MOISTURE SORPTION ISOTHERMS OF A PALM HEART AND PREDICTION OF ITS SHELF LIFE AND THERMODYNAMIC PROPERTIES ON THE BASIS OF THESE ISOTHERMS
Experiments on determination of the sorption isotherms of the heart of a palm at diff erent temperatures have been performed. Some mathematical models, available in the literature, were used to predict the hygroscopic behavior of the palm heart. The thermodynamic properties of the palm heart, such as its isosteric heat of sorption, were determined using the Clausius–Clapeyron equation, and the shelf life of the palm heart was calculated using the Heiss–Eichner prediction model equations with regard for the storage conditions of this product and the requirements for its packaging . The results obtained can be used for optimization of the methods of drying and preservation of palm hearts, which is essential for the enhancement of their quality and the successful promotion of them in the international market.
