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 ... -
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, ... -
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, ...
