Historical Insights Into the Purification of Polyphenol Oxidase From Plants.
Review in Food science & nutrition, 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
Over the past 50 years, different methods have been developed to purify polyphenol oxidase (PPO), a key enzyme involved in the oxidation of phenolic compounds in plants. This review presents a comprehensive summary of the advances in purification techniques, highlighting the evolution of the methods used over the years to achieve partially purified or pure enzymes, while also discussing their advantages and limitations. Furthermore, this review examines the biochemical properties of PPO that are most significant for its potential biotechnological applications. A comparison of the amino acid sequences and tertiary structures of crystallized PPO is also included, enabling the identification of structural similarities among PPO from different species. Finally, this review has been written as a guide for decision-making regarding the selection of an appropriate PPO purification strategy, taking into account the required level of purification and the enzyme's source.
