Les caractéristiques physico-chimiques de caviars d'esturgeons d'élevage et sauvages

The chimical and biochemical composition of the caviar was measured on 28 specimens from wild caught (Huso huso, Acipenser gueldenstaedti, A. stellatus and Polyodon spathula) and seven of farmed animals (A. baeri, A. stellatus and P. spathula). The results include grain size, protein and fat content, fatty acid composition of triglycerides and phospholipides, as well as the concentrations of relevant heavy metals and chlorinated hydrocarbons.
