Biodegradable films of arrowroot starch were incorporated with floral extract of Tabebuia impetiginosa and copper sulfate and determined to the physical, physicochemical, biodegradability and antibacterial properties. The films were produced from arrowroot starch with different concentrations of glycerol, floral extract and copper sulfate solution. Thickness, humidity, solubility, biodegradability, water vapor colorimetry, color density, transparency, FT-IR and antibacterial activity tests were performed for Escherichia coli, Staphylococcus aureus, Salmonella serovar Thyphymurium and serovar Enteritidis. The films had a thickness between 0.23-0.33 mm, humidity between 8.53-12.22%, biodegradability between 88.98-100%, water vapor between 255.79-433.57 g m2 day, L* between 4.77-22.36; a* between -1.20 to 0.30; b* between -1.89 to 0.13; color density between -0.09 to 0.180; maximum transparency of 80%, inhibition activity between 9.13-26.26 mm for E. coli, 5.83-24.14 mm for S. aureus, 13-42-19.39 mm for S. serovar Thyphymurium, and 22.14-26.89 mm for S. serovar Enteritidis. The arrowroot biodegradable films incorporated with floral extract of Tabebuia impetiginosa and copper sulfate showed good physical, physicochemical, biodegradability and potential antibacterial activity.

The functional properties of biofilms can vary according to the biopolymer used as the raw material; thus, in the search for alternative sources for preparation of biodegradable films, fruits and vegetables have been used to extract compounds of interest with applications in the food industry. The objective of this work was to obtain and characterize bioactive films based on pectin extracted from the epicarps (skin) of the fruit. The genipap (Genipa americana), red pitaya (Hylocereus polyrhizus) and star fruit (Averrhoa carambola) were collected, washed, pulped and dried at 50 °C for 24 h, and their epicarps were ground and subjected to pectin extraction using the casting method. The films were characterized as to their visual appearance, moisture, pH, water solubility and antioxidant activity. The pectin-based films of G. americana and H. polyrhizus showed a yellowish color, while A. carambola was dark brown. The highest pectin yield (29%) and moisture content (13.9%) were obtained from the H. polyrhizus film, while A. carambola showed the highest solubility in water (98.6%) and had the highest pH (3.9). Additionally, the film based on A. carambola showed greater antioxidant potential against ABTS (30.5%) and DPPH (34%), as well as greater reducing power (0.262 absorbance at 750 nm) and content of total phenolic compounds (553 mg GAE/100 g), whereas H. polyrhizus had a higher percentage of chelating ability (27%). The physicochemical characteristics and bioactive properties exhibited make the film formulation a viable alternative for the food industry.

O trabalho teve por objetivo avaliar as características poliméricas do biofilme a partir do resíduo do fruto de Citrullus lanatus. O biopolímero foi produzido a partir de uma suspensão aquosa farinácea do albedo e avaliado quanto às características físico-químicas, antioxidantes, mecânicas e por análises em microscopia óptica e eletrônica por varredura. O biofilme do resíduo de melancia apresentou importantes resultados nos testes físico-químicos, mecânicos e de atividade antioxidante, importante quantitativo de fenóis totais e boa eficiência nas características estruturais. Este novo biopolímero a partir do resíduo de melancia poderá ser aplicado no desenvolvimento de embalagens biodegradáveis, bem como no revestimento de salames defumados na indústria alimentícia.
