Encapsulation of Flavours and Fragrances into Polymeric Capsules and Cyclodextrins Inclusion Complexes: An Update

Abstract

Flavours and fragrances are volatile compounds of large interest for different applications. Due to their high tendency of evaporation and, in most cases, poor chemical stability, these compounds need to be encapsulated for handling and industrial processing. Encapsulation, indeed, resulted in being effective at overcoming the main concerns related to volatile compound manipulation, and several industrial products contain flavours and fragrances in an encapsulated form for the final usage of customers. Although several organic or inorganic materials have been investigated for the production of coated micro- or nanosystems intended for the encapsulation of fragrances and flavours, polymeric coating, leading to the formation of micro- or nanocapsules with a core-shell architecture, as well as a molecular inclusion complexation with cyclodextrins, are still the most used. The present review aims to summarise the recent literature about the encapsulation of fragrances and flavours into polymeric micro- or nanocapsules or inclusion complexes with cyclodextrins, with a focus on methods for micro/nanoencapsulation and applications in the different technological fields, including the textile, cosmetic, food and paper industries.

Synthesis of Poly(Ethylene Brassylate-Co-squaric Acid) as Potential Essential Oil Carrier

“…As a result, numerous research studies have been developed to ensure protective covering of essential oils and their complex preparation to successfully manifest their biological properties. Along with natural polymers, the synthetic macromolecular compounds present an alternative to the possibilities of encapsulating essential oils in order to maintain their biological activities, for example, their antioxidant, antibacterial, antiviral, antifungal, anticancer, antidiabetic, and anti-inflammatory properties [ 1 , 2 , 3 , 4 ]. A challenge for the use of EOs is represented by the possibilities of their encapsulation with the maintenance of the biological applications in an appropriate polymer structure.…”

Innovative Delivery Systems Loaded with Plant Bioactive Ingredients: Formulation Approaches and Applications

“…Systems that have been used so far for the controlled release of various bioactive compounds include liposomes [ 26 , 27 ], nanoemulsions [ 28 , 29 ], polymers, etc. [ 30 , 31 , 32 ].…”

Production of Large-Ring Cyclodextrins by Amylomaltases

“…G-825-6 could produce mainly CD8-CD12 [5]. Although CD6-CD8 are widely used in food, cosmetic, and pharmaceutical industries to stabilize or enhance solubility of the guest molecules [6][7][8][9], LR-CD applications are limited due to small quantities obtained during synthesis and lack of efficient separation techniques.…”
