Determinação Do Equilíbrio Higroscópico E Do Calor Isostérico Da Polpa E Da Casca Do Abacaxi

Abstract: Com o intuito de analisar a dinâmica de sorção e de energia necessária para o processamento do abacaxi (Ananas comosus), o presente trabalho teve como objetivo a determinação do equilíbrio higroscópico e do calor isostérico da casca e da polpa do abacaxi, a partir de diferentes condições controladas de temperatura e umidade relativa do ar, assim como avaliar, dentre diversos modelos descritos na literatura, o que melhor representa o comportamento de sorção do abacaxi e da casca do abacaxi, e o calor latente de… Show more

“…In accordance with Teixeira et al (2012), the mathematical models obtained in the literature for the hygroscopicity of agricultural products used for hot pepper analysis were chosen at random as a function of the temperature and the relative humidity of the air to check which model best represented its isotherm. The models used are shown in Eqs.…”
