Summary

A typical manufacturing process used for instant coffee has been explained to represent the current technologies in freeze-drying of food products. Both academic and industrial challenges were overviewed in this process, especially in preliminary freezing and freeze-drying as well as quality design of freeze-dried products based on the relationship between their physicochemical properties and sensory evaluation scores. Moreover, a novel method has been developed to reduce energy cost in producing freeze-dried products, and to satisfy the food preferences of modern consumers. For further developments in freeze-drying, consumer-oriented perspectives would be more significant, and then fundamental research and practical applications should be increasingly encouraged to investigate the unsolved issues in freeze-drying.
