These techniques will be further developed to prototype sensing technologies able to determine the potential for spoilage of meat products and the potential to detect the metabolites of food-borne pathogenic bacteria. </p> <p>All studies were performed with beef samples stored under different conditions. Studies using FTIR were performed in AUA (B1). In parallel with FTIR, analysis were performed with instruments provided by Videometer (B6) and Raman Spectrometry (B12); Indeed these two instruments were /are tested in beef samples stored under different conditions ; The data derived from videometerlab instrument analysis allowed to propose a quantitative analysis method of meat spoilage.</p> <p>Studies using the synchronous fluorescence spectroscopy (SFS) were realised in Enita Clermont (B5). After the assessing the potential of SFS to predict microbial quality of meat stored under different conditions, the Enita Clermont team proposed now after wavelengths excitation selection (375-390 nm) a portable fluorometer allowing to predict meat spoilage. Nonetheless, this prototype is actually working with one wavelength excitation, other excitation wavelength ranges ([275-290 nm], [320-340 nm] and [450-470 nm] ) have to be tested to propose the most robust portable spectrometer.</p> <p>Technobiochip (B10) is working about the application of the LibraNose (e-nose) for the simple and rapid detection of microbial metabolites indicative of meat quality. TB e-nose is an instrument used to classify and identify complex odours. Basically is composed by an array of non selective sensors and a data analysis system. TB has performed the quartz crystal microbalances functionalization using the chemical poly-pyrrole compounds synthetized during the first 6 months. Concerning the functionalization, to obtain an ordered monolayer, an important parameter to take in consideration is the order of the organic molecules at the air-water interface. So, to obtain that information they studied the so called isotherm curve that is characteristic for each chemical compounds. </p> </h3> </div> </h:form> </p> </div> </div> </ui:define> </ui:composition> </html>
