Estimating the possibility of isolating high quality culinary meat on the basis of fattener meatiness and colour & pH measurements using cluster analysis


The objectives of the research were to estimate the possibility of choosing the high quality culinary meat that meets the consumer expectations, on the basis of fattener meatiness, and to instrumentally measure the meat parameters: colour and pH. The study was conducted on a group of 90 fatteners descending from crossing sows of the Polish Landrance and the Polish Large White and Naïma lines with P76-PenArLan boars-hybrids. In the carcasses under analysis: meatiness, backfat thickness, and LD muscle thickness were determined, the pH level after 1, 3, 24 and 48 hours post mortem was measured, as were the following parameters: colour indicators (under the CIE L*a*b system), natural drip loss, and meat cooking yield. Furthermore, sensory quality of thermally processed meat (i.e. aroma, tone of the colour, tenderness, juiciness, and intensity of cooked meat flavour) were assessed. The results were statistically analyzed by computing simple, multivariate, and canonical correlation coefficients for the purpose of evaluating the dependencies among the parameters measured and meat characteristics analyzed. High quality culinary meat samples were isolated using a cluster analysis under the k-average method. Statistical computations were performed using a Statistica Pl 6.0 software. The results obtained prove that it is possible to apply outcomes of the assessment, conducted in meat plants, of fattener meatiness, as well as of the parameters of colour (L* and a*), and of pH48 measurements for the purpose of isolating culinary meat, as early as during the stage of producing it. The isolated meat should be characterized by a very good quality of its sensory characteristics, such as: tenderness, juiciness, and flavour, further: by a low drip loss, and a proper cooking yield being thermally treated. It was also proved that about 70% of the meat features characterizing culinary meat were determined by the carcass meatiness, colour parameters &final pH value used to assess meat.
