Effect of Mangosteen (Garcinia mangostana L.) Pericarp Extract on the Different Carriers for Antioxidant Active Packaging Films

Abstract

Active packaging with the addition of natural antioxidant compounds has been developed as a potential alternative to plastic-based materials to protect food products from environmental damages. This study investigated the effect of mangosteen (Garcinia mangostana L.) pericarp extract (MPE) as a natural antioxidant on the physicochemical properties of fish gelatin (FG), soy protein isolates (SPI), and corn starch (CS) films. MPE at different concentrations (0, 1, 3, and 5%, w/v) were added into each of the film-forming solutions (FFS) and film without the active compound was considered as a control. MPE increased the water vapor permeability and reduced the mechanical properties of the films. In addition, protein-based films resulted in better mechanical properties compared to starch-based films. However, corn starch films possessed good water resistance than protein-based films. SPI film with 5% MPE expressed the highest value of DPPH-scavenging activity (92.67%) followed by CS (88.43%) and FG (61.51%) films. In conclusion, MPE added in the FFS has improved the functional properties of biodegradable films with soy protein-based films exhibited the highest antioxidant capacity and, therefore, could be a promising natural antioxidant to be incorporated in packaging material as active film.

Novel α-Mangostin Derivatives from Mangosteen (Garcinia mangostana L.) Peel Extract with Antioxidant and Anticancer Potential

“…e soft and juicy white part inside mangosteen is mainly consumed fresh as dessert. In contrast, the mangosteen peels have been utilized extensively in traditional medicine for treating several illnesses, including skin infection, dysentery, trauma, abdominal pain, and wound infection, as well as cancer treatment [20][21][22].…”
