Edible Bird’S Nest

Edible bird's nest (EBN) is a high-value health-promoting tonic from swiftlets. However, cheap House-EBN is usually masqueraded as expensive Cave-EBN for profiteering. Efficient scientific means are required to trace Cave-EBN. After microwave digestion of EBN lyophilizing powder, its mineral element compositions were examined by using inductively coupled plasma-mass spectrometry (ICP-MS). Influences of two key factors, production environment and country, on the distribution of 21 elements were analyzed. Linear Discriminant Analysis (LDA) coupled with leave-one out cross validation was applied for modeling. Classifier generalization performance was assessed by the Confusion Matrix approach. ICP-MS identified the presence of 21 macro and micro elements with contributions of 99.65% and 0.35%, respectively. A two-way ANOVA established that B, Na, K, Ca, Mn, Cu, Sr, and Cd were the production-environment-specific elements. Among four different combinations based on three potential variables (Ca, Na, and Sr), Na/Ca was identified as the best among them having 100% specificity on tracing Cave-EBN. In conclusion, EBN was a good mineral element source. The methodology of integration of ICP-MS with chemo-metrics proved to be a powerful tool for tracing Cave-EBN.

<p>The article demonstrates the importance of using a suitable approach to compensate for dead time relate count losses (a certain measurement artefact) whenever short, but potentially strong transient signals are to be analysed using inductively coupled plasma mass spectrometry (ICP-MS). Findings strongly support the theory that inadequate time resolution, and therefore insufficient compensation for these count losses, is one of the main reasons for size underestimation observed when analysing inorganic nanoparticles using ICP-MS, a topic still controversially discussed.</p>
