## Abstract
Coffee and pumpkin seeds are both well-known sources of antioxidants, but few studies have explored their combined effects. This study investigates the potential of a coffee-pumpkin seed blend to enhance nutritional intake and offer health benefits. Three coffee formulations with varying coffee-to-pumpkin seed ratios (80:20, 70:30, and 60:40) were prepared and analyzed for their nutritional and antioxidant properties. Proximate analysis, following AOAC methods, was used to determine macronutrient content, while vitamin levels were quantified using High-Performance Liquid Chromatography (HPLC). Mineral content was assessed by Atomic Absorption Spectrometry (AAS), and antioxidant capacity was evaluated using the DPPH radical scavenging assay. Shelf life was estimated using Accelerated Shelf-Life Testing (ASLT). Results showed that Formula C (60:40 ratio) had the highest protein, fat, zinc, andiron content, while Formula A (80:20) was richest in carbohydrates, fiber, and vitamin A (β-carotene). Antioxidant activity increased with pumpkin seed content, with Formula C exhibiting the highest capacity. Sensory evaluation favored Formula A, and shelf-life testing revealed it had the longest shelf life. This study highlights the potential of pumpkin seed-infused coffee as a functional beverage, with enhanced antioxidant capacity and improved nutritional profile. However, further research, including in vivo studies and clinical trials, is needed to confirm the health benefits and identify the optimal formulation for maximum efficacy. Key words: Antioxidant; functional drink; nutritional properties; pumpkin seed coffee.
