Abstract:

The ethyl esterification of soybean oil deodorization distillate (SODD) was optimized using an orthogonal array design. Esterification rate was investigated with respect to time, temperature, sulphuric acid concentration and weight ratio of ethanol to SODD. The optimum conditions for these factors were 60 min, 80 ℃, 2% and 1:1, respectively. Under these conditions, the esterification rate was 90.86%.

Key words: deodorization, distillate, esterification
