Problems solved by technology

[0007] In order to solve the problems in the prior art that it is more difficult to preserve the quality and freshness of fancy steamed buns, and the time for quality and freshness preservation is shorter, the present invention provides a method for prolonging the quality and freshness of steamed buns. Under the circumstances, set the radiation absorption dose, use cobalt-60 gamma rays and electron beams to irradiate the product outside the body, and the incident gamma particles or electrons penetrate into the product to cause physical, chemical and biological reactions to kill the product. All or part of the harmful microorganisms are kept sterile or low-bacterial in a closed environment, so that the product is kept in a sterile or low-bacterial environment, so that the product is sterile or low-bacteria without reproduction, and the long-term quality assurance and maintenance of the product are completed. The purpose of keeping fresh
