A Routine Method for the Extraction and HPLC-DAD Profiling of Major Plant and Food Carotenoids

Methods in Molecular Biology, vol 2083. Humana, New York, NYCarotenoids are ubiquitously present in Nature, and especially in plants and derived foods. The carotenoid profiling is necessary to understand relevant aspects in relation to their biochemistry and genetics, as well as their important roles on human health and animal ecophysiology. Here we propose a simple methodology for the routine extraction and efficient HPLC separation of the most common plant and food carotenoids from plant and animal origins.The author thanks to the Spanish Government (projects AGL2017-85368P and CaRed Network BIO2015-71703-REDT and BIO2017-90877-REDT) for financial support

Changes in biogenic amines in herring stored under modified atmosphere and vacuum pack

Changes in 10 biogenic amines during the storage of herring in ice, in boxes without ice, in a modified atmosphere, and in vacuum packaging were investigated. The highest level of histamine was obtained from herring stored in boxes without ice, followed by herring stored in VP, ice, and MAP. Putrescine and cadaverine contents increased during the storage of herring held in ice, reaching levels of 4.0 mg and 23.7 mg/100g muscles at 16 d of storage, respectively. No significant differences were found in histamine concentrations within the treatments during the early stages of the storage period. However, there was a significant difference (P < 0.05) towards the end of the storage period in all treatments except between VP and ice
