Effects of Infrared Treatment on Some Constituents and Functional Properties of Chia Seed.
Article in Food science & nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Infrared treatment has become increasingly popular in the food industry due to its advantages over conventional heating. The aim of this study is to enhance health beneficial components and functional properties of chia seeds by using infrared treatment at different powers (700, 900, 1100 W) and times (25 and 50 min). Infrared treatment caused a significant, gradual increase in the total phenolic content and antioxidant capacity of the chia samples. Total flavonoid and total dietary fiber content increased at 700 and 900 W treatments. Chlorogenic acid, ferulic acid (except 1100 W-50 min treatment), rutin, and quercetin (only at 700 W-50 min & 900 W-25 min treatments) increased, whereas caffeic and p-coumaric acid decreased by infrared treatment. FTIR spectra for infrared treated samples have all specific peaks reported in the literature for chia. Slight changes were observed in peak intensities of infrared treated samples. Infrared treatment enhanced emulsion activity (up to 900 W-25 min) and stability (up to 700 W-50 min) but adversely affected the water and oil holding capacities. Infrared treatment of chia seeds enhanced the extractability of health beneficial constituents (e.g., phenolics and flavonoids) probably due to thermal breakdown of cellular components, and this may result in a health promoting effect. Utilization of infrared treated chia seeds as a raw material in value-added food products is promising.
