Traceability of livestock feeding conditions based on the analysis of the volatile organic compounds profile in the food product.
Résumé
The conditions governing animal production and technological processing of animal derived food products are determinant factors of meat and meat products quality, making them a key target for sustained research in the field of food product authentication. Volatile Organic Compounds (VOCs) are promising candidate biomarkers of the conditions of production of animal-derived food products. They may originate directly from the food ingredients consumed by the animals, from the rearing environment, or from the animal metabolism. As metabolism end-products, VOC composition of tissues and fluids may vary according to the physiological status of the animal which in turn is conditioned by the conditions of production; the VOC composition may also reflect variation in the transformation steps during the processing of raw tissues and fluids into animal-derived food products. The present paper aims to demonstrate the relevance of VOC analyses for authenticating any key information related to meat, milk and sea foods production chains.
