The total soluble solids play an important role in the fruit maturity process and determine the acceptance of rich nutrients as well as economic benefits in the fruit trade. Thus, development of rapid and nondestructive techniques for evaluating soluble solids content in fruits is important. This review focuses on recent advances in nondestructive techniques for soluble solids contents of fruits including hyperspectral imaging, laser light backscattering imaging, magnetic resonance imaging, X‐ray computed tomography, near‐infrared spectroscopy, and Raman spectroscopy. The advantages and disadvantages of these techniques are compared and discussed, and some viewpoints about future trends are also presented.
