The present invention discloses a photodynamic inactivation method of Salmonella. The method using riboflavin as a photosensitizer adopts a blue light source to photodynamically inactivating Salmonella, which belongs to the technical field of sterilization for inactivating food-borne pathogenic Salmonella. The photosensitizer used in the present invention is one of essential vitamins of the human body. The riboflavin (a food-grade photosensitizer) is safe and non-toxic, and has a significant effect for inactivation of Salmonella. Moreover, the present invention is capable of controlling the risk of salmonellosis, short in treatment time, simple in operation, and capable of thoroughly inactivating Salmonella, and has certain control and prevention effects. The present invention provides a method for effective inactivation of Salmonella in food, which is low in cost, simple in operation and wide in application and can better promote the development of the food sterilization technology.

This disclosure relates to techniques to sanitize eggs. More specifically to sanitizing eggs in a manner such that damage to the cuticle of the egg during sanitization is reduced or eliminated. A method includes the activation of photoactivated sanitizing agent with an appropriate wavelength of light at an intensity that eliminates, reduces, or slows the production of, pathogens on the shell of an egg. The photoactivated sanitizing agent can include an exogenously-applied photoactivated sanitizing agent and an optional photosensitizer, which can be activated with light having a wavelength known to activate the exogenously-applied photoactivated sanitizing agent. The photoactivated sanitizing agent can include an endogenously-derived photoactivatable compound. Light in the Soret band can be utilized to activate the endogenously-derived photoactivated sanitizing agent.
