Description
  • The colour of minced meat is a very important parameter to evaluate. The intensity of the meat product's red colour is not affected only by the haem pigment concentration, the amount and composition of fat, technological processes, but also by the storage conditions. The complicated structure of minced meat (a rough chopped meat product) with separate muscle and fat particles makes it very difficult to measure and evaluate these colour changes using a classical reflectance spectrophotometry method. Therefore video image analysis is used to divide the minced meat into precise parts and to measure and evaluate the colour of the red muscle particles applying a suitable threshold. Colour changes (redness a* decrease) during the storage of minced meat are influenced by the concentration of rosemary extract. These rosemary antioxidants influenced also lipid oxidation; at higher concentration of the extract a carry-through effect is supposed. This study of a commercial preparative of rosemary extract shows the possibilities for the usage of rosemary (extract) in the meat industry as an effective natural antioxidant, which is a good alternative to chemical additives.
