United States Casein And Caseinate Market Trends

Sport/performance nutrition is expected to witness significant growth during the forecast period

• Rising health concerns and memberships across health clubs are primarily driving the sport/performance nutrition segment. From 2009 to 2019, the number of gyms in the United States rose by 39%. However, the segment witnessed a significant decline due to gym closures during the COVID-19 pandemic-induced nationwide lockdown in 2020. Health clubs are among the most popular sales channels for sports supplements. The closure of health clubs had a negative impact on the sales of supplements. In 2020, several gyms like Gold's Gym, Flywheel Sports, Town Sports International, and 24-Hour Fitness declared bankruptcy. Sales of sports nutrition products decreased in 2020, and the segment’s overall Y-o-Y growth rate reduced by 3.37%.
• The importance of leading an active lifestyle is fueling the sports/performance nutrition segment. In 2021, 67% of US consumers aged six and above participated in fitness activities, of which 43.3% of consumers engaged in individual sports, 52.9% in outdoor sports, and 22.1% in team sports. Consumers are becoming more aware of the value of optimal nutrition and healthier lifestyles, all of which positively impact the sports/performance nutrition segment.
• Sports/performance nutrition is the fastest-growing end-user segment in the US whey protein market, of which animal protein accounts for a major share of 91.1% in terms of value. The fitness industry is rapidly increasing the usage of animal protein ingredients, such as whey, collagen, and milk proteins, in nutritional supplements used for muscle or tissue repair after workouts. The rise in the availability of protein supplements, a growth in the number of recreational and lifestyle users of these products, and an increase in health awareness are expected to boost market growth over the forecast period.

Widespread availability of raw cow milk enables the production of skim milk

• The graph depicts the production of skim cow milk in the United States. The availability of raw cow milk enables the production of skim cow milk in the United States. In 2023, 2,408,7 pounds of milk was produced per cow, an increase of 1.30% from 23,777 pounds in 2020. As of 2022, the average number of milk cows in the United States was 9,402 heads. Milk is usually separated through various processes into components and processed into fluid beverage milk or the manufacture of other dairy products.
• Casein is the major protein in cows’ milk and comprises about 80% of the total protein content, of which the rest, some 20%, are whey or serum proteins. Commercial casein is produced from skim milk using one of two main methods: acid precipitation or rennet coagulation. The goal is to remove as much fat, whey proteins, lactose, and minerals as possible through multiple stages of water washing. These impurities can compromise the quality of the casein, so it is important to minimize their presence. Dried, properly produced casein has a relatively good keeping quality and is used mainly in the food and chemical industries. Rennet casein, acid casein, and co-precipitate are major types of casein derived from skim cow milk.
• As the world's largest single-country producer of skim milk powder, this country has tremendous potential in skim cow milk production. US manufacturers continue to boost Y-o-Y production of skim milk to meet changing consumer preferences for low-fat or calorie-deficit diets. SMP contains 5% or less moisture (by weight) and 1.5% or less milkfat (by weight). The difference is that SMP has an adjusted minimum milk protein content of 34%.
