Tomato Pomace as a Valuable Resource: Characterization of Sunflower and Rapeseed Oil Extracts from Ox Heart Tomato (

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
This study investigates the potential use of tomato pomace, a by-product of tomato pulp and seeds, as a functional additive in sunflower and rapeseed oils. The aim was twofold: to improve the oxidative stability of the oils and to enhance their nutritional value for potential food applications. Extractions were performed using different concentrations of tomato pomace (2%, 4%, and 6%) at varying temperatures (40°, 50°, and 60 °C) and stirring speeds (150, 200, and 250 rpm). The resulting samples were evaluated for antioxidant activity, peroxide value, and color characteristics. To further assess oil composition and stability, advanced analytical techniques were employed. Fourier-transform infrared spectroscopy (FTIR) identified key functional groups and structural modifications, while differential scanning calorimetry (DSC) revealed differences in thermal stability across the samples. High-performance liquid chromatography (HPLC), optimized for compound separation and detection, identified several carotenoids, including canthaxanthin, lutein, lycopene, and alpha carotene. Notable differences between extracts made with sunflower versus rapeseed oil were observed, reflecting variations in chemical composition, extraction efficiency, and oil-pomace interactions. In conclusion, the incorporation of tomato pomace into vegetable oils not only enhances oxidative and thermal stability but also enriches the oils with valuable bioactive compounds, supporting their potential use in functional food formulations.
