Botanical extracts are produced or used as ingredients in many industries, such as the cannabis industry, food and beverage, or flavours and fragrances. It is imperative that these products are safe for human consumption, and so there are regulations on the content of pesticides and trace metals. If the plant biomass is contaminated, an extract or distillate will show even higher concentrations of the pesticide, and as an expensive consequence the product may have to be discarded.
Fortunately, pesticides can be removed from extracts and oils using granular materials (adsorbents) that bind the pesticides in the extract. These adsorbents are loaded in a rotating bed reactor, whereby the extract is treated quickly and effectively. Many pesticides can be dealt with in this way.
