Sunflower oil

Sunflower oil comes from small seeds.

People squeeze the seeds to get the oil.

This oil is a liquid at room temperature. It is a great way to cook food. You can use it to fry snacks like chips.

It also has a lot of vitamin E. This oil can even be used in lotions. It is a very useful gift from the sunflower.

Sunflower oil comes from the seeds of the sunflower plant.

People can get the oil in two ways. They can crush the seeds to squeeze it out. This is called expeller pressing. They can also use chemicals to pull the oil out.

This oil is a liquid at room temperature. It has a very neutral taste. This makes it great for cooking. You can use it to fry foods like potato chips. Some oils are refined to help them stay stable at high heat. Refined oil is clear and pale yellow.

Other oils are unrefined. These keep more of their natural color and flavor. They look light amber.

Sunflower oil is full of nutrients. It is a rich source of vitamin E. It is also made of fats called oleic acid and linoleic acid. People make different kinds of oil by changing these fats. Some oils have more of one fat than the other. This helps people use the oil in different ways. It can even be used in some cosmetics. It can also be used as fuel for diesel engines.

Sunflower oil is a liquid made from the seeds of the sunflower plant.

People use this oil in many ways every day. It is a common ingredient for frying food in the kitchen. It can also be used in cosmetics to help skin. The oil has a very neutral taste. This means it does not change the flavor of your food. It is also a rich source of vitamin E.

There are two main ways to get the oil from the seeds. One way is called expeller pressing. This happens when seeds are crushed to squeeze the oil out. This can be done as cold-pressing at low temperatures. Another way uses chemical solvents to pull the oil out. This second way is often used for refining. Refining makes the oil more stable for high heat cooking.

Humans have used sunflowers for a very long time. Native Americans used oil from the seeds after they domesticated the plant around 3000 BC. In more recent history, people first used sunflower oil in food in Russia. Today, it is a huge part of the world food supply. In 2022, the world produced 20.3 million tonnes of this oil. Russia and Ukraine produced 55% of that total amount.

Scientists can change the oil by changing its fats. The oil is mostly made of oleic acid and linoleic acid. These are types of fats called monounsaturated and polyunsaturated fats. Different kinds of oil are made through plant breeding. For example, high-oleic oil has 82% oleic acid. Conventional high-linoleic oil has 69% linoleic acid. There is also mid-oleic oil with 65% oleic acid. A special type has 18% stearic acid and 72% oleic acid.

Sunflower oil is much more than just a cooking ingredient. The leftover crushed seeds are called seed meal. This meal is used as animal feed or fertilizer. The oil can even be used as fuel for diesel engines. In the European Union, it can be sprayed on tomato crops. This helps control a fungus called powdery mildew. It is even used in some cosmetic products.

Sunflower oil is a non-volatile oil extracted from the seeds of the sunflower plant, known scientifically as *Helianthus annuus*.

This substance is primarily used in food preparation and the cosmetics industry. In kitchens, it serves as a common frying oil due to its neutral taste profile. In beauty products, it acts as an emollient, which is a substance used to soften or soothe the skin. The oil is composed mainly of triglycerides, which are a type of fat.

To obtain the oil, producers use different extraction methods. One method is expeller pressing, where seeds are crushed to squeeze the oil out directly. If this occurs under low-temperature conditions, it is called cold-pressing. Another method involves using chemical solvents, such as hexane, to extract the oil. After extraction, the oil may undergo refining. This process includes steps like de-gumming, neutralization, and bleaching. Refining makes the oil more stable for high-temperature cooking, but it also removes certain nutrients, flavors, and colors.

The chemical makeup of sunflower oil is defined by its fatty acids. It is largely composed of linoleic acid, a polyunsaturated fat, and oleic acid, a monounsaturated fat. Through selective plant breeding and industrial processing, manufacturers create four distinct types of oil. High-linoleic oil, often called conventional, contains 69% linoleic acid. High-oleic oil contains 82% oleic acid. Mid-oleic oil contains 65% oleic acid. There is also a high-stearic variety that contains 18% stearic acid and 72% oleic acid.

Human history with the sunflower is quite ancient. Following the domestication of the sunflower around 3000 BC, Native Americans utilized oil from the seeds. In the modern era, Russia was the first place to use sunflower oil in food. Today, it is a massive global commodity. In 2022, the total world production reached 20.3 million tonnes. Russia and Ukraine were the leaders in this industry. Together, these two countries accounted for 55% of the total global production. However, the Russian invasion of Ukraine in 2022 caused global prices to rise by as much as 58% in a single month.

Because of its chemical structure, sunflower oil requires careful storage. The polyunsaturated and monounsaturated fatty acids are less stable than other fats. They are susceptible to degradation caused by heat, air, and light. This process, called oxidation, can lead to rancidity. To prevent nutrient loss and spoilage, producers often store the oil at low temperatures. Using darkly-colored glass bottles or plastic treated with ultraviolet light protectants also helps minimize this damage.

Beyond the kitchen, sunflower oil has many surprising applications. The process of extracting oil leaves behind crushed seeds known as seed meal. This meal is rich in protein and dietary fiber, making it useful as animal feed, fertilizer, or fuel. The oil itself can be mixed with diesel to run diesel engines. In the European Union, sunflower oil is used in horticulture. It can be sprayed onto tomato crops as a fungicide to control a condition called powdery mildew. In this role, it is classified as a "basic substance" for both organic and conventional farms.

Modern science continues to explore the sunflower genome to improve oil production. A 2017 genome analysis helped scientists develop hybrid sunflowers. This research identified traits like flowering time and oil metabolism. Scientists also identified phytochemicals within the plant metabolism. These include polyphenols, squalene, terpenoids, and phytosterols. These complex molecules contribute to the biological identity of the plant and its resulting oil.
