Abstract (EN):
Two shrimp species were sampled in different seasons and locations on Portuguese coast. Their fatty acid content and 28 essential, probably essential and potentially toxic/non-essential elements were quantified. A 100 g serving of shrimp muscle from the Portuguese coast provides 78 % of the recommended daily intake. Both species presented low omega-6/omega-3 ratio, 0.15 for P. serratus and 0.23 for P. varians, respectively. The quality indices presented also good values for shrimp samples, hypocholestemlemic/hypercholesterolemic ratio (HH) was 2.60 for P. serratus and 2.55 for P.varians. The index of thrombogenicity (IT) were 0.24 and 0.25 for P. serratus and P. varians, respectively and index of atherogenicity (IA) was 0.41 and 0.43 for P. serratus and P. varians, respectively. The Mg, Na, K, Ca, I, Cr, Cu and Se in shrimp samples analyzed can provide more than 5 % of the Recommended Dietary Allowance (RDA)/ Adequate Intake (AI). The best nutritional Ca/Mg ratio was found in P. serratus (1.7). Portuguese shrimp has proven to be a good dietary source of EPA, DHA and some essential elements, also Target Hazard Quotient (THQ) and risk-benefit evaluation shown that there is no significant danger associated with the consumption of Portuguese shrimp.
