Resourcing potential of olive oil pomace

Abstract

Olive oil is a kind of high-quality edible oil obtained by quick extraction from the fresh olive fruit. It has rich biological activity and positive effect on human health which leads to the increase of the demand for olive oil. Olive pomace is a by-product of olive oil during processing which is also rich in biologically active ingredients. But it is often treated as waste, not only causes environmental pollution but also a great waste of resources. In order to explore the high value utilization of olive oil by-products, the extract components of olive oil pomace by benzene, ethanol and acetone were analyzed by gas chromatography-mass spectrometry. The results showed that there were 109, 70, and 71 components which identified in benzene, ethanol and acetone extracts of olive oil pomade respectively. Many of these components can be resourced in industries of biomedicine, bioenergy, spices, and food additives.

From olive to olive oil: a general approach

“…Larger-scale production takes place in countries in the Mediterranean region, such as Morocco, Spain, Greece, Italy, Turkey, among others, and annual world production varies from 2.6 to 3 million tons. Because olive trees have been cultivated for thousands of years in this region, the consumption of olive oil is highly widespread and has increased around the world due to its beneficial health properties and the highly appreciated sensory characteristics (Melo & Pinheiro, 2012;Li et al, 2020;Ballus et al, 2014).…”

“…Besides, due to the great importance of domestic use, the food industry is increasingly interested in the application of olive oil. Still, the non-food industry uses olive oil as a raw material in the manufacture of anti-aging cosmetics (Kalogianni, Georgiou & Hasanov, 2019;Reboredo-Rodríguez, González-Barreiro, Cancho-Grande & Simal-Gándara, 2014;Li et al, 2020).…”

Numerical investigation of boiling and forced convection heat transfer in inclined porous enclosure using modified enthalpy formulation

“…They are: sub-cooled liquid region, two-phase region and superheated gaseous region. Owing to the generality and the simplicity of the numerical formulation, TPMM of Wang [6] has been most often used for the simulation of two-phase flow within porous media [6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”
