Note. Effect of a cryoprotectant agent (sodium tripolyphosphate) on hake slices preserved in modified atmosphere packaging/Nota. Efecto de un crioprotector (tripolyphosphate sódico) sobre merluza en rodajas envasada en atmósfera modificada

Abstract

Fresh hake slices packed in a modified atmosphere with a cryoprotectant agent (sodium tripolyphosphate) and under chilling conditions showed a reduction of exudate production. However, no improvement was achieved in microbiological and chemical parameters used as quality control factors compared with those packed only in a modified atmosphere (MAP). Thus final results concluded that the shelf-life of fresh hake slices packed using MAP and sodium tripolyphosphate was shorter than the shelf-life of fresh hake slices packed using only MAP.
