Online monitoring of electrical conductivity of wine induced by ultrasound
(Taylor & Francis, 2016)
We assessed the effects of ultrasonic frequency, power, temperature and exposure time on the electric conductivity (EC) of wine to evaluate the feasibility of the online EC monitoring as an indicator to reflect the changes ...
Preliminary study of the effect of ultrasound on physicochemical properties of red wine
(Taylor & Francis, 2016)
Ultrasound is regarded as a potential alternative method for improving the quality of some wines. This study was initiated with the objective of evaluating the effects of ultrasound on some important physicochemical ...
Metal Accumulation by Jatropha curcas L. Adult Plants Grown on Heavy Metal-Contaminated Soil
Jatropha curcas has the ability to phytoextract high amounts of heavy metals during its first months just after seeding. Notwithstanding, there is scarce information about metal uptake by adult J. curcas plants. To shed ...
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 ...
Energetic Valorisation of Olive Biomass: Olive-Tree Pruning, Olive Stones and Pomaces
Olive oil industry is one of the most important industries in the world. Currently, the land devoted to olive-tree cultivation around the world is ca. 11 106 ha, which produces more than 20 106 t olives per year. ...
Esterification of Free Fatty Acids with Glycerol within the Biodiesel Production Framework
Companies in the field of the collection and treatment of waste cooking oils (WCO) for subsequent biodiesel production usually have to cope with high acidity oils, which cannot be directly transformed into fatty acid methyl ...
Production of Oxygenated Fuel Additives from Residual Glycerine Using Biocatalysts Obtained from Heavy-Metal-Contaminated Jatropha curcas L. Roots
This work aims to shed light on the use of two biochars, obtained from the pyrolysis at 550 C of heavy-metal-contaminated Jatropha curcas L. roots, as heterogeneous catalysts for glycerol esterification using residual ...
Antimicrobial effect of cleaning formulations of industrial interest on free-living cells and biofilms
(Asociación de Químicos e Ingenieros del Instituto Químico de Sarriá, 2014)
Las biopelículas son una fuente de contaminación de difícil eliminación debido a su resistencia a los procedimientos de limpieza y de higiene convencionales. En este trabajo se ha evaluado las propiedades antimicrobianas ...
Determination of the Acidity of Waste Cooking Oils by Near Infrared Spectroscopy
Waste cooking oils (WCO) recycling companies usually have economic losses for buying WCO not suitable for biodiesel production, e.g., WCO with high free acidity (FA). For this reason, the determination of FA of WCO by ...
Identification of Copper in Stems and Roots of Jatropha curcas L. by Hyperspectral Imaging
The in situ determination of metals in plants used for phytoremediation is still a challenge that must be overcome to control the plant stress over time due to metals uptake as well as to quantify the concentration of these ...
