“…Recently, ultrasound treatment during olive oil extraction has been studied by several researchers (Bejaoui et al, 2016(Bejaoui et al, , 2015Clodoveo and Hachicha Hbaieb, 2013;Clodoveo, 2012;Clodoveo et al, 2013b;Jiménez et al, 2007;Jiménez Márquez et al, 2006). Although these authors studied the ultrasound as a part of malaxation, the optimal conditions of ultrasound temperature, ultrasound time and malaxation time for an ultrasound assisted extraction of extra virgin olive oil were unknown.…”

“…The importance of the olive oil sector in the main producing countries is well known, as is the case of Spain, where 47% of the worldwide consumed olive oil is produced. It should also be borne in mind that the type of cropping system is gradually changing from traditional to intensive or even super-intensive in order to increase production [1]. All this leads to the production of between 5 and 7 million tons of by-products per year in Spain while simultaneously exhausting agronomic resources more rapidly, forcing the use of a larger quantity of fertilizers.…”

“…This is the most commonly used system in Spain and other olive oil-producing countries and allows for the generation of a solid with a high percentage of moisture (above 65% on average). Between three and seven million tons of alperujo are generated per year in Spain, which produces almost half of the olive oil consumed worldwide [1]. Although great efforts have been made to minimize its environmental impact, with combustion being the most widely used resource, not all the interesting components in alperujo have been exploited and pollution has not been completely avoided.…”
