Salt release monitoring with specific sensors in "in vitro" oral and digestive environments from soft cheeses
International audience; The objective of the present work is to demonstrate the interest and the feasibility of the measurement of NaCl concentrations in soft cheeses and in particular an in vitro digestion process by the use of chemical sensors. The analyzed matrices were the commercial Italian mozzarella cheeses and domestic cheese base models. The classification of mozzarellas was performed according to their salinity, while the breakdown of cheese base models has been followed both at initial steps of digestion in artificial mouth dispositive mimicking the oral sphere and in a gut-imitating digester (TIM-1). During the breakdown of soft cheese in the digester, the estimated values for N…
The Difficult Marriage of Triarylcorroles with Zinc and Nickel Ions.
The coordination chemistry of corrole has witnessed a great improvement in the past few years and its Periodic Table has been widened to be so large that it is compared with that of porphyrins. However, Ni and Zn ions, commonly used with porphyrins for both synthetic and theoretical purposes, are sparsely reported in the case of corroles. Here, we report synthetic protocols for preparing Ni and Zn triarylcorrole complexes. In the case of Zn, the preliminary oxidation of the free base corrole in DMSO to the neutral corrole radical is a necessary step to obtain the coordination of the metal ion, because the direct reaction led to the formation of an open-chain tetrapyrrole. The Ni complex cou…
Electrochemistry of Mono- and Bis-CN Ligated Cobalt Corroles
International audience; The electrochemical properties of numerous transition metal corroles have been examined under a variety of<br>solution condition with special emphasis being placed on the innocent or non-innocent nature of the corrole<br>macrocycle. This property, as well as the half-wave potentials and sites of electron transfers, are known to be<br>strongly influenced by the type of central metal ion and degree of axial coordination, namely 4, 5 or 6-coordinate.<br>The redox potentials of metallocorroles are also dependent upon the solvent and inductive, resonance or steric<br>effects dictated by peripheral substituents at the meso or β-pyrrole positions of the corrole li…
