Notre extrait de th\u00e9 Oolong (OTE) est naturellement fonc\u00e9 car apr\u00e8s la cueillette, les feuilles de th\u00e9 sont ferment\u00e9es et oxyd\u00e9es pendant plusieurs semaines (sans \u00eatre expos\u00e9es \u00e0 une humidit\u00e9 excessive et \u00e0 l’oxyg\u00e8ne). Il a une dur\u00e9e de conservation tr\u00e8s longue, voire illimit\u00e9e. S’il est correctement stock\u00e9, l’OTE peut continuer \u00e0 vieillir naturellement et renforce son pouvoir de contraste en microscopie. C’est le tanin de l’OTE que nous utilisons car il est lui-m\u00eame un tr\u00e8s bon conservateur. En revanche, la solution aqueuse d’OTE ne se conserve que quelques heures (il faut donc la pr\u00e9parer juste avant de l’utiliser). <\/p>\n
*Astuce :<\/p>\n
La pr\u00e9servation des propri\u00e9t\u00e9s des extraits de th\u00e9 Oolong (OTE) est prolong\u00e9e lorsque les OTE sont conserv\u00e9s correctement. Pour ce faire, il convient de ne pas ouvrir souvent le r\u00e9cipient de stockage. En effet, \u00e0 chaque ouverture, il entre en contact avec de l’air humide, ce qui r\u00e9duit son pouvoir de contraste. Il est donc important de diviser l’extrait de th\u00e9 Oolong (OTE) et de le conserver en plusieurs portions dans un endroit frais. <\/p>\n
