Quantitation of Policosanols and Phytosterols in Brans by GC/MS

User Benefits

- No dilution re-runs of high positives by an extended calibration curve range - Automatic positive confirmation by relative ion intensities according to 2002/657/EC

Introduction

Functional foods such as brans, wheat and tea have gained popularity in modern diet due to an increasing number of scientific discoveries indicating that certain dietary factors are connected to disease. With the growth of the functional foods market, quantitation of existing functional nutrients as well as qualification of new ones are of paramount interest to both food producers and consumers. Shimadzu Corporation Japan has conducted a collaborative research with National Agriculture and Food Research Organization (NARO) on the relation between the origin of food products and the composition of their functional nutrients (e.g. policosanols and phytosterols). In this article, 6 policosanols and 3 phytosterols were quantitated in 48 bran samples (Fig. 2). The otherwise time-consuming analysis of the 48 samples was expedited by LabSolutions Insight^TM with its automatic positive confirmation features regarding relative ion intensities and retention times. Multivariate analysis was also performed with Orange to explain which compounds, besides the 6 policosanols and 3 phytosterols, played a significant role in distinguishing sample clusters among the 48 samples.
