Safety assessment of heated diacylglycerol oil: Subchronic toxicity study in rats
چکیده انگلیسی

Diacylglycerol oil is an edible oil with similar taste and usability characteristics as conventional edible oil rich in triacylglycerol oil. The objective of the present study was to evaluate potential adverse effects of heated diacylglycerol and triacylglycerol oil in rats following subchronic administration. The heated diacylglycerol and triacylglycerol oils were prepared separately following deep frying potato slices at 180 °C for 8 h per day for three days. Sprague Dawley rats were fed diets containing different ratios (concentrations) of heated to unheated diacylglycerol oil. The ratio of heated to unheated diacylglycerol was as follows: 0%/5.5% (control-1; Group 1), 1.0%/4.5% (Group 2), 2.75%/2.75% (Group 3), and 5.5%/0% (Group 4). Two additional groups received the feed containing 5.5% of unheated or 5.5% of heated triacylglycerol oil. Compared to the unheated oils, feeding of heated diacylglycerol or triacylglycerol oil did not reveal any toxicologically significant changes in clinical observation, body weights, body weight gains, feed consumption, ophthalmic examinations, functional observational battery and motor activity, clinical pathology evaluations and organ weights. Similarly, terminal necropsy did not reveal treatment-related gross or histopathology findings. Based on the results of this subchronic study, the no-observed-effect levels (NOELs) of heated diacylglycerol or triacylglycerol oil were 5.5%, the highest levels tested. The mean dietary exposure levels at the highest dose for the heated diacylglycerol and triacylglycerol oil for male and female rats ranged from 3178 to 4120 mg/kg/day.
