sunflower soybean oil refining process

Sunflower soybean oil refining methods can be roughly divided into the mechanical method, chemical method, and physicochemical method. The operation of the sunflower soybean oil refining machine is divided into the following four steps.

1. Degumming: if the content of phospholipids in the sunflower seed oil is high, it is easy to blister, produce smoke, and smell when heated. The phospholipids oxidized at high temperature turns the oil scorch brown, which affects the flavor of fried food. Degumming is based on the principle that phospholipids and some proteins are insoluble in oil after forming hydrate with water. By adding hot water to the crude sunflower seed oil, mixing and heating at 50℃, the phospholipids and some proteins can be removed after static stratification.

2. Deacidification: free fatty acids affect the stability and flavor of sunflower seed oil. They can be removed by neutralization with alkali solution.

3. Decolorization: crude sunflower seed oil contains pigments such as chlorophyll and carotenoids. Chlorophyll is a photosensitizer, which affects the stability of the oil, while other pigments affect the appearance of oil, which can be removed by the adsorbent.

4. Deodorization: there are some peculiar smell substances in crude sunflower seed oil, mainly from oil oxidation products. Such gases can be removed by distillation and vacuum pumping.

5. Dewaxing: remove the wax in the sunflower seed oil.

The first-grade and second-grade sunflower soybean oil generally need to go through 5 procedures: degumming, deacidification, decolorization, deodorization, or dewaxing, while the third and fourth-grade oil does not need to go through deodorization and dewaxing.

South Africa Soybean Oil Industry

South Africa's consumption of soybean oil is due to reach almost 300,000 metric tons in 2026, a slight 1% increase from 2021. For the past four years, demand has grown at a rate of 1.4% annually. In 2021, Italy was the largest consumer at 279,000 metric tons, while South Africa ranked 17th. China, India and Brazil followed in the ranks. Meanwhile, South African production of soybean oil is expected to climb 3.3% year on year to reach 252,000 metric tons by 2026. Since 1966, output has increased by almost 5% annually. Bangladesh was in the lead in 2021 with 207,000 metric tons, followed by the United States, Brazil and Argentina.
