Polycarbonate (PC) is a polymer containing Bisphenol A (BPA) monomers in its structure. It is frequently used in manufacturing consumer goods such as food storage containers, reusable water bottles, infant feeding bottles, microwave containers and microwaveable cups. Under varying pH and temperature conditions, additives used in the plastic manufacture can leach in trace levels into the food in contact and negatively affect human health over time. Therefore, quantitative determination of BPA in food can be of great significance. The present study analysed the migration of BPA in coffee from different qualities of polycarbonate microwaveable cups under the influence of microwave heating by reversed-phase ultra-high-performance liquid chromatography (UHPLC). The amount of BPA detected in samples ranged from undetected to 391.105 ± 0.05 μg kg−1. Results obtained indicate that BPA migration is minimal in good-quality polycarbonate cups. Poor-quality cups are accelerated time-dependent; increased contact duration between polycarbonate and hot contact medium leads to more significant BPA migration. Furthermore, the BPA leaching process is enhanced during microwave heating due to high temperatures reached in a short time. © 2022 Institute of Food, Science and Technology (IFSTTF).
Risk of Developing Antimicrobial Resistant Listeria monocytogenes in India: A Short Narrative Review
(National Nutrition and Food Technology Research Institute, 2022) Snigdha Homroy; Anjana Kumari; Aparna Agarwal; Abhishek Dutt Tripathi
Background and Objective: Rampant application of antimicrobial drugs in food sectors triggered the development of resistance within the microorganisms in the surrounding environment. Due to the reduced susceptibility towards existing drugs, these microorganisms have an increased survival rate when treated. The emergence of this complication in the common food-borne pathogens is worrisome. Several antimicrobial-resistant variants of known infectious bacteria have been discovered. Listeria monocytogenes is one among those ‘superbugs’ bringing such public health challenges to be tackled. This article aims to review India's current situation and stance regarding the progressive issue of antimicrobial resistance and listeriosis. Results and Conclusion: The issue of antimicrobial resistance has been recognized at all food industry and health care domain levels. Solutions are constantly being made to combat the obstacle, but the antibiotic resistance crisis does not seem to retard. Despite the awareness, regulations, and restraints implemented across the globe, researches hint towards rising antimicrobial usage and the ensued more threatening infections. India's step towards curbing antimicrobial resistance is at par with other global policies and intends to lower the resistance development rate among all pathogens. Till now, Indian authorities and the public have shown insouciance towards listeriosis. There are no special rules targeting Listeria monocytogenes in India, as opposed to stringent regulations in many western countries. The Indian government and all associated authorities must study and develop plans to establish standards and statutes to control listeriosis. Above all, set up a surveillance system to monitor the causes of food-related illnesses across the country. © 2022. All Rights Reserved.

This study investigates the efficacy of rosemary extract (RE) in stabilizing structured lipids (SL) developed using perilla seed oil (PSO) and palmolein (PO) under accelerated storage conditions. The oil samples, comprising PSO, Blend, and SL formulations with and without RE (1500 ppm) and BHT (200 ppm), were studied for their storage stability during a 30 day storage period at 65 °C, with the analysis carried out at 6 day intervals. Oxidative properties were comprehensively assessed, including both physical attributes (color, viscosity, and refractive index) and chemical parameters (peroxide value, free fatty acid (FFA), p-anisidine value, TOTOX value, conjugated dienes, and trienes). The results demonstrated that RE-enriched oil samples exhibited significantly higher oxidative stability (p < 0.05) compared to the control group. SL added with 1500 ppm of RE exhibited notable enhancements in quality parameters, showcasing reductions in FFA, TOTOX value, conjugated diene, and triene value by 44.01%, 35.42, 39.03, and 47.36, respectively, when compared to SL without any antioxidant. The RE at 1500 ppm concentration showed a similar effect as the synthetic antioxidant BHT at 200 ppm. Also, the RE demonstrated potent inhibition of the oxidation of polyunsaturated fatty acids, thereby contributing to the improved oxidative stability of the SLs. Furthermore, SL with RE also exhibited reduced degradation of the tocopherol content and total phenolic content during the storage period. Principal component analysis demonstrated that SL and blend followed similar oxidative characteristics as they fell within the same quadrant. These findings underscore RE as a potent source of antioxidants capable of scavenging free radicals and enhancing the oxidative stability of omega-3 fatty acid-rich SLs. © 2024 The Authors.
