Preservatives are food additives used to maintain the original quality and nutritional value of food. They can prevent food spoilage by inhibiting the growth and reproduction of microorganisms, thus prolonging the shelf life. China has approved more than 30 kinds of edible preservatives, and there are strict regulations on their use. It can be considered that preservatives are non-toxic and have no side effects on human body within the scope of safe use.

The total time of canned yellow peach from raw materials to finished products is less than 6 hours, and after high temperature treatment, the bacteria in the container can be killed, and after sealed packaging, it can be stored for a long time at room temperature.
