Evaluation of autolysis induced histologic alterations in skeletal muscle tissue of non-traditional meat animals

Abstract

Raw meat is characterized by various natural cellular processes that lead to its chemical content alteration. The purpose of the present study is to evaluate autolysis induced histologic alterations in skeletal muscle tissue of cow elk. On this study the authors used skeletal muscle tissue of 2-year-old cow elk. The tissue was sampled from m. quadriceps femoris. The study results showed that in 48 hours post mortem linear striation in muscle tissues was expressed. But 72 hours post mortem the integrity of muscle fibers degraded and they became inconsistently stained. The obtained data showed that post mortem alterations were characterized by significant degradation and separation of muscle fibers and nuclei and nuclear structures lysis.

Social, ethical, environmental, economic and technological aspects of rabbit meat production - A critical review

“…By 10 h of autolysis, the pH indicator stabilizes at the level of 5.4–5.6. Other researchers [ 107 , 108 ] described a comparable duration of autolysis and the onset of maturation of RM – 9–12 h, which is surprisingly faster than the maturation time of poultry, beef, pork and lamb meats ( Fig. 6 ).…”

“…6 ). Kaimbayeva et al [ 108 ] revealed the deep nature of autolytic processes in the longest back muscle 10 h after rabbit slaughter, as a result of which physico-chemical, biochemical and sensory properties of meat are formed, ensuring high quality products. Less intensive processes took place in the piriformis muscle, as well as the pre-scapular muscle, which was explained by the peculiarities of the structure of these parts of the muscular system.…”

Enhancing Milk Productivity in Dairy Cows Through the Optimized Utilization of Oilseed Byproducts

“…Soybeans account for more than half of world production and more than a quarter of the protein used for food and animal feed [18][19][20]. Feed for efficient and rational feeding of farm animals should contain a sufficient amount of nutrients: macronutrients, minerals, and vitamins [21][22][23]. Contaminated samples must be processed for detoxification.…”
