ResumenSeveral antimelanosis formulations were used to compare the sensorial quality loss of fresh Norway lobster during ice-chilled storage, by applying a designed grading system based on an overall sensory score (quality index). A first experiment was conducted with Norway lobster treated conventionally with a commercial sulfite-based product. A subsequent experiment was done using known concentrations of sulfites and 4-hexylresorcinol (4-HR). The presence of antimelanotics was responsible for a limited perception of changes in melanosis and yellow/greenish discolorations in the head during the first 7 days of storage, especially in the lots treated with 4-HR. Norway lobster treated with 4% commercial sulfites was considered unacceptable at around 9 days of storage. However, 4-HR-based formulations delayed the rejection point up to day 13 and 14 when using concentrations of 0.05 and 0.1% of 4-HR, respectively. © 2007, The Author(s); Journal compilation © 2007, Blackwell Publishing.
