1. Aesthetics: Doughnuts are often decorated with icing or other toppings to enhance their visual appeal. A well-performing icing coating should have a smooth and even texture, with no cracks or bubbles. This will make the doughnuts more visually appealing to customers and increase their perceived value.
2. Shelf life: A well-performing icing coating can also help extend the shelf life of the doughnut by creating a barrier that prevents moisture loss and extends freshness. This is particularly important for doughnuts that are made in large quantities and need to be stored for several days before being sold.
