Forced ripening through the exposure of fruits to controlled environmental and gases conditions is nowadays one of the most assessed food technologies especially for climacteric and exotic products. However, a fine granularity control of the ripening process and consequently of the goods quality is still missing, so that the management of the ripening room is mainly based on qualitative estimations only. Following the modern paradigms of Industry 4.0, this contribution proposes a non- destructive RFID-based system for the automatic evaluation of the live ripening of up to 128 avocados inside the ripening room. The system, coupled with a properly trained automatic classification algorithm, is capable to discriminate the early stage of ripening with an accuracy greater than 85%.
