Deodorization is basically a vacuum steam stripping at elevated temperature during which free fatty acids and volatile odoriferous components are removed to obtain bland and odorless oil. Although the process is commonly named “deodorization”, it is a combination of three different operations: distillation (stripping of volatile components), actual deodorization (removal of odoriferous components), and heat bleaching (thermal destruction of pigments) (De Greyt & Kellens, 2000; Gibon et al., 2007; Kellens & De Greyt, 2000). Optimal deodorization parameters (temperature, vacuum, and amount of stripping gas) are determined by the type of oil and the selected refining process (chemical or physical refining) but also by the deodorizer design.
