Valorization of a high-acidity residual oil generated in the waste cooking oils recycling industries
(Consejo Superior de Investigaciones Científicas, CSIC: Instituto de la Grasa, 2019)
A sludge fraction is obtained from the industries which recycle cooking oil and this sludge con-tains a large amount of oil with an extremely high acidity (> 60%). In this work, we propose a scheme for methyl ester production ...

Olive oil nutritional labeling by using Vis/NIR spectroscopy and compositional statistical methods
(Elsevier, 2019)
Food nutritional labeling is compulsory in the European Union since 13 December 2016. The olive oil fatty acid composition shows high variation depending mainly on the variety. Thus, olive oil nutritional labeling is ...

Sorting olive oil based on alpha-tocopherol and total tocopherol content using near-infra-red spectroscopy (NIRS) analysis
(Elsevier, 2017)
Olive oil is an important vitamin E source, which shows a wide variation range. Therefore the interest on distinguish classes. In this study, we assessed models based on partial least squares (PLS) and discriminant analysis ...

Biodiesel production from waste cooking oil in an oscillatory flow reactor. Performance as a fuel on a TDI diesel engine
(Elsevier, 2018-09)
This paper describes the biodiesel production from waste cooking oil (50% (v/v) olive oil/sunflower oil) in an oscillatory flow reactor (OFR) in batch mode. We mainly focused on the characteristics of the biodiesel and ...
