Abstract

The purpose of this study is to analyse the impact that the extract from the sumac plant (Rhus coriaria) has on the growth of Aspergillus flavus and how much it reduces aflatoxin content in nuts. The main byproduct of A. flavus is aflatoxins, which are toxic substances that can cause serious health issues, such as cancer, and negatively impact the economy. Current treatments for fungus are not very effective, so natural alternatives need to be explored. Sumac's multiple properties – antimicrobial/antifungal activity and antioxidant properties, combined with its high polyphenolic content (mainly tannin and flavonoid substances) – produce a potential solution. The efficacy of various concentrations (0.5%, 1%, & 2%) of sumac extract to inhibit the growth of A. flavus and decrease the amount of aflatoxin produced due to A. flavus in both food products were assessed through laboratory experiments. The results of the study indicate that the use of 2% sumac extract as an antifungal agent provided a greater than 88.3% reduction in the number of fungal colonies and more than 91.5% reduction in aflatoxin levels; both of these levels of inhibition are equivalent to those obtained from the synthetic compound sodium benzoate. Nutrition quality will also be preserved, shelf life will be extended, and aflatoxin levels will be decreased with the use of sumac extract as a food preservative. Additionally, researchers should focus on determining improved methods of applying sumac, as well as researching the shelf life of sumac and how effectively sumac can complement other naturally occurring antifungal compounds. This research project advances the creation of sustainable food preservation approaches that use eco-friendly methods.
