Non-destructive Fruit Quality Control Using Radioelectronics: a Review

Abstract

this review presents non-destructive methods for determining the quality characteristics of various fruits and vegetables, and provides comparison tables for which fruit/vegetable is most often measured, which fruit/vegetable is most popular among researchers, and by which characteristics researchers correlate their results with a particular quality characteristic of a fruit or vegetable. All investigated methods attempt to find and determine how the physical parameters of a fruit or vegetable correlate with its quality, for example, maturity or color. Non-destructive fruits testing methods have their strengths and weaknesses, e.g., such as safety problems in X-rays or operational limitations in ultrasound. The method of optical properties measurement can detect damaged surface of the fruit but cannot detect its internal quality. Due to the high cost, NIR and IR are not often used on an industrial scale, and a specially prepared closed system is required to use visible and acoustic methods.
