TOF-MS based characterization of polyglycerol polyricinoleate (PGPR) samples.
Time-of-flight mass spectrometry (TOF-MS) was used to unravel the composition of commercial polyglycerol polyricinoleate (PGPR) samples, by identifying the various molecular species present. To cover the broad range of molecular weights for the present species, a combination of three ionisation conditions was used. Species exceeding the molecular weight of pentaglycerol hexaricinoleate were difficult to detect. Over 100 molecular species were observed and identified in the analysed samples, including free polyglycerols, ricinoleates, and PGPR-esters. Commercial PGPR samples were shown to be mainly composed of esterification products of di-, tri-, and tetraglycerol, while the esterification degree mainly varied from 1 to 5. The TOF-MS analysis was proven to be reproducible with a relative standard deviation (RSD) below 2.86% for three independent measurements on different days. The method proved to be very suitable to evaluate batch-to-batch variations and to compare the composition of different types of commercial PGPR's. Moreover, this method can be applied to monitor the quality of PGPR products during the synthesis process. Furthermore, it can also provide fundamental knowledge for optimizing PGPR composition to improve its functionality.
期刊介绍：
Food Additives & Contaminants: Part A publishes original research papers and critical reviews covering analytical methodology, occurrence, persistence, safety evaluation, detoxification and regulatory control of natural and man-made additives and contaminants in the food and animal feed chain. Papers are published in the areas of food additives including flavourings, pesticide and veterinary drug residues, environmental contaminants, plant toxins, mycotoxins, marine biotoxins, trace elements, migration from food packaging, food process contaminants, adulteration, authenticity and allergenicity of foods. Papers are published on animal feed where residues and contaminants can give rise to food safety concerns. Contributions cover chemistry, biochemistry and bioavailability of these substances, factors affecting levels during production, processing, packaging and storage; the development of novel foods and processes; exposure and risk assessment.
