Abstract

A non-destructive method for determining the maturity and quality of fleshy fruit such as blueberries comprises irradiating the fruit with electromagnetic radiation comprising at least one wavelength capable of causing the chlorophyll of the fruit to fluoresce, passing the signal returning from the fruit through a filter capable of filtering out at least one wavelength used for exciting the chlorophyll of the fruit to obtain a chlorophyll fluorescence signal and measuring the signal. The method is based on determining the quantity of fluorescence by chlorophyll of the fruit. The fruit can be further sorted on the basis of the measured chlorophyll fluorescence signal. Because the intensity of the chlorophyll fluorescence is directly related to the quantity of chlorophyll, it is possible to sort fruit and berries as to the stage of ripening and quality. The irradiated electromagnetic radiation preferably has a wavelength of 400-700 nm and the fluorescence is measured at 600-800 nm.
