Cinética de secagem de raspas de abóbora

Abstract: ResumoO aumento pela busca por alimentos saudáveis, sem glúten e ricos em fibras abre oportunidade para a incorporação de olerícolas, como a abóbora. A secagem e o armazenamento são etapas essenciais para a obtenção de produtos de qualidade, contribuindo para minimização de perdas e, consequentemente, aumentando a vida útil dos produtos. Objetivou-se, com esta pesquisa, avaliar a cinética de secagem das raspas de abóbora em diferentes condições de secagem, bem como determinar suas propriedades termodinâmicas. … Show more

“…equally verified by Moura et al (2021) and Almeida et al (2020) whose results for entropy were similar and who considered that the decrease in ΔS occurred as a result of the decreasing water content of the product during drying, thus restricting the movement of the molecules. According to Tavone et al (2021) the negative values are related to changes in the structure of the material.The values for Gibbs free energy (ΔG) were positive indicating a non-spontaneous process, requiring the addition of energy from the air around the product in order to reduce the water content(Cabral et al, 2021). There was an increase in ΔG of about 4.5% with temperature between 50 and 70°C, and similar results were found byTavone et al (2021) on evaluating the convective drying of calabura (Muntingia calabura) peels.…”
