    Abstract: A freshness keeping method is provided. The freshness keeping method irradiates, with irradiation light, crops after harvesting. The irradiation light includes a first peak wavelength within a wavelength range from 400 nm to 480 nm inclusive, a second peak wavelength within a wavelength range from 500 nm to 650 nm inclusive, and a third peak wavelength within a wavelength range from 700 nm to 750 nm inclusive. An intensity of the irradiation light at the third peak wavelength is 5% or more of an intensity of the irradiation light at the first peak wavelength.
