Summary
Plant protein processing faces challenges from mycotoxins in by-products. Research shows chemical and enzymatic treatments can reduce these risks, ensuring safer plant-based foods.
Area of Science:
- Food Science and Technology
- Agricultural By-products Valorization
- Food Safety and Toxicology
Background:
- The plant-based protein sector is expanding, utilizing agro-industrial by-products for protein concentrate production.
- These valuable by-products are often contaminated with mycotoxins, posing a significant food security risk.
- Sustainable processing strategies are needed to manage mycotoxin contamination during protein extraction.
Purpose of the Study:
- To systematically review and bibliometrically analyze literature on protein concentrate production techniques.
- To evaluate the efficiency of various technologies in mitigating mycotoxin bioaccessibility in plant-based protein ingredients.
- To identify reliable pre-treatments and treatments for producing safe and functional protein concentrates.
Main Methods:
- Systematic literature review and bibliometric analysis of research published between 2010-2024.
- Searches conducted in Scopus, Web of Science, and ScienceDirect databases.
- Focus on studies related to protein concentrate yield, functionality, and mycotoxin fate during processing.
Main Results:
- A vast body of research (3688 articles) exists on protein recovery techniques, but only three studies addressed mycotoxin fate.
- Aflatoxin was the primary mycotoxin investigated, prevalent in raw plant materials.
- Chemical and enzymatic treatments show potential for mitigating mycotoxicological risks in protein concentrates.
Conclusions:
- A significant knowledge gap exists regarding mycotoxin contamination and mitigation in the plant-based protein industry.
- Further research is crucial to develop and validate strategies for managing mycotoxins during processing.
- Integrated approaches combining efficient processing with effective mitigation are essential for sustainable and safe plant protein-based foods.

01:28Microbial Bioremediation of Pesticides
Pesticides often feature structurally complex chemical architectures, incorporating halogen groups and multiple aromatic rings. These characteristics confer high chemical stability, rendering many pesticides resistant to natural degradation processes. This resistance poses significant environmental concerns, as persistent pesticide residues can accumulate in ecosystems and affect non-target organisms.Despite the inherent stability of many pesticides, certain microorganisms possess the metabolic...

Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...
01:29Sources of Food Contamination
Contamination of food by microbial agents and natural toxins poses significant risks to public health. These hazards can be introduced at various points across the food supply chain, ranging from environmental sources to processing and storage stages. Understanding these contamination pathways is critical for developing strategies to ensure food safety.Seafood is particularly vulnerable to contamination through both environmental exposure and microbial colonization. Toxins from harmful algal...
01:22Bioreactor Controls-III
Strain improvement is a foundational strategy in industrial microbiology aimed at maximizing microbial productivity, particularly because natural isolates typically yield commercially valuable products in very low concentrations. Although optimizing the culture medium and environmental conditions can improve yields, these adjustments are inherently limited by the organism’s genetic potential. As a result, the focus shifts toward genetic modifications to enhance biosynthetic capacity. The...

Continuous fermentation is a key strategy in industrial ethanol production, particularly when efficiency, scalability, and high yields are essential. This approach allows for uninterrupted operation and optimized resource utilization. The primary feedstock, corn starch, undergoes enzymatic hydrolysis facilitated by α-amylase and glucoamylase. These enzymes break down the starch into fermentable sugars such as glucose, which are readily assimilated by fermentative microorganisms.Fermentation...
