What’s in your Dubai chocolate? Nuclear scientists test pistachios for toxins
For the uninitiated, Dubai chocolate is a candy bar filled with pistachio and tahini cream and crispy pastry recently popularized by social media influencers. While it’s easy to dismiss as a viral craze now past its peak, the nutty green confection has spiked global pistachio demand, and growers and processors are ramping up production. That means more pistachios need to be tested for aflatoxins—a byproduct of a common crop mold.

The feasibility of purifying irradiation-degraded Purex-type solvent by distillation was indicated by laboratory scale studies. Direct fractional distillation does not appear to be feasible; however, flash distillation of the mixture into separate TBP and Amsco components and subsequent fractional distillation of each component can be performed in a trouble-free manner. The results of this work indicate that a washing operation and several flash distillations should suffice for purification of solvent irradiated up to 120 w-hr/liter.
