Abstract:		"In an effort to identify and quantify important volatile organic compounds (VOCs) released from sports beverage containers commonly used for storage and distribution, three brands of sports beverages with poly ethylene terephthalate (PET) and metal cans were analyzed through headspace-solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS). Out of 80 volatile compounds identified from all container types, I-limonene recorded the highest concentration (34.3-118 pmol mol(-1)) along with 12 other VOCs detected most frequently (more than 3 out of all 6 products) such as 2-methyl-6-methylene-2,7-octadiene, alpha-terpineol, decanaldehyde, and p-isopropyltoluene. When each container was filled up with water and analyzed after a long-term storage (49 days), a total of 14 VOCs were detected. According to our analysis, all the VOCs detected from either beverage or container materials were below the safety limits prescribed previously by diverse agencies. However, an extension of these analyses may be necessary for other beverage types, as certain VOCs can be migrated from container materials"
