dc.description.abstract | The enzymatic glycerolysis conditions in the production emulsifier by using the rendering waste oil were optimized in the present study. The effects of changes in duration (1-27 h), temperature (50-80 degrees C), enzyme (5-20%), and glycerol (5-20%) concentration, addition of solvent (acetone, acetonitrile, chloroform, methanol, ethanol, and tert-butanol) and water addition (3.5% of glycerol rate), and ultrasound application on the enzymatic glycerolysis reaction medium for mono- and diglyceride production were investigated. After determining the optimum conditions, the effects of the ultrasonic bath on the physic-chemical and rheological properties of emulsifier, the oxidation tests were examined. Using the preparative column chromatography method, three different emulsifier compositions were achieved and named E100, E50-50, and E50-40-10 by their monoglyceride, diglyceride, and triglyceride contents, respectively. Then, the post-purification emulsion properties and rheological behaviors of emulsifier samples were determined. E50-40-10 emulsifier was found to be the best sample in terms of rheological properties and emulsion stability. | tr |
