Description
Microbial-based food coloring utilizes microorganisms to biosynthesize natural pigments for use as sustainable food dyes.
Technical
The process harnesses the metabolic pathways of algae, bacteria, and yeasts to produce phycocyanin, beta‑carotene, and melanin. Extraction involves heat‑stabilized buffer for phycocyanin, anaerobic fermentation for beta‑carotene, and acid hydrolysis for melanin, followed by solvent purification and light protection to preserve chromatic integrity.
