Analyse van vluchtige organische stoffen in verpakt voedsel

Volatile Organic Compounds (VOCs) are unavoidable aspects of foods and their packaging. Some VOCs provide pleasant odors and contribute to flavor profiles, while others can cause negative health and environmental effects. In microwave popcorn, diacetyl and possible other related substances (DAPORS) have recently become an emerging concern. Eight DAPORS were analyzed using SPME/GC-MS in both high-fat and low-fat varieties of microwave popcorn. A combination sensor array technology was developed in conjunction with a proprietary neural network. The array was successfully trained to detect and predict contamination in thermoplastics (Afstudeerverslag Iowa State University).
