Application Notes: Food and Beverage

Protein analysis plays a large role in the production of foods, pet foods, and even pharmaceutical medicines. But first, the amino acids in the protein must be broken down.

In this study, SPME Arrow sample preparation was tested for the analysis of furan and alkylfurans in baby formula and coffee samples.

Classical protocol of amino acid hydrolysis needs up to 24 h of reaction time. Using the Discover Prep, the same level of acid and base hydrolysis was achieved in minutes.

This application note describes two approaches for achieving a robust, multiresidue pesticide analysis in 10 min by GC–MS/MS for over 200 pesticides in spinach.

Identification of polyphenolic catechin compounds for health and industrial quantification and quality control of tea products

Pesticide testing is crucial to assessing the safety of fruits and vegetables for consumption. The traditional extraction method for pesticides from produce is the QuEChERS method. This method is tedious, manual, time consuming, and wasteful. Thus, there is a need for improved methods of extraction. In this application note, the EDGE®, in combination with Q-Matrix™ Hydra, a water-removing sorbent, was used to extract a panel of pesticides from 10 g of homogenized cucumber, tomato, and green pepper in less than 9 min. The recoveries of the pesticide panel were greater than 70% for each matrix tested, and these results were highly reproducible. The EDGE provides a fully automated extraction that combines both the sample and sorbent into one sample vessel, alleviating the human burden of extraction and the need for multiple sample transfers.
