In this paper, the adding-double (AD) method and Monte Carlo (MC) method were compared for demonstrating the accuracy of the AD method. The results of the comparison indicated that the error of the AD method relative to the MC method was less than 3%. The running time of the AD method was only several seconds, which was less than the running time of MC method. And the outputs of the Inverse adding-double (IAD) method were consistent with the original data, which were the input of the MC program. After checking the validity of the IAD method, it was used to obtain the optical properties of the pig muscle with different concentrations of Sudan. The results indicated that the absorption and reduced scattering properties were dependent on the wavelength, and at 700 nm there were significant increase in the absorption and reduced scattering values for the samples with Sudan compared to the normal sample.
