“…Licciardi et al (2005) reported that the triglycerides (oils) of coffee beans are mainly unaffected by roasting, suffering only slight hydrolysis and decomposition, with the release of fatty acids and the formation of volatile products. However, in darker roasted coffee, many cells break and oils may migrate to the surface (França et al, 2001), resulting in greater weight loss and decreases in ρ u .…”

“…Desta forma, todas as amostras encontram-se dentro do padrão, que é de no mínimo 25% (BRASIL, 1999). No trabalho realizado por Licciardi et al (2005) Na determinação do extrato aquoso das amostras de café solúvel obtiveram-se resultados acima de 25%, indicando que todas as amostras atendem ao padrão estabelecido pela portaria (BRASIL, 1999). De acordo com Pedro et al (1996), a variação nos teores de extrato aquoso é bastante comum, pois no café torrado e moído (em pó) os graus de torração e moagem podem variar conforme o processo utilizado.…”

“…Além disso, também pode variar a composição do café, de acordo com as variedades utilizadas, aumentando ou diminuindo o teor de extrato aquoso. Segundo o estudo de Licciardi et al (2005), o teor de extrato aquoso pode variar, inclusive, de acordo com a época da coleta das amostras do café. Em suas amostras, os teores de extrato aquoso variaram nas diferentes épocas do ano: em janeiro os teores variaram de 24,38% a 28,73%, em abril a variação foi de 25,13% a 35,83% e em julho de 24,57% a 37,88%.…”

“…These results are based on 2 facts; one is that more finely ground coffee is more tightly agglomerated for a given volume, resulting in a higher weight per volume and lower ρ u . The second is that dark roasting causes bigger volume increases with higher weight losses followed by lower ρ u (Licciardi, Pereira, Mendonça, & Furtado, ). With reference to ρ ap , dark‐roast ground coffee has a lower ρ ap due to a great loss of volatiles and release of CO 2 , and volume changes due to intense heat transfer and pyrolysis during a longer roasting period (Borges, Mendonça, Franca, Oliveira, & Correa, ; Toledo et al., ).…”
