Optimization of β-Carotene Extraction from Tucuma Fruit (<i>Astrocaryum aculeatum</i>) Using Ionic Liquids: Evaluation of Efficiency, Thermal and Light Stability.

ABSTRACT: This study aimed to optimize the extraction of β-carotene from the pulp of tucumã (Astrocaryum aculeatum), an Amazonian fruit rich in bioactive compounds, using the ionic liquid [C₄mim]-[BF₄] as a sustainable alternative to conventional acetone extraction. Using a central composite design, the optimal extraction conditions were determined: a solid-to-liquid ratio of 1:5, 10 min of extraction time, and 65.5 W of power. The [C₄mim]-[BF₄] method achieved a higher yield (12.10 mg/100 g) than acetone (8.75 mg/100 g), with greater thermal and photolytic stability. In an oily medium at 90 °C, the extract exhibited a half-life of 3466 min, and colorimetric analysis indicated reduced color degradation, confirming its potential as a stable natural c
