DESENVOLVIMENTO DE FILME ANTIMICROBIANO A BASE DE EXTRATO DA PELÍCULA DO AMENDOIM (Arachis hypogaea L.)

Abstract

The study of antimicrobial compounds in plant species has generated increasing interest in the food industry, due to the increasing demand for foods that are free of synthetic preservatives by consumers. Plant species are rich in bioactive compounds with recognized properties of industrial interest, such as antioxidant and antimicrobial properties. Natural antibacterials can be found not only in leaves, branches, flowers, tubers and roots, but also in byproducts generated by the processing of fruits, vegetables, greens and grains. The objective of the present study was to develop a film with antimicrobial activity due to the incorporation of the hydroalcoholic extract of the film peanut in the most effective concentration between 70% and 80% against the strains Staphylococcus aureus (ATCC 25923) and Salmonella ssp. (ATCC 13076). Microbiological analyzes were performed by the PCA Agar technique by inoculating minidiscs by the disk-diffusion method incorporated with peanut film extract in the two concentrations. For disc control with antibiotics and discs incorporated with distilled water. The results demonstrated the antimicrobial potential of the hydroalcoholic extract of the 70% peanut film obtaining a halo of 23 mm. The film was developed with base formulation and tested in the same techniques as the extract. It obtained as result 19 mm. Even though it is a substantial result, since there are no references in the literature in this area, more research is needed to be used by the food industry.
