Upcycled Brewing Protein Ingredients

Duynie Transforms Brewers' Spent Grain into Protein

Upcycled brewing protein ingredients are creating new opportunities for food production as Duynie develops DuyGrain, a concentrated protein source made from brewers' spent grain. The company uses a patented separation process to transform this beer production byproduct into an ingredient suitable for human and pet food applications, offering an alternative to conventional protein sources.

Traditional brewers' spent grain contains approximately 20% protein and 70% fiber. DuyGrain increases protein concentration to more than 50% while reducing fiber content to 25%. Its consistent quality makes it suitable for applications such as meat alternatives and bakery products, where reliable ingredient performance is important.

For Duynie, the process creates commercial opportunities by turning brewing residues into higher-value food ingredients. Food manufacturers could benefit from additional protein options with a lower environmental impact than conventional meat and dairy proteins, supporting more resource-efficient production.
