Arla Foods Ingredients has received a 2014 IFT Food Expo Innovation Award for a unique process solution that enables Greek yogurt producers to make money from their acid whey waste stream by converting it into added-value dairy products. Acid whey has been put into the spotlight recently as a result of the booming popularity of Greek yogurt. For every 100kg of milk used to make Greek yogurt, only 33kg ends up used in the final product. The remaining two-thirds is acid whey, a by-product that must be dealt with by the processor. Many Greek yogurt producers simply dispose of acid whey in their waste stream, which attracts unwelcome overheads and zero income and controversy on environmental grounds.
