Ultrasound-induced modification of pea pod protein concentrate.
Article in Current research in food science, 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
Agricultural by-products have emerged as valuable resources for the sustainable production of high-quality food ingredients. Ultrasound, a novel and environmentally friendly technology, is an effective physical method for solvent-free protein modifications. This study explores the conversion of pea pods as an agricultural by-product into value-added protein-based food ingredients with multifunctional properties enhanced by high-intensity ultrasound (US). Pea pod protein concentrate in the native form (PPPC-N) obtained by alkaline extraction/isoelectric precipitation was subjected to ultrasound-induced protein modification using response surface methodology at varying amplitude (40-80 %), time (2-20 min), and protein concentration (1-5 % w/v). The US process parameters were separately optimized based on maximum solubility, emulsification, and antioxidant activity. Protein concentrates were characterized at optimal conditions (80 % amplitude, 11 min, and 1 % protein; the desirability of 0.964) based on the maximum emulsification. The optimized PPPC by US (PPPC-US) exhibited a superior solubility performance compared to PPPC-N in the pH range of 2.0-9.0. The optimal US treatment enhanced the emulsifying attributes and foaming capacity of PPPC-N with an increase of 49 %. Moreover, oil binding capacity significantly increased while water binding capacity and foam stability decreased. Developing functional ingredients from pea pod proteins can open new possibilities in formulating innovative products.
