Sunflower seed oil is a common edible oil, which is widely welcomed because of its healthy characteristics. There are two main methods to produce sunflower seed oil: pressing and extracting.

First of all, the pressing method is a traditional mode of production. It extrudes the oil from sunflower seeds by mechanical pressure. According to the different production temperatures, it can be divided into hot pressing and cold pressing. The specific steps of pressing method include cleaning, shelling and pressing. Cleaning is to remove impurities and improve the purity of oil; Shelling is for better pressing. In the process of pressing, sunflower seeds are treated by high pressure, and oil is squeezed out to form primary pressed oil. Primary pressed oil usually has high nutritional value, but its output is low.

Secondly, extraction is a modern production method, which uses chemical solvents to extract oil. This process includes soaking, extraction, separation and other steps. Sunflower seeds are first soaked in a solvent to dissolve the oil in the solvent, and then the oil is separated from the solvent by separation technology. Extraction can improve the output, but it may affect the quality of oil in some cases.

Although pressing method and extraction method have their own advantages and disadvantages, both of them can produce high-quality sunflower seed oil. Pressing method retains more natural nutrients, such as vitamin E and unsaturated fatty acids, while extraction method can extract oil more efficiently, which is suitable for mass production.

When choosing sunflower seed oil, consumers can choose products with different production methods according to their own needs. If you pursue nature and nutrition, you can choose sunflower seed oil produced by pressing method; If we pay attention to cost performance and output, we can consider the products produced by extraction.

In a word, the production method of sunflower seed oil affects its quality and characteristics. Understanding these production processes will help consumers make more informed choices and enjoy a healthy and delicious eating life. No matter which method you choose to produce sunflower seed oil, eating it in moderation is an important part of a healthy diet.
