New method quickly determines quality of linseed oils for better health.
The article discusses a new method for quickly checking the quality of linseed oils by measuring the amount of linolenic acid using nuclear magnetic relaxation. Linseed oils with high linolenic acid content are considered better quality. The study compared this new method with gas-liquid chromatography and found that the nuclear magnetic relaxation method is more efficient for determining linolenic acid levels in linseed oils. This method can help ensure linseed oils meet high-quality standards.
