“…The variation in entropy (4S) was also inversely proportional to the temperature, with a low modulus, but consistent throughout the range evaluated, following the principle that entropy is only related to temperature change. When the entropy values are high, such as those obtained for the trapi a residues, the material is far from thermodynamic equilibrium (Santos & Morais, 2015). Negative values for entropy are attributed to the existence of chemical adsorption and/or structural modifications of the adsorbent (Moreira, Chenlo, Torres, & Vallejo, 2008).…”

“…The drying process is characterized as nonspontaneous, requiring the addition of energy, supplied by the drying air, to promote a reduction in the moisture content (Maia et al, 2019). Santos and Morais (2015), when drying orange peel, obtained values for the variation in Gibbs free energy of between 161.00 and 230.00 kJ mol À1 K À1 , and when drying jabuticaba peel, Costa et al (2016) obtained 4G values of between 34.56 and 34.80 kJ mol À1 K À1 .…”

“…A Tabela 1 apresenta a frequência dos principais picos de transmitância obtidos e os respectivos grupos funcionais, que podem ser responsáveis pela ligação de íons de ferro na superfície da casca de laranja liofilizada, o que está de acordo com a alta complexidade do material [41].…”
