Sample Preparation for HPLC Analysis of Confectionery

Like all foodstuff, confectionery is subjected to strict quality controls. Parameters of interest are, for example, nutritional value, moisture or fat content, or the quantification of particular ingredients, such as vitamins or alkaloids. Typically, chromatographic methods like High Performance Liquid Chromatography (HPLC) are used to analyze food samples. Most analytical methods only require a few milligram or gram of sample; the previous size reduction/homogenization process ensures that the small analysis sample is representative of the entire laboratory sample, thus allowing for reproducible results. Moreover, homogenized samples show a much better extraction behavior.
