Over the past 15 years, considerable research activities have been reported on non-destructive texture evaluation of food. This chapter reviews non-destructive sensing techniques, with the emphasis on the latest advances in mechanical and optical techniques, for measuring the texture of solid food. The principles and applications of various non-destructive techniques are described and their merits and shortcomings are discussed. The chapter ends with concluding remarks about research challenges and future directions in non-destructive sensing of food products.
