Incorporating Watermelon Rind into Jackfruit Seed Drink: A Functional Drink Rich in Antioxidant and Phenolic Compounds

Functional foods are believed to be medicinal due to their nutritional content, phenolic and various phytochemical compounds. Jackfruit seeds and watermelon rind are often discarded as food waste. This study aimed to determine the antioxidant activity, vitamin C, and total phenolic content in jackfruit seed drink JSD with watermelon rind as a functional drink. Antioxidant activity was observed based on DPPH inhibition. The results showed significant differences between formulas based on vitamin C, total phenolic content, and antioxidant activity with JSD 2 as the best formula. JSD 2 showed total phenolic vitamin C, and antioxidant activity tasks of 37.83 ± 0.68 mg/100g; 29.86±0.60 mgGAE/g; 40.98±0.78%. The addition of watermelon rind into JSD significantly increases health potential.
