Sunflower oil

Definition

Sunflower oil is the non-volatile oil pressed from the seeds of sunflower (Helianthus annuus). Sunflower oil is commonly used in food as a frying oil, and in cosmetic formulations as an emollient. The world’s total production of sunflower oil in 2014 was nearly 16 million tonnes, with Ukraine and Russia as the largest producers.
Sunflower oil is a mixture, mainly of polyunsaturated fat, linoleic acid (59% of total), monounsaturated fat, and oleic acid (30% of total). In sunflower oil plant breeding and manufacturing, four types of processed oil containing different amounts of the major fatty acids are produced. The expressed oil has a light amber color with a mild flavor. The oil contains a rich content of vitamin E.
As of 2017, genome analysis and the development of hybrid sunflowers to increase oil production are under development to meet greater consumer demand for sunflower oil and its commercial varieties.

Technology

Sunflower Oil Processing Steps
The processing characteristics of first-grade sunflower oil are: first of all, sunflower seeds are selected and cleaned to remove impurities, and then the seeds are de-husked and crushed. After that, the embryo is flaked and steamed in the frying pan, the fried product is pre-squeezed out of the oil and the remaining oil is extracted by solvent leaching. Then, the crude oil is purified through precipitation and filtration. Finally, it is dissolved, degummed, decolorized, deacidified and deodorized into the refined oil.

More specifically, the operation steps and equipment for processing sunflower oil are as follows:
1.Sunflower seeds selection
2. Shelling & Crushing
3.Sunflower Seed Flaking
4.Seed Embryo Steaming
5.Pre-squeezing & Leaching
6. Crude Oil Refining

Uses

In food preparation

Refined sunflower oil is used for low-to-extremely-high-temperature cooking. As a frying oil, it behaves as a typical vegetable triglyceride. Unrefined sunflower oil is a traditional salad dressing in Eastern European cuisines. Sunflower oil is also an ingredient in sunflower butter.

Methods for cooking snack foods such as potato chips or French fries may use sunflower oil.

Seed meal

Extraction of sunflower oil leaves behind the crushed seeds, typically referred to as seed meal, which is rich in protein and dietary fiber. It is used as an animal feed, fertilizer, or fuel.

Supplements

Taking sunflower oil dietary supplements is not an effective treatment for eczema.

As fuel

Sunflower oil can be used to run diesel engines when it is mixed with diesel in the tank. Due to the high levels of unsaturated fats, there is higher viscosity in cold temperatures.
