Vijay Ganugapati’s groundbreaking work in functional milk proteins has doubled the global market and secured future demand for New Zealand milk protein concentrates worldwide.
Ganugapati obtained his PhD in Chemical Engineering from the University of Queensland, Australia before taking up a post doctoral fellowship at Massey University to study Casein protein kinetics. He joined the then New Zealand Dairy Research Institute in Palmerston North in 1992, where he started working on the functionality of Milk Protein Concentrates.
While Milk Protein Concentrates have been commercially available since the 70s, until Ganugapati’s technological innovation, it was not possible to produce soluble milk protein concentrate. Traditional usage of milk protein concentrates was largely limited to cheese applications, and even then it was fraught with the issue of ‘cheese nuggets’; hard lumps which form in cheese as a result of undisolved protein particles. Ganugapati’s breakthrough came in 1998, when he discovered that he could increase the solubility of milk protein by changing its mineral environment without losing the nutritional value of the protein, and most importantly, without adding any chemicals.
Thanks to this pioneering work, milk protein concentrates can now be added to a variety of foods to achieve a number of functions. In fact, Fonterra’s functional milk proteins are now used globally to increase cheese yields; improve the flavour and texture of cultured dairy products; reduce sodium content of processed cheese; increase the protein content of sports beverages to assist muscle recovery; and deliver essential protein nutrition in medical beverages that aid convalescence.
While Ganugapati has been instrumental in developing this game-changing technology, he also credits the work of the wider team of scientists, engineers and technologists at the Fonterra Research and Development Centre and beyond, who have uncovered the multiple benefits of this technology and supported its successful commercialisation. To date, this ability to manipulate the construction of milk proteins is unique, and thanks to Ganugapati, Fonterra and New Zealand remain the leading source of functional milk proteins in the world.
Vijay Ganugapati has published over 30 publications.
