Problems solved by technology

[0003] Most of the commonly used sunflower oil extraction processes are cold pressing. Compared with hot pressing and other innovative methods, cold pressing has good physical and chemical indicators and meets edible oil standards on the basis of ensuring environmental protection and saving. , but the conventional cold pressing method also has many problems, such as the high content of phenolic acid in the oil, which causes the sunflower oil to be easily oxidized and discolored, which affects the protein function; the cold pressed sunflower seed crude oil contains more gums, and the oil quality is not high, etc.

Embodiment Construction

[0030] A new sunflower seed oil extraction method requires the sunflower seeds to be shelled and impurities removed in the early stage, and then the specific steps are as follows:

[0031] Step 1: Dephenolization by segmental water division. Studies have shown that the main component of phenolic acids contained in sunflower seeds is chlorogenic acid. Chlorogenic acid and protein will be oxidized in a slightly alkaline environment to form indigestible, indigestible The absorbed quinones will also produce a deeper color, which makes the finished sunflower oil look bad;

[0032] Chlorogenic acid is a small molecular component. According to the principle of diffusion, when sunflower seeds are placed in water, chlorogenic acid, some carbohydrates, and non-proteins will be discharged out of the sunflower seeds through the semipermeable membrane of the sunflower seed cells, while some proteins Such macromolecules will remain in the sunflower kernels. The specific operation of this a...

Abstract

The invention relates to a novel sunflower seed oil squeezing method. The novel sunflower seed oil squeezing method comprises the following steps: step 1, dephenolizing by a segmented water removal method; step 2, drying; step 3, squeezing; step 4, degumming; step 5, deacidifying and decolorizing; step 6, dewaxing; and step 7, deodorizing. The squeezing method breaks through the structural technology limitation of the original technological process, optimizes each working section of the cold squeezing process, and maximizes the overall benefit.

Description

technical field [0001] The invention relates to a novel method for extracting sunflower oil, which belongs to the field of vegetable oil production and processing. Background technique [0002] Sunflower oil is a high-grade edible oil with a pure texture and a light nutty taste. Sunflower oil is rich in various vitamins, unsaturated fatty acids, sterols and linoleic acid, and many other substances beneficial to human beings. Among them, the natural vitamin E content is much higher than other vegetable oils such as peanut oil and sesame oil, which can achieve the effect of delaying the aging of cells. The content of linoleic acid is as high as 70%, which can regulate the metabolism of the human body, maintain the balance of blood pressure, effectively reduce the level of cholesterol in the serum, and prevent cardiovascular diseases such as arteriosclerosis and coronary heart disease. In sunflower oil, the content of vitamins and linoleic acid is very balanced, which can mak...
