Abstract
- Focusing on the high dispersion of stable isotope ratios (δ13C, δ15N, δ18O, δ2H) in edible bird's nest (EBN), a robust method was developed to simultaneously discriminate and quantify three types of substances (sialic acid, egg white and food gums) added separately into EBN. Results showed that by establishing a data processing formula to improve cohesion of the samples' isotope ratios, a discriminant formula was achieved with an accuracy ranging from 88% to 99%. With the three adulterated references, discriminant was set up by the calculated Euclidean distance with prediction accuracy ranged from 95.80% to 99.97%. Additionally, three equations were building-up to quantity the content of those adulterated substances of EBN, with satisfactory relative standard deviations and within the range from 1.34% to 6.31% (n = 6). By applying the developed methods, two out of the twelve samples were found to adulterate 3.9% sialic acid and 2.9% egg white respectively. • The method is used to simultaneously discriminate and quantify the adulterant of EBN. • A discriminant formula is achieved with high accuracy by cohesion isotope ratios. • The method is built by the optimized Euclidean distance with good predictive ability. • Quantification of adulterants exist a good linearity and fewer detection error. • The method is successfully used to identify real sample with a high accuracy.
