The flavor characteristics of huitlacoche of 2 maize varieties harvested at 3 harvesting time
were evaluated by electronic tongue assisted detection technology.The results showed that the tastes of
huitlacoche included sweetness,umami,sourness and saltiness.The effects of 2 maize varieties on sweetness
and umami of huitlacoche were not significant,while the effects of harvesting time on sweetness and umami
were significant.The sweetness response value decreased as the delay of harvesting time.While,the umami
response value increased as the delay of harvesting time.The best harvesting time for huitlacoche was 17-
20 days after inoculation.So,the electronic tongue assisted detection technology will have great application
potential in huitlacoche production.
