Freeze-dried pineapple is a popular snack, by freezing it and removing all the moisture. The process of freeze-drying involves removing the water from the pineapple and then exposing it to a vacuum environment, which causes the water to evaporate without turning into ice. This creates a crunchy and flavorful snack. Freeze-dried pineapple can be enjoyed on its own, mixed with other fruits or used as a topping for various dishes, adding a burst of tropical flavor to any meal.
