This study was made on two dry dates in Egypt, the first one called seeded dry and the second Bartamouda which is one of the most famous dates in Egypt were used for preparation date powder of snacks with 1, 3 and 5 %, in order to get this product for new snacks from dates. Snack food now include a very wide range of products, including potato and corn chips, alkali- cooked corn tortilla chips, extruded puffed and baked/ fried products, half- products, meat snacks and rice-based snacks. Extruded snacks are products which are easy to consume, tasty, crispy, with thousands of shapes, flavours, textures, and are consumed worldwide. They can be expanded directly or indirectly. Therefore, this study was divided into two parts, the first one related to studying the physical properties, the proximate chemical composition and determination of minerals content of Seeded and Bartamuda date cultivars at tamr stage, then evaluation the effect of date powder addition on the sensory properties of snacks made from corn grits and date powders with concentrations at 1, 3 and 5 %.So, the second part of this research was including study the effect of date powders, added concentration and combination between them on sugars(reducing and non- reducing sugars and total sugars), fats and protein, fiber and total ash, phenols and titratable acidity percentages, phosphorus, potassium,
