High-fat foods, such as butter and oils, and high-sugar foods, like honey or syrup, cannot be freeze-dried because they do not contain enough moisture. Alcoholic beverages and carbonated drinks are also unsuitable due to their volatile nature. Additionally, foods with a high moisture content, like watermelon, can be challenging to freeze-dry effectively. Instead, focus on low-fat, low-sugar foods for successful freeze-drying, like fruits, vegetables, and lean meats, which preserve well and maintain their nutritional value over time.
