Development of Nanoemulsions with Tucumã (Astrocaryum vulgare) Fruits Oil

Abstract

Astrocaryum vulgare is a palm species which belongs to the family Arecaeae, being commonly known as tucumã and widely distributed through Amazon. Tucumã fruit is a typically Amazonian raw material, which can be used for extraction of oil with great economic importance. However, to our knowledge, tucumã remain unexplored concerning development of a nanobiotechnology product. The aim of the present study was to develop nanoemulsions containing tucumã fruits oil. Formulations prepared with different blends of sorbitan monooleate and polysorbate 80 at HLB 11.0, 12.0, 12.25, 12.5, 12.75, 13.0, 13.25, 13.5, 13.75 and 14 were considered nanoemulsions. Smallest mean droplet (156.6±0.6557 nm) was observed for nanoemulsion at HLB 13, which was considered required HLB value of this oil. On this context, this study provides valuable information concerning nanobiotechnology of Amazonian oils with great interest for pharmaceutical, cosmetics and food industries.
