The invention discloses a producing method of dried muskmelon. The method includes: selecting fresh muskmelon, cleaning, sterilizing, peeling, taking flesh, cutting into slices, hardening, performing color protecting, blanching, performing solute osmosis, drying and reshaping. Beneficial effects of the producing method are that: the producing method overcomes the color browning problem of the muskmelon, preserves the original color and flavor of the muskmelon, enhances the deep processing capability of agricultural and sideline products, adopts rejected muskmelon as the raw material for deep processing of the muskmelon so as to achieve full utilization of raw materials, reduces waste of the muskmelon resource, completes muskmelon industrial production through producing downstream muskmelon products, increases the kinds of the agricultural and sideline products subjected to deep processing in Xinjiang, and enriches the market; and the producing method utilizes the resources reasonably and protects the environment.
