• The concentration of fluoride in Antarctic krill (Euphausia superb) was investigated using a coaxial probe method based on dielectric properties in the 0.3–10 GHz frequency range. A quantitative relationship between the fluoride concentration in the aqueous solution and the dielectric loss at 0.3 GHz was also established with a regression coefficient over 0.98. The concentrations of fluoride in fresh and dried krill samples with different krill positions, such as shell and meat, were determined. The detected value agrees well with that determined using other methods, such as fluoride ion‐selective electrode (ISE) and potassium permanganate titration (PPT). The fluoride concentrations in fresh krill were 0.0127, 0.0133, and 0.0152 mg/mL using dielectric spectroscopy, PPT, and ISE, respectively. These results show that the proposed dielectric loss technique is suitable and effective for determining fluoride content in Antarctic krill.
