| Popis: | The kind Retama belonging to the family of Fabaceae is endemic of the Mediterranean Basin. It characterizes the coastal ecosystems and the desert. In Algeria, three species of the Retama are indicated: Retama monosperma Boiss. Retama raetam Webb and Retama sphaerocarpa L. (Quézel and Santa, 1962).Retama monosperma, object of our study, develops particularly on the littoral dunes of Algeria and presents several interests. To know better this vegetable with the aim of a better valuation adds us a biochemical study of the hémicelluloses. Hémicelluloses has an economic interest mattering in the food and pharmaceutical domain notamment xylose which enters the preparation of alcohols such as the Butanol, the manufacturing of candies without sugars. The extraction of hémicellulos by the protocols gives a yield 14, 33 % of hémicellulose.The qualitative analysis by CCM in shown that hémicelluloses is established by some glucose and by xylose ( glucoxylane ).The pres ence of xyloses in the construction of hémicelluloses incites us to look for protocols of purification of this sugar which gives the xylitol ( C5H12O5) it is the polyol which possesses interesting properties what makes its high value for the pharmaceutical and food industries. It is about one compose which has a similar sweetening power in saccharose , not - cariogene who is already exploit in food industry as ingredient in the chewing gum and the toothpaste . Furthermore he can be use by the obeses persons or the diabetics (Knuuttila and al., 2000) |
