Abstract

The economic value of dragon fruit peels can be increased through the process of diversification, hence, it becomes a food waste when not used often. This research provides a broader view of the terms of the strategy to achieve dragon fruit diversification and food independence towards the realization of food security. This research aims to determine the effect of dragon fruit peel substitutes on the antioxidant vitamin c, water content, and milk pie fiber to improve human health. Furthermore, the vitamin C content, fiber, and water content were analyzed, and the data obtained were processed using ANOVA followed by DMRT at p≤0.05. 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. While the total fiber content of the sample ranged from 8.01-10.13%, sample S3 has the highest fiber content of 10.13%. The more dragon fruit peels are added, the higher the fiber content of dragon fruit peels milk pie. The use of dragon fruit peels which were originally a food waste can improve the quality of milk pie products in terms of water content, fiber, and vitamin C. The addition of dragon fruit peels can also reduce the water content in the milk pie and make the product more durable.

“…The processing of food waste generally aims to provide positive impact on the global community. One type of fruit that has food waste potential is dragon fruit; the outer part or skin of dragon fruit, which is quite large and heavy, is simply discarded without further processing [11].…”

“…Recycling is not only used for processing the food wastes, but also for adding nutritional value to a food. Several studies have found out how to transform dragon fruit peels into dessert pies, nata, and cookies [11,25,26]. The type of utilization of dragon fruit peels waste for savory food has also been studied, especially dragon fruit peels processed into meatballs, chicken nuggets, and tempe [27,28,29].…”
