Antioxidant capacity of frozen Pleurotus ostreatus during convective drying
(Universidad de Puebla, México, 2016-01)The influence of drying conditions on antiradical power, total phenols, flavonoids, and surface color in frozen basidiocarps of Pleurotus ostreatus was studied. Drying was carried out in an experimental rig, air velocity ... -
Calculation of the effective diffusion coefficients in drying of chemical and mechanical pretreated Rosehip Fruits (Rosa eglanteria L.) with selected mass transfer models
(De Gruyter, 2013-11-20)The aim of this work was to select models of mass transfer to estimate effective mass diffusion coefficients during the dehydration of Rosa eglanteria fruits with air at 70°C. Fruits were pretreated chemically and mechanically ... -
Desecado de frutas y hortalizas a nivel familiar
(EEA Alto Valle, INTA, 2016-12)La conservación de alimentos tiene como objetivo prevenir o evitar el deterioro que provocan agentes físicos, químicos o biológicos. De esta forma se mantienen intactas las propiedades nutricionales y organolépticas (color, ... -
Drying kinetics of frozen oyster mushrooms (Pleurotus ostreatus)
(Universidad de Puebla, México, 2016-07)The kinetics of drying of frozen oyster mushrooms (Pleurotus ostreatus) was evaluated. Air temperatures of 50 C, 60 C and 70 C, at 2 m/s and 5% relative humidity, were used for drying experiments. In this work, we studied ... -
Effect of perforation on drying kinetics of Rosa rubiginosa fruits
(Asian Academic Research Associates, 2015-10)The effect of perforation and drying air operating variables on drying kinetics of Rosa rubiginosa fruits was investigated. Before drying, half the fruit sample was perforated in order to speed up the drying process. Samples ... -
Effect of structural modifications on the drying kinetics of foods: changes in volume, surface area and product shape
(ISEKI Food Association, 2013-10)Macro and micro-structural changes take place during food dehydration. Macro-structural changes encompass modifications in shape, area and volume. Studies of such changes are important because dehydration kinetics (essential ... -
Effects of pretreatments in convective dehydration of Rosehip (Rosa eglanteria)
(ISEKI Food Association, 2012-02)The aim of this work was to experimentally determine drying curves for thin layer and bed drying of rosehip fruits, with and without pretreatments, to reduce processing times as a function of drying air operating variables, ... -
Pretreatments Effect in Drying Behaviour and Colour of Mature and Immature ‘Napolitana’ Sweet Cherries
(Springer, 2014-06)The effect of different treatments on drying behaviour and colour of mature and immature cherries (Napolitana var.) has been studied. Drying was carried out at 70 °C with air at 4 m/s speed and 8 % relative humidity, and ... -
Rehydration of Rosa rubiginosa Fruits Dried with Hot Air
(Taylor & Francis, 2015-03)The effect of perforation, drying temperature, and rehydration temperature on the rehydration kinetics of Rosa rubiginosa fruits was investigated. Before drying, half of the fruit sample was perforated three times at ... -
