Dairy Foods: processors combine higher protein, less sugar and cleaner labels
Protein remains a major influence on dairy development. The International Food Information Council’s 2026 Food & Health Survey, cited in the report, found that 70% of Americans actively seek to include protein in their diets. A high-protein diet was followed by 27%, compared with 4% in 2018; 22% followed a low-sugar diet. The proportion describing their eating pattern as clean eating reached 17%, against 13% in 2025. Manufacturers are considering protein enrichment for cottage cheese, sour cream and creamers, extending development beyond yogurt and ready-to-drink protein beverages. These projects bring nutritional fortification into familiar dairy categories while adding requirements for maintaining their established sensory characteristics.
Research from the National Frozen & Refrigerated Foods Association also identified changes in purchases among people currently using GLP-1 medications. Of those surveyed, 52% said they were buying more protein-rich dairy foods, while 48% reported increased purchases of single-serving or portion-controlled products. The report identifies protein concentration, convenient portions and digestive-health positioning as areas for product development, with nutritional claims requiring scientific support and compliance with applicable regulation. Manufacturers are also working to incorporate additional fibre. Across these projects, the report describes a need to coordinate nutritional specifications with product consistency, shelf life and manufacturing costs, rather than developing each attribute separately.
Sugar reduction presents several functional problems because sugar contributes to the physical structure of dairy foods as well as their sweetness. Changes in sugar content can alter yogurt’s creaminess, the thickness and stability of drinks, and the ease with which ice cream can be scooped. They can also affect melting, ice-crystal development and flavour balance. Suppliers are using blends of sweetening ingredients, soluble fibre, starches and hydrocolloids to recover these properties. One approach combines stevia with allulose or erythritol to provide bulk, together with soluble fibre to support mouthfeel. Formulators use these combinations to retain the sensory characteristics of the original recipe while lowering its sugar content.
Demand for simpler labels is affecting the choice of ingredients used to provide texture and stability. Consumers increasingly favour familiar ingredient names, shorter lists and fewer artificial additives, although the meaning of a clean label varies between markets and product categories. Processors are assessing starches, fibres and other ingredients with recognisable label descriptions for their functional performance. Filtration and other processing methods can also reduce dependence on some stabilisers. The report notes that removing an ingredient without accounting for its role can damage product quality. Ingredient selection therefore involves both the wording consumers see on the package and the technical contribution of each component during processing and storage.
Higher protein concentrations introduce a separate set of sensory and stability difficulties. Dairy proteins can produce bitter or astringent flavours and a chalk-like sensation, particularly when used at higher levels. In drinks, they can aggregate, settle out or form gels, while viscosity may become inconsistent and stability may deteriorate during storage. Suppliers offer functional dairy proteins alongside starches, hydrocolloids and formulation systems to address these problems. Partial hydrolysis of dairy proteins can help modify beverage texture, and chelating salts can limit interactions between proteins that contribute to aggregation. Maintaining protein stability is particularly difficult in acidified dairy drinks, where developers must account for the behaviour of proteins in an acidic formulation.
Culture selection is another part of developing protein-enriched yogurt with less sugar. Changes in those two ingredients can affect fermentation, acid development, thickness, firmness and the separation of whey. Novonesis says cultures must be selected with the intended protein and sugar concentrations, flavour, texture and shelf-life specifications in mind. In a customer example described in the report, a spoonable yogurt formulated with high protein and low sugar became excessively acidic and developed a chalky mouthfeel during storage. Switching the culture system improved creaminess and viscosity, limited whey separation and helped control acidity, while retaining the desired clean-label formulation. The application involved coordinating culture choice with the ingredients and processing conditions.
Availability and cost are also influencing protein selection. The report describes constrained supplies of whey protein isolate for acidified beverages, leading some developers to examine acidified whey protein concentrates as an alternative. These ingredients have different sensory and functional properties and are being considered as manufacturers manage sourcing and formulation costs. Suppliers are increasingly offering coordinated formulation packages that bring together proteins, cultures, sweeteners, fibres and stabilising ingredients, rather than selling ingredients individually. Their work also incorporates processing technology as manufacturers seek to meet requirements for nutritional content, digestive-health positioning, recognisable ingredients, consistent flavour and texture, dependable shelf life and competitive production costs.
