Profiling of Volatile Organic Compounds in Milk and Orange Juice Using Headspace Analysis
Volatile organic compounds, VOCs, present in liquid food products play a very important role in flavor and aroma characteristics. The monitoring of these VOCs are extremely important when controlling a manufacturing process, investigating adulteration, and determining product quality. In the past, a static headspace technique wouldn’t yield enough data to make testing practical. Therefore a purge and trap technique was employed, but the main problem faced is having to deal with the moisture.
Headspace analysis of volatile compounds offers many benefits. Some of those being are a cleaner analysis, potentially quicker run times, and elimination of possible system contamination from high concentrated samples. Until now, typical headspace samplers could not achieve the needed low-end detection required by the testing laboratory.
A new headspace sampler has been developed for the testing of VOCs and is capable of unprecedented low-end detection. By incorporating EPA approved trapping techniques, the HT3 Headspace sampler is now capable of offering purge & trap analytic performance.
