Qualidade e vida de prateleira da gônada do bivalve pata de leão, transportado e armazenado inteiramente em refrigeração

Abstract

The effect of refrigerated 48h transport and 4 days storage on the quality and shelf life of the whole lion’s paw scallop Nodipecten subnodosus gonad was evaluated. Proximal composition, adenosine 5´triphosphate (ATP) and related products, K-value, total volatile bases (TVB-N), trimethylamine (TMA-N), pH, fatty acid profle and microbiological analyses were quantifed. Gonad holds a signifcant composition of essential fatty acids while levels of gonadal ATP were initially low; moreover, K-value of the gonad remained constant. With respect to TVB-N and TMA-N, only the former exceeded allowed limits. The pH level showed no signifcant variation during storage and, despite the high level of TVB-N, according to the TMA-N as well as microbiological analyses it was demonstrated innocuity after 4 days under the transportation and storage conditions utilized.
