The global sweet protein market is poised for robust growth in the coming decade, fueled by increasing consumer preference for natural and low-calorie sweeteners. The market is projected to generate USD 14.1 million by 2025, expanding to USD 30.8 million by 2035, at a compound annual growth rate (CAGR) of 8.1%. This growth trajectory reflects a strong push towards healthier alternatives to sugar, especially in food and beverage formulations aimed at health-conscious consumers.
Sweet proteins, derived from tropical plants and fruits, such as thaumatin, brazzein, monellin, and miraculin, have gained traction as effective sugar substitutes due to their intense sweetness and negligible caloric value. With increasing scrutiny over artificial sweeteners and their health implications, food manufacturers are increasingly turning to sweet proteins for clean-label product development. This shift is also supported by growing R&D efforts and regulatory approvals for sweet protein use in several countries.
