An admixture of cheap rapeseed oil changes the spectrum of olive oil in a few narrow spectral ranges. This article is a placeholder: fill it in with the admixture detection threshold, spectra charts for pure vs. adulterated oil, and a description of the test methodology.
To fill in
- The spectral ranges most sensitive to rapeseed oil admixture.
- The lowest detected admixture percentage.
- Comparison against a reference method (e.g. chromatography).
- Limitations of the method — when the measurement can give a false result.
