A source of sustainable plant protein and the food industry’s ingredient for success

Brewers' Spent Grain

Grain and barley are remarkable natural plant-based assets, packed full of nutrients. Globally, beer brewers produce around 27 million tonnes of Brewers’ Spent Grain (BSG) every year. But it also counts for up to 85% of all their waste. It is time to see BSG as a vital co-product full of protein, fibres and fats for use in food applications. At Duynie Group, we can re-purpose spent grain, upcycle it into totally new food ingredients and at the same time contributing to circular production model for breweries.

The food industry’s ingredient for success

After extraction of the starch and sugars from the malt (barley) for the beer production, the BSG is left as co-product. BSG mainly consists of the fibrous and protein parts of the barley. The fibre and protein come from the husk, aleurone and endosperm layers of barley in BSG from which the brewer has extracted the fermentable starch and sugars. Duynie Group separates the ingredients, stage by stage, making them readily available in three products for the food industry: BSG Native, BSG Fibre and BSG Protein. The products have a high protein content and are rich in fibre. They are very suitable to use in meat replacers, snacks and bakery products amongst others. A major benefit of the locally sourced and produced ingredients is that they are very sustainable. They have a low carbon footprint, less reliance on land and water and lower Scope emissions. A circular approach directly into the food chain.
