Abstract
Albino rats were fed on the diets containing about 7.2% of soybean oil and with or without 1% of each synthetical surfactant. By the way the dried powder of the molasses butanol distiller's soluble (MS) was also tested as a surfactant.
The effects on the digestibilities of the protein, fat and organic matter of the diets were not remarkable.
The O/W type surfactants, such as polyoxyethylene sorbitan monostearate, POES monolaurate and polyoxy ethylene stearate, and hot water soluble W/O type surfactant such as propylene glycol stearate have promoted the growth of rats. But MS and water-insoluble W/O type surfactant such as sorbitan monostearate did not promoted. The growth promoting effect of POES monolaurate was not improved by the addition of MS.
Little effect was seen on the weight distribution of visceral organs of the rats.
