Day 3 we learned about disorders, diseases, insects and ways to use modified atmosphere and ethylene blocking to extend storage of plant products. We ended the lecture program with pitches and Q&A on various new technologies within the postharvest domain that will likely to enter commercial practice within 5 years: non-destructive quality measurements by Aneesh Chauhan; improved automation, robotisation and “deep learning” technologies for sorting and objective quality control by Rick vd Zedde; use of LED-light treatments before and after harvest to improve product quality by Ernst Woltering; and use of Big Data and ”Bayesian networks” for product quality prediction by Eelke Westra. After that all participants received their certificate.

Day 4 we visited cool storage facility NedCool, tomato packer and distributor Prominent and fruit importer and ripener Natures Pride. We had a great time, everybody was very interested and asked us a lot of questions. We hope to again host a group of such enthousiast participants in 2019 for the 6th edition!
