The combination of fruit pulps from different species, in addition to multiplying the offer of flavors, aromas and textures, favors the nutritional spectrum and the diversity of bioactive principles. The objective was to evaluate and compare the physicochemical characteristics, bioactive compounds, profile of phenolic compounds and in vitro antioxidant activity of pulps of three species of tropical red fruits (acerola, guava and pitanga) and of the blend produced from the combination. The pulps showed significant values of bioactive compounds, with emphasis on acerola, which had the highest levels in all parameters, except for lycopene, with the highest content in pitanga pulp. Nineteen phenolic compounds were identified, being phenolic acids, flavanols, anthocyanin and stilbene; of these, eighteen were quantified in acerola, nine in guava, twelve in pitanga and fourteen in the blend. The blend combined positive characteristics conferred by the individual pulps, with low pH favorable for conservation, high levels of total soluble solids and sugars, greater diversity of phenolic compounds and antioxidant activity close to that of acerola pulp. Pearson's correlation between antioxidant activity and ascorbic acid content, total phenolic compounds, flavonoids, anthocyanins and carotenoids for the samples were positive, indicating their use as a source of bioactive compounds.
不同种水果果肉的组合，除了增加风味、香气和质地的多样性外，还有利于营养谱和生物活性成分的多样性。本研究旨在评估和比较三种热带红色水果（樱桃、番石榴和草莓番石榴）的果肉及其组合混合果肉的理化特性、生物活性化合物、酚类化合物组成和体外抗氧化活性。果肉具有显著的生物活性化合物含量，其中以樱桃含量最高，除番茄红素外，其他参数均高于其他两种水果。共鉴定出 19 种酚类化合物，包括酚酸、黄烷醇、花青素和芪类化合物；其中，18 种在樱桃中定量，9 种在番石榴中，12 种在草莓番石榴中，14 种在混合果肉中。混合果肉结合了各果肉的积极特性，具有低 pH 值有利于保存、高总可溶性固体和糖含量、更多种类的酚类化合物和接近樱桃果肉的抗氧化活性。样品的抗氧化活性与抗坏血酸含量、总酚类化合物、类黄酮、花青素和类胡萝卜素之间存在正相关，表明它们可作为生物活性化合物的来源。
