[ES] «Aplicación de nuevas tecnologías a la alcalinización de cacao» es una tesis doctoral centrada, por un lado, en el estudio de los cambios fisicoquímicos y funcionales causados por dos técnicas de alcalinización ...

[EN] The production of carbon fibers based on Polyacrylonitrile (PAN) precursor fibers is a very energy intensive process. In order to increase the energy efficiency, microwave plasma processes and, alternatively, ...

A microwave cavity and heating system for microwave processing and in situ dynamic measurements of the complex permittivity of dielectric materials at high temperatures (~1000ºC) has been developed. The method is based on ...

[EN] The evolution of dielectric properties of starch-based food pellets with different moisture contents was measured during microwave expansion to determine the effect of water content on the expansion dynamics. Dynamic ...

[EN] Both high temperature phases and microstructure transformations of stoneware products microwave and conventionally (gas and electric) fired are investigated aiming at a better understanding of factors affecting their ...

[EN] It is well known that microwaves can assist most of food drying processes; but despite its benefits, microwave energy has not yet been exploited to its potential in the industrial applications. Some of the reasons are ...

The inactivation of Listeria monocytogenes in a kiwifruit puree by conventional and microwave heating was studied. Survival curves at three microwave power levels (600 1000 W) and three temperatures (50 60 °C) were ...

[EN] The development and optimisation of food preservation processes seem to be necessary in order to address consumer expectations related to secure, fresh-like foods. To this end, the sensory, nutritional and functional ...

This paper describes the microstructure and dielectric properties of white sauces prepared with different fats (sunflower oil, olive oil, soy oil, and butter) and agitation speeds (350, 1100 and 3250 rpm). The structural ...
