A study carried out in Vale do Juruá, in Acre, identified that traditional varieties of beans grown by family farmers have high levels of proteins and natural antioxidants, with potential for market appreciation. The research is part of the thesis of professor Guiomar Almeida Sousa, from the Federal Institute of Acre (Ifac), supervised by Amauri Siviero, from Embrapa Acre.

According to the survey, the Costela de Vaca and Manteiguinha Branco varieties reached up to 27% protein, a higher rate than the national and world average. The beans also had high levels of anthocyanins, natural antioxidants, ranging from 420 to 962 micrograms per gram, a value above that recorded in white and colored varieties.
The study also showed that the grains maintain their conservation for up to 12 months, reinforcing the storage potential and quality of traditional seeds. According to the researchers, crops in the Juruá Valley are developed in traditional agricultural systems, adapted to the local climate and biodiversity. The region concentrates the greatest diversity of beans in the state, with 23 varieties registered in the municipality of Marechal Thaumaturgo.
The authors highlight that knowledge about the nutritional composition and genetic conservation of varieties can contribute to adding value to the product, generating income for small producers and encouraging the creation of Geographical Indication and organic production seals.
The results on Acre’s traditional agricultural systems will be presented during the Agrizone event, at COP30, in Belém (PA), as an example of the Amazon’s cultural and genetic heritage.
