Thermal behavior and decomposition kinetics of rifampicin polymorphs under isothermal and non-isothermal conditions

The thermal behavior of two polymorphic forms of rifampicin was studied by DSC and TG/DTG. The thermoanalytical results clearly showed the differences between the two crystalline forms. Polymorph I was the most thermally stable form, the DSC curve showed no fusion for this species and the thermal decomposition process occurred around 245 °C. The DSC curve of polymorph II showed two consecutive ...

Isothermal and Non-isothermal Methods

a comparison was made between the experimental non-isothermal a vs. t curves and those calculated on the basis of a previous isothermal study. It was observed that for low heating rates, when the "thermal lag" is negligible, the dynamic measurements are in good agreement with the isothermal ones. Furthermore, for process (I), two mathematical methods proposed for the interpretation of the non-i...

Thermal inactivation of Listeria monocytogenes in ground beef under isothermal and dynamic temperature conditions

0260-8774/$ see front matter Published by Elsevier doi:10.1016/j.jfoodeng.2008.07.011 E-mail address: [email protected] The objective of this research was to compare the suitability of three kinetic models for describing the survival of a cocktail of Listeria monocytogenes in ground beef under both isothermal and dynamic temperature conditions. Ground beef (93% lean), inoculated with a 4...

Formation kinetics of hydroxymethylfurfural, lactulose and furosine in milk heated under isothermal and non-isothermal conditions.

A detailed kinetic study of hydroxymethylfurfural, lactulose and furosine formation was performed upon heating milk at temperatures between 90 degrees C and 140 degrees C. In case of prolonged heating, formation kinetics could be described by a fractional conversion model. Considering only the first phase of the model, kinetics could be simplified to a pseudo-zero order model. A first assessmen...

Use of modified Richards model to predict isothermal and non-isothermal microbial growth.

Mathematical models are often used to predict microbial growth in food products. An important class of these models involves the adaptation of classical sigmoid functions, such as the Gompertz and logistic functions. This study aimed to validate the use of the modified Richards model in various situations, which have not previously been tested. The model was obtained through solving a system of...
