The TBA test is a colorimetric technique in which the absorbance of a red chromogen formed between thiobarbituric acid and malondialdehyde is measured.
According to G. Hocman (7), the acceptable daily intake of BHA [and BHT] is at present considered to be 0.6 milligrams per kilogram of body weight. He says, "In spite of their possible tumor-promoting properties they could not be considered overtly toxic. Their pronounced chemoprotective role against some forms of chemical carcinogenesis deserves considerable attention."
Hocman's acceptable daily intake equates to 27 milligrams per 100 pounds of body weight. Crystaline BHT is soluble in animal fat and alcohol (but poorly in water). It is also caustic to body tissues. With these facts in mind, oral injestion of BHT should be done in conjunction with eating a meal containing a fair amount of animal fat. (BHT with a dose of medicinal alcohol might work as well, but perhaps not on an empty stomach).
