La pectina è un polisaccaride presente nella parete cellulare dei vegetali superiori, responsabile della struttura dei frutti. La molecola è formata essenzialmente da acido D-galatturonico unito da legami alfa-(1,4). Le pectine di piante diverse presentano una struttura chimica comune, ma possono esserci differenze nella loro composizione e nella struttura durante la fase di maturazione. L’applicazione della pectina nell’industria alimentare è molto versatile, poiché questo additivo presenta proprietà gelificanti, addensanti e stabilizzanti e può essere utilizzato in un’ampia varietà di prodotti lattiero-caseari, carnei e da forno, gelatine, polpa di frutta, bevande e altri. Esistono diversi studi sull’utilizzo di diversi residui per l’estrazione della pectina, tuttavia, nonostante la guava (Psidium guajava L.) contenga una quantità ragionevole di pectina, esistono poche informazioni sul suo utilizzo come fonte di estrazione. Inoltre, si verifica una grande perdita post-raccolta di questo frutto. Gli studi sull’estrazione della pectina utilizzando la guava potrebbero contribuire allo sfruttamento del frutto, riducendo così le perdite.
