Seed and peel of umbu fruit have nutrients and compounds with bioactive potential

By Virgínia Martins da Matta, Embrapa Agroindústria de Alimentos, Rio de Janeiro, RJ, Brazil

The umbu fruit contains nutrients and compounds with bioactive potential not only in their edible part, but also in their peel and seed. Researchers from Embrapa in partnership with the Federal University of Rio de Janeiro (UFRJ) of Brazil discovered these results after analyzing the nutritional composition of the fruit. The article, titled “Nutrients and bioactive compounds of pulp, peel and seed from umbu fruit”, authored by Leilson Ribeiro, Eliseth Viana, Ronoel Godoy, Sidinea Freitas, Suely Freitas and Virgínia Matta, is published in the journal Ciência Rural (vol. 49, no. 4).

The researchers evaluated the nutritional composition and bioactive compounds of samples of seed, pulp, peel and commercial pulp of the fruit, determining the centesimal and mineral composition, total phenolic compounds and antioxidant capacity. The data show the high antioxidant capacity of the seed and the pulp and a high content of phenolic compounds, found in the peel of the fruit. In addition, the umbu seed had higher fiber and mineral contents such as iron.

For the researcher Virgínia Martins da Matta, the knowledge of the composition of by-products can add value to the umbu and strengthen the productive chains of the fruit, related to family farmers. “Coproducts can be used as raw material to obtain different products and ingredients. From the peel, for example, we can get extracts rich in phenolic compounds or carotenoids, and the seed, a flour rich in minerals”, exemplifies the researcher.

This is the first study that presents the complete composition of the three fractions of the umbu fruit, according to Leilson de Oliveira Ribeiro, author of the paper. As well as other researches on Brazilian fruits carried out by Godoy, et al. (2013), Inada, et al. (2015) and Omena, et al. (2012), the concern of this study is also to add value to agroindustrial co-products to reduce residues and increase the sustainability of their production processes
