Resumo
The fresh almond is the main form of consumption of the Brazil nut, however, co-products
such as water-soluble extract can be exploited commercially. Aqueous extracts are beverages
from plant origin, which have nutritional commercial appeal in the health aspects, as no
animal fats and high mineral contents. Thus, we aimed to determine water-soluble extract
formulations, by technological processes in pilot scale, of the Brazil nut, to realize proximate,
microbiological, sensory and rheological characterization, of the drinks obtained, and evaluate
the physical and chemical stability, physical and microbiological of the extracts in the
presence and absence of light. The Brazil nuts extracts had total solids, protein, fat and
minerals, high, and can be considered products with high nutritional value. The Brazil nut
extracts showed a pseudoplastic fluid non-Newtonian behavior. The extracts developed with
preservatives had useful life of at least twenty-one days. Was unable to establish a
relationship between the stability of the Brazil nut extract and the light incidence. The
research of the water-soluble extract of Brazil nut can contribute with information to the use
of this product in human meal.
