Description

Soybean oil was known to man 6,000 years ago. The technology for its production was first mastered in ancient China, and even then people were well aware of the beneficial properties of soybeans. In China, soybeans were considered a sacred plant, and after a while it began to be cultivated in Korea, and then on the Japanese islands.

In Europe, soy gained popularity in soy sauce, which was imported from Japan, where it was called “se: yu”, which means “soy sauce”. Due to its unique characteristics, soybean oil is currently one of the most popular in countries such as the United States, China and others.

The raw material for it is an annual herb (lat. Glycine max), which is cultivated in more than 60 countries around the world. It is one of the most abundant oilseeds and legumes and is used as raw material for a wide range of food foods.

The popularity of soybeans is due to the high percentage of proteins and nutrients, which allows it to be used as an inexpensive and complete substitute for meat and dairy foods.

Cold-pressed soybean oil has a bright yellow-straw color, a rather specific aroma. After refining, it becomes transparent, with a barely noticeable pink tint.

Soybean oil production technology

As a raw material, only well-cleaned, without signs of fungal infection, mature, sized beans are used. One of the important biochemical indicators in the selection of seeds is the change in the acid number of the kernel oil.

Its growth above 2 mg KOH leads to a decrease in the concentration of crude protein. Another important indicator is the moisture content of seeds, which should not exceed 10-13 percent, which reduces the risk of reproduction of pathogenic microflora, guarantees the safety of the protein component.

The presence of impurities is allowed – no more than 2 percent, as well as destroyed seeds – no more than 10 percent.

Two methods are used to separate oil from seeds:

  • extraction (chemical);
  • pressing (mechanical).

The mechanical method of oil extraction has some advantages, allowing you to fully preserve the natural properties of the product, ensure its environmental friendliness and safety. In most European countries, oil obtained by chemical extraction is not used to produce margarine or salad oil.

The most common mechanical method is single hot pressing, which yields up to 85 percent of an oil with a pleasant smell and intense color. Hot pressing followed by re-pressing can also be used to obtain up to 92 percent oil.

The most common extraction method is pre-pressing, which involves the partial separation of the oil prior to chemical extraction. The cake obtained in this way is crushed and sent to crushing, after which it is subjected to extraction, which is carried out using organic solvents.

To keep the oil longer and not go rancid, it is purified and refined.
