Beef is the second largest meat food in China, second only to pork. Beef has a high protein content, but a low fat content. It is delicious, so it is loved by people and enjoys the reputation of "the favorite among meat". Dried beef contains a variety of minerals and amino acids needed by human body, which not only maintains the chewy flavor of beef, but also does not deteriorate for a long time. The production of beef jerky should first choose the first-class raw materials, followed by the production process and production time. When drying, we must also consider the time of sunshine, and the procedures must be closely controlled.
