Abstract

Butterfly pea and red dragon fruit had high antioxidant activity and magnesium content. Both play an important role in lowering blood pressure. The purpose of this research was to analyze the effect of butterfly pea brew addition on antioxidant activity and magnesium content of red dragon fruit jelly, determine the selected formula and its nutritional content. This research is an experimental study with a one-factor Completely Randomized Design (CRD) method, two repetitions, and three treatment levels of butterfly pea addition, namely F1 (5 grams), F2 (7 grams), and F3 (9 grams). Antioxidant activity was analyzed using DPPH method while magnesium content using Atomic Absorption Spectrophotometry (AAS). Data analysis was carried out using ANOVA test then continued with Duncan’s test if the p-value < 0.05. The selected formula was determined using the De Garmo method. The results showed that the addition of butterfly pea brew had a significant effect on increasing antioxidant activity (p = 0.047) and magnesium content (p = 0.000) of red dragon fruit jelly. The selected formula (F3) per serving size (100 grams) contains 41.52 kcal energy, 0.55 grams protein, 0 grams fat, 9.83 grams carbohydrate, 85.32 mg magnesium, and 25974.56 ppm antioxidant activity. The recommended serving size for lowering blood pressure is three serving sizes per day.
