Gas chromatography (GC) is an analytical technique used to separate and detect the chemical components of a sample mixture to determine their presence or absence and/or quantities. These chemical components are usually organic molecules or gases.
In the food and oil processing industry, maintaining the quality and safety of edible oils is crucial. One of the most significant indicators of oil degradation during use, especially during frying, is the formation of Total Polar Compounds (TPCs) . These compounds play a vital role in determining whether the oil is still suitable for consumption or needs to be discarded. What Are Total Polar Compounds? Total Polar Compounds are a group of substances formed when edible oils are exposed to high temperatures, such as during deep frying. Over time, heat, oxygen, and moisture cause the oil to break down, resulting in the formation of polar substances like oxidized triglycerides, free fatty acids, mono- and diglycerides, and polymerized triglycerides. These compounds increase with repeated oil use and indicate oil degradation, reduced nutritional value, and the potential formation of harmful substances. Why Is TPC Measurement Important? Monitoring TPC levels is essential for both food safe...
