Heating turmeric in oil between 50°C and 70°C for 4 to 6 hours pulls out useful plant chemicals.
Scientific Claim
Hot maceration using temperatures of 50–70°C and durations of 4–6 hours can extract measurable amounts of total phenols, carotenoids, and β-carotene from turmeric rhizomes into vegetable oils.
Original Statement
“This study aimed to determine the total phenol, carotenoid, and β-carotene content in turmeric rhizome extract in Extra Virgin Olive Oil (EVOO) and Virgin Coconut Oil (VCO). The method used for extracting was hot maceration, with variations in heating times of 4, 5, and 6 hours and variations in temperature of 50, 60, and 70 °C.”

Assessment Explanation
Based on abstract only - full methodology not available to verify. The claim is purely descriptive of extraction feasibility under lab conditions. No causal or health claims are implied, so verb strength is appropriately conservative.
More Accurate Statement
“Hot maceration at temperatures of 50–70°C for 4–6 hours is associated with the extraction of measurable amounts of total phenols, carotenoids, and β-carotene from turmeric rhizomes into vegetable oils.”
