Olive Oils from Fruits Infected with Different Anthracnose Pathogens Show Sensory Defects Earlier Than Chemical Degradation

Sensory and Chemical Analyses of Monovarietal Olive Oils from Lake Garda (Northern Italy)

The qualitative description of an olive oil should be based not only on chemical and physical analyses but also on sensory evaluation. The present study was designed to evaluate by sensory analysis the monovarietal oils from olive accessions in a germplasm collection in northern Italy’s Lake Garda area. Relationships of chemical and sensory evaluation were studied by correlation and multiple re...

Sensory Defects of Virgin Olive Oil from a Microbiological Perspective

Virgin olive oil is the juice from the olive drupe, a produce that usually features high 6 quality. However, virgin olive oils produced in different regions of the world suffer from 7 defects, most of them of sensory nature. The largest amount of olive oil in which some 8 organoleptic defect is present matches to the Virgin Olive Oil (VOO) class. The causes 9 leading to sensory defects in virgi...

Saturated hydrocarbon content in olive fruits and crude olive pomace oils.

Olive fruits contain an n-alkane series of saturated hydrocarbons mainly in the pulp. Lower amounts of a complex mixture of paraffins, unresolved by gas chromatography (UCM--unresolved complex mixture), have been found in cuticle, stone (woody shell and seed), olive leaves, and talc used as an aid to olive oil extraction. The amounts of both kinds of hydrocarbons are related to the olive cultiv...

Factors that influence color degradation in extra virgin olive oils

In the last twenty years the consumption of olive oil has gone from being located in the Mediterranean Area to expanding around the world and considering today the olive oil as a product of global consumption . Doubtless, one of the pillars that has allowed the rapid expansion of its consumption is its rich composition in polyphenols, sterols and antioxidants that confer numerous benefits for h...
