About CHoNova

CHoNova's technology provides real time insights on chocolate crystallization, contraction or demoulding to empower manufacturers to adjust production line parameters, reduce defects, and increase throughput. Chocolate structure formation is per se a complex phenomenon. Getting the right gloss and perfect surface and melting profile has always been challenging and leads to significant time spent on trial and error by manufacturers, together with tons of products being destroyed or reworked. The market situation over the last two years has only accentuated these challenges. The cocoa price has tripled, leading to greater variability in cocoa quality and a push for alternative ingredients. This shifting context only reinforces the need for reliable data to measure chocolate structure formation in real time during production, rather than depending on empirical observations as traditionally done. CHoNova, an ETH Zürich spin-out founded in 2024, addresses this gap with a novel technology based on ultrasound measurement. Sensors embedded in a mold monitor chocolate structure as it cools, crystallizes, contracts, and solidifies, providing 8 robust parameters that directly lead end-product quality. These measurements, analyzed through proprietary software, enable manufacturers to optimize tempering, cooling, and demolding, and adjust recipes with alternative ingredients for the best quality result. Two product formats make the technology versatile: • a laboratory device simulating production conditions, • a production module that delivers live insights during manufacturing.
