Feed Analysis and Animal Nutrition: Electronic Nose as a Diagnostic Tool

摘要

The electronic nose is an instrument that comprises an array of electronic chemical sensors and anappropriate pattern recognition system and capable of recognizing simple or complex volatile organiccompounds’ (VOCs) profiles associated to a product odour. The e-nose analysis of VOCs is of increasinginterest as an analytical tool in many research areas, such as agricultural, food, pharmaceutical, biomedical,cosmetics, environmental, food, manufacturing, military. In the food industry, the electronic nose couldrepresent a rapid and reliable tool for quality and safety assessment, freshness and shelf-life evaluation,authenticity assessment, foodstuff recognition, and process monitoring. This paper provides an overview ofthe applications of electronic nose in feed analysis and animal nutrition. Focus is placed on the applications asan analytical tool for quality control and management in the cereal and pet food industry. Further, this paperprovides a critical outlook on the developments needed for transitioning of electronic nose use from researchto industrial application in real contexts.
