Industrial spice milling and blending line with airborne powder and spice bowls, showing how hidden additives in food supply chains can enter during upstream processing.

A photorealistic, square image showing an industrial spice processing area with stainless hoppers and pneumatic piping in the background. Fine powder hangs in the air, while bowls of colorful spices and powdery materials sit in the foreground. The scene visualizes how hidden additives in food supply chains can be introduced during milling and handling, then carried into finished blends without appearing on consumer labels.
