The production of soybean products would result in wastewater mixed with soybean yellow serofluid.
DHA (150 mg) and lecithin (900 mg) were dissolved in 30-ml alcohol and then mixed with soybean oil (5,000 mg) and glyceryl monostearate (150 mg).
After a 24-h period for radioactive decay, two 100-μL aliquots were taken from each sample and mixed with soybean casein digest medium and fluid thioglycollate medium, respectively, and incubated for 14 days at 37 °C.
An interaction (P < 0.10) was observed between CT and SBM on ruminal digestibility and digestion rate of crude protein (CP): when mixed with soybean meal, CT decreased the ruminal digestibility and, consequently, reduced the digestion rate of CP.
Others edible oil-based products did not contain any of the target PAHs, except few products of garlic oil mixed with soybean or sunflower oil (ΣPAH4 levels up to 4.1 μg/kg), sea buckthorn oil (ΣPAH4 level 20.9 μg/kg) and two multicomponent products containing oil from apricot kernel.
After all running-in test of all lubricating conditions, 5 wt.% of boric acid powder mixed with soybean oil had contributed a hybrid tribofilm and resulted in the lowest friction coefficient value in the range of 0.06 0.07.
