To evaluate food authenticity and quality, organoleptic feature aroma very important, such that composition volatile organic compounds (VOC) unique in each aroma, providing a basis predict quality. Different types analytical approaches have been used assess VOC biomarkers other parameters food. The conventional are based on targeted analyses using chromatography spectroscopies coupled with chemometrics, which highly sensitive, selective, accurate authenticity, ageing, geographical origin. However, these methods require passive sampling, expensive, time-consuming, lack real-time measurements. Alternately, gas sensor-based devices, electronic nose (e-nose), bring potential solution for existing limitations methods, offering cheaper point-of-care analysis assessment.
