  9. 9. MOOSY32 eNose in action MOOSY4 To sum up COST Contact Group Food Industry Medical app eNose VS Truffle Classification The systematic determination of ripeness at harvest is not trivial. Truffles must have a specific level of maturity; otherwise, they are perceived by the consumer as having a poor quality. To determine if a truffle is ripe, we developed a prototype for the truffle industry with only eight inexpensive MQ sensors. 9 / 18 GSYM: SENSORS & MAGNETISM GROUP
