“…In order to accelerate the drying process to produce raisins, various chemical and physical pre-treatments have been investigated and applied (Adiletta et al, 2016;Jairaj et al, 2009). In the chemical pretreatments, often, an alkaline solution such as potassium carbonate is combined with other components such as olive oil (Telis, Lourençon, Gabas, & Telis-Romero, 2006) or ethyl oleate (Bingol, Roberts, Balaban, & Devres, 2012;Gabas, Menegalli, & Telis-Romero, 1999). However, the presence of residues of additives in the raisins can lead to human health problems (Adiletta et al, 2016).…”
