Yak meat has a very high nutritional value, is rich in protein, amino acids and trace elements of carotene, calcium, phosphorus and the like, is extremely low in fat content, is extremely high in caloricity, and has significant effects of improving disease resistance, cell viability and organ functions of a human body. The yak meat in the existing market appears in the form of dried yak meat and frozen fresh yak meat. Because the shelf life of fresh meat is short and the transportation of fresh meat is difficult, the so-called fresh meat in the existing market appears in the form of frozen yak meat. With the improvement of the living conditions of people, the requirements of people for foods are also gradually increased. Due to the defects in the processing mode, the existing frozen yak meat still has problems of being heavy in mutton flavor, rough in meat quality and too tough for people to chew. The invention provides a processing method of chilled yak meat. The processing method of chilled yak meat comprises the steps of slaughtering, acid discharge, cutting, packaging and transporting.
