Commercially available white, pale yellow and dark yellow coconut oil samples were
obtained from eight locations in Sri Lanka and their refractive indices were measured at
room temperature 28 C in the wavelength range of 410− 630 nm using refractometric
techniques. Experimental data were fitted to Caushy dispersion formula with a high accuracy
(r2= 0.98). The refractive index for a given wavelength showed the variation,
