their performance is unstable: most antimicrobial metabolites are sensitive to environmental factors such as temperature and pH, prone to degradation and inactivation during processing and storage, and their antimicrobial efficacy can be further impaired by interactions with components in complex food matrices - the natural yield of antimicrobial substances is low; fermentation optimization and the complex processes involved in metabolite extraction and purification lead to high production costs, making them difficult to compete with chemical preservatives - large-scale fermentation is susceptible to various factors, resulting in unstable batch-to-batch yield and activity of products, difficulty in ensuring strain consistency, and great challenges in quality control

The paper identifies a gap in the understanding of the potential of solid-state fermentation for the development of functional food ingredients. The gap concerns the lack of standardization in fermentation conditions, extraction procedures, and analytical assays, making it difficult to compare results across studies. The paper notes that the mechanistic interpretation of solid-state fermentation-induced functional changes is limited, and further research is needed to understand the relationships between microbial metabolites and observed responses.
