Friesland Foods Domo successfully introduced Vivinal Alpha, a whey protein concentrate rich in alpha-lactalbumin for the infant food industry. During the development phase NIZO food research assisted BDI in optimising the processing procedures. By applying the systematic and successful NIZO-SOIR methodology to determine its key aroma components, the flavour characteristics of Vivinal Alpha could be improved.
In close co-operation with the customer technologists, the critical processing steps could be identified and processing procedures were optimised. This resulted in a product with excellent sensory quality.

Subsequently, a shelf-life study for Vivinal Alpha under various storage conditions was started at NIZO food research comprising sensory evaluation and sophisticated analysis for typical flavour components. The results showed that Vivinal Alpha behaved similar to other whey protein concentrates, which demonstrates its applicability in various products.
