Driver: Rising Global Protein Demand for Food, Feed, and Supplements

Global demand for dietary protein has been increasing steadily over recent decades. According to the Food and Agriculture Organization’s (FAO) global food balance data, per capita protein availability worldwide rose by about one-third since the 1960s, from around 60 g/day to over 90 g/day today, reflecting higher consumption of both plant and animal protein sources. This upward trend is linked with population growth, urbanization, and rising incomes, which increase demand for animal protein such as meat, dairy, and seafood. FAO-OECD projections indicate global animal protein demand will continue to grow over the next decade, with meat consumption increasing by nearly 48 million tonnes through 2034.

Single-cell proteins (SCPs), microbial biomass from bacteria, yeasts, fungi, and algae, are increasingly recognized as sustainable protein sources that can help meet this expanding protein requirement. SCPs can be produced efficiently in controlled fermentation systems, often using low-cost substrates, and contain all essential amino acids necessary for human and animal nutrition. The rise in protein demand, coupled with environmental sustainability concerns linked to conventional animal agriculture, drives interest and investment in SCP solutions for food, animal feed, and dietary supplement applications.

Restraint: Consumer Awareness and Acceptance Challenges for Microbial Proteins

One of the major restraints on single-cell protein (SCP) market adoption is limited consumer awareness and acceptance of microbial proteins as food ingredients. SCPs are derived from microorganisms such as bacteria, yeasts, fungi, and algae, which are unfamiliar to many consumers. Research on alternative proteins highlights that food neophobia the reluctance to eat novel food items, significantly reduces willingness to adopt new protein sources, including microbe-derived ones. Factors such as unfamiliarity, perceptions of unnaturalness, or sensory expectations (taste, texture) contribute to hesitancy among potential consumers.

Even in developed markets, surveys show conflicting or limited evidence on acceptance levels, underscoring that consumers often perceive these proteins as “novel” and require education and familiarity before they are broadly accepted as mainstream foods. Regulatory frameworks also influence consumer confidence: in the United States, for example, the FDA requires rigorous toxicology and compositional data to grant microbial proteins GRAS (Generally Recognized as Safe) status before food use, adding time and cost before products reach shelves. These challenges, from psychological barriers such as novelty avoidance and cultural food norms to knowledge gaps about safety and benefits, restrict the pace at which SCP products can penetrate the broader human food market, despite sustainability and nutritional advantages.

Opportunity: Expansion in Human Food Applications, Including Fortified Foods and Beverages

Single-Cell Proteins (SCPs) present a meaningful opportunity in human food applications as supply chains evolve to meet global protein needs sustainably. SCPs offer high nutritional value, including essential amino acids, and can be incorporated into foods like baked goods, snacks, fortified foods, and beverages. As global per capita protein availability rises with an increase from around 85 g/day in 2010 to more than 90 g/day in 2021 food systems must diversify protein sources to support nutrition security without overburdening environmental resources.

Microbial proteins are particularly suited for fortification and functional ingredients because they can be tailored in composition and produced in scalable fermentation systems that do not require arable land or extensive water use. For example, SCP-based ingredients can be added to cereal products, plant-based beverages, and high-protein functional foods aimed at health-conscious consumers or populations with higher protein needs (e.g., older adults, athletes). Additionally, SCP technology enables production on diverse substrates, including certain food processing wastes, aligning with circular economy and sustainability goals.

With rising interest in alternative proteins and nutritional fortification, SCPs thus offer a significant opportunity to expand into everyday foods and beverages, supporting both dietary protein enrichment and global food system sustainability.

By Source Insights

Yeast is one of the oldest and most established microbial sources for single-cell protein (SCP) production. Yeast cells such as Saccharomyces cerevisiae can produce high levels of protein biomass (often 40-60 % of dry weight) and contain a broad spectrum of essential amino acids, making them nutritionally comparable to traditional protein sources like meat and soy. Yeast can also grow on inexpensive carbon substrates, including agricultural and industrial wastes, under relatively simple fermentation conditions with low environmental impact. These traits have led to widespread industrial adoption of yeast biomass for both animal and human nutrition. Yeast SCP is easier to scale and harvest than many alternatives because yeast fermentation technology is mature and widely deployed globally. Established infrastructure also supports the use of yeast in food and feed applications, reinforcing its dominant position among SCP sources.

By Application Insights

Animal feed remains the largest application for single-cell proteins largely because global demand for animal-derived protein (meat, milk, eggs) is rising rapidly. FAO data show that livestock products account for over 30 % of the global value of agriculture and more than one-third of human dietary protein, driving a substantial need for high-quality feed ingredients. At the same time, traditional feed protein sources such as soybean meal and fishmeal face supply limitations, price volatility, and safety concerns (e.g., contamination or disease risks), prompting feed producers to explore alternative proteins. SCPs, including yeast, bacterial, and algal proteins, offer a high-protein, safe, and sustainable alternative to conventional protein feeds. As poultry, swine, and aquaculture production expand to meet dietary protein demand, SCP’s application in animal nutrition has scaled accordingly, making animal feed the dominant end use in the SCP market.

North America Single-Cell Protein Market Trends

North America led by the United States and Canada, is the largest regional market for Single-Cell Protein (SCP) products, accounting for around 30-32 % of global SCP output in 2023 (≈380 000 t out of 1.26 m t). This dominance reflects strong biotechnology infrastructure, high private and public R&D investment, and early consumer acceptance of alternative proteins across food, feed, and supplement sectors. The U.S. regulatory environment (e.g., FDA evaluations for novel proteins) and well-established fermentation capabilities facilitate the commercialization of microbial protein products. Moreover, consumer awareness of sustainable and functional foods is high, accelerating SCP adoption in both human nutrition and animal feed formulations. These structural advantages have positioned North America at the forefront of SCP development and deployment globally.

Europe Single-Cell Protein Market Trends

Europe is a key SCP market because of policy emphasis on sustainability, food security, and reduced import dependence for protein feedstocks. The EU’s sustainability strategies (e.g., Farm to Fork) support alternative proteins to address the environmental impacts of traditional livestock systems, including high import reliance on soy and other protein feeds. Alternative proteins, including microbial and fermentation-based SCP products, are gaining traction as part of this strategy. European consumers are also relatively receptive to sustainable protein alternatives, with a high share of retail outlets featuring alternative protein products (including fermentation-derived and microbial proteins). These combined factors, regulatory encouragement, environmental policy frameworks, and strong food processing and distribution networks, make Europe a major and influential region for SCP adoption and innovation.

AsiaPacific Single-Cell Protein Market Trends

Asia Pacific is the fastest-growing regional market for single-cell protein due to rapid population growth, rising protein demand, and expanding animal agriculture sectors. The region’s population, already the largest globally continues to urbanize and increase dietary protein consumption, particularly in major economies like China, India, and Southeast Asia. Governments and industry actors in Asia Pacific are investing in biotechnology, feed innovation, and sustainable protein production to support food security and reduce reliance on imported protein feeds (e.g., soybeans). This has translated into robust SCP adoption in feed and emerging human food applications. As a result, Asia Pacific SCP markets are forecast to register higher growth rates compared with North America and Europe, reflecting both rapid domestic demand growth and strategic focus on scalable protein alternatives.

The global single-cell protein (SCP) market is competitive, led by players like The Kraft Heinz Company, Mizkan Group, and Unilever.
