Brewer's spent grains, a by-product of the brewing industry, were utilized to create innovative dry pasta with enriched protein and fiber content. These newly formulated pasta products showed excellent quality characteristics compared to traditional pasta, highlighting the successful combination of technological aptitude, nutritional/sensorial quality, and sustainability.
Brewer's spent grains are one of the principal by-products of the brewing industry. For protein and fibre content, this by-product represents an interesting raw material to be reused for manufacturing many other products. To maximize the nutritional characteristics of this by-product, in this study, ingredients derived from brewer's spent grains were included in the design of innovative dry pasta. Two brewer's spent grains derivative ingredients, one enriched in proteins and the other in fibre were blended with semolina. Based on the rheological evaluation, the optimal amount of the two ingredients for producing pasta was determined. In particular, pasta responding to the claims High Protein and High Fibre was realized using the formulation enriched with 15% of protein-rich ingredient and the claim High Fibre and Source of proteins using the formulation enriched with 10% of fibre-rich ingredient. The final products were compared to 100% semolina and 100% wholegrain semolina pasta for composition, color, texture, and cooking quality, revealing excellent quality characteristics. The newly formulated pasta represents a successful match of technological aptitude, nutritional/sensorial quality, and sustainability.
