Abstract: The present invention relates to a method for manufacturing citron syrup to ordinarily eat the citron syrup as food. According to the present invention, the method comprises: a step of mixing juice prepared by juicing only flesh, except for peels, which is prepared by selecting and washing only good ripe citrons with clean water and cutting the same into pieces (2 to 4 equal parts), and sugar in a weight ratio of 1:1.1 to dissolve the sugar at 5 to 16°C for 24 hours, wherein the mixture is stirred every six hours so that the sugar is completely dissolved and mixed; a step of putting the mixture in an aging container and aging the mixture at a low temperature of -10°C for 7 to 10 days; a step of transferring the mixture to a stirrer, stirring the mixture for at least one hour, and packing the mixture; and a step of aging the packed mixture in a frozen state of -15 to -20°C. Accordingly, since the citron syrup has a lower freezing point by being pickled in sugar, low temperature aging and low temperature storage are enabled, thereby preventing fiber from being destroyed, preventing odor and black mold due to room temperature aging, and maximally preserving the unique flavor, taste, color, and nutrients of citron. In the previous patent ′METHOD FOR MANUFACTURING CONCENTRATED CITRON EXTRACT′, a citron extract was aged at 10 to 16°C for 20 to 25 days at a low temperature, but it is a wrong manufacturing process generating odor. In this ′METHOD FOR MANUFACTURING CITRON SYRUP′, citron syrup is aged at sub-zero temperature, and thus odor and black mold are not generated.
