Analysis of Contaminated Samples by DPiMS-2020 (1): Detection of Surfactants in Beverages

User Benefits

- Analysis by the PESI method is fast and simple, and does not require complex sample preparation. - A technique that enables simple judgment of the presence of detergents (surfactants) in beverages was developed. - Simple and high sensitivity screening for contamination by foreign substances is possible.

Introduction

A diverse range of cases of adulteration or contamination of beverages and food products by foreign substances has been reported, including contamination by familiar chemical substances. For this reason, an enormous number of chemical substances must be treated as analysis targets in inspections of beverages and food products when contamination is suspected. To conduct this kind analysis efficiently, it is necessary to develop a quick and accurate screening technique for the presence of contaminants. In this research, a high sensitivity detection technique using the simplest possible sample preparation procedure was developed, assuming contamination of beverages by dishwashing detergents (surfactants), which is a frequent type of product contamination. This article also reports the results of a study of the applicability of this technique as a simple screening method for medicinal toxicants in beverages suspected of contamination.
