Fecha de publicación: | 2004 | Editor: | American Chemical Society | Citación: | Journal of Agricultural and Food Chemistry 52: 2147- 2153 (2004) | Resumen: | This paper examines changes in the structure and functionality of fish muscle proteins at frozen storage temperatures known to render very different practical storage lives (-10 and -30 °C). Apparent viscosity and dimethylamine (DMA) content showed drastic temperature-related differences during storage. Raman spectroscopy revealed the occurrence of some structural changes involving secondary and tertiary protein structures. The changes in secondary structure were quantified, showing an increase of β-sheet at the expense of α-helix structure. The νC-H stretching band near 2935 cm-1 increased in intensity, indicating denaturation of the muscle proteins through the exposure of aliphatic hydrophobic groups to the solvent. These structural changes were more pronounced at -10 °C but occurred at both storage temperatures, whereas changes in apparent viscosity and DMA only occurred in storage at -10 °C. The possible utility of these structural changes for quality assessment is discussed. | URI: | http://hdl.handle.net/10261/101283 | DOI: | 10.1021/jf034301e | Identificadores: | doi: 10.1021/jf034301e issn: 0021-8561 |
