MINERAL SAFETY INDEX AND FUNCTIONAL PROERTY OF THE STOMATOPOD SHRIMP (SQUILLA ACULEATA HOLTHUIS, 1959) (CRUSTACEA: STOMATOPODA)

Résumé

The study was conducted to analyze the mineral composition, safety ratio and functional properties of the cephalothorax and abdomen (fillet) of the stomatopod shrimp, Squilla aculeata. The mineral content, expressed in mg 100g-1, revealed distinctive patterns in the two body parts. The cephalothorax exhibited higher concentrations of Ca, P, Mg, Na, K, Fe, and Mn compared to the abdomen. Notably, the mineral safety index (MSI) calculated for each mineral indicated potential
mineral overload in both body parts, excluding sodium. The MSI values for Ca, Mg, P, and Na were compared against standard values. All minerals, except sodium, exhibited negative percentage differences, suggesting elevated concentrations beyond the recommended levels. The extent of these differences ranged from -1250.27 to 60.29 for cephalothorax and -706.2 to 82.82 for the abdomen, emphasizing the potential health risks associated with the consumption of S. aculeata. Furthermore, the functional properties of the stomatopod shrimp, revealing significant variations between the cephalothorax and abdomen. The cephalothorax demonstrated higher values in water absorption
capacity (WAC), oil absorption capacity (OAC), emulsion stability, foam stability, solubility, packed bulk density, loose bulk density, specific gravity, and emulsion capacity. Conversely, the abdomen exhibited superior foam capacity, swelling power, and dispersibility. In conclusion, this study contributes valuable insights into the mineral safety/composition and functional properties of different body parts of S. aculeata. The findings underscore the importance of considering both
nutritional content and functional characteristics when evaluating the suitability of stomatopod shrimp for consumption and industrial applications.
