Mesh belt dryers usually dry food through hot air circulation. When drying strawberries, color retention usually depends on the temperature and time of drying and the specific drying method used.

The color in strawberries mainly comes from natural pigments, including anthocyanins, carotenoids, etc. Excessively high temperatures and long drying times may cause the breakdown of these pigments, affecting the color of the strawberries. Mesh belt dryers use lower temperatures and proper ventilation to help maintain the color of strawberries by reducing the risk of pigment breakdown and fading.

However, even with a mesh belt dryer, some minor pigment changes may still occur during the drying process. This is because the heat treatment and moisture loss during the drying process may have some impact on the color of the strawberries. But compared to other drying methods, mesh belt dryers are usually better at maintaining the color and appearance of strawberries.

In general, the mesh belt dryer is a gentler drying method that can help maintain the color of strawberries, but you still need to pay attention to controlling the appropriate temperature and humidity to maximize the pigment and quality of the strawberries.
