摘要
Summary In this study, the influence of ripening with Penicillium roqueforti on texture, microstructure, protein structure, water mobility and volatile flavour compounds of chicken breast meat was investigated. Scanning electron microscopy ( SEM ) and transmission electron microscope ( TEM ) images showed that the granule formed and chicken myofibril fractured after ripening. Reduction in α‐helix and increases in β‐sheet structure content accompanied by decrease in hardness and springiness and increase in gumminess were found in ripened chicken breast meat. Low field nuclear magnetic resonance ( LF ‐ NMR ) revealed that increasing intra‐myofibrillar water and decreasing extra‐myofibrillar water resulted in the higher water‐holding capacity after ripening with P. roqueforti . In addition, chicken breast meat ripened with P. roqueforti contained more volatile flavour compounds, in particular aldehydes.
