abstract = {This study is focused on the characterization of thermal behavior and physical properties of most consumed legumes in daily diet such as beans, lentils and chickpeas. Because of a lack of knowledge in literature about the effect of microwave treatments on legumes, characterization protocols have been applied before and after subjecting them to microwave irradiation suitable for pest disinfestation. The effects of two different radiative treatments, one suitable to inactivate the infesting fauna, and one simulating uncontrolled treatments, characterized by very high temperatures, were tested. The impacts of microwave treatments on legumes, in terms of thermal behavior, germination capability, tannin and total polyphenols composition and other physical properties (water uptake capability, texture change, mineral losses), after typical soaking cooking processes, are also performed. Examined legumes thermal properties were found comparable for all samples. Similarly, no significative differences in antinutritional factors, polyphenols and tannins, content among all samples were detected. Under structural point of view, samples exposed to high temperatures have been shown a texture degradation and in turn, losses of mineral nutrient during soaking processes. Moreover, their germinative capability was drastically reduced. These latter results highlighted how is important to correctly perform radiative microwave process in order to both assure an effective and safe disinfestation and avoid nutritional values losses and physical properties worsening.},

abstract = {The effects of microwave assisted drying on banana fruit was evaluated. Water, reducing sugars, and polyphenol contents, as well as poly-phenol-oxidase activity were evaluated along the radial and axial positions in thick slices of banana, according to a properly defined cutting and assaying protocol. The effects of the microwave-assisted drying process were compared to the convective air-assisted drying resulting faster than the conventional process. In particular, the resulting samples were homogeneous in the water content; the contents of reducing sugars were strongly decreased on drying with microwaves; the poly-phenol-oxidase was inactivated by the high temperature produced by the process and thus the polyphenols content remained practically the same as in the fresh product.},
