El remojado es una etapa fundamental en la preparación de soja previo a su consumo. Los objetivos este trabajo fueron estudiar cinética y evaluar el efecto temperatura sobre los inhibidores tripsina. Las experiencias consistieron remojar un baño termostático, diferentes temperaturas, entre 20 80ºC extrayendo muestras 0 300 min. Para modelado matemático se propuso balance materia estado no estacionario que consideró coeficiente difusión variable expansión volumétrica mediante correlación...
ABSTRACT Experiments on thin‐layer drying of wheat were interpreted in terms a kinetic model based internal control for water transfer and absence temperature gradients inside the kernel. The operation batch fluidized bed was modelled by assuming perfect mixing solids. parameters obtained from runs introduced into this allowed to interpret satisfactorily experiments performed bed. Predictions showed that times could be decreased about four fold raising air 40°C 70°C. It also calculated inlet...
Summary For the development of fruit leathers, a formulation containing rose hip pulp, sucrose and citric acid was used as initial material for drying process. Three dehydration techniques were tested: forced hot air, infrared vacuum, all carried out at 60 70 ° C . All methods led to flexible, translucent leathers both temperatures. Colour water activity not affected by method nor temperatures tested. Nutritional parameters such antioxidant capacity ( TEAC ) content phenolic substances...
ABSTRACT A mathematical model of heat and mass transfer for fixed beds was developed according to the modern theory process simulation standard laws thermodynamics transport phenomena. The grain-air predicted with simplified diffusional expressions together an equation static equilibrium moisture content. Four differential equations were obtained a grain layer they integrated along bed depth time second fourth-order methods, respectively. validated by comparing drying predictions...
The sorption characteristics of three formulations based on rosehip, apple and tomato pulp, added with saccharides, aimed at preparing fruit leathers, were studied. Desorption isotherms determined 20 40 °C, both by the static gravimetric hygrometric method. Experimental all J-shaped, as expected for rich-sugar matrices. A model previously developed leather isotherms, GAB equation Halsey fitted to data. Hygrometric exhibited a typical behavior high moisture contents although, lower values,...
