A System to Control the Atmosphere in the Headspace of the Malaxation Machine to Improve the Fatty Acid Composition of Extra Virgin Olive Oils
2015
In recent years, oxygen content regulation during malaxation has been noted as a process parameter. As concluded by many studies, the presence of oxygen during malaxation has a key role in for improving the quality of Extra Virgin Olive Oil (EVOO) in terms of volatile and phenolic components. There are, however, very few studies of the influence of oxygen in the malaxation machine headspace on the fatty acid composition of Extra Virgin Olive Oil (EVOO). The aim of this study is to evaluate the influence of oxygen in the malaxation machine headspace on Nocellara del Belice EVOO fatty acids. During of the malaxation process, the atmosphere inside the malaxation machine was modified by blowing…
Physico-Chemical Properties and Use of Waste Biomass-Derived Activated Carbons
2017
Activated carbons are widely used in different industrial processes for example as adsorbents or as support materials. Advantageously these carbons can be prepared from residual or waste biomass materials. Different raw material type and activation procedure plays an important role in the physico-chemical characteristics of activated carbon e.g. surface area, porosity and pore distribution. In this study, activated carbon has been prepared from lignocellulosic waste materials (e.g. saw dust, lignin residue) and characterized by a number of methods. Further, adsorption properties of carbons were evaluated. Adsorption capacity of dyes and metals was high (methylene blue dye 86 % and zinc meta…
