摘要：
Herein are disclosed methods and devices for evaluating the quality of oils (e.g., cooking oil or flying oil). The methods can provide an indication of the free fatty acid content of the oil. The methods use an optical interrogation device to provide an indication of free fatty acid based on quantitative measurements of optical reflectance from test zones on a sampling substrate.
