Lessons Learned and Concluding Remarks
摘要
In recent years, the primary objectives in the olive oil extraction process have been to increase yield and reduce kneading time. Adding more than one malaxer to the system and utilizing a heat exchanger have been shown to increase kneading efficiency. Such interventions at various processing steps, in combination with other approaches, such as controlled exposure to oxygen, have been utilized to improve yield and quality. The moisture content of the paste has also been considered, in addition to the commonly studied parameters, including temperature, ripening index, time, water dilution, and processing aids during malaxation. The effects of these variables were also evaluated by measuring parameters such as droplet size and coalescence [1].
