Antioxidant addition to dough or frying oil: effects on the oxidative stability of deep-fat fried noodles.
Article in Food science and biotechnology, 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
This study evaluated the oxidative stability of deep-fat fried noodles and frying oils when antioxidants were added either to the dough or to the frying oil. Hydrophilic and hydrophobic antioxidants, including α-tocopherol, ascorbyl palmitate, trolox, and ascorbic acid, were tested over 100 continuous frying cycles. Trolox showed the highest antioxidant activity when added to frying oil, while ascorbyl palmitate was more effective when added to dough. Ascorbic acid consistently exhibited low antioxidant performance regardless of application site and showed prooxidant effects, particularly when applied to frying oil. During storage at 60 °C, fried noodles containing ascorbyl palmitate in dough and trolox in oil showed the highest oxidative stability, while those containing ascorbic acid were more susceptible to lipid oxidation. These results suggest that antioxidant efficacy is influenced by both compound polarity and application site, as well as by their thermal stability, migration behavior, and interactions with the food matrix.
