Determining quality of fruit and berries and apparatus for sorting
- Title:
Method for determining the quality of fruit and berries and apparatus for sorting fruit and berries
- Publication number:
WO0002036
- Description:
The invention relates to a method for determining the quality of fruit and berries by irradiating fruit and berries with electromagnetic radiation. The chlorophyll present in the fruit or berries shows prompt fluorescence as a result of this irradiation. The present invention also relates to an apparatus for sorting fruit and berries, at least consisting of a feeder part for the fruit and berries, a part for irradiating the fruit and berries with electromagnetic radiation and a part for measuring the chlorophyll fluorescence signal returning from the fruit and berries, and a separation part which operates on the basis of the chlorophyll fluorescence signal returning from the fruit and berries. By chlorophyll all appearances of the chlorophyll molecule are meant, such as the chlorophyll known as leaf green, protochlorophyll, etc.
The method of the invention is particularly suitable for determining the quality of blue berries and can especially be used with frozen berries.
