PROBLEM TO BE SOLVED: To provide a production method of a high quality dried persimmon without generation of mold, oxidation browning and dullness in which sulfur fumigation and hot water processing are eliminated.SOLUTION: A production method of a dried persimmon comprises peeling step S1-1 of peeling a raw material persimmon, and drying step S1-3 of making an infra-red ray irradiate a peeled persimmon in an infrared-ray chamber, and performing drying, ageing and astringency removal thereof to obtain the dried persimmon. In the production method of the dried persimmon, the drying step S1-3 is a drying method in which infrared-ray irradiation is started within one hour after peeling by eliminating sulfur fumigation and hot water processing to the peeled persimmon, coating is made on the surface of the peeled persimmon within 48-72 hours, and thereby the mold and oxidation are prevented from occurring.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】硫黄燻蒸や熱湯処理をせずに,カビや,酸化褐変,くすみが生じない良質な干し柿の製造方法の提供。【解決手段】干し柿の製造方法であって,原料柿を剥皮する剥皮工程S1-1と,赤外線室において剥皮柿に対して赤外線を照射して乾燥,熟成,及び脱渋し,干し柿を得る乾燥工程S1-3とを含む。乾燥工程S1-3が,剥皮柿に対して硫黄燻蒸及び熱湯処理を行わずに,剥皮後1時間以内に赤外線照射を開始して,48~72時間以内に剥皮柿の表面に皮膜を張らせ,カビと酸化を発生させないようにする乾燥方法である干し柿の製造方法。【選択図】図1
