Fruit growing is one of the most important sectors in Brazil, which is considered to produce the most consumed tropical fruit in the world, as well as having a variety of exotic fruits with potential for the development of new products. Among these fruits is the cajá, considered a rich source of phytochemicals such as anthocyanins, carotenoids, flavonoids and ascorbic acid. Mangaba is also a tropical fruit with high nutritional value and an exotic and peculiar flavour. The aim of this study was to survey the existing literature on these two fruits, with an emphasis on their production, storage and their use in the development of new products. These are foods with a short shelf life due to their high perishability, thus requiring processes that increase the shelf life of these fruits. Technological innovations that include mangaba have been patented, showing that the use of this fruit is growing and in the literature several studies have been found using cajá as a raw material for the development of new products.
