Abstract FT-NIR is concluded to work well when analyzing pure tallox, regardless of the process conditions and the degree of purity, but reveals difficulties when working on mixtures. In contrast, PCR and immunoassays show outstanding sensitivity, because tallow can even be detected when mixed with other fats at a low ration. However, both methods were found to score poorly in the case of premier jus, due to its extemely low content of insoluble impurities.
