3. PROCESSING 3.1 Formula Date-bars are filled biscuits in which the biscuit represents 70% of the bar and the filling with date paste represents the other 30%. The formula is proposed in table 1. Table 1: Formula of Date- bars Part 1: Biscuit (dough) Percentage 1 Wheat flour 37.10 2 Fat (palm oil) 8.75 3 Raising agent 1.40 4 Water 7.00 5 Milk 8.75 6 Sugar (sacharose/fructose/glucose) 7.00 Total dough 70.00 Part 2: Date paste (filling) 1 Fat (palm oil) 1.13 2 Sugar (sacharose/fructose/glucose) 3.00 3 Date 25.63 4 Premix 0.25 Total filling 30.00 Total (p.1+ p.2) 100.00 3.2 Mixing with premix of minerals and vitamins Dosage: premix quantity to add is 835g of premix /100 kg of total filling which represents 30% of the finished product. Mode of mixing: Premix should be added in the date paste filling, as follow: To dilute the premix homogeneously in the added sugar. To mix the added sugar + premix with the shortening in the Z-shape blender. To add 1/3rd of the date paste in the Z-shape blender To mix for 5 10 minutes To add the remaining of date paste in the Z-shape blender To mix for an additional 10 15 minutes. Date-bars manufacturers should send their calculations to the Quality control Unit in Rome for purpose of verification. 3.3 Food safety and risk assessment at manufacturing premises For compliance with Codex standards the processor must be able to demonstrate by principle and practice the adoption, implementation and recording of: Good Manufacturing Practice Hazard Analysis Critical Control Point program 4 / 8
