Problems solved by technology

[0002] Nowadays, in order to prolong the shelf life of stewed beef and mutton, people often add preservatives to stewed beef and mutton products. Adding preservatives will affect the physical and mental health of consumers, especially adding preservatives in excess. In addition, through observation And experiments have found that adding more salt to stewed beef and mutton products has a better antiseptic effect than less salt, but adding too much salt will also affect the taste and quality
