Authors : Makhloufi Ahmed .

Abstract

The fruit of date palm (Phoenix dactylifera L.) is an important product in the south of Algeria. Dates played an important role in the economic and social lives of the people. Three Common dates varieties(Tgazza,Tazarzite and Tinnasser) were investigated for biochemical and microbiological composition . Date flesh of all varieties showed high level of total sugars (45 - 65 %) and a small amounts of protein (1.3-2.4%), ash (2.05-2.46%) and fat (0.18-0.31%) on dry matter basis. The mositure content ranged between 8.34 and 12.28 microbiological testing dates show the existence of a total aerobic mesophilic flora and fungi (mold and yeast) and the absence of all fecal coliform bacteria and staphylococcus.
