What You Need to Know
Rehydration involves the absorption of water by the food's cellular structure, influenced by factors such as temperature, water activity, and rehydration promoters. The rate of rehydration can be affected by these factors, and techniques like soaking, steaming, or blanching can be used. High-temperature rehydration can lead to undesirable compounds and texture changes due to the Maillard reaction and starch gelatinization.
