According to the result obtained, the total vitamin C content in the sample varies between 1.12 and 1.20 mg/100g. Sample S3 had the highest vitamin C content, and the more the dragon fruit peels are added, the higher the vitamin C content of dragon fruit peels milk pie. The total water content of the sample ranged from 22.08% - 23.74%. Sample S1 which is a pie without the addition of dragon fruit skin has the highest water content of 23.74%. While sample S2 which is a pie with the highest addition of dragon fruit skin has the lowest water content of 22.08%. The more dragon fruit peels are added, the lower the water content in the dragon fruit peels milk pie. This makes the milk pie product to be crispier when dragon fruit peels are added.
