Modeling the reduction of pectin methyl esterase activity in orange juice by high intensity pulsed electric fields
(Elsevier, 2007-01)Orange juice was processed by high intensity pulsed electric fields (HIPEF) at different processing conditions: electric field strengths (E) from 5 to 35 kV/cm up to 1500 mu s of total treatment time (t) using pulses of 4 ... -
Modelización cinética de la degradación fotoquímica de benomilo
(Asociación de Químicos del Instituto Químico de Sarriá, 2015)En muchos zumos de frutas y soluciones acuosas aparecen restos de plaguicidas que pueden resultar peligrosos para la salud de los consumidores, por lo que es necesario realizar tratamientos de eliminación de estos ... -
Modelling Aspergillus flavus growth and aflatoxins production in pistachio nuts
(Elsevier, 2012)Aflatoxins (AFs) are the main contaminants in pistachio nuts. AFs production in pistachio has been attributed to Aspergillus flavus. The aim of this study was to apply existing models to predict growth and AFs production ... -
Modelling mould growth under suboptimal environmental conditions and inoculum size
(Elsevier, 2010)Predictive models can be a tool to develop strategies to prevent mould development and consequently mycotoxin production. The aims of this work were to assess the impact of a) high/low levels of inoculum and b) optimal/suboptimal ... -
Modelling of patulin photo-degradation by a UV multi-wavelength emitting lamp
(Elsevier, 2014)In this paper, a newmechanism is proposed to describe the degradation of patulin using UVradiation froma midpressure lamp with emission wavelengths between 250 and 740 nm. The mechanism consists of three stages:excitation ... -
Modelling the effect of pH and water activity in the growth of Aspergillus fumigatus isolated from corn silage
(The Society for Applied Microbiology, 2017)Aims: The aim of this work was to use mathematical kinetic modelling to assess the combined effects of aW, pH, O2 availability and temperature on the growth rate and time to growth of Aspergillus fumigatus strains isolated ... -
Modelling the effect of temperature and water activity in the growth boundaries of Aspergillus ochraceus and Aspergillus parasiticus
(Elsevier, 2011)The aim of this work was to model the growth of Aspergillus parasiticus and Aspergillus ochraceus, both mycotoxin producers, near to the growth/no growth boundaries and validate those models in sterile maize grain, peanuts ... -
Modelling the effect of temperature and water activity of Aspergillus flavus isolates from corn
(Elsevier, 2011)The aim of this study was to model the effects of temperature (10–40 °C) and aw (0.80–0.98), in two media (Czapek yeast agar: CYA; corn extract medium: CEM) on the growth rates and growth boundaries (growth–no growth ... -
Modelling the Probability of Growth and Aflatoxin B1 Production of Aspergillus Flavus under Changing Temperature Conditions in Pistachio Nuts
(Elsevier, 2016)The aim of this work was to use probability models for the prediction of growth and aflatoxin production by Aspergillus flavus as a strategy to mitigate the aflatoxin presence in pistachio nuts during postharvest. Logistic ... -
