- Abstract
- The spectrophotometric techniques allow to determine instantaneously the concentration of chemical species without sample preparation and transformation, The application of these techniques, notably the near infrared spectroscopy in quality control of food industry has been developed by numerous laboratories and companies for more than twenty years. The analytical performances of new spectrophotometers in measurement of fluorescent and Roman emission as well as near infrared absorption ore presented here in order to explain how these instruments answer the needs of fast analysis and on-line quality control in the oils and fats domain. Equipped with fiber optics and coupled charge device detectors, the lost generation of spectrophotometers named spectrophotometric sensors or spectrosensors suit the immediate and non-destructive chemical analysis of fats and oils with the determination of parameters such as total lipids, free fatty acids for the near infrared spectrometry, polyphenols and chlorophyl for the spectrofluorimetry and trans fatty acids for the Roman spectroscopy.
