Development and nutritional evaluation of a chocolate-based functional yoga nutrition bar

Abstract

The present study was undertaken to develop and evaluate a chocolate-based functional yoga nutrition bar formulated with nutrient-dense ingredients including oats, nuts, seeds, dates, honey, and natural peanut butter.Three formulations (T1, T2, T3) were prepared and assessed for sensory quality, proximate composition, vitamin and mineral content, antioxidant potential, and microbial safety.Sensory analysis using a 9-point hedonic scale revealed high acceptability across all samples, with T2 scoring highest in overall preference.Proximate analysis demonstrated a well-balanced nutritional profile, offering 437.8 Kcal energy, 12 g protein, 23 g fat, 45.7 g carbohydrates, and 5 g dietary fiber per 100 g.The bar also provided essential micronutrients such as 3 mg vitamin E, 0.6 mg vitamin C, 2.3 mg iron, and 70 mg calcium.Microbial analysis confirmed the product's safety and shelf stability, showing compliance with food safety norms.The findings support the potential of a chocolate-based yoga nutrition bar as a functional, clean-label snack option for wellness-focused individuals.
