Like other agricultural products, coffee is susceptible of colonization by mycotoxin-producing fungi and therefore, the presence of mycotoxins. These chemical hazards can pose a risk for consumers, as some of them are potentially carcinogenic, neurotoxic, or immunosuppressive. Several countries worldwide have established maximum legal limits on the final product regarding ochratoxin A (OTA), but this leads to inefficiencies in the coffee value chain, as there is uncertainty if a batch may be under the legal limits at the time of reaching the consumers. The application of Risk Management Metrics can be a useful tool for managers to forecast if a particular batch of coffee could be suitable for a determined target market. In this study, a cross-case analysis of the coffee production chain was performed, and quantitative thresholds were established along the different steps. This information can provide managers with up-to-date information regarding the potential use of each batch, minimizing food waste, assuring food safety, and improving chain efficiency.</p></div>","PeriodicalId":54291,"journal":{"name":"Current Opinion in Food Science","volume":"54 ","pages":"Article 101100"},"PeriodicalIF":9.9,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2214799323001157/pdfft?md5=eca8eb8734396da415f0da2864c81de7&pid=1-s2.0-S2214799323001157-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91959845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review aims to provide a recent overview of the research advancements in CR-loaded nanocarriers and to explore their potential benefits in food and pharma applications. Various research studies have been conducted on different nanocarriers for the delivery of CR, and their findings suggest that optimal encapsulation can improve the stability of CR, thereby preserving its therapeutic potency.
