Biological Safety and Functional Properties of Açaí Seed Extract: Antioxidant Capacity and Prebiotic Potential.
Article in Journal of food science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Açaí (Euterpe oleracea) is widely recognized as a functional food due to its nutritional value and abundance of bioactive compounds. Its seeds, representing approximately 80%-95% of the fruit mass, constitute an abundant agro-industrial byproduct with promising biotechnological potential. This study aimed to chemically characterize a 70% ethanolic extract obtained from E. oleracea seeds through liquid chromatography-mass spectrometry (LC-MS) annotation and total phenolic content (TPC) determination, as well as to investigate its antioxidant activity, prebiotic potential, cytotoxicity, and mutagenic safety profile. The extract was obtained by percolation using 70% ethanol. Antioxidant activity was evaluated by the DPPH assay, while prebiotic potential was assessed through submerged in vitro fermentation with Lactiplantibacillus plantarum LP90, monitoring bacterial growth and medium acidification. Cytotoxicity was evaluated in Caco-2 cells using a resazurin assay, and mutagenicity was investigated using the micronucleus and Ames tests. LC-MS annotation revealed a phenolic-rich profile, mainly composed of procyanidins. The extract showed a TPC of 123.12 ± 5.70 mg GAE/g dry weight and significant antioxidant activity (EC
