A dose-response relationship was not observed in olive fruit fly, Bactrocera oleae (Gmelin), larvae exposed to acetic acid concentrations (0-2.5%) used in commercial brine solutions to cure olives. Immersion in a 1% acetic acid brine solution impeded emergence of the immature stages. A 1-wk exposure of olives infested with olive fruit fly larvae to low-temperature storage as a postharvest treat...

The aim of this study was to evaluate the survival of Salmonella, Escherichia coli O157:H7, Listeria monocytogenes, and Staphylococcus aureus on natural black olives during aerobic storage without brine and to conclude about the safety of this fermented food. Fermented black olives (pH 3.95; NaCl 6.02%) were artificially inoculated with 4 strains of Salmonella enterica ser. Enteritidis, 4 strai...

BACKGROUND AND AIMS The olive (Olea europaea subsp. europaea) was domesticated in the Mediterranean area but its wild relatives are distributed over three continents, from the Mediterranean basin to South Africa and south-western Asia. Recent studies suggested that this crop originated in the Levant while a secondary diversification occurred in most westward areas. A possible contribution of th...

This work focuses on the persistence of the putative probiotic bacteria Lactobacillus pentosus TOMC-LAB2 on green Spanish-style Manzanilla olives according to different packaging conditions and storage temperatures. The lactic acid bacteria population decreased with time but the highest survival counts (and lowest yeasts) at the end of storage (8 months) were observed in plastic pouches under n...

Storage at 3 and 18 °C of 'Arbequina' olives (Olea europaea L.) cultivated in hedgerows and harvested manually or mechanically (wine grape harvester) was tested. Fruit characteristics and oil quality were monitored. Mechanical harvesting caused internal fruit damage that induced its rapid softening and decay, but also facilitated obtaining higher amounts of oil, which suffered a rapid deteriora...

Olives debittering, organoleptic quality and safety can be improved with yeasts lactic acid bacteria (LABs) selected strain starters, that allow for better fermentation control respect to natural fermentation. Two killer (Wickerhamomyces anomalus Saccharomyces cerevisiae) Lactobacillus plantarum strains were tested olive (cv. Leccino) compare different starter combinations strategies; the aim w...

Table olives are the most widely consumed fermented food in the Mediterranean countries. Peculiar processing technologies are used to process olives, which are aimed at the debittering of the fruits and improvement of their sensory characteristics, ensuring safety of consumption at the same time. Processors demand for novel techniques to improve industrial performances, while consumers’ attenti...

abstract: olives belong to the family of olea europaea l. is a popular fruit tree. the fruit and the oil extracted from it is consumed worldwide particularly in the mediterranean regions. in this study changes in the fatty acid composition of the oil extracted from olive fruit during the course of maturation is investigated. this work is concerned with the best harvesting point when oleic acid ...

The olive tree is a member of the Oleaceae family, which contains the genera Fraxinus, Forsythia, Forestiera, Ligustrum and Syringa, as well as the genus Olea. Commercial olives are products of the Olea europaea L. species. There are roughly 20 species of Olea found throughout tropical and subtropical regions of the world, but only O. europaea L. produces edible fruit. The fruit of olive trees ...

Green fermented olives cv. Halkidiki were subjected to different treatments of high hydrostatic pressure (HHP) processing (400, 450, and 500 MPa for 15 or 30 min). Total viable counts, lactic acid bacteria and yeasts/moulds, and the physicochemical characteristics of the product (pH, colour, and firmness) were monitored right after the treatment and after 7 days of storage at 20(°)C to allow fo...
