Evaluating Consumer Products for Low Level Contaminants with High Temperature Dynamic Headspace

Abstract High density polyethylene (HDPE) and polyethylene terephthalate (PET) are widely used polymers for the storage of consumer products including bottled drinks. HDPE is typically used in milk jugs while PET is typically used in soft drink and bottled water bottles. These polymers can have glass transition temperature above 250°C (482°F) and can be difficult for most headspace ...

Determination of Furan in Coffee by Static and Dynamic Headspace-GC–MS

Abstract Coffees have aroma and taste based on where the beans are grown, roasting techniques, and flavor additives. One component of the bean responsible for the aroma and some of the taste are volatile organic compounds (VOCs). Furan is one VOC that has recently been investigated in food (1). An FDA method for furan in food uses static headspace and requires 30 min of incubation time at 60 ...

Determination of Hexanal in Foods Utilizing Dynamic Headspace GC/MS

Abstract Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids. Dynamic headspace sampling differs from static headspace sampling in that the headspace above the sample is swept with a gas onto ...
