Einfluß von Eis- und Tiefgefrierlagerung/Auftauen auf die Länge von Seefischfilets

摘要

The objective was to study the influence of biological and processing conditions on the evaluation of a conversion factor between fillet length and fish size. This paper presents changes of the length and weight of skinless fillets from various marine fish species in relation to the ice storage time and to the deep freezing / thawing process. The biochemical changes during rigor mortis lead to considerable reduction in length of skinless fillets during ice storage and deep freezing / thawing of fillet blocks. The investigations were undertaken during various cruises of the FFS „Walther Herwig III“.
