Fungi in Full Color: Ricky Cassini Reimagines Dye at Michroma
Ricky Cassini, CEO of Michroma and a former logistics professor turned biotech founder, breaks down why replacing synthetic food dyes is harder than it sounds, and why fermentation-based colorants can outperform both petrochemical dyes and many plant-based “natural” extracts. The conversation covers the core technical constraints that matter to food companies (thermal stability, pH stability, coloring power, flavor neutrality, and supply reliability), why fermentation behaves more like manufacturing than farming, and how regulatory shifts are accelerating demand for bio-based reds and whites (including titanium dioxide alternatives). For an audience following the future of materials and biomanufacturing, this episode is a practical look at how industrial fermentation can modernize a legacy supply chain while meeting performance and consumer expectations.
