Abstract
AbstractThe present investigation reports the extent of fungal contamination in stored samples of Arachis hypogaea and efficacy of seed and leaf essential oils (EOs) of Anethum graveolens against isolated fungi, aflatoxin production and their antioxidant efficacy. Twelve fungal species were found associated with A. hypogaea along with toxigenic isolates of Aspergillus flavus. The minimum concentrations for inhibition of growth of toxigenic strain of A. flavus (LHPFah‐6) and aflatoxin production were found to be 1.25 and 1.0 μL/mL for seed oil and 7.0 and 6.0 μL/mL for leaf oil. The EOs exhibited broad antifungal spectrum. The seed and leaf EOs also exhibited free radical‐scavenging activity having IC50 value 12.4 and 24.3 μL/mL, respectively. In addition, the EOs showed nonphytotoxic nature on radicle growth of A. hypogaea. The study recommends A. graveolens seed EO as a potent antifungal, aflatoxin inhibitor and free radical‐neutralizing agent to enhance shelf life of food items.Practical ApplicationsBecause of high efficacy as antifungal, aflatoxin inhibitor and antioxidant, as well as due to nonphytotoxic nature, the A. graveolens seed essential oil may attract the food industries related to food safety for its large‐scale trial to recommend its possible application as an eco‐friendly plant‐based alternative of synthetic preservatives during postharvest processing of food items.
