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 ... -
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 ... -
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, ... -
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 ... -
Sorption characteristics of rosehip, apple and tomato pulp formulations as determined by gravimetric and hygrometric methods
(Elsevier, 2013-06)The sorption characteristics of three formulations based on rosehip, apple and tomato pulp, added with saccharides, and aimed at preparing fruit leathers, were studied. Desorption isotherms were determined at 20 and 40 °C, ...
