Single-Cell Protein Hydrolysates Market Size - By Source / Organism Type, By Production Substrate / Feedstock, By Application, Growth Forecast, 2025 - 2034

Single-Cell Protein Hydrolysates Market Size

The global single-cell protein hydrolysates market size was valued at USD 288.4 million in 2024. The market is expected to grow from USD 319.3 million in 2025 to USD 721 million in 2034, at a CAGR of 9.5% according to latest report published by Global Market Insights Inc.

• Single Cell Proteins (SCP) Hydrolysates market is one of the key categories in the molecular industry to emerge the attention of the sustainable protein economy. The hydrolysates' functions, digestibility, amino acid bioavailability, and functionality make them useful and derived from bacteria, yeast, fungi and microalgae. They possess a low carbon footprint and their production comes from waste or gas-based feedstocks. These are all the reasons why they are being widely used in Animal feed, Human feeding and Nutraceutical supplements.
   
• The demand for proteins across the globe has risen and due to climate and resource constraints, hydrolysate SCPs are vital in the market especially in aquafeed, clinical nutrition and circular bioeconomy models. They are no longer a niche innovation.
   
• SCP hydrolysates have their benefits and one of them is their efficiency with circular economy models due to their SCP being derived with the use of industrial off-gases, food waste and/or lignocellulosic biomass. This solves land scarcity and mitigates the emissions and food insecurity challenges around the globe.
   
• Regulatory and consumer responses, while still at a distance, are increasingly more positive. To the hydrolysates of SCP, there exist GRAS approvals in some regions (e.g., US, while EU is still pending novel foods status), but the market still lacks comprehensive regulations. Greater downstream processing, nucleic acid removal, and standardization of products are solving previous safety issues.
   

Single-Cell Protein Hydrolysates Market Trends

• Emergence of SCP in Aquafeed Applications: The aquaculture industry is replacing fishmeal with hydrolyzed single-cell proteins due to their sustainability and digestibility. Methanotroph proteins, like Calysta FeedKind, are being used in salmon and shrimp farming where they can supply with their ocean-pollution free, protein-rich feed. The need for sustainable aquafeeds and the demand for low-footprint alternatives drives the use of such proteins in aquaculture.
   
• Transition Toward Circular Biomanufacturing: Trends in sustainability have made SCP, derived from waste gases, biogases. Solar Foods, for example, uses CO2 and hydrogen to create Solein, a protein with virtually no environmental impact. The EU bioeconomy and climate goals are also being pursued by Albion and Deep Branch, who are turning used wooden biomass, off-gases, and captured CO2 into other valuable microbial biomass.
   
• Usage in Protein-Rich Beverages: SCP Hydrolysates serve, until now, only in animal feeding stuff, but are also used in humans as meal replacements, clinical nutrition, and as castor oil protein for easy digestion, targeting the elderly or post-exercise recovery. For example, in protein-rich beverages, yeast hydrolysates serve as umami-rich, flavor enhancer, and protein powders, particularly in the plant-based food sector.
   
• Innovation in Hydrolysis and Functional Peptides: Certain health-affecting bioactivities (e.g. antioxidant, antihypertensive, and anti-inflammatory) can be obtained from gaining specialized peptide profiles. Advancement from both enzymatic and physical hydrolysis is helping to gain and unlock specialized peptide profiles. Targeting and customizing hydrolysates has drawn the attention of DSM-Firmenich and Novozymes. This has drawn attention to the pharmaceutical-grade SCP peptides, focusing on functional food applications, sports nutrition, and on-immunity boosters.
