Analysis of the Mineral Composition of Louisiana Wild Caught Shrimp by ICP-OES and Classification of Geographical Origin

Nationwide, seafood consumers are paying close attention to their seafood options and demanding transparency on point of origin. Recent studies have shown that shrimp can reflect the mineral content of the waters from which they are harvested. Mineral analysis was conducted using inductively coupled plasma optical emission spectrometry on the tail muscle from each coastal group and imported farmed raised samples. Analysis of variance was used to detect differences among catch locations and seasons along the Louisiana coast, as well as differences in the mineral profile of farm raised imported shrimp. Multivariate analysis of variance and descriptive analysis was used to evaluate which minerals contributed the greatest variance to the mineral profiles (Al, P, Fe, Mg, K, Na, Cu, Zn, and Ca) of Louisiana shrimp from over 100 sampling sights. The minerals Ca, and to a lesser extent Zn and Cu were identified as the most discriminating minerals (canonical correlation=0.8269, 0.3929, and 0.5547, respectively). Based on predictive discriminant analysis using cross validation of nine minerals, the catch zones of Louisiana wild caught shrimp could be predicted with an overall accuracy of 86.93% and specifically into the correct zones 1, 2, and 4 with 73.68%, 74.85%, and 95.40% accuracy, respectively.
