Cold-pressed soybean oil is a popular choice among chefs and food manufacturers for its high smoke point, rich nutrients, and non-GMO status. However, like all oils, it is prone to oxidation, which can lead to a loss of flavor and nutritional value. In this article, we'll explore the science behind oil oxidation and share practical tips on how to preserve Shandong Ruihe Douyuan Cold-Pressed Non-GMO Soybean Oil to prevent oxidation and extend its shelf life.
Oxidation is a natural process that occurs when oil is exposed to oxygen, light, heat, and moisture. This process breaks down the oil's fatty acids, leading to the formation of free radicals, which can cause off-flavors, odors, and a decrease in nutritional value. Oxidized oil can also pose health risks, as free radicals can damage cells and contribute to chronic diseases.
To understand how to prevent oxidation, it's important to know the factors that accelerate it. For example, light can trigger the oxidation process, while heat can speed it up. Moisture can also promote the growth of bacteria and mold, which can further degrade the oil. By controlling these factors, you can significantly extend the shelf life of your cold-pressed soybean oil.
Shandong Ruihe Douyuan Cold-Pressed Non-GMO Soybean Oil is produced using a cold-pressing process at a temperature of ≤60°C, which helps to preserve the oil's natural nutrients and antioxidants. This process also eliminates the use of chemical solvents, ensuring a pure and natural product. With an acid value of ≤0.2 mg KOH/g, this oil has a lower level of free fatty acids, making it more stable and resistant to oxidation.
The oil is also certified by ISO22000/HACCP, which means it meets strict international standards for food safety and quality. These certifications ensure that the oil is produced in a clean and controlled environment, further enhancing its stability and shelf life.
