Ingredients giant Döhler has started commercial production in Europe of “SB1,” a high-protein postbiotic ingredient from biomass fermentation startup Superbrewed Food that will support product launches in the US this year.

Döhler Ventures has also invested an undisclosed sum into Superbrewed and will work with the startup to expand production capacity and advance broader commercialization in 2027.

With a neutral taste and color, strong pH and heat stability, and good emulsification properties, SB1—labeled ‘postbiotic cultured protein’ in the US—is a non-GMO bacterium containing 88%+ protein, with a high digestibility score and meaningful levels of B vitamins, iron, and zinc.
