Microencapsulation of curcumin using a fatty acid-based eutectic mixture.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Curcumin (CUR), a naturally occurring polyphenol derived from turmeric, has attracted significant interest due to its wide range of therapeutic properties. However, its clinical and industrial applications are hindered by inherent challenges such as poor solubility, low stability, and limited bioavailability. To address these limitations, encapsulation techniques have been explored as a promising strategy to enhance curcumin's stability, solubility, and bioavailability. In this study, for the first time, curcumin, as a herbal bioactive compound, was successfully microencapsulated within a bio-based phase change material (PCM). A eutectic mixture of stearic acid and lauric acid in a 1:3 molar ratio was utilized as the PCM for the microencapsulation process. The resulting microcapsules were thoroughly characterized using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). The findings revealed that curcumin was effectively encapsulated within the PCM, exhibiting a well-defined morphology. Furthermore, the release profile of curcumin from the microcapsules was evaluated in phosphate-buffered saline (PBS, pH 7.4) at two different temperatures (37 and 45
