Aroma profiling of pet food using high-capacity sorptive extraction and TD–GC×GC–TOF MS

Aroma profiling of pet food using high-capacity sorptive extraction and TD–GC×GC–TOF MS

This study demonstrates the use of the INSIGHT flow modulator for TD–GC×GC–TOF MS aroma profiling of meat-based cat food. We show that the enhanced separation provided by GC×GC, combined with sensitive, high-capacity sorptive extraction, ensures that trace off-odour components can be reliably separated and detected.

Introduction

Pet food manufacturers place great importance on the aroma of their products, as off-odours may be unappealing to both the pets and their owners. Confident identification of the volatile organic compounds (VOCs) from pet food can help these companies better understand the factors governing the release of pleasant and unpleasant aromas.
