Upcycled Ingredients Drive Market Demand

Spent grain is a by-product of brewing and grain processing that contains fiber and other components with potential commercial applications. Processing this material into soluble fiber ingredients can help manufacturers create higher-value products for food, nutraceutical, and animal feed applications.

Food companies are exploring upcycled ingredients as they reformulate products to increase fiber content and improve resource efficiency. Demand for documented ingredient composition and consistent quality is also encouraging producers to invest in extraction and standardization processes.

However, variations in raw material composition, processing costs, and the need to scale food-grade extraction technologies remain challenges for manufacturers.

Wheat Spent Grain and Powder Formats Lead

Wheat spent grain is projected to account for 73% of the market in 2026, supported by its availability and potential for commercial-scale fiber extraction. Animal feed is expected to represent 54% of demand, reflecting established uses for brewery by-products and existing supply channels.

Dry and powder formats are projected to hold a 70% share, offering advantages in storage, transportation, and formulation. Enzymatic hydrolysis is expected to account for 43% of the market as manufacturers seek greater control over fiber composition and ingredient functionality.

Food and beverage manufacturers and nutraceutical producers offer opportunities for suppliers able to provide consistent, well-documented ingredients.

India Leads Country-Level Growth

India is projected to record a CAGR of 11.4% through 2036, supported by demand for fiber-enriched foods and functional ingredients. China follows at 10.8%, with its brewing industry and growing interest in by-product valorization supporting market development.

The United Kingdom is expected to grow at 9.6%, while the United States is projected to register a CAGR of 9.2%. Germany is forecast to expand at 8.9%, supported by its established food processing capabilities and interest in circular resource use.

Analyst Perspective

Shambhu Nath Jha, Principal Consultant at Fact.MR, highlights the importance of extraction quality and standardized fiber composition as the market develops. Suppliers that can demonstrate consistent ingredient specifications and meet food and nutraceutical buyers’ quality requirements may be better positioned to access higher-value applications.

Competitive Landscape

Key companies operating in the spent grain soluble fiber ingredients market include Cargill, Archer Daniels Midland Company, Ingredion, Kerry Group, ReGrained, and EverGrain. Competition is shaped by access to brewery feedstock, extraction technology, ingredient quality, certification, and the ability to maintain reliable supplies for food, nutraceutical, and animal feed manufacturers.
