Chemical Correlations Between Industrial Curds and Final Cheeses. Can Cheesemakers Standardise Productions?
2016
The chemical composition of milks and curds influences the microbial ecology and chemical features of produced cheeses. This statement is quite obvious because ‘normal’ cheeses—products with a prevailing ingredient, milk—are obtained by means of the transformation of the main raw material and the addition of minor components. Because of the possible scarcity of readily available milk in many regions or economic areas, the industry of milk and dairy products, including cheeses, has improved the production of ready-to-use curds. These products, also named ‘industrial curds’, are produced exclusively for further cheesemaking processes. For this reason, ready-to-use curds are pre-packaged with …
Physico-Chemical Stability of Admixtures of Vinflunine Used in Clinical Practice.
2021
Procedure of administration of vinflunine is complex and consists of an Y-site injection with fluid at different speeds. Dose is diluted with 100 mL of 0.9% sodium chloride or 5% glucose and infused with half of the 500 mL bag of the fluid over 20 min; after that, the remaining fluid is administered at 300 mL/h. In this study, chemical stability and physical compatibility of vinflunine diluted with in 500 mL of both fluids were evaluated to simplify the administration procedure (infusion of mixture on 20 min followed by 250 mL of fluid at 300 mL/h). Physical compatibility and chemical stability were evaluated at two temperatures and protected from and exposed to light. Physical compatibilit…
Non-isothermal thermogravimetry as an accelerated tool for the shelf-life prediction of paracetamol formulations
2021
Abstract In this work, non-isothermal thermogravimetric studies have been carried out on several paracetamol formulations with the aim to predict their shelf-lives under variable storage conditions. Specifically, paracetamol tablets of different brands have been investigated allowing to estimate their pharmaceutical quality by considering the specific drug stability. The proposed protocol is based on the kinetic study of thermogravimetric data by the combination of isoconversional procedures (Friedman and Kissinger-Akahira-Sunose (KAS) methods) and “Master plot” analysis. Accordingly, the kinetics of the paracetamol degradation is totally explored in terms of activation energy, pre-exponent…
