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.

A beta attenuation method has been developed for measuring void fractions which is sensitive enough for use during local boiling. Comparisons are made with gamma attenuation methods, the effects of preferential void location are demonstrated, and typical void fractions measured during forced-convection, subcooled boiling of water are presented. The technique has been found to be readily applicable to the accurate determination of void fractions during either saturated or subcooled boiling of water and organic liquids.
