22 Oct 2020 --- Researchers have developed a portable device that detects how much capsaicin a pepper contains with the help of a smartphone. Thailand-based researcher Warakorn Limbut and colleagues developed the device as a simple, accurate and cheap method to quantify the capsaicin content of chili peppers.The report, which was published in the journal ACS Applied Nano Materials, may help suppliers who use capsaicin as a food additive to more easily quantify the contents within food samples.
