In this study, we compared that sensory characteristics and nutritional components of ice cream supplements with various levels(1, 2, 3％) raw and frozen citron juice. Vitamin C was not detected in frozen citron juice 1％ added group. The content of vitamin C was 4.7 mg/100g in raw citron juice 3％ added group. But it detected 1.0 mg/100g in 3％ frozen citron juice added group. Free sugars were detected sucrose, lactose and maltose. Those amounts of all samples were lower than control group and were lower goes to citron juice added ratio higher. Organic acids in ice creams were detected oxalic acid, malonic acid, malic acid and citric acid. The citric acid content was higher than other organic acid. Especially, citric acid content was the highest in raw citron juice 3％ added group (6.3 mg/100g). But it′s content was low in all frozen citron juice added groups (0.5-0.6 mg/100g).
