Overview

Quality analyses reveal how well different oils perform for human nutrition, suggesting potential culinary applications.

Key Points

This research investigates the lipidic composition and thermal stability of oils from four different plant sources, assessing their suitability for nutrition.
Analyzed quality, identity, and stability of vegetable oils from Dipteryx alata, Acrocomia totai, Mauritia flexuosa, and Caryocar brasiliense.
Measured acidity values, peroxide index, refractive index, and relative density of each oil.
Examined fatty acid profiles and nutritional quality indices.
Conducted UV-vis and fluorescence analysis to identify compounds present in oils.
Performed thermal analyses to assess stability at high temperatures.
Acidity values were acceptable for tonka bean and pequi fruit oils, but exceeded Codex Alimentarius limits for macaw palm oil.
All samples maintained a suitable peroxide index.
Similar refractive indices and relative densities were found across all oils.
Fatty acid profiles revealed that macaw palm, buriti palm, and pequi fruit oils are mostly monounsaturated, while A. totai oil is predominantly saturated.
Buriti palm oil showed the highest quality similar to olive oil and exhibited the greatest thermal stability.
