Characterization of Microcapsule Containing Walnut (
Article in International journal of preventive medicine, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundWalnut green husk (WGH) extract has been known as potential preventive and therapeutic antioxidants and antimicrobials due to its high polyphenol content. In this study, preparation of spray dried WGH extract-loaded microcapsules by maltodextrin and its blending with two other natural biodegradable polymers, pectin, or alginate were investigated.
methodsIn this study, encapsulation efficiency (EE), total phenol content (Folin-Ciocalteu reagent method), antioxidant (DPPH scavenging assay) and antimicrobial activities (agar well diffusion method) structural (SEM and FTIR studies), and release properties of WGH extract-loaded microcapsules were investigated.
resultsHigh retention of phenolic content in microcapsules indicated the successful encapsulation of WGH extract. Addition of biopolymers to maltodextrin matrix has a positive effect on EE and other properties of microcapsules. The microcapsules prepared with mixture of maltodextrin and pectin had higher EE (79.35 ± 0.87%) and total phenolic (TP) content (56.83 ± 1.04 mg gallic acid equivalents [GAE]/100 g) in comparison to maltodextrin and alginate mixture (EE: 75.21 ± 0.24%, TP content: 54.33 ± 1.53 mg GAE/100 g) and maltodextrin only matrix (EE: 72.50 ± 1.00%, TP content: 50.67 ± 1.35 mg GAE/100 g). Extract-loaded microcapsules also showed nearly spherical structure, good antioxidant (with the percentage DPPH inhibition ranged from 75.17 ± 1.42% to 80.87 ± 2.29%), and antimicrobial properties (with mean inhibition diameter zone ranged from 7.76 ± 0.86 mm to 11.53 ± 0.45 mm). Fourier transform infrared analyses suggested the presence of extract on microcapsules. The
conclusionsWGH extract microcapsules can be used as novel and economic bioactive phytochemical and therapeutic agents to prevent oxidation and microbial activity.
