Founded in 2013 as a subsidiary of GenScript, Bestzyme is a global leading functional protein provider dedicated to supporting healthier living through bioscience and precision fermentation. With a steadfast commitment to sustainability, our green biomanufacturing practices minimize environmental footprint and align with modern ESG priorities, enabling food and beverage brands to innovate with planet-friendly ingredients.
Bestzyme introduces Mellia® Brazzein, a nature-sourced sweet protein discovered in the West African Oubli fruit. Guided by our mission to “Make Sweetness Complete,” Mellia® operates as a collaborative taste-solution partner. It harmonizes with existing systems like stevia and monk fruit to eliminate lingering bitterness, round out sweetness curves, and restore clean flavor.
Aligned with modern metabolic health trends and the GLP-1 wellness shift, Mellia® delivers a clean, balanced taste across RTD/RTM beverages, dairy, and confectionery. Already validated in commercial launches across the US, this sweet protein enables brands to reinvent sweetness through nutritional innovation. Backed by FDA GRAS status and a newly inaugurated production line, Bestzyme is the world’s first company with fully integrated global R&D, manufacturing, and commercial capabilities for sweet proteins. This integration delivers cost-in-use advantages, superior batch consistency, and uninterrupted supply, empowering innovators to scale next-generation wellness products with confidence
