| الوصف: | Açaí is a tropical fruit, typical of the Amazon and has been drawing attention due to its antioxidant capacity and high content of anthocyanins, responsible for several pharmacological and medicinal properties, as well as potential use as a natural dye. Due to the high perishability, the development of new products from the açaí power, which present greater stability to the storage time are being produced. The evaluation period was 25 days at a temperature of 25°C. The following parameters were evaluated: ascorbic acid, chlorophyll, total anthocyanins, total flavonoids, total polyphenols and antioxidant activity by ABTS●+ and DPPH● methods. Microbiological analysis were performed for Coliforms at 35°C and 45°C, Mesophiles, Staphylococcus coagulase positive, Molds, Yeasts, and Salmonella sp. The contents of ascorbic acid, total polyphenols and flavonoids differed statistically (p ˂ 0.05) from each other, throughout the storage. However, the antioxidant activity by the DPPH● method remained stable and the microbiological analysis remained within the current legislative standards. It is concluded that the açaí powder maintained its properties throughout the storage, being an excellent source of bioactive and phenolic compounds. ; El açaí es una fruta tropical, típica de la Amazonía y ha llamado la atención por su capacidad antioxidante y alto contenido de antocianinas, responsable de varias propiedades farmacológicas y medicinales, además de su uso potencial como colorante natural. Debido a la alta perecebilidad, se está desarrollando el desarrollo de nuevos productos a partir de açaí, que ofrece mayor estabilidad y tiempo de almacenamiento, como un polvo. El objetivo de esta investigación fue evaluar la estabilidad del polvo de açaí durante un período de 270 días a una temperatura de 25 ° C. Los siguientes parámetros se evaluaron cada 30 días: ácido ascórbico, clorofila, antocianinas totales, flavonoides totales, polifenoles totales y actividad antioxidante mediante los métodos ABTS●+ y DPPH●. Se realizaron ... |
