IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca
IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.
AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.
EnglishIn this work, bio-microcapsules of chitosan have been developed by a membrane process using both polymeric and ceramic membranes. This technique permitted the formation of monodispersed bio-polymer droplets which were then cross linked with a natural additive adapted for this polymer structure that enhanced the water resistance of chitosan. Furthermore, two different types of natural antimicrobial were included in the capsules making the loading both during their production and after the droplet formation. The most effective entrapping method was then selected considering the amount of natural antimicrobial incorporated. The antimicrobial activity of the microcapsules was assayed by turbidimetric methods against bacteria and yeasts selected as dangerous and common microorganisms, which may be present in fresh food. Results are reported about the relationship between the amount of natural active substances released by microcapsules and the different degree of crosslinking, as well as the effects of the technological variables investigated on the kinetics of antimicrobial release.
