Antioxidant and antimicrobial activities of ginseng extract (GE), ferulic acid (FA) and fermented noni juice powder (FNJP)

Ginseng extract (GE), ferulic acid (≥ 99%) (FA), and a fermented noni juice powder (FNJP), were investigated for their antioxidant and antimicrobial activities in vitro. For antioxidant analysis, the capacity of the three extracts (GE, FA and FNJP) to inhibit polyphenol oxidase from three vegetable matrices (potato, apple or mushroom) and the peroxidation prevention of three types fats (sunflower oil, olive oil and butter) were studied (AGRIMAX_IA_EXTRACTS_AOX_PPO_IRTA_05112021; AGRIMAX_IA_EXTRACTS_AOX_PEROX_IRTA_05112021). The extracts’ antimicrobial activity was studied on thirteen bacterial strains using the disk diffusion assay and the microdilution assay (AGRIMAX_IA_GE_AM_IRTA_05112021; AGRIMAX_IA_FA_AM_IRTA_05112021; AGRIMAX_IA_FNJP_AM_IRTA_05112021; AGRIMAX_IA_EXTRACTS_AM_MIC_IRTA_05112021.). The results obtained suggest the potential of GE, FA and FNJP for its further application in food industries. The data were obtained in the microbiology laboratory of IRTA Fruitcentre (Lleida, Catalonia). These data are the result of the average of 3 replicates (± standard deviation, sd) where the antioxidant and antimicrobial effect of ginseng extract (GE), ferulic acid (FA) and FNJP are studied. The results of this research are part of the AGRIMAX H2020 project.
