1. Introduction to Spray Drying
Spray drying is a widely used technique in the food industry due to its ability to efficiently convert liquid food products into dry powders. This method is cost-effective, preserves nutritional and functional properties, and enhances the shelf life of food products. The process involves atomizing a liquid into fine droplets and rapidly drying them using hot air, resulting in uniform, shelf-stable powders.
