Scientists uncover cancer-causing chemicals hidden in everyday foods
Researchers have discovered cancer-causing chemicals, specifically polycyclic aromatic hydrocarbons (PAHs), in many common foods, particularly those cooked at high temperatures. These compounds can form during cooking or enter foods through environmental contamination, raising health concerns. A new testing method, QuEChERS, has been developed to detect these harmful chemicals more efficiently in food samples.
- ▪PAHs can form when food is exposed to high temperatures or smoke.
- ▪The new QuEChERS method simplifies the detection of PAHs and shows high efficiency compared to traditional methods.
- ▪The highest PAH levels were found in soybean oil, duck meat, and canola oil.
