Valuable Nutrients and Functional Bioactives in Different Parts of Olive (Olea europaea L.)—A Review
The Olive tree (Olea europaea L.), a native of the Mediterranean basin and parts of Asia, is now widely cultivated in many other parts of the world for production of olive oil and table olives. Olive is a rich source of valuable nutrients and bioactives of medicinal and therapeutic interest. Olive fruit contains appreciable concentration, 1-3% of fresh pulp weight, of hydrophilic (phenolic acid...
The storage life of mushrooms is less than the other vegetables due mainly to high water contents and a porous and thin epidermal structure. This research was aimed at obtaining a suitable compost combination and an optimal condition of maintenance for increase the storage life of button mushroom. The experimental factors consisted of two maintenance temperatures (4°C and 25°C), two types of pa...
Fruit ripening stage at harvesting time is potentially a major contributor to olive oil yield and quality. Therefore, one of the main causes for low olive oil quality, at least in northern Iran, is harvesting fruits at improper time. In this study, effect of fruit harvest time on oil yield and quality of four olive cultivars, Zard, Rowghany, Arbequina and Coratina was investigated at Roudbar re...
This study focused on the characterization of olive oil produced in the Kairouan area (center of Tunisia) in order to install Protected Geographical Indication (PGI). Thus, chlorophylls, carotenoids, phenols and tocopherols contents, fatty acid composition, quality parameters and organoleptic profile were determined on 90 samples of extra virgin olive oil extracted from two different varieties ...
A pneumatic olive harvester was developed and evaluated in this study. The components of the machine were limb clamp, vibrating unit, control elements, main tube, air-pressured hoses, valve, power source. measurements that related to development fruit damage, some physical mechanical properties olives fruit-stem system. results demonstrated effectiveness harvest fruits. appropriateness by crite...
Production of California table olives has declined significantly in recent years due to hand harvesting costs, often over 60% gross return. Mechanical could sharply decrease harvest increasing economic viability. harvester efficiency is a combination the percentage total fruit on tree removed by harvester, and time required do so. A comparison between an experimental canopy contact shaker comme...
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...
Olive breeding programmes are focused on selecting for traits as short juvenile period, plant architecture suited for mechanical harvest, or oil characteristics, including fatty acid composition, phenolic, and volatile compounds to suit new markets. Understanding the molecular basis of these characteristics and improving the efficiency of such breeding programmes require the development of geno...
In the present study, bio-meteorological models for predicting olive-crop production in the southern Iberian Peninsula were developed. These covered a 16-year period: 1994-2009. The forecasting models were constructed using the partial least-squares regression method, taking the annual olive yield as the dependent variable, and both aerobiological and meteorological parameters as the independen...
The Mediterranean diet appears to be associated with a reduced risk of several chronic diseases including cancer and cardiovascular and Alzheimer's diseases. Olive products (mainly olive oil and table olives) are important components of the Mediterranean diet. Olives contain a range of phenolic compounds; these natural antioxidants may contribute to the prevention of these chronic conditions. C...
