Dragon fruit-based energy balls are emerging as an attractive functional snack because they combine natural sweetness, appealing color, dietary fiber, antioxidants, and convenience in a ready-to-eat nutraceutical format. Dragon fruit (Hylocereus Undatus) contains betalains, phenolic compounds, flavonoids, vitamin C, minerals, and seed-associated lipids that support its use as a functional food ingredient with antioxidant, anti-inflammatory, and broader health-promoting properties [cite:32][cite:35][cite:40]. When incorporated into energy balls, dragon fruit can contribute both nutritional value and visual appeal, while complementary ingredients such as oats, nuts, seeds, dates, or protein-rich binders can improve texture, satiety, and macro-nutrient balance [cite:46][cite:44][cite:49].

This review summarizes the formulation rationale, ingredient classification, phytochemical profile, functional and nutraceutical properties, mechanisms underlying health effects, evaluation parameters, shelf-life considerations, safety issues, regulatory aspects, development challenges, and prospects of dragon fruit-based energy balls. Particular emphasis is placed on nutritional composition, oxidative stability, pigment retention, water activity, packaging, and sensory optimization because these factors determine whether the product can be positioned successfully as a healthy shelf-stable snack [cite: 43] [cite: 50] [cite: 33].
