Tanngoen et al.: Evaluation of AM-FFGs Against Acne-causing bacteriaIn this study, α-mangostin, extracted from mangosteen peel, was developed in to a topical film-forming gel antiacne preparation using different film-forming polymers as carriers. The physicochemical properties and α-mangostin incorporation efficiency were evaluated. In vitro permeation of α-mangostin-loaded film-forming gels, antibacterial activity against Propionibacterium acnes and Staphylococcus aureus were examined. The optimal formulations were viscous gels, which could convert into a dry film within 30 min after application. The films were transparent, flexible and easy to peel off. Scanning electron micrographs of the α-mangostin-loaded film-forming gels revealed a rough surface with an interior porous structure while blank film-forming gels showed smooth and compact morphology. The high α-mangostin incorporation efficiency up to 96 % was achieved. In vitro permeation studies showed a biphasic permeation profile with a fast permeation characteristic within 30 min followed by a slow permeation up to 8 h. α-Mangostinloaded film-forming gels demonstrated efficient antibacterial activities against P. acnes and S. aureus. Moreover, α-mangostin-loaded film-forming gels showed good physicochemical stability during storage at 4º for 6 mo. In summary, the developed α-mangostin-loaded film-forming gels are good candidates for topical antiacne treatments.

To develop a value-added product, we used the under-utilised seaweed Undaria pinnatifida as a source material for the fabrication of a biodegradable film by extracting U. pinnatifida protein (UPP). UPP/gelatine composite films with different constituent ratios were prepared. In addition, the UPP/gelatine composite films containing vanillin (0.05%, 0.1% and 0.5%) were prepared as antimicrobial packaging material. To evaluate the utility of the UPP composite film containing 0.5% vanillin as food packaging material, smoked chicken breast samples inoculated with Escherichia coli were packed with the film and stored at 4°C for 10 days. It was observed that packaging of smoked chicken breast with the UPP composite film containing vanillin decreased the population of the inoculated E. coli by 1.12 log CFU g À1 compared with that in the control sample. Thus, the UPP/gelatine composite film with added vanillin can be utilised as a packaging material for smoked chicken breast.

“…the independent variables used in the formulation of films were sorbitol and gallic acid concentration, where the range of these variables was based on previous studies of antioxidant properties and solubilities. Sorbitol concentration was defined as a factor with five levels (X 1 : 1, 3, 5, 7, 9 wt%) according to previous works reported negative effect on final properties in films without plasticizers [10,12]. On the other hand, gallic acid composition is a factor whose three levels (X 2 : 0.50, 0.75, 1 wt%) represent the best antioxidant activity according to preliminary assays.…”

“…On the other hand, the addition of phenolic compounds or natural extracts with antimicrobial and antioxidant activity in a chitosan matrix enhances its physical properties from non-covalent interactions such as hydrogen bonds. Zhang et al [12] have demonstrated that vanillin acts as a cross-linking agent in the formation of chitosan matrix. In addition, the presence of phenolic compound such as green tea extract improves mechanical and vapor barrier properties as well as antioxidant properties of the resulting chitosan based films [13].…”

The interest in the development of biodegradable films is increasing, which is related to the wide availability of resources and methods of synthesis to generate them. For this reason, in this study, the preparation of films containing chitosan, sorbitol and gallic acid this study was proposed. The incorporation of natural antioxidants into films modifies their structure and provides new functionality to them. In order to determine the optimal content of sorbitol and gallic acid in the formulation of the chitosan films to obtain the highest antioxidant capacity and the best mechanical properties, an experimental design based on a two-factor Doehlert model was used. The optimum condition of film synthesis was obtained when a mixture of 1 wt chitosan, 3.62 wt% of sorbitol and 1 wt% of gallic acid was performed. The properties studied were experimentally evaluated at this optimal point and compared with the model predictions, showing good results. It proved to be a promising material to be successfully used as packaging material.
