Sustainable development has driven the advancement of the bioeconomy by promoting responsible use of natural resources. In this context, the Brazilian Cerrado, a biome rich in biodiversity, stands out as a source of innovative ingredients, such as baru (Dipteryx alata Vogel). This study aimed to develop and evaluate a protein energy drink, including characterization of its physicochemical and microbiological properties, as well as conduct a market survey. The product was formulated using a water-soluble extract of baru combined with functional ingredients—caffeine and taurine—in accordance with the current Brazilian legislation. Physicochemical analyses demonstrated appropriate levels of protein (15.24 ± 1.3 g/100 g) and soluble solids (3.0 ± 0.1 °Brix) and a suitable pH (6.30 ± 0.1), in compliance with national standards. Microbiological assessments (of the presence of Salmonella spp., Bacillus cereus, Enterobacteriaceae, molds and yeasts, mesophilic bacteria, coliforms, and Escherichia coli) confirmed the product's safety for consumption, meeting food quality and safety regulations. The market research revealed significant consumer acceptance, particularly among individuals with busy lifestyles and an interest in natural alternatives. The packaging design highlights sustainability and regional identity, reinforcing the connection with the local biodiversity. Overall, the beverage demonstrates strong competitive potential in the functional beverage market, driven by growing consumer interest in affordable, natural, and protein-enriched energy products. Its development integrated innovation, environmental responsibility, and the valorization of native resources from the Brazilian Cerrado.
