Description
Summary:The objective of this study is to determine the effect of the ageing time on the quality characteristics of yearling calf meat under vacuum. Ninety-six Rubia Gallega yearling calves were used. Samples of the Longissimus thoracis at 1 day post slaughter as a control, and vacuum-packaged for 7, 14 and 21 days were analysed. Colour (lightness, L*, redness, a*, yellowness, b*, hue, H^sup o^, chroma, C*, and pigment concentration), water-holding capacity (expressible juice and cooking losses), pH and toughness were measured. The statistical analysis showed an increase in a*, b*, H^sup o^ and C* and a decrease in expressible juice, cooking losses and toughness as the ageing time increased. Discriminant analysis divided the samples into two groups; i.e., 1-day post-slaughter samples and vacuum-packaged samples. Considering vacuum-packaged samples only, canonical discriminant analysis separated the long-ageing samples (21 days) from the short-ageing samples (7 days).[PUBLICATION ABSTRACT]
