CHE SIGNIFICA TANNIN IN INGLESE
Tannino
Un tannino è un composto polifenolico vegetale astringente e amaro che si lega e precipita le proteine e vari altri composti organici tra cui aminoacidi e alcaloidi. Il termine tannino si riferisce all'uso di tannini di legno di quercia in abbronzatura di animali in pelle; Da qui le parole "abbronzatura" e "abbronzatura" per il trattamento della pelle. Tuttavia, il termine "tannino" per estensione è ampiamente applicato a qualsiasi composto polifenolico di grandi dimensioni contenente idrossili sufficienti e altri gruppi idonei a formare complessi forti con varie macromolecole. I composti del tannino sono ampiamente distribuiti in molte specie di piante, dove svolgono un ruolo di protezione dalla predazione e forse anche come pesticidi e nella regolazione della crescita vegetale. L'astringenza dai tannini è ciò che provoca la sensazione di asciugatura e di rottura in bocca a seguito del consumo di frutta non sgranata o di vino rosso. Allo stesso modo, la distruzione o la modifica dei tannini con il tempo svolge un ruolo importante nella maturazione della frutta e nell'invecchiamento del vino. I tannini hanno pesi molecolari che vanno da 500 a più di 3.000 e fino a 20.000.
