La pectina è un eteropolisaccaride ad alto peso molecolare costituito da catene lineari di acido poligalatturonico, più o meno esterificato con metanolo. Essa è ampiamente diffusa nel regno vegetale e rappresenta un additivo fondamentale per diverse applicazioni industriali. Con questo elaborato finale si propone di esplorare le proprietà chimiche, fisiche e funzionali della pectina, le sue varie applicazioni nella formulazione di alimenti, nonché esaminare i diversi metodi di estrazione della pectina da fonti vegetali, valutando l'impatto delle condizioni operative sulla resa e sulla qualità del prodotto finale. L’elaborato ha dedicato particolare attenzione anche all'utilizzo della pectina in ambito farmaceutico. Si è preso in esame le caratteristiche mucoadesive per contrastare la stipsi in soggetti a rischio e la capacità di veicolare principi attivi durante l'assorbimento intestinale. Inoltre, sono state discusse le prospettive future sul suo utilizzo, come la formulazione di prodotti a base vegetale per vegani, diabetici e per pazienti affetti da disfagia.

Abstract
Pectin is a high molecular weight heteropolysaccharide composed of linear chains of polygalacturonic acid, more or less esterified with methanol. It is widely present in the plant kingdom and serves as a crucial ingredient for various industrial applications. This project aims to delve into the chemical, physical, and functional properties of pectin, along with its diverse applications in food formulation. We have scrutinized different methods of extracting pectin from various plant sources, evaluating the impact of operational conditions on both yield and the quality of the final product. The work has also devoted particular attention to the use of pectin in the pharmaceutical field, examining its mucoadhesive properties to counteract constipation in at-risk individuals and its ability to deliver active principles for intestinal absorption. Furthermore, prospects for pectin utilization have been discussed, such as the formulation of plant-based products for vegans, diabetics, and addressing dysphagia issues.File | Dimensione | Formato | |
