Extract

Visual and near infrared reflectance (VisNIR) has been identified as a possible on-line method that could discriminate some eating quality attributes of lamb (Andres et al. 2007). However, the accuracy and repeatability of this method for predicting eating quality depends on the development of an optimal sampling protocol (Shackelford et al., 2004) and of an optimal formula for the prediction model. The aims of this experiment were to identify if factors such as abattoir, carcass suspension method, ageing time and anatomical position along the Longissimus dorsi muscle can affect the characteristic of the VisNIR spectra. The information obtained from this study will allow the development an optimal protocol and prediction model.
