Digital gastronomy 2.0: A 15-year transformative journey in culinary-tech evolution and interaction

This paper reviews 15 years of exploration and development in Digital Gastronomy (DG), tracing its progression from foundational frameworks to AI-integrated culinary systems. The journey begins with integrating computational tools like laser cooking, 3D printing, CNC milling, and modular molds, which expand the possibilities of creativity and precision in the kitchen. Building on these technologies, the Meta-Recipe (MR) framework introduces a structured approach to recipe design, allowing chefs to adapt dishes dynamically while maintaining culinary coherence. The concept of “Digital Alchemy” extends this foundation, blending AI-driven methods with traditional healing and sustainable practices to emphasize well-being and environmental consciousness. These advancements culminate in the vision of an AI-augmented kitchen, conceptualized as a collaborative and adaptive space that bridges culinary artistry with algorithmic precision. This research highlights DG's potential as an evolving interdisciplinary field, offering new gastronomy, creativity, and sustainability directions.
