Arla Foods Ingredients harnesses upcycling potential of acid whey

Arla Foods Ingredients (AFI) is showcasing how acid whey can be upcycled into a valuable ingredient for high-protein dairy products. The new "Upcycle Your Whey to Value" concept addresses a sustainability issue in the dairy industry, where two-thirds of the milk used for Greek yogurt and other strained dairy products ends up as waste. Disposing of acid whey, a main by-product, is not only costly but also poses environmental risks. However, it is nutrient-rich and, with the right expertise, can be converted into a nutritious ingredient, creating opportunities for innovative food and beverage products.
AFI has developed three new ambient dairy concepts that highlight acid whey’s potential for upcycled products:
An 8% protein drinking yogurt and An 8% protein creamy dessert with pineapple and coconut flavors.
An 8% protein beverage with a strawberry flavor.
In each of these recipes, acid whey makes up 50% to 73% of the product, combined with ingredients from the Nutrilac® ProteinBoost range of microparticulated whey proteins. The recipes deliver a mild dairy taste and a creamy mouthfeel, while also offering good viscosity and stability over their shelf life. They are suitable for standard dairy processing lines, making them accessible for manufacturers.
The concept supports a growing market demand, as consumers become increasingly concerned with climate change and waste. More than 80% of dairy consumers are aware of sustainability issues, and 20% are actively changing their buying habits.
Claus Andersen, Senior Dairy Category Manager at AFI, said: “Upcycled side-streams can help brands reduce waste and attract climate-conscious consumers. Acid whey, combined with the right ingredients, allows for indulgent and nutritious products, keeping milk’s benefits in the food chain."
AFI will present the "Upcycle Your Whey to Value" concept at Stand R-K3, also showcasing solutions for high-protein cheese and overcoming technical challenges in dairy production
