Hendrik Haase

Cocoa beans assessed by algorithms before a human hand touches them. Harvests predicted by AI before they happen. New products developed from data rather than a product developer’s gut feeling. Artificial intelligence is transforming the food industry faster and more profoundly than most companies realize. Hendrik Haase cuts through the hype, maps concrete applications across the entire value chain and delivers a clear-eyed outlook on what this means for businesses in the cocoa and chocolate industry right now.

Hendrik Haase is a communication designer, consultant and food activist. He works at the intersection of the food industry, digitalization and social change, advising companies, associations and institutions that want to understand how their sector is reinventing itself. As the author of “Food Code” and editor of the Digital Food Report 2025 – an annual analysis of the digital transformation in one of Europe’s largest and most demanding food markets – he combines deep industry knowledge with an outsider’s perspective. His keynotes cut through the noise: grounded in data, shaped by practice, and designed to leave audiences with a clearer picture of where their industry is actually heading.

Dr. Yuantong Zeng
Buhler AG

MultiTherm TC of Buhler AG is developed for the determination of crystallization behavior of cocoa butter, cocoa liquor, and chocolate. This instrument is specially designed to minimize the influence of ambient temperature. The cooling temperature is also selected to maximize the expansion of the exothermal reaction of cocoa butter (17.6°C), cocoa liquor (19.0°C), and chocolate mass (20°C). The so-called Buhler Crystallization Index (BCI) is calculated based on the information of the entire cooling curve, including the nucleation and crystal growth portions of the curve. BCI is the new industry standard when it comes to measuring the quality of cocoa butter.
This study investigates the crystallization behavior of cocoa butter in the presence of foreign fats and visualizes it using BCI measurements.

Yuantong Zeng studied food science, specializing in food process engineering, at ETH Zurich, where he conducted research into the shear- and seed-crystallization of chocolate and received his PhD in 2000.

Regulation (EC)3190/2024 bans the use of Bisphenol A (BPA) in certain materials and articles intended to come into contact
with food. Chocolate moulds made from polycarbonate are directly in scope of the regulation. A transition period until January 2028 allows polycarbonate moulds to be produced until January 2028 and sold until January 2029. After that, new moulds must be produced with BPA-free polymers. The presentation summarizes the activities organized by the Association of the German Confectionery Industries e. V. (BDSI) with its Food Chemistry Institute (LCI) to identify and test alternative polymers in industrial chocolate production environment. It furthermore gives an insight into the current regulatory development at European level.

Dr. Johannes Burkard
CHoNova AG / ETH Zürich

(Authors: Johannes Burkard, Frédérique Delahaye, Erich Windhab):
The DetachLog technology, developed at ETH Zürich and CHoNova AG, uses Ultrasound Damping Spectroscopy to reveal chocolate structure formation kinetics from tempering to demolding. Both off-line laboratory and in-line mold-mounted versions monitor ultrasound amplitude damping, local temperature, and 3D acceleration/rotation throughout the molding process. For filled chocolate products, shell formation and filling structuring are reliably tracked across even complex molding-line configurations, with reproducible structure formation patterns observed in both shell forming and filling phases. During rotating shell forming, characteristic sloshing flow patterns are detected and compared with simulations to optimize shell wall uniformity. Vibration is shown to critically extend shell-forming flow duration. Cold-forming and frozen-cone processing reveal analogous but accelerated structuring mechanisms, supported by physics-based modeling.

Johannes Burkard holds a Dr. sc. from ETH Zurich, where his PhD research spanned chocolate additive manufacturing, sensory perception, neuroimaging, and pupillometry.

(Author: Erich Windhab):
Cocoa is a cornerstone agricultural commodity, yet current processing practices leave a significant share of the cocoa fruit underutilized, representing both a missed economic opportunity and an avoidable environmental burden. Cutting-edge innovations developed by ETH Zürich, CHoNova AG and KOA AG can now be employed to convert previously discarded pod components into nutritious, affordable food ingredients, while simultaneously reducing waste and creating new revenue streams for farmers and local processors. Technological insight will be given to the processing of high quality "Whole Fruit Chocolate" and its technofunctional properties, including the tempering, molding, crystallization/solidification and demolding characteristics under authentic processing conditions.
