Improving stability of frying oils and food quality with addition of dried olive mill wastewater.

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
The olive oil industry in Mediterranean countries generates large quantities of waste, recognized as a cheap source of valuable compounds. This study evaluated the antioxidant properties, nutritional value and antimicrobial activity of dried olive mill wastewater (OMWW) and its effect on vegetable oils (corn and soybean) during frying and selected food products. OMWW was found to contain 5.75 g GAE/L of free phenols, with oleuropein being the most bioactive compounds. Refined vegetable oils enriched with OMWW (600 mg/L) showed an increase in induction times, indicating higher oxidative stability compared to oils with BHT. Sensory evaluation revealed no significant differences (p < 0.05) in characteristics of French fries which fried in enriched refined oils versus controls. OMWW polyphenols effectively retarded lipid oxidation and improved oxidative stability of oils, nutritional value of French fries, and sensory attribute of mayonnaise. Beneficial use of OMWW as a natural antioxidant was recommended by the present study.
