Study of two sugarcane by-products as source of secondary metabolites and heat-induced compounds with potential bioactive applications.
Article in Scientific reports, 2025. 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
A crucial step in the engineering of bioactive materials from sugarcane by-products is understanding their physical, chemical, and biological characteristics, particularly their molecular composition and biological activities. This study aimed to characterize the physicochemical properties of methanolic and aqueous extracts from sugarcane molasses and vinasses, determine their antioxidant capacity, and identify key compounds of biological interest; specifically phenolic compounds (PCs) and heat-induced compounds (HICs). Through non-targeted analytical approaches, we identified a diverse range of PCs and HICs in the extracts. In vitro tests revealed significant antioxidant effects in both aqueous and methanolic fractions, with the methanolic extracts showing superior free radical scavenging capacity. This bioactivity was linked to PCs such as p-coumaric acid, 4-hydroxybenzoic acid, 4-hydroxybenzaldehyde, chlorogenic acid, and schaftoside, as well as HICs like 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one (DDMP); 4-hydroxy-2,5-dimethyl-3(2H)-furanone (HDMF); 2,6-dimethoxyphenol; and 1,6-anhydro-β-D-glucopyranose. These findings underscore the potential of sugarcane molasses and vinasses as sources of bioactive compounds, which can be engineered into new materials with promising biological properties for health, pharmacological, and food industry applications. Furthermore, our research highlights the integration of bioengineering, material science, and sustainable practices within the sugarcane industry by promoting the valorization of by-products, contributing to resource efficiency and industrial innovation under circular economy principles.
