Abstract
Coffee is among one of the most consumed beverages in the world and is also susceptible to contamination by mycotoxins and heavy metals. In this study, the concentration of aflatoxins and selected heavy metals were quantified in roasted and ground coffee bean samples from markets in Pakistan. Furthermore, an activated carbon-based filter was tested for removal of aflatoxins and heavy metals from the coffee. The impact of the filtration system on the caffeine content and sensory properties of coffee was also measured. Findings of this study indicated that aflatoxins and heavy metals especially lead are prevalent in coffee samples available in the markets of Pakistan, above the maximum allowable limits. Furthermore, activated carbon has significant potential to act as a filter for the removal of aflatoxins and heavy metals in coffee.
