About us

The DIAAS calculator website is an initiative of Avebe, the global market leader in potato starch and potato protein, and their lead nutritionist Dr. Bart Pennings. The goal of the website is to provide a quick and easy tool to calculate the DIAAS of dietary protein blends, as well as educating people about protein quality, and DIAAS in particular, and creating an up-to-date and scientifically independent data base of DIAAS values of dietary proteins or protein sources. The latter is being achieved by support and endorsement from scientists and researchers working in the field of protein quality, either within food industry, academia or non-profit organizations.

Avebe is a farmer-owned company from Europe focusing exclusively on processing non-GMO potatoes into top notch ingredients for the global food industry. Being farmer-owned, Avebe controls the entire supply chain from potato field to food ingredient, allowing a clear and transparent story for consumers. At nearly 100 years in business, Avebe has become the world’s largest producer of potato starch and potato protein by working continuously on innovative solutions for its customers.
