We screen apples and food to increase the quality in your production chain

The future of agriculture depends on photonic optoelectronic sensors

visual inspection

with spectrometer

Easier quality control with portable spectrometer: Bruises become visible without damaging the fruit

During quality control, random samples of apples from the harvest are inspected, e.g. to determine whether external and internal bruises are present. If the visible bruises on an apple do not cover more than 1 cm2 in total, the apple could still be class I, provided the flesh is not discolored.

Until now, apples had to be peeled in order to be able to check for internal discoloration caused by non-visible bruises. In the infrared spectral range, internal bruises on the apple become visible without cutting it open or damaging it.

Food waste and storage problems with fresh fruit can be actively avoided

Apples with bruises are more difficult to store and spoil more quickly, so it is advantageous to have a method for sorting different apple qualities that counteracts storage problems and food waste. (Assessment of quality in accordance with EU marketing standard Regulation No. 543/2011 Annex I, Part B – Part 1 as at: 01.10.2013, source: Federal Office for Agriculture and Food, Marketing Standards and Conformity Control Department, Bonn)

Ziel ist in Deutschland bis 2030 vermeidbare Lebensmittelabfälle bei Verbrauchern und im Einzelhandel zu halbieren. Auch bei der Nachernte, in der Produktion und bei der Lieferung ist eine Verminderung wichtig. (Bundesanstalt für Landwirtschaft und Ernährung)

Sorting according to quality criteria will be child’s play in future

Optical ripeness measurement technology with infrared spectrometers and artificial intelligence can also be used in large sorting systems with conveyor belts. Algorithms evaluate the condition of the apple and thus help with sorting in real time. State-of-the-art technology makes it quick and easy to decide whether the apple is suitable for short or long-term storage or whether it would be better to mash it.

Fruit and vegetables in sensory focus

Not only apples but also tomatoes, carrots, bananas etc. can be screened using photonic technologies without causing damage.

Even impurities in grain or seeds can be easily detected, as can rotten nuts inside their shells.
