Mineral profile of cocoa powder: Analytical approach in commercial samples.
Article in Journal of the science of food and agriculture, 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
backgroundCocoa powder is widely used in the food industry and has high nutritional value due to its composition, including minerals. The main factors related to the presence of minerals in cocoa powder are soil, processing, and cultivation practices. Given the high consumption of cocoa products and the need for information on their mineral composition, accurate assessments are important to ensure quality and consumer safety. In this study, the mineral content of commercial alkalized and natural cocoa powder samples from 12 countries was determined.
resultsTotal mineral content was as follows: K, 16 921-63 731 mg kg⁻¹; P, 2129-9253 mg kg⁻¹; Mg, 2900-6183 mg kg⁻¹; Ca, 488-3985 mg kg⁻¹; Fe, 97.3-1154 mg kg⁻¹; Al, 5.65-917 mg kg⁻¹; Mn, 34.6-59.1 mg kg⁻¹; Cu, 21.9-48.1 mg kg⁻¹; Ni, 5.64-14.9 mg kg⁻¹; Cr, 0.479-18.5 mg kg⁻¹; and Cd, 0-1.30 mg kg⁻¹. Mineral content varied among samples, and hierarchical cluster analysis (HCA) grouped them into four clusters, as confirmed by principal component analysis (PCA). Sixteen samples exceeded the maximum cadmium limits.
conclusionThe proposed procedure was effective for determining minerals in cocoa powder. The samples showed wide variation across all elements and provided insights into the macro- and micronutrient composition of alkalized and natural cocoa powders. © 2026 The Author(s).
