1 · What the graph read from it

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.

2 · The registry

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

This study aims to investigate how endogenous walnut pellicle polyphenols (WPP) alter the structural and functional properties of walnut protein isolate (WalPI). WPP influence was assessed by adjusting polyphenol content in walnut meal (WM) through treatments that peeled and dephenolized the pellicle. Results showed that WPP decreased the β-sheet content of unpeeled walnut protein isolate (UWalPI), increased random coil structures, and induced structural unfolding. These structural changes raised the water-holding capacity of UWalPI from 1.72 to 2.48 g/g and enhanced foaming capacity and foam stability by 31.12% and 46.44%, respectively. Conversely, surface hydrophobicity declined by 62.9%, oil-holding capacity reduced to 2.44 g/g, and emulsifying capacity, solubility, and thermal stability were compromised. Scanning electron microscopy indicated WPP-induced rearrangement and aggregation, molecular docking simulations predicted interactions between WPP and WalPI. The results clarify the mechanisms of WPP-WalPI interactions and provide strategies for the application of WM and WalPI in food processing.
