Bactrian camel () meat, as a product of national geographical indication, is mainly produced in the northwest regions of China. This study systematically evaluated the edible quality, nutritional quality, and carcinogenic substances of Bactrian camel meat using different heating times in four thermal processing methods (steaming, boiling, frying, and microwaving). Compared with the control group (uncooked), the thermal processing of meat demonstrated lower redness and moisture content; higher shear force values and protein, fat, and ash contents; and sharply increased the levels of amino acids and fatty acids. The moisture content of the fried and microwave-treated meat was significantly lower than that of the steamed and boiled meat ( < 0.05). Steamed meat was higher in protein but had a lower fat content than the other three processing methods ( < 0.05). Compared with frying and microwaving, meat from steaming and boiling showed higher levels of essential amino acids and lower shear force values. However, the smoke generated during frying led to the formation of large amounts of polycyclic aromatic hydrocarbons (PAHs) and nitrites, and the levels of these substances increased with heating time. In addition, with the extension of the heating time, the shear force of the meat also increased gradually ( < 0.05). In summary, steaming and boiling were proven to be suitable processing methods for preserving better nutritional values while delivering less carcinogenic risk. With our results, we have established a nutritional database for Bactrian camel meat, providing a reference for selecting a suitable thermal processing method.
双峰驼肉作为国家地理标志产品,主要产于中国西北地区。本研究采用蒸、煮、煎、微波四种热加工方式,在不同加热时间下,系统评估了双峰驼肉的食用品质、营养品质和致癌物质。与对照组(未烹饪)相比,肉的热加工显示出较低的红度和水分含量;较高的剪切力值以及蛋白质、脂肪和灰分含量;并显著提高了氨基酸和脂肪酸的水平。煎制和微波处理的肉的水分含量显著低于蒸煮的肉(<0.05)。蒸制的肉蛋白质含量较高,但脂肪含量低于其他三种加工方式(<0.05)。与煎制和微波处理相比,蒸煮的肉必需氨基酸水平较高,剪切力值较低。然而,煎制过程中产生的烟雾导致大量多环芳烃(PAHs)和亚硝酸盐的形成,且这些物质的含量随加热时间增加。此外,随着加热时间的延长,肉的剪切力也逐渐增加(<0.05)。综上所述,蒸煮被证明是保留较好营养价值同时致癌风险较低的合适加工方式。基于我们的研究结果,我们建立了双峰驼肉的营养数据库,为选择合适的热加工方式提供参考。
