Title
(EN) A PROCESS OF AROMA RECOVERY FROM TEA LEAF
(FR) PROCÉDÉ DE RÉCUPÉRATION D’ARÔMES À PARTIR DE FEUILLES DE THÉ
Abstract
(EN)
The present invention relates to a process for aroma recovery from tea leaf comprising the steps of: incubating fresh tea leaf at a temperature in the range 4 to 80°C under anaerobic conditions for a period of 4 to 72 hours; subjecting the incubated leaf to comminution to produce dhool; fermenting the comminuted dhool; and recovering aroma from the dhool while partially drying the dhool in a low-convection dryer.
(FR)
La présente invention concerne un procédé de récupération d’arômes à partir de feuilles de thé comprenant les étapes de : incubation de feuilles de thé fraîches à une température dans la plage de 4 à 80 °C dans des conditions anaérobies pendant une période de 4 à 72 heures ; soumission des feuilles incubées à un broyage pour produire un dhool ; fermentation du dhool broyé ; et récupération d’arôme à partir du dhool tout en séchant partiellement le dhool dans un séchoir à convection faible.
