Abstract
This review analyzes precision fermentation as a strategic tool for the future of the global food system, examining the interplay among technological advances, regulatory frameworks, factors influencing consumer acceptance, and associated ethical implications. Recently, synthetic biology has emerged as a prominent field, driven by the development of tools and technologies with the potential to transform multiple sectors of industrial production. In this context, precision fermentation stands out as a promising approach for the future of food production, enabling the generation of inputs that meet sustainability, ethical, and high-quality standards. Despite its significant advantages, this technology still faces limitations in its large-scale application. These include challenges related to production scalability, variations in compound structure and functionality due to difficulties in post-modification translational processes, as well as differences in consumer acceptance and in the establishment of regulatory frameworks across diverse global and cultural contexts. This review highlights precision fermentation as a promising avenue for producing inputs for the global food industry. Discusses its technical, economic, and regulatory limitations while assessing issues related to consumer acceptance. In addition, it examines ongoing efforts and emphasizes the need to overcome these challenges to establish this technology as a promising alternative for more sustainable food production.
Precision fermentation has emerged as a promising biotechnological approach with significant potential to address global challenges, such as climate change, resource scarcity, and rising protein demand. This interdisciplinary review examines the technological foundations, economic prospects, and regulatory framework of precision fermentation, with a particular focus on the European Union (EU) market. Scientifically, precision fermentation is an extension of traditional fermentation, employing controlled microbial systems to produce specific compounds with high efficiency.
The precision fermentation market is expanding rapidly, driven by strong investment activities, increasing numbers of startups and growing consumer interest in sustainable food innovations. However, market data remain inconsistent because of varying definitions and early stage industry dynamics. Key economic challenges include high production costs, limited large-scale fermentation capacity and technical barriers to scaling up and downstream processing. While environmental assessments suggest substantial reductions in land and water use and greenhouse gas emissions compared to conventional livestock systems, uncertainties remain due to limited commercialization. From a regulatory perspective, precision fermentation products in the EU are primarily governed by Novel Food legislation rather than GMO-specific laws, although the use of genetically modified microorganisms triggers additional compliance requirements. Regulatory complexity, lengthy approval processes and inconsistent implementation across member states present significant barriers to startups.
Overall, while precision fermentation holds transformative potential for sustainable food systems, its successful commercialization depends on advances in scaling technologies, clearer regulatory pathways, and coordinated support from policymakers, investors, and scientific institutions.

This work explores the development of animal-free proteins produced in laboratory settings using innovative technologies such as precision fermentation, submerged fermentation, plant cell culture, and molecular engineering, which enable the production of high-quality proteins without relying on animal farming or large-scale traditional agriculture.
The escalating global population and the environmentally inefficient nature of livestock-based protein production are intensifying demand for sustainable and scalable protein alternatives. Microbial biosynthesis, employing engineered cell factories, represents a pivotal strategy for producing functional proteins with a reduced ecological footprint. This review comprehensively examines the biosynthesis of alternative proteins (APs) via microbial precision fermentation, encompassing diverse categories including coloring proteins, flavoring and taste proteins, structuring and texturizing proteins, nutritional and functional proteins, food processing and enabling proteins, and special functional proteins. Enabling technologies, from fermentation feedstock and microbial host selection to genome/metabolic engineering, bioprocess optimization via response surface methodology/artificial neural networks, and downstream purification, are critically analyzed. Emerging strategies demonstrate substantial progress in enhancing microbial titers, achieving functional mimicry, and advancing regulatory readiness. However, persistent challenges include precise flavor replication, nutritional completeness, and food safety concerns such as allergenicity and process contaminants. Potential solutions, including advanced metabolic engineering, refined protein extraction, biocontainment strategies, and transparent regulatory frameworks, are discussed. By integrating technological innovation with targeted application mapping and regulatory foresight, this review outlines a roadmap toward scalable, safe, and functionally robust microbial AP platforms, thereby contributing to the transition toward a sustainable food system.

ABSTRACT The functional food industry has increasingly focused on postbiotics due to challenges associated with maintaining probiotic viability and safety concerns in immunocompromised individuals. Postbiotics are defined as inanimate microbial cells and/or their metabolites that do not require viability but retain health promoting properties and technological stability. This stability has positioned postbiotics as promising alternative ingredients for food engineering applications where processing robustness is critical. This review provides a comprehensive, engineering‐oriented evaluation of postbiotics as next‐generation functional food ingredients. Current definitions and classification schemes are first summarized, followed by an assessment of how innovative thermal and non‐thermal production methods can be integrated into food processing systems. Analytical and advanced characterization techniques used for the qualitative and quantitative assessment of postbiotics in food matrices are then examined, alongside a comparison of the technological advantages and safety profiles of postbiotics relative to probiotics. Applications across different food matrices are reviewed and summarized in detailed tables, and commercially available postbiotic products are compiled together with their key specifications. Major challenges limiting broader industrial adoption are also addressed, including interactions with food components, the absence of standardized inactivation protocols, regulatory uncertainties, and the lack of harmonized industrial‐scale production methods. By consolidating these dimensions, this review identifies key research gaps, particularly the need for standardized inactivation and characterization protocols that can support regulatory alignment and evidence‐based health claims and outlines future directions to improve process efficiency and support the development of safe, sustainable postbiotic‐based foods.
Cultured meat production represents a revolutionary approach to addressing the mounting challenges of conventional animal agriculture, including environmental degradation, animal welfare concerns, and food security issues. This comprehensive review examines the current state of cultured meat technology, encompassing advances in cellular agriculture, bioprocessing innovations, regulatory frameworks, and consumer acceptance patterns. Recent developments in scaffolding technologies, bioreactor design, and cost reduction strategies have significantly enhanced the commercial viability of cultured meat production. Regulatory approvals in Singapore and the United States mark critical milestones, while European and other global markets continue developing comprehensive frameworks. Consumer acceptance studies reveal regional variations, with North American markets showing particularly strong receptiveness. Environmental life cycle assessments demonstrate potential for substantial reductions in greenhouse gas emissions, land use, and water consumption compared to conventional meat production. However, significant challenges remain in achieving cost competitiveness, scaling production infrastructure, and addressing consumer concerns about food safety and product quality. This review synthesizes current research findings to provide insights into the future trajectory of cultured meat as a sustainable protein alternative.
