The migration of antioxidants including α-tocopherol (AT) and butylated hydroxytoluene (BHT) from durian rind cellulose reinforced poly (lactic acid) (PLA) biocomposites into 95% ethanol and its effect on stability of edible oil were investigated. The biocomposites materials containing 5% w/w antioxidant were compounded using Brabender internal mixer followed by hot press machine and were then placed in contact with 95% ethanol at 27°C and 37°C. Released antioxidants were measured by UV-spectroscopy for 45 days. The material containing BHT generated the faster release than α-tocopherol. Both of antioxidants released at 37°C faster than 27°C. The faster release of antioxidant from each condition resulting inhibition of lipid oxidation. Oxidative stability of edible oil was investigated by monitoring of peroxide value (PV) of edible oil. The result was found that edible oil contact with biocompotises containing BHT showed lower PV compared to α-tocopherol during storage. Therefore, it can be summarized that BHT is suitable antioxidant to be used in active packaging application for edible oil.
Traditional methods for detection of foodborne pathogenic bacteria in food and clinical samples are typically time‐consuming and require multiple steps or even skilled persons for identification and confirmation of pathogens. Multiple serious pathogens including Escherichia coli, Salmonella spp., Listeria monocytogenes, Campylobacter jejuni, and Vibrio spp. have been linked to foodborne diseases and outbreaks worldwide. Rapid, reliable, and less labor intensive detection methods can simplify the steps for pathogen detection for routine testing or monitoring of food samples as well as for following‐up on foodborne illness cases by testing clinical samples. Monitoring of pathogens can become more common and effortless to perform. Immediate responses to potential pathogen contamination in foods can be one of the most effective ways to control foodborne outbreaks. This section reviews the principles and characteristics of some recent rapid detection methods, including (i) immunoassays and nucleic acid‐based detection platforms and (ii) tools based on metabolites released or consumed. As these methods have gained interest for use to detect pathogens in both food and clinical samples, a perspective on the future directions is also described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
