• What is deodorization in edible oil refining?
  • In current edible oil refining, deodorization is also the process in which free (nonesterifed) fatty acids (in the case of physical refining) and volatile contaminants are stripped and unwanted color pigments are degraded (heat bleaching).
  • What is a softcolumn deodorization column?
  • a SoftColumn deodorization column means there is no risk of clogging or polymerization. The resultant flow pattern and the high turbulence this creates, along with optimized oil distribution and the completely airtight design, mean the installation is self-cleaning and free of odour.
  • Who invented deodorizer?
  • In the USA, it was Eckstein who developed the first industrial deodorizer. In 1891, he demonstrated that the flavour of alkali-refined cottonseed oil could be greatly improved by blowing live steam through the oil at high temperature (160-175¡ãC).
  • What is the current trend in edible oil deodorization?
  • In their ¡®historical sketch¡¯ of edible oil deodorization, Lee and King stated in 1937 that the ¡®current trend (in edible oil deodorization) is toward continuous processes with automatic control¡¯ .
  • What is edible oil deodorization?
  • Industrial deodorizers Edible oil deodorization is performed industrially in different ways (continuous, semicontinuous or batchwise) with various configurations of deodorizers (horizontal or vertical vessels, tray-type or packed columns).
  • Why is palm oil deodorized at 260¡ãC?
  • The latter effect is called ¡®heat bleaching¡¯ and it is most pronounced during deodorization/steam refining of palm oil, where the thermal breakdown of carotenes is targeted. Heat degradation of carotene is very slow at 210¡ãC, but takes only a few minutes at T > 260¡ãC. This is one reason why palm oil is typically deodorized at 260¡ãC.
