Abstract
Soy-oil, which seems to come from the soybean-oil in the course of producing soysauce, has not been used for food up to now.
Soy-oil presents considerably other natures different from soybean-oil by being given physical, chemical and microbiological reaction, during the manufacturing process of soy-sauce.
This oil shows the high acid value and rancidity, so it is not used for food. We have made clear of some special features of soy-oil in this study.
