• Packaging and Storage: The milk is packaged in sterilized, food-grade containers, such as cartons or plastic bottles. It is then refrigerated at below 4°C until distribution to prevent spoilage.

• Inventory Management: A proper requisition process ensures that food service operations maintain accurate inventory levels. This avoids overstocking or understocking, both of which can negatively impact the efficiency of the kitchen.
• Cost Control: Food material requisition helps control costs by ensuring that only the necessary quantities of ingredients are ordered, reducing waste and minimizing excess spending.
• Quality Assurance: Through the requisition process, the quality of food materials is monitored by specifying the required standards. This ensures that high-quality ingredients are ordered and used in meal preparation.
• Menu Planning: Requisitioning ensures that all ingredients are available when needed, aligning with the menu offerings. Proper planning avoids last-minute substitutions that could compromise the quality of the dishes.
• Supplier Relationships: Regular requisitioning helps build strong relationships with suppliers, ensuring timely and accurate deliveries. Reliable suppliers contribute to the smooth operation of food service businesses.
• Operational Efficiency: Streamlining the requisition process leads to greater efficiency in the kitchen by ensuring that ingredients are available when required, preventing delays in food preparation and service.
