Photosensitizer compositions, devices, and methods of use for surface sanitization of processed food products

A method for disinfecting a food surface, the method comprising:

• a) providing a food having in contact with a surface thereof, or within an effective range, a composition comprising Riboflavin;
• and
• b) irradiating the food with a violet-cyan light having a wavelength between about 380 nm and about 500 nm, with broad-spectrum white light having a wavelength between about 400 nm and about 700 nm, or with a combination thereof, to a fluence of at least 5 J/cm2.

A method for disinfecting a food surface, the method comprising:

• a) providing a food having in contact with a surface thereof, or within an effective range, a composition comprising Erythrosin B;
• and
• b) irradiating the food with a blue-green light having a wavelength between about 420 nm and about 565 nm, with broad-spectrum white light having a wavelength between about 400 nm and about 700 nm, or with a combination thereof, to a fluence of at least 5 J/cm2.

A method for disinfecting a food surface, the method comprising:

• a) providing a food having in contact with a surface thereof, or within an effective range, a composition comprising Sunset Yellow FCF;
• and
• b) irradiating the food with a violet-green light having a wavelength between about 380 nm and about 565 nm, to a fluence of at least 5 J/cm2.
