Quality characteristics and consumer acceptance of diploid and triploid cold smoked Atlantic salmon reared at 5, 10 and 15 C
This study determined the processing characteristics, textural and colorimetric properties, NaCl content and consumer's acceptability of dry salted cold smoked triploid Atlantic salmon (average weight of 1.6 ± 0.3 kg) reared at different temperatures (5, 10 and 15 °C). As a reference, diploid s...
