Identification of meat of slaughtered animals by express methods

Identification of meat of slaughtered animals (beef, pork, mutton, meat of goat) using express methods of colour intensity (probability of method 99,0–99,6%) by pigment content (probability of method 98,5–99,6%) by photometric methods and the elastin content (probability of method 98.9% probability) were determined. The optical colour intensity of the beef obtained from animals aged 24–36 months was 2,468±0,012 B by the express method of beef, and veal obtained from animals aged 6–8 months was 2,186±0,023 B; pork obtained from animals aged 12–14 months – 2,123±0,015 B, and pork obtained from animals aged 8–10 months – 1,871±0,019 B. The optical colour intensity of mutton colour obtained from animals aged 10 months was 2,25±0,064 B, 12 months old – 3,742±0,118 B, 14 months old – 4,061±0,124 B. The optical colour intensity of the meat of goat colour obtained from animals aged 8 months was 2.249±0.034 B, 10 months old – 2.578±0.019 B, 12 months old – 2.635±0.021 B. The total pigment content by the developed express method was: in beef obtained from animals aged 24–36 months – 1,893±0,043 B, veal, from animals aged 6–8 months – 2,186±0,023 B; pork obtained from animals aged 12–14 months – 1,275±0,025 B, pork from animals aged 8–10 months – 0,872±0,019 B; in lamb obtained from animals aged 10 months – 1,245±0,035 B, from animals aged 12 months. – 1,432±0,041 B, from animals aged 14 months – 1.625±0.031 B; goat obtained from animals aged 8 – 0,968±0,015 B, from animals aged 10 months – 1,076±0,038 B, from animals 12 months of age – 1,143±0,034 B. Optical density indicators for the total pigments content had a high probability of 1.97 times less (p≤0.001) compared to those of beef, and pork obtained from animals aged 8–10 months also had a high probability of 1.46 times less (p≤0.001) compared with the indices of pork obtained from animals 12–14 months. The optical density indicators for the total pigment content of mutton obtained from animals of 14 months and 12 months had a probability of 1.31 (p≤0.01) and 1.15 times (p≤0.001), respectively, higher than those of mutton obtained from animals aged 10 months. And the optical density indices for the total pigment content in meat of goat obtained from animals 12 months and 10 months were respectively 1.18 (p≤0.001) and 1.11 times (p≤0.05) higher than the values meat of goat obtained from animals aged 8 months. The highest content of elastin by the express method was found in beef – 2.12±0.04% (p≤0.001), which is 1.33 times more likely than the normative index, in meat of goat – 1.92±0.03 % (p≤0.001), which is 1.20 times more likely than the normative index and meat of mutton – 1.92±0.03 % (p≤0.001), which is 1.09 times significantly higher than the normative index (1.60±0.01 %). And in pork this indicator was probably the lowest and was 0.82±0.05% (p≤0.001), which is 1.95 times less than the normative index. Therefore, the established indicators of colour intensity, total pigment content, elastin content of slaughtered animals by express methods can be used for veterinary-sanitary inspection of meat of slaughtered animals – beef, pork, mutton and meat of goat to confirm their quality and safety, also species and age affiliation throughout the food chain from production storage.
