The study aimed to develop and evaluate sunflower butter as a minimally allergenic alternative to traditional plant-based butters and as a potential fat substitute in pâté bread. Sunflower butter, prepared from sunflower seeds, was analyzed for its chemical composition, antioxidant activity, oxidative stability, microbiological safety, and sensory characteristics. The     results highlighted its rich nutritional profile, including high protein (22.5g/100g), dietary  fiber (9.6g/100g), and vitamin E content (22.1IU/100g). It also demonstrated significant antioxidant activity, with a phenolic content of 735mg/100g and high oxidative stability during storage at 4°C. Microbiological analysis confirmed its safety, showing no growth of  E. coli, molds, or yeasts over three months. When incorporated into pâté bread as a fat substitute, sunflower butter improved sensory attributes, including taste, texture, and overall acceptability. These findings suggest sunflower butter as a nutritious, health-beneficial, and allergen-friendly alternative, with potential applications in food industries.
