Impact of Protein Concentrate Production on Mycotoxin Mitigation: A Systematic Review

The plant-based protein industry has explored new material sources, such as agro-industrial by-products and extraction techniques based on chemical properties assisted by ultrasound, high pressure and other tools to improve the yield and functionality of protein concentrates. However, promising by-products from vegetable processing are susceptible to incidental and natural contaminants, mainly mycotoxins. Adopting sustainable strategies and understanding how they affect mycotoxin fate during processing remains a challenge to ensure food security. In this study, a systematic literature review and bibliometric analysis were conducted to identify reliable pre-treatments and treatments for producing protein concentrates and evaluate the efficiency of technologies to mitigate mycotoxin bioaccessibility. Searching for research in Scopus, Web of Science and ScienceDirect (2010-2024) identified 3688 scientific articles on techniques to improve the yield and functionality of recovered proteins, but only three studies addressed mycotoxin fate. Aflatoxin, the most prevalent mycotoxin in raw materials, was the only one considered, highlighting that chemical and enzymatic treatments may help mitigate mycotoxicological risks in protein concentrates. Results indicate a gap in plant-based food security regarding mycotoxin contamination, which must be addressed through mitigation strategies aligned with efficient processes to ensure sustainable and safe plant protein-based foods.
