Main Technical Means For Fruit And Vegetable Sorting

‌Near-infrared spectroscopy technology‌: This technology can non-destructively detect the internal quality of fruits and vegetables, such as sugar content, black core, water core, etc. The application of near-infrared spectroscopy technology in fruit and vegetable sorting began in the late 1980s, greatly improving the function of sorting equipment and realizing non-destructive detection of internal quality grades.
‌Machine vision recognition sorting technology‌: Through machine vision recognition technology, fruits and vegetables can be graded according to their appearance color. Although there is a certain correlation between appearance color and internal quality, the misjudgment rate is high and it cannot be applied to some fruits and vegetables such as kiwifruit.
‌Internal quality non-destructive detection technology‌: This technology can accurately detect the internal quality of fruits and vegetables, such as sugar content, black core, water core, etc., without cutting them.
