Thermal studies on protein isolates of white lupin seeds (Lupinus albus).
Fontanari, G.G.; Martins, J.M.; Kobelnik, M.; Pastre, I.A.; Arêas, J.A.G.; Batistuti, J.P.; Fertonani, F.L.This study used TG, DSC, and SDS-PAGE techniques to study protein isolates (PIs) in the powder form obtained from lupin seeds flour Lupinus albus. Different methods of preparing PIs were tested, resulting in final products that were different only in relation to the yield and protein content. The results of the protein analysis by SDS-PAGE showed that the same protein fractions were present in the lupin seeds a...
Comparison of the dehydration kinetics of solid state compounds of 2-methoxyben...
Kobelnik,M.; Ribeiro,C. A.; Dias,D. S.; Bernabé,G. A.; Crespi,M. S.Divalent metal complexes of ligand 2-methoxybenzylidenepyruvate with Fe, Co, Ni, Cu and Zn as well as sodium salt were synthesized and investigated in the solid state. TG curves of these compounds were obtained with masses sample of 1 and 5mg under nitrogen atmosphere. Different heating rates were used to characterize and study these compounds from the kinetic point of view. The activation energy and pre-expone...
Molecular and thermal characterization of white lupin (Lupinus albus) protein i...
Fontanari, G.G.; Martins, J.M.; Kobelnik, M.; Pastre, I.A.; Fertonani, F.L.; Arêas, J.A.G.; Batistuti, J.P.In this work differential scanning calorimetry (DSC) and SDS-PAGE techniques were used to study protein isolates from white lupine seeds flour (Lupinus albus).
Thermoanalytical study of purine derivatives compounds
Schnitzler,E.; Kobelnik,M.; Sotelo,G. F. C.; Bannach,G.; Ionashiro,M.Thermal methods of analysis are now used in a very large range of scientific investigations. In this work simultaneous thermogravimetry-differential thermal analysis (TG-DTA), X-Ray powder diffractometry and infrared spectroscopy were used to study the derivative compounds of purine, i. e. aminophylline, theophylline, caffeine and uric acid. The results led to informations about the thermal stability and therma...
