Background & Objectives: Regarding to economic value ​​of meat, use of unauthorized animal tissue is possible in meat products. Therefore, the present study was performed to determine the efficacy of histological examination in qualitative and quantitative detection of minced meat fraud by means of mixing avian skin and adipose tissues.  

Methods: In this experimental study, the avian skin and adipose tissue samples of 5, 10, 15, and 20% in minced meat were prepared individually. Then sampling and histological examinations were performed. The mean proportions of the surface areas of avian skin and adipose tissues were calculated at five different points of each section and statistical analysis was done by ANOVA.

Results: The avian skin and adipose tissues were observed in all samples in different percentages. The quantitative results of histological examination of minced meat samples containing 5, 10, 15 and 20% of avian skin and adipose tissues revealed the respective efficacy of this technique to be 8.48 ± 6.15, 11.91 ± 7.32, 16.96 ± 7.93, and 20.54 ± 8.15%  for avian skin tissue and 2.92±3.69, 4.24±5.18, 7.21±7.02, and 9.8±10.16 for adipose tissue  (p<0.05).

Conclusion: The present study showed that histological technique has ability to determine the quality and quantity of avian skin mixing values in minced meat products. Although this method showed an acceptable adequacy in qualitative determination of the adipose tissue, however, it has no sufficient adequacy in assessing the quantity of this tissue probably due to dissolution of fat in xylene during the staining process.

Keywords: Avian Skin, Adipose tissue, Minced Meat, Histology, Food Fraud.
