For many consumers across global markets, dairy proteins remain most strongly associated with sports nutrition.
Over the past decade, its prominence in formulations for protein shakes, bars, and other performance-oriented products has been reinforced by a steady flow of research highlighting its role in muscle recovery, satiety, and athletic performance. While this has been successful in establishing dairy proteins’ credibility among fitness-minded audiences, it only reflects a portion of its full potential.
The nutritional benefits of dairy proteins – particularly a complete amino acid profile, high digestibility, and positive effects on muscle maintenance – extend well beyond athletes. They are also relevant for older adults seeking to preserve muscle mass, individuals managing metabolic conditions, and the general population aiming to maintain balanced diets. As dietary patterns evolve in rapidly developing regions, this broader applicability becomes increasingly significant.
Southeast Asia, in particular, is experiencing substantial demographic and economic shifts. Rapid urbanisation, rising incomes, and changing lifestyles are coinciding with a growing incidence of metabolic diseases, such as type 2 diabetes and obesity. These trends are creating a pressing need for accessible, high-quality sources of protein to support public health goals.
Organisations such as the U.S. Dairy Export Council (USDEC) are working with food and beverage manufacturers to introduce high-quality dairy ingredients into the region, supporting public health goals while expanding the use of dairy proteins beyond sports nutrition.
For food and beverage manufacturers, the opportunity lies not only in promoting dairy protein through the established lens of sports nutrition, but in developing applications that resonate with local tastes, culinary traditions, and daily eating habits.By integrating high-quality dairy ingredients into products that feel relevant and authentic to consumers in Southeast Asia, manufacturers can help meet rising nutritional needs while broadening the market reach of dairy protein.
Why protein quality matters
Many countries in Southeast Asia face the ‘triple burden’ of undernutrition, overnutrition, and micronutrient deficiency – alongside rising rates of obesity, type 2 diabetes, and, sarcopenia. 1-2 These challenges highlight the importance of improving protein intake not only in quantity but also in quality.
Not all proteins are nutritionally equivalent. Dairy proteins such as whey, milk, and casein consistently score highly on the Digestible Indispensable Amino Acid Score (DIAAS), a gold-standard measure of completeness, digestibility, and bioavailability. As a complete protein, dairy contains all nine essential amino acids the body cannot produce, making it especially valuable for older adults – whose protein requirements are often underestimated – as well as for children, where consistent moderate servings can support healthy growth and development Beyond supporting muscle mass and function, dairy protein can play a role in managing and reducing the risk of metabolic diseases. Emerging research has linked it to improved glycaemic control, better weight management outcomes, and a reduction in blood sugar fluctuations -factors critical in addressing type 2 diabetes and obesity.
Growing knowledge of protein’s role in nutrition
Southeast Asian consumers are becoming increasingly aware of the importance of protein in their daily diet. Consumer research carried out by USDEC found that 64% of surveyed consumers in the region claimed an understanding of protein’s function, with people aged 20-39 years old reporting a stronger grasp of its role.
The same study found a willingness to try protein-added options in food and drink products, as 76% of respondents indicated an interest in such products. Additionally, six out of 10 consumers were prepared to pay more for a protein-added beverage. In providing reasons why, 47% stated that it would be a convenient way to boost protein intake, 43% noted the higher nutritional value, and 43% cited increases in energy and physical performance.
Overall, the dairy products market is experiencing a surge in the region, as the total market is projected to be worth $67bn in 2025 and is expected to grow annually by almost 7%.5 When combined with 62% of consumers reporting that they eat healthy snacks at least once a day, and 59% seeking proteins in their snacks, the picture of the Southeast Asia market is clear; the region is ideal for those looking to develop innovative, nutrient-rich products that align with both the region’s growing health consciousness and its demand for convenient, protein-forward options.
Quality protein, local tastes
Though the Southeast Asia market is receptive to the introduction of protein-added products, this does not mean any product will work. Food and beverage manufacturers will need to be innovative in their choice of products and the quality of the protein added.
USDEC has been involved in the creation of various product concepts to better cater to local tastes and food culture. Among the innovations developed is a reduced-sugar protein mango pudding made with high-quality whey protein isolate.
According to product concept testing conducted by USDEC, more than 90% of consumers surveyed in Thailand, Malaysia and Indonesia expressed a willingness to purchase a high-protein mango pudding.

Other concepts produced were crunchy protein mocha bars, with 89% of surveyed people from Indonesia stating that they would be interested in such a product; and, longan goji berry protein bars/balls, with 57% of respondents from Singapore suggesting that the combination of ingredients accounted for liking the product concept.
Versatility of dairy proteins
The product concepts previously described are possible due to the flexibility of dairy proteins -they are highly functional ingredients for food and beverage applications.
Comprising roughly 80% casein protein and 20% whey protein, milk proteins can be concentrated and dried into a variety of ingredients such as milk protein concentrate (MPC) and milk protein isolate (MPI). Whey protein ingredients include whey protein isolate (WPI) or concentrates (WPC) where the dairy protein in the WPI/WPC is all whey protein.
Unlike many alternative protein sources, these proteins are derived from a soluble liquid without the need for chemical additives or extensive milling, allowing fewer processing steps while maintaining consistent safety and quality.
Beyond their nutritional value, dairy proteins exhibit beneficial functional properties supporting use in formulating a wide variety of culturally relevant foods. Milk proteins are heat-stable, enabling their use in applications ranging from beverages to soups.
Whey proteins have high solubility over a wide pH, making them well-suited for sports beverages and meal replacement options. Their water-binding capacity makes them suitable for high-protein formulations, such as baked goods and ready-to-eat meals.
These characteristics, combined with their digestibility, complete amino acid profile, and metabolic benefits, make dairy proteins particularly advantageous for markets in Southeast Asia, where rising health awareness and demand for convenient, protein-rich products intersect with the need for ingredients that perform reliably across diverse processing conditions.
Building on the functional and nutritional advantages of dairy proteins, USDEC acts as a key resource for food manufacturers across Asia. Its U.S. Center for Dairy Excellence in Singapore provides technical guidance, product innovation support, and application insights that help manufacturers harness the full potential of dairy proteins.
By translating scientific research into practical solutions, USDEC enables companies to develop high-protein, culturally relevant foods and beverages that meet rising consumer demand in the region.
