The casein market size has grown strongly in recent years. It will grow from $5.89 billion in 2025 to $6.37 billion in 2026 at a compound annual growth rate (CAGR) of 8.2%. The growth in the historic period can be attributed to dairy industry expansion, food processing growth, protein nutrition awareness, pharmaceutical excipient demand, sports nutrition usage.

The casein market size is expected to see strong growth in the next few years. It will grow to $8.62 billion in 2030 at a compound annual growth rate (CAGR) of 7.8%. The growth in the forecast period can be attributed to functional food demand, clean label trends, pharmaceutical formulation growth, infant nutrition expansion, industrial protein applications. Major trends in the forecast period include rising demand in protein-enriched foods, expansion in pharmaceutical excipients, increased use as functional ingredient, growth in dairy-based nutrition products, adoption in clean label formulations.

The growing demand for cheese is expected to drive the growth of the casein market in the coming years. Cheese is a solid dairy product created by curdling milk and often aged to develop distinctive flavors and textures. Its demand is rising due to increasing consumer preference for protein-rich, flavorful, and convenient foods. Casein, the primary protein in milk, coagulates to form curds, making it a critical component in cheese production. For instance, in 2025, according to the U.S. Department of Agriculture, a US-based government organization, cheese production increased to 22.52 million metric tons in 2024-25, up from 22.3 million metric tons in 2023-24. Therefore, the growing demand for cheese is fueling the growth of the casein market.

Major companies in the casein market are focusing on technological innovations, such as precision fermentation-derived casein, to replicate authentic dairy functionality in plant-based products while addressing sustainability and ethical concerns. Precision fermentation casein is a bioidentical dairy protein produced through microbial fermentation that mirrors the molecular structure and functional properties of traditional casein without using animals. For instance, in October 2024, Those Vegan Cowboys, a Belgium-based food technology company, developed animal-free casein via precision fermentation, a biotechnology that generates dairy-identical proteins without animal involvement. This innovation tackles one of the major challenges in vegan cheese production - replicating the melt and stretch characteristics of traditional dairy cheese. By mimicking the functional properties of milk-derived casein, the product enables plant-based cheeses to achieve authentic texture and performance, enhancing the quality and appeal of vegan dairy alternatives.

In April 2024, Arla Foods Ingredients A/S, a Denmark-based dairy and ingredients company, acquired the Whey Nutrition division of Volac Whey Nutrition Holdings Limited and its subsidiaries, Volac Whey Nutrition Limited and Volac Renewable Energy Limited, for an undisclosed amount. Through this acquisition, Arla Foods Ingredients A/S aims to establish the Felinfach site in Wales as a global production hub, broaden its product portfolio in the performance, health, and food sectors, and leverage Volac’s expertise in whey-based nutrition to accelerate growth in international sports nutrition markets. Volac Whey Nutrition Holdings Limited is a UK-based company specializing in whey processing for sports, food, and animal nutrition applications.

Tariffs have influenced the casein market by increasing the cost of importing dairy raw materials, milk proteins, and food-grade processing inputs. Food and beverage, pharmaceutical, and cosmetic applications are most affected, particularly in Asia-Pacific and Europe due to reliance on international dairy trade. Industrial and nutritional grade casein segments face margin pressure. However, tariffs are encouraging domestic milk processing and local protein extraction, strengthening regional supply chains.

Casein is a protein primarily found in milk and dairy products, accounting for about 80% of the protein content in cow’s milk. It is characterized by its slow digestion rate, providing a steady and prolonged release of amino acids into the bloodstream, making it a popular ingredient in protein supplements, particularly for nighttime use.

The main types of casein are acid casein and rennet casein. Acid casein is produced by adding acid to skim milk, which causes the casein proteins to coagulate and separate from the liquid at a specific pH. Casein can be sourced from cow’s milk, goat’s milk, and sheep’s milk, and serves functional roles as an emulsifying agent, texturizing agent, foaming agent, and thickening agent. It is widely applied across industries such as food and beverages, pharmaceuticals, cosmetics, industrial applications, and others.
