Understanding the effects of pre-treatment and extraction methods on lipid fingerprint of cashew nut shell liquid (CNSL) by non-targeted lipidomics analysis.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Cashew nut shell liquid (CNSL) is a brown liquid obtained from cashew nut waste, with several applications as a renewable feedstock for polymeric industries. To obtain it, cashew nuts must undergo thermal pre-treatment processes to soften cashew nut shell (CNS) and extraction operations to separate CNSL from CNS. Although it is well known that CNSL is mainly composed of phenolic lipids, the chemical identity of minor components has not been widely explored. Thus, this study analyzed the lipid profile of CNSL using untargeted lipidomics aimed to understand the effects of CNSL extraction and cashew nut pre-treatment methods. Here, based on multivariate analysis we elucidated the differences between CNSL extracted by Soxhlet or mechanical pressing from CNS pre-treated by roasting or steaming. It was found that CNS pre-treatment displays a significant effect on CNSL regardless of the method used most likely related to lipid thermal degradation in raw nut samples. Similarly, it was found that extraction methods cause variances on lipid profile due to solvent selectivity in soxhlet method. Thus, the study expands the knowledge related to chemical differences in terms of lipid profile associated with CNSL processing, demonstrating that performing pre-treatment on CNS affects CNSL indistinctively of the method implemented.
