The invention discloses a low-temperature green raisin washing and sterilizing method. Green raisins are washed and sterilized through precooling saline solutions after being precooled, and then are dried through cold air. The method has the advantages that according to the characteristics that the green raisins are high in fructose content, high in reconstitution performance, prone to browning (changing color) when encountering high temperature, high humidity and strong ultraviolet rays, and prone to deformation, the invention provides the green raisin dry and cold method washing and non-thermal sterilization processing method, the liquid saline water, namely edible salt is adopted for low-temperature sterilization, after the green raisins are washed through the method, attachments on the green raisins are washed off to the maximum extent, rehydration of the green raisins can be reduced, the green raisins are kept from browning, the hygiene and microbiological indicators can reach the national food safety and hygiene standards, and the original color and lustre, flavor and shape keep unchanged.
