VALORISATION OF DATES (CULTIVAR 'GHARS') BY TECHNOLOGICAL PROCESS

The Algerian phoeniculture orchard is characterized by its extraordinary genetic diversity. The cultivar ‘Deglet Nour’ takes the front to the detriment of other cultivars, called “common”. The economic importance of the latter, whose number exceeds 870 (Hanachi and Khitri, 1992) is reduced. They are marginalized or ignored. The soft dates, such as those of the cultivar ‘Ghars’ are produced in relatively larger quantity in the region of Ouargla. Highly valued by local people, they are unknown to the rest of the country. Offering no guarantee of conservation, they are not the subject of marketing in the internal market and even less on the external market. In parallel, there are no factories nationwide, to develop them through their transformation. This study is in this context and aims to find outlets for these cultivars, generally low commercial value, with the main objective, the conservation of genetic diversity, a sine qua non for the preservation of phoenicultural patrimony. It is the development of products with high added value: the juice and syrup from ‘Ghars’ dates. Traditional practices have been the source of our investigations. Processing techniques adopted are relatively simple and the products have the advantage of interesting characteristics both on the organoleptic and nutritional plan as the diet plan. The study shows that the glucidic composition of these bioproducts is comparable to that of isoméroses syrups or (high fructose corn syrup: HFCS) from the starch industry and destined for diabetic and/or obese people.
