ABSTRACT Chétoui is the second main olive variety cultivated in north of Tunisia and shows a high capacity adaptation to various pedoclimatic conditions. The aim this work was study changes oil composition such according origin plantation. Thus, olives at same stage maturation were harvested from seven regions country for extraction analysis. Three consecutive crops years 2000, 2001 2002 considered. analytical parameters studied fatty acid composition, triacylglycerol molecular species...
ABSTRACT Characterization of virgin olive oils from two new cultivars obtained through controlled crossings on Meski variety was investigated. These varieties have been selected among a progeny 30 descendants after an evaluation oil fatty acid composition and the content their fruits. The study achieved during crop years 2001/2002 2002/2003. (9D 6H) had improved compared to that Chemlali, dominant Tunisian variety; latter is characterized by low rate oleic high rates linoleic palmitic acids....
The effects of dehulling and milling seeds on the volatiles two Vicia faba L. cultivars were evaluated using headspace-solid phase micro-extraction (HS-SPME) coupled to gas chromatography–mass spectrometry (GC-MS). phenolic constituents antioxidants activities also estimated same kind samples. A total 36 belonging six different chemical classes identified. Among them, 11 compounds determined in emission profile whole bean seeds, 19 from dehulled legume 14 seed flours, 24 flours. difference...
Recent advances in biotechnology have ensured that one of the main olive tree by-products is leaf extract (OLE), a rich source bioactive compounds. The aim this work was to study phenolic composition different OLEs three Tunisian varieties, namely, 'Sayali', 'Tkobri', and 'Neb Jmel'. vitro biodigestibility effect after 'Sayali' OLE addition Californian-style 'Hojiblanca' table olives also studied. This contained molecules such as hydroxytyrosol, tyrosol, oleropeine, Procianidine B1 (PB1),...
In this study, eighteen olive varieties, originating from Spain, France, Italy, Greece and Algeria, maintained at the experimental station of Boughrara (arid region Tunisia) were evaluated for their oil yield fatty acid composition. The analysis variance revealed significant differences among varieties all traits (p < 0.01). Hierarchical Cluster Analysis (HCA) classified into three main groups. first group included a subgroup which is composed seven (Cornezuelo, Verdial de Vélez-Málaga,...
Abstract Fruits from three Tunisian cultivars of Olea europea L. grown in the southeast Tunisia were harvested at maturity stage ripeness and immediately processed with a laboratory mill. There are as yet no data on chemical composition virgin olive oils Tunisia, an area characterized by arid condition growth for trees. Our results showed significant differences analytical parameters examined such fatty acid composition, total phenols o ‐diphenols, content chlorophylls carotenoids,...
A study on the characterization of virgin olive oils from wild olives (Olea europaea L. subsp. oleaster) was conducted in order to define new cultivars which are welladapted Tunisian environment and yield high quality oils. The done during crop years 2003/04, 2004/05 2005/06. main analytical parameters were evaluated: fatty acid compositions, chlorophylls, carotenoids, tocopherols phenolic compounds as well their relationship with oxidative stability. composition all trees tested produced...
ABSTRACT One hundred and fifty accessions belong to six wild olive populations from Tunisia were analyzed using fruit pomological traits oil chemical characteristics. Analysis of variance revealed significant differences among for the main studied parameters, indicating a high degree variability oleasters. Cluster analysis no clear relationships between according their geographical origin. Among screened oleasters, three stand out interesting as compared traditional varieties with oleic low...
The aim of this work was analyzing the use olive leaf extracts (OLE) obtained from two local Tunisian tree cultivars 'Chemlali' and 'Sayali' to reduce acrylamide in Californian-style black olives. phenol profile, antioxidant, antibacterial activity OLE were evaluated. principal phenols found hydroxytyrosol (1809.6 ± 25.3 mg 100 g-1), oleuropein (2662.2 38 g-1) luteolin-7-O-glucoside (438.4 presented higher levels variety. Small differences observed between kinds used; greatest against S....
Chétoui and Chemlali olive fruits were stored at two different temperatures (ambient 5°C) for periods before oil extraction 0, 7, 14, 21 28 days to investigate the effect of postharvest fruit storage on quality. Conventional analyses (acidity, peroxide value, specific extinction coefficient 232 270 nm fatty acid composition) non conventional (pigments, total phenols, oxidative stability radical scavenging capacity) carried out in order evaluate Results showed that ambient temperature led...
In this study, we examined the behavior of six faba bean (Vicia L.) genotypes under salinity conditions at seedling stage.The evaluation was assessed using 21 morphological, physiological, and photosynthetic traits control, moderate, severe conditions.The principal component analysis (PCA) used to identify contrasting in response salt stress characterize important for tolerance.The result PCA showed that displayed different saline most discriminating quantitative characters were related...
