Chemical composition of second-grade dates (with hard texture) from Tunisian Deglet Nour cultivar was similar to that of commercial dates. Date fiber concentrate (DFC) was extracted and characterized in terms of chemical composition and techno-functional properties. DFC showed interesting functional properties. In fact, it presented high water binding capacities (WBC) and oil binding capacities (OBC) reaching 15.82 g/g and 11.31 g/g, respectively. These Values were higher than those reported for the most fruits and vegetable fiber concentrates. The use of DFC in beef burger formulations improves cooking properties, e.g. increase cooking yield and decrease shrinkage and minimize production Cost Without negatively affecting their sensory properties. Results indicate the potentially functional and economic utility Of Phoenix L. Flesh from dry dates as new source of dietary fiber. [less ▲]

The date by-products of two date palm (Phoenix dactylifera L.) cultivars, Deglet-Nour and Allig, from the Degach region (Tunisia), were analysed for their main chemical composition. Studies were also conducted on the physicochemical properties (colour, water and oil-holding capacity and theological behaviour) of dietary fibre (DF) extracted from date flesh. The following values (on a dry matter basis: DM) were obtained for fleshes of Deglet-Nour and Allig cultivars, respectively: sucrose 52.7% and 13.9%, glucose 13.7% and 29.9%, fructose 12.6% and 29.0%, total dietary fibre 14.4% and 18.4%, protein 2.1% and 3%, ash 2.5% and 2.52%. Insoluble DF, the major fraction of total DF, constituted 9.19-11.7% DM for Deglet-Nour and Allig, respectively. The elaboration of DF concentrates from date fleshes was characterised by an extraction yield of 67%. The chemical composition of these DF concentrates showed high total DF contents (between 88% and 92.4% DM) and low protein and ash contents (8.98-9.12% and 2.0-2.1% DM, respectively). The DF concentrates showed a high water-holding capacity (similar to 15.5 g water/g sample) and oil-holding capacity (similar to 9.7 g oil/g sample),and pseudoplasticity behaviour of their suspensions. Thus, date DF concentrates may not only be an excellent source of DF but an ingredient for the food industry. (c) 2008 Elsevier Ltd. All rights reserved. [less ▲]

Oils extracted from the seeds of two date palm (Phoenix dactylifera L) cultivars, Deglet Nour and Allig, collected from Tunisia, were compared in terms of phenolic, tocopherol and,sterol profiles. These minor components are not only very important for functional properties of oils (oxidation resistance, taste, aroma and color), but could also have many health benefits. Total phenols, considered as the principal source of oil oxidation resistance, ranged from 520.81 for Deglet Nour to 220.32 mg/kg for Allig. High performance liquid chromatography revealed eight identified peaks for which the major component was hydroxytyrosol (10.21%) for Deglet Nour and tyrosol for Allig (8.10%). Total sterol content was 3500 and 3000 mg/kg for Deglet Nour and Allig, respectively. The sterol marker, beta-sitosterol, accounted for 83.31 and 78.66% of total sterols in Deglet Nour and Allig seed oils, respectively. Alpha-tocopherol was the predominant component in both date seed oils (24.97-38.85%). [less ▲]

The seeds of two date palm (Phoenix dactylifera L.) cultivars, Deglet Nour and Allig, from the Degach region-Tunisia, were analysed for their main chemical composition. Studies were also conducted on properties of oil extracted from date pits. The following values (on a dry-weight basis) were obtained for Deglet Nour and Allig cultivars, respectively: protein 5.56 and 5.17%, oil 10.19 and 12.67%, Ash 1.15 and 1.12% and total carbohydrate 83.1 and 81.0%. Gas-liquid chromatography revealed that the major unsaturated fatty acid was oleic acid (41.3-47.7%), while the main saturated fatty acid was lauric acid (17.8%) for the Deglet Nour cultivar and palmitic acid for the Allig cultivar (15.0%). Capric, myristic, myristoleic, palmitoleic, stearic, linoleic and linolenic acids were also found. Thermal profiles of both date seed oils, determined by their DSC melting curves, revealed simple thermograms. Sensorial and physical profiles of Deglet Nour and Allig seed oil were based on studies of the CieLab (L*, a*, b*) colour, oxidative stability, viscosity and microstructure. Results showed that date seed oil could be used in cosmetic, pharmaceutical and food products. (C) 2003 Elsevier Ltd. All rights reserved. [less ▲]

This work is a contribution to give value addition to second grade dates (with hard texture) by the production of enzymatically treated syrup with high commercial value. It was observed that the pulp:water at ratio 1:3 treated with 50 U of pectinase and 5 U of cellulase during 120 min at 50 degrees C gave the highest recovery of total soluble solids (72.37 g of total soluble solids/100 g fresh basis) and the lower turbidity (186.45 NTU) compared with control without enzyme addition (Total soluble solids yields: 66.34 g of total soluble solids/100 g fresh basis and turbidity: 1513 NTU). physico-chemical measurements indicated that carbohydrates were predominant in all date varieties as well as their syrups (similar to 69.59-83.76 g/100 g dry matter in dates and similar to 62.14-74.68 g/100 g fresh weight in syrup). Allig variety was characterised by a high content of reducing sugars content (similar to 77.91 g/100 g dry matter), contrary to Deglet Nour (similar to 23.17 g/100 g dry matter) and Kentichi (similar to 21.3 g/100 g dry matter). The CIE L* a* b* colour values of the enzyme-treated date syrup of Deglet Nour, Allig and Kentichi variety showed lighter colours (L* values ranging from 24.16 to 44) than the control without enzyme (L* values ranging from 0.545 to 17.2). Hedonic evaluation showed that enzyme-treated date syrup was more appreciated by consumers. Microbiological study showed that date syrups were free from aerobes, moulds, coliforms and enterobacteriaceae and were microbiologically stable during five months storage. Results suggested that enzymatic treatment could be used for production of date syrup with high commercial value (C) 2011 Elsevier Ltd. All rights reserved. [less ▲]

St Martin’s church, Angers, is emblematic of the problems raised in pre-12th century history of architecture. In view of the importance of this building, it was necessary to attempt to define its dating and this study particularly focuses on its bell-tower. In addition to the conclusion resulting from the interpretation of written sources and typological criteria positioning the construction of the site at the beginning of the 11th century, not only a significant number of 14C dates were carried out on charcoals from the masonry structures, but also independent dating by archaeomagnetism and thermoluminescence were performed on bricks from the bell-tower. The whole results from these three different methods agree and indicate the lower level of the bell-tower was likely built in the 9th century, disputing evidence to the theory of construction in the 11th century of the church. Presented here are the detailed results obtained from the thermoluminescence (TL) dating analysis. [less ▲]
