Delineation of the structure of soft cheeses at the molecular level by fluorescence spectroscopy—relationship with texture

Influence of storage time and color of light on photooxidation in cheese: A study based on sensory analysis and fluorescence spectroscopy

“…Riboflavin, beta-carotenoid, chlorophyll, and porphyrin compounds all absorb in this region, which means that photodegradation of these pigments might introduce changes in the fluorescence spectra due to more or less reabsorption of the fluorescence by these compounds. Finally, vitamin A, which is also light sensitive, has a fluorescence emission maximum around 411 nm (Christensen, Povlsen, & Sørensen, 2003; Dufour, Devaux, & Herbert, 2001). However, the emission intensity for vitamin A for excitation at 380 nm is expected to be negligible.…”

Feasibility study of discriminating the manufacturing process and sampling zone in ripened soft cheeses using attenuated total reflectance MIR and fiber optic diffuse reflectance VIS–NIR spectroscopy

“…Although, significant differences of pH, moisture, fat and nitrogen contents between the external (E) and central (C) zones of soft cheeses have been reported, all the studies about the potential of using spectroscopic techniques to study the molecular changes in soft cheeses have been performed without considering the effect of the sampling zones (Dufour, Devaux, Fortier, & Herbert, 2001;Herbert, 1999;Herbert et al, 2000;Kulmyrzaev et al, 2005). Recently, Verdini and Rubiolo (2002) and Verdini et al (2004) have investigated the effect of the sampling zones during the rip-…”

Investigation at the molecular level of soft cheese quality and ripening by infrared and fluorescence spectroscopies and chemometrics—relationships with rheology properties

“…A description of the structural characteristics of soft cheeses can also be achieved using fluorescence spectroscopy (Herbert et al, 2000;Dufour, Devaux, Fortier, & Herbert, 2001) and infrared spectroscopy. Fluorescence spectroscopy is a sensitive, rapid and non-invasive analytical technique that provides information on the presence of fluorescent molecules (Lakowicz, 1983).…”
