摘要: The urinary odors are commonly perceived as unpleasant. While numerous studies have identified the volatile organic compounds (VOCs) released from urine, odorants responsible for urine odor not well characterized. Furthermore, anecdotal reports suggest that of aged is different fresh urine. However, no study has yet to investigate specific VOCs In this study, we analyzed and compared samples, investigating changes in aged. We found an overall decrease concentration many VOCs, concluded was due evaporating it On contrary, some highly water-soluble such short branched-chain acids trimethylamine, increased. Their increased release most likely loss water subsequent ages. these may contribute
