Nutritional composition, sensory acceptability and shelf-life evaluation of wheat-corn chaff composite cake.
Article in Frontiers in nutrition, 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
Background: In many low- and middle-income countries (LMICs), like Ghana, cereal-based baked products such as cakes are widely consumed due to their affordability and convenience. However, conventional wheat-based cakes are often characterized by low micronutrient density, limiting their contribution to adequate nutrition. Objective: This study aimed to develop wheat-corn chaff composite cakes and evaluate their nutritional composition, sensory acceptability, and shelf-life stability. Methods: Composite cakes were produced by substituting wheat flour with 0, 10, 15, and 20% corn chaff. Proximate composition was determined using standard AOAC methods, while mineral content (iron, zinc, and magnesium) was analyzed using Atomic Absorption Spectrophotometry. Sensory evaluation was conducted among 75 panelists using a hedonic scale and Relative Importance Index. Shelf-life stability was predicted using moisture-based accelerated models. Results: Incorporation of corn chaff significantly increased ash content, indicating improved mineral density, while maintaining desirable carbohydrate and protein levels. Fiber content also improved significantly from 0.58 ± 0.07 to 2.15 ± 0.12. The composite cakes provided appreciable amounts of essential minerals (Iron = 2.87 ± 0.06 mg/100 g, Zinc = 2.70 ± 0.14 mg/100 g, Magnesium = 95.0 ± 1.41 mg/100 g), demonstrating improved micronutrient composition compared to conventional wheat cake. Sensory evaluation showed significant differences among formulations ( Conclusion: Incorporation of 10% corn chaff significantly improves the micronutrient quality of wheat-based cakes while maintaining consumer acceptability and appreciable shelf-life stability. This approach offers a practical strategy for enhancing the nutritional value of commonly consumed baked products and promoting sustainable utilization of maize by-products.
