The productivity of virgin olive oil depends not only on agronomic factors but
also on the technological factors of the extraction process. The ‘Arbequina’
variety has extractability problems, which is a challenge for master millers
anywhere. This work aims to evaluate the behavior of different decanters and
seeks to modulate the effect of some processing parameters and their
interactions with oil extraction efficiency in the case of ‘Arbequina.’ Fruit
characteristics, processing parameters, and extractability were collected over
10 years from 38 decanters that belong to five different brands. The results have
shown that fruit moisture is the most relevant factor for oil extractability,
especially over 52%. Furthermore, extractability is positively correlated with
malaxing temperature, addition of water, and total fat content in the fruit.
However, the results show that before applying a regulation, the type of
decanter must be considered. The model used in this study has allowed us to
optimize the regulations for each type of decanter to reduce oil losses within the
pomace, achieving an extraction efficiency within the range of 78%–91.5%. In
fact, the best extraction efficiency results (91.5%) were obtained by processing at
temperatures >26°C and water injection of 5%.
