Development of Polyphenolics Extracts from Mexican Crops as Natural Antimicrobial Agents for Postharvest Treatments

Abstract

In the last decade, the use of natural antimicrobial agents, like polyphenolic extracts in postharvest applications, has gained attention. However, a significant challenge lies ahead. Demonstrating these agents’ commercial-scale production feasibility, practical applications, and economic viability compared to traditional agrochemicals is crucial. This review focuses on the achievements and obstacles in using polyphenolic extracts from Mexican crops as natural antimicrobial agents against postharvest phytopathogens and foodborne microorganisms. A comprehensive knowledge of the molecular mechanisms in vitro and in vivo, as well as plant systems, is essential for better results. Toxicity assessments and an evaluation of the impact on fruit quality are needed. Incorporating coating and encapsulation techniques can enhance the effectiveness of extracts. An integrated approach is needed for efficient, cost-effective control throughout the preharvest, harvest, and postharvest phases. Successful commercialization depends on the cost–benefit analysis, infrastructure, raw materials, local needs, and technical facilities, among other factors. Additionally, incorporating strategies related to circular economy can improve plant residue utilization and enhance technological and marketing approaches.
