E, vitamin D and rich lecithin, which are very beneficial to human health. The lack of linoleic acid in young children will not only cause dry skin and thickened scales, but also slow growth and development; the lack of linoleic acid in the elderly will cause cataracts and cardiovascu...
