Global Milk Whey Powder Market Will Grow 5% Through 2035
The IndexBox outlook places the market index for milk whey powder at about 155 in 2035, compared with 100 in 2025. Its projected annual growth range is 4–6%, with the central scenario set at 5%. The report links demand to applications including infant, sports and clinical nutrition, as well as functional foods.
Higher-protein ingredients are gaining market value. Whey protein isolates and high-protein concentrates account for an estimated 30–35% of total market value and are expanding by roughly 7–9% a year. Their amino-acid composition and functional properties support their use in fortified products. The report identifies WPC grades from 34 to 80 and WPI grades above 90 as the main sources of projected value growth, while conventional sweet whey powder is expected to increase more moderately.
Infant formula is estimated to represent 28% of global demand, the largest share assigned to any single end-use category. Whey ingredients are used to adjust protein levels and support digestibility in formula products. The segment is forecast to grow by about 3–5% annually through 2035, with demand for specialised products, including formulas for allergic and preterm infants, supporting premium whey fractions. China, India and Southeast Asia are identified as important markets as formula use and premium products expand.
Sports nutrition is projected to be the fastest-growing major application, at 7–9% a year through 2035. Concentrates and isolates are incorporated into supplements, ready-to-drink products, protein bars and fortified snacks. North America and Europe remain established markets, while China and India are among the rapidly expanding markets in Asia-Pacific. Bakery and confectionery account for about 20% of global demand, with whey powder used in breads, cakes, biscuits and chocolate products for texture, flavour, browning and dairy solids. This category is expected to grow by 2–4% annually.
Animal feed represents an estimated 18% of demand and uses whey powder as a source of digestible protein and lactose, particularly in pig and poultry feed. The report projects annual growth of around 3–4% for this application. Other food and beverage uses make up the remaining 12%, covering dairy products, ice cream, processed meat, drinks and functional nutrition products.
Asia-Pacific accounts for approximately 45% of global demand and is forecast to grow by about 5–7% a year. Its market includes substantial imports and demand for infant formula, sports nutrition, bakery products and other protein-fortified foods. North America represents roughly 20% of the market and remains a major production and export centre. Europe accounts for about 18% and is also a major producer and exporter. Latin America has an estimated 10% share, and the Middle East and Africa about 7%.
Supply is concentrated in the European Union, the United States and New Zealand, which together account for an estimated 70–80% of intercontinental shipments. The five largest dairy cooperatives and processors are estimated to control 45–55% of production capacity. Farm-gate milk prices can vary by 15–25% in a year, affecting whey feedstock costs and processor margins. Tariffs, anti-dumping measures and changes to maximum residue limits are cited as factors affecting international trade, while pea, soy and mycoprotein products compete with whey ingredients.
Membrane fractionation and spray-drying technologies are being developed for higher-value whey products. The report also identifies clean-label and non-GMO certification as increasingly important in developed markets. These trends are associated with investment in equipment for more specialised whey fractions and consistent product quality.
