Applicant's summary and conclusion
- Conclusions:
- Under the conditions of the study, the NOAEL of soybean oil in rat was found to be equivalent to 19% in diet.
- Executive summary:
The effect of dietary soybean oil was investigated (as control) in a subchronic toxicity study.
Diet containing 7.5% fully hydrogenated soybean oil (plus 11.5% soybean oil as normal fat source) was fed to 20 Sprague-Dawley rats/sex for 91 d. the control group was fed with 19% soybean oil for same duration.
There was no indication of any systemic toxicity (including body weight gain, food consumption, organ weights, urinalysis, clinical chemistry, haematology, gross and histopathology) in the soybean oil group.
Hence, under the conditions of this study, the NOAEL of soybean oil in rat was found to be 19% in diet.
