Abstract: Fruit texture is one of the critical indicators determining palatability, storage characteristics, and commercial value. Although conventional texture evaluation methods offer high accuracy, their applications are heavily constrained by destructive sampling, labor-intensive operations, and high operational costs. Recently, non-destructive testing (NDT) technologies leveraging the acoustic, optical, mechanical, and dielectric properties of fruits have advanced rapidly due to their non-destructive nature and high efficiency. Consequently, they have been increasingly implemented in fruit texture evaluation. However, a comprehensive synthesis addressing the specific applicability, distinct advantages, underlying limitations, and optimization pathways of these heterogeneous NDT techniques remains deficient. Therefore, this paper systematically reviews recent breakthroughs in fruit texture assessment using the aforementioned NDT methods. Furthermore, the underlying engineering challenges and bottlenecks encountered in practical applications are thoroughly elucidated. Finally, future research trajectories for fruit texture NDT technologies are prospected, aiming to provide reference for subsequent scholarly investigations.
