In Sohag City, 400 samples were collected from different food markets of different meat products from two companies with high and low prices (e.g., minced meat, kofta sausage, beef burger, and luncheon meat) for determining food fraud. Light, fluorescence, and scanning electron microscopy (SEM) were used to examine the samples. "Special histochemical stains" permit the microscopic examination of different cell types, structures, and/or microorganisms. Histological examination revealed variant tissue types, besides skeletal muscles. Nuchal ligaments, bones, hyaline cartilages, white fibrocartilages, large and medium arteries, cardiac muscles, tendons, and collagenous connective tissues comprised the capsule of a parenchymatous organ. Additionally, a crystal of food additives was recognized using light microscopy and SEM. SEM allows the visualization of bacterial contamination. Using different microscopic anatomy techniques is an efficient methodology for qualitative evaluations of various meat products. No difference in quality was observed between low- and high-priced meat products.
在索哈杰市，从两家价格高低不同的公司的不同肉类产品（如碎肉、烤饼香肠、牛肉汉堡和午餐肉）的不同食品市场收集了400个样本，以确定食品欺诈情况。使用光学显微镜、荧光显微镜和扫描电子显微镜（SEM）对样本进行检查。“特殊组织化学染色”可对不同细胞类型、结构和/或微生物进行显微镜检查。组织学检查发现，除骨骼肌外，还有不同的组织类型。颈韧带、骨骼、透明软骨、白色纤维软骨、大中动脉、心肌、肌腱和胶原结缔组织构成了一个实质性器官的被膜。此外，通过光学显微镜和扫描电子显微镜识别出了食品添加剂晶体。扫描电子显微镜可以观察到细菌污染情况。使用不同的显微解剖技术是对各种肉类产品进行定性评估的有效方法。未观察到低价和高价肉类产品在质量上有差异。
