Gerit Tolborg, CEO and co-founder of Chromologics, joins Karl and Erum to explore how filamentous fungi can replace synthetic and plant-extracted food dyes with a fermentation-derived red pigment called Tellurin. Gerit shares how a PhD discovery in Denmark led to a venture-backed startup producing a tasteless, odorless, and highly vibrant natural color that performs across processed food categories — from cured meats to bakery to dairy. The conversation covers the real economics of bio-based colorants (including the critical concept of cost-in-use versus kilo price), the challenges of scaling downstream processing from a two-liter reactor to industrial CMOs, and how regulatory pathways at the FDA and EU's FSA are evolving to accommodate fermentation-derived ingredients. Gerit also makes a compelling case for fermentation as a tool for decentralizing and de-risking global supply chains — freeing agricultural land from color crop production and building resilience against climate and geopolitical disruption.
