Background and Objectives: Kebab loghmeh is one of the most popular meat products in Iran. Quantitative assessment of the red meats is critical as the most important factor in authentication of this meat product. Other methods of adulteration tracing do not include enough efficiency to quantitatively assess quantities of the red meats in final products. Therefore, the objective of the current study was to quantitatively assess red meats in Kebab loghmeh samples using Fourier transform infrared (FTIR) method and chemometric methods.
Materials & Methods: Samples of industrial Kebab loghmeh containing 70 and 90% of red meats from three various brands were purchased from the local markets and standard formula samples were prepared in meat product factories (total sample number of 36). All samples were transferred to the laboratory under cold conditions. Data from FTIR were analyzed using PCA, PLS-DA and SIMCA methods as chemometric methods.
Results: Results of multiple linear regression and chemometric methods with high determination coefficient (R2 = 0.9999) showed that 67% of the samples did not included information provided on the labels.
Conclusion: Analysis of FTIR data using chemometric methods is appropriate for the quantification of red meats in kebab loghmeh samples. |
