MICROBIOLOGICAL QUALITY OF SOUS VIDE COOK-CHILL PRESERVED FOOD AT DIFFERENT SHELF LIFE
The effect of three different periods of storage life (0, 15 and 30 days) on the microbiological quality of several foods elaborated with the sous vide cook–chill procedure in a restaurant was studied. These foods are grouped in three categories: meat (breast chicken, foie gras, pork loin and entrecote of veal), fish (codfish, gilt head sea bream, hake and salmon) and vegetable (broccoli, courgette, potato and carrot). Total plate counts in the products studied were in the range of <1.00–3.74 log10 cfu/g. Coagulase negative staphylococci were isolated in the three categories, Enterococcus spp. were isolated from foie gras and Pantoea agglomerans from salmon and carrot. Staphylococcus aureus…
Evaluación de la presión plantar en cinta rodante y suelo durante la marcha
Resumen La evaluacion clinica de la presion plantar durante la marcha se realiza tanto en cinta rodante como en pasillo de marcha. Sin embargo, las posibles diferencias en el patron de presiones plantares entre ambos medios no esta totalmente esclarecido. El objetivo del presente estudio ha sido evaluar el efecto de la cinta rodante sobre las presiones plantares a tres velocidades de marcha (lenta, media y alta). Participaron 25 sujetos sanos. Para registrar las presiones plantares se utilizo un sistema de plantillas instrumentadas Biofoot/IBV que se colocaban en un calzado deportivo estandar. La cinta rodante utilizada fue un BH fitness modelo ColumbiaPro de 1.600 W de potencia y el pasill…
Determination of enzymatic activities using a miniaturized system as a rapid method to assess soil quality
Soil quality determination requires the analysis of a number of soil attributes using different approaches. In recent years, one of the most promising approaches has been the determination of enzymatic activities. Generally, only a few enzymes have been analysed and related with other parameters, such as total carbon, nitrogenous content or microbial biomass carbon. The aim of this work was to investigate the possible use of the API ZYM strip, a semi-quantitative miniaturised system that determines 19 enzymatic activities, to study soil quality. To this end, we tested the system in different soil types, including albicArenosols, mollicLeptosols, rendzicLeptosols, haplicLeptosols, and calcar…
