Influence of varied processing methods on the antioxidant capacity, antibacterial activity, and bioavailability of Iranian black, oolong, and green leafy teas.

In this study, the impact of various tea preparation techniques on the content of bioactive compounds, antioxidant capacity, antibacterial properties, and polyphenol bioavailability in green, black, and oolong tea infusions was examined. The findings demonstrated that the fermentation process significantly influences the levels of bioactive compounds, with green tea infusions exhibiting the highest, and black tea the lowest, content of phenolic compounds. A positive correlation was observed between the content of the phenolic compound and both antioxidant and antibacterial activities.

Comparative study of physiochemical properties in Iranian multi-floral honeys: Local vs. commercial varieties.

Iran, a leading honey-producing country, faces challenges in honey exports. This study aimed to evaluate the melissopalynological and physicochemical characteristics of local honeys belonging to Iranian flora, and compare them with Iranian commercial honeys. For this purpose, seven local honey samples were collected from Iran's renowned floristic regions, alongside seven commercial multi-floral honeys from a supermarket.
