Physical refining of coconut oil: Effect of crude oil quality and deodorization conditions on neutral oil loss

摘要: In the present study, neutral oil loss (distillative and mechanical carry-over) during physical refining of coconut was quantified. Neutral seems to depend on both crude quality process conditions deodorization. The distillation volatile glyceridic components (monoand diglycerides), originally in oil, confirmed as major cause for loss. amount these oils cannot be derived such from initial free fatty acid content. A lower deodorization pressure with less sparge steam resulted a larger than higher more steam. “deodorizability” test laboratory scale under standardized (temperature=230°C, pressure=3 mbar, time=60 min, steam=1%), evaluate obtain accurate prediction expected content distillate, is described.
