In the brewing industry, brewers’ spent grain (BSG) represents the largest by-product, rich in fiber, proteins, and bioactive compounds. While traditionally used as low-value animal feed, the upcycling of BSG through enzymatic processes has unlocked new opportunities in the food, nutraceutical, and bioenergy sectors. At Aurum Process, we are pioneers in providing industrial solutions for the high-value valorization of brewers’ spent grain—with a focus on efficiency, sustainability, and performance.
What is Brewers’ Spent Grain (BSG)?
BSG is the fibrous residue remaining after the extraction of wort in beer production. It accounts for up to 85% of brewery by-products, and it’s available in large quantities year-round. Rich in insoluble fiber, protein, and phenolic compounds, BSG is a promising raw material for sustainable ingredient production.
Enzymatic Hydrolysis: Turning Waste into Value
By applying targeted enzymatic hydrolysis, we break down the complex structures of BSG to release functional compounds such as:
- Prebiotic oligosaccharides
- Bioavailable proteins
- Natural antioxidants
- Fermentable sugars for bioethanol production
This process enables the transformation of BSG into fiber-rich food ingredients, nutraceuticals, and bio-based chemicals, contributing to the circular economy and reducing industrial waste.
