Extração do óleo da polpa do abacate com Metanol e Etanol a diferentes temperaturas Alessandro Cazonatto Galvão Milena Copetti Camilla Dal Magro Sidiane Iltchenco Weber da Silva Robazza Estudios Ambientales óleo Abacate extração modelagem O objetivo do presente trabalho consistiu na extração do óleo da polpa do abacate de variedade Hass utilizando como solvente o etanol e o metanol. Os experimentos foram conduzidos a pressão atmosférica e no intervalo de temperatura entre 283,15 K e 313,15 K. As extrações foram realizadas por um período de 10 horas com amostragens a diferentes tempos de extração. Para ambos os solventes a capacidade de extração apresentou resultados crescentes com o aumento da temperatura. O solvente etanol mostrou maior capacidade de solubilização do óleo da polpa do abacate. Os resultados experimentais foram correlacionados a um modelo que considera que o processo de extração ocorre por dois fenômenos; primeiro o óleo que está na superfície do sólido é rapidamente solubilizado pelo solvente e segundo o óleo residual é removido do interior do sólido por processo difusional. 2013 artículo científico 0100-8307 https://www.redalyc.org/articulo.oa?id=467546171029 pt http://www.redalyc.org/revista.oa?id=4675 Ciência e Natura application/pdf Universidade Federal de Santa Maria Ciência e Natura (Brasil) Num.2 Vol.35
