National grapes stand out in reviews and have health benefits

A joint survey by the Federal Institute of Sertão Pernambucano (IF Sertão PE), the Federal University of Bahia (UFBA) and Embrapa highlighted the richness of compounds present in Brazilian whole grape juice, from varieties created by the latter. The study identified substances known as bioaccessible phenolics, phytochemicals or nutraceuticals. Its main characteristic is the high absorption capacity by the body during the successive stages of digestion, simulated in the laboratory to provide a clearer and more precise vision of how its interaction with the organism occurs.

Among the many benefits observed are strengthening the immune system, preventing obesity and diabetes, as well as combating heart and neurodegenerative diseases. The juice extracted from the grape known as BRS Carmen stood out for its bioaccessible phenolic content, serving as an indicator for varieties from this matrix to be further explored in future studies. Each of these, however, is understood as unique and complex by researchers.

The Vale do Submédio São Francisco region is currently a producer hub for whole grape juice, especially from varieties adapted to the semi-arid tropical climate. The estimated annual volume is 35 million liters, including concentrated juices. This illustrates the success of the expansion of cultivation, previously more restricted to the South of the country. With the arrival in the Southeast, Center – West and Northeast, new frontiers were explored and it was necessary to deal with higher temperatures and solar radiation.

In this sense, Embrapa's actions were decisive, since the new varieties introduced were successful in theoretically adverse biomes. The entity's Grape and Wine program, created in 1985, gave more competitiveness to producers who were able to operate in larger areas, with different climates, but improving quality. In addition to genetic changes, there were also guidelines regarding management, combating pests and diseases and sustainability. The advances, after decades of joint effort, became palpable throughout the production chain, boosting consumption considerably.

In addition to BRS Carmen, BRS Magna, BRS Violeta and BRS Cora were evaluated in the study.
