Verso un utilizzo sostenibile della quinoa: Studio dell'attiVità antimicrobica dell'estratto acquoso di scarti

this study is aimed at the implementation of sustainability and eco-innovation in the Quinoa productive process verging toward "zero waste economy" in which waste is used as raw material for new applications. for this purpose the protective activity expressed by pericarp removed from the seed using the pearling process and the antimicrobial activity of aqueous extract from quinoa pearling by-product were evaluated. in detail, the antimicrobial activity in plate was assessed by agar well diffusion assay and the Minimum inhibitory Concentration (MiC) vs gram negative (P. fluorescens dSMZ 50009T and P. fragi dSMZ 3456T) gram positive (Listeria innocua and Bacillus subtilis) and vs P1 Fusarium spp. was determined. the aqueous extract highlighting a strong inhibitory activity against all the assayed strains, represents a promising candidate for antimicrobial strategies aimed at the control of microorganisms.
