Get ready to dive into the world of freeze-drying plant-based foods! We all know that freeze-drying is the most superior method of dehydration methods, preserving the structure, shape, and nutrients of products with minimal volume reduction. However, with four to ten times more energy requirements than regular hot air drying, making it the most expensive dehydration process. However, as it becomes more readily available, those costs are starting to make this process more popular and affordable. Traditionally, it was reserved for space shuttle snacks or military meals, but with the growing demand for natural and organic foods, freeze-dried plant-based foods are taking over the market.
Plant-based foods are crucial components of a healthy diet and can help prevent diseases like cancer and cardiovascular diseases. The World Health Organization and Food and Agriculture Organization recommend a daily minimum consumption of 400g of fruits and vegetables to minimize chronic diseases and micronutrient deficiencies. However, fresh produce is not always available, and long-term storage can be difficult. Drying plant-based foods can allow for long-term consumption and easier handling, transportation, and storage.
When food is dried, its quality undergoes changes that can be classified into three categories: physical, chemical, and nutritional. Physical changes occur when food is dried due to the loss of water content. This results in changes in texture, color, and shape. For example, fruits and vegetables become shriveled and brittle after drying. Chemical changes happen due to the breakdown of nutrients during the drying process. This can result in changes in flavor, aroma, and nutritional value. Some vitamins and minerals are lost during drying, while others may become more concentrated. Nutritional changes occur when the dried food becomes more concentrated in calories, protein, and other nutrients. This makes dried food an excellent source of energy, especially for hikers, campers, and other outdoor enthusiasts. Overall, drying food is a great way to preserve it for longer periods while maintaining its nutritional value.
Freeze-drying is the preferred technique for dehydrating fruits and vegetables while preserving the optimal biochemistry of the final product. Despite being a costly and time-intensive process, it is the most favored method due to its exceptional capacity to maintain food quality when compared to other drying methods.
