  • Which industrial technologies are used for vegetable oils’ refining?
  • The present review aimed at comparing the two main industrial technologies used for vegetable oils¡¯ refining, namely, chemical refining and physical refining. Chemical refining removes free fatty acids by soda neutralization.
  • What percentage of soybean oil is recovered by water degumming?
  • The amount recovered by water degumming varies depending upon the oil quality but will usually be 2.5 to 3.0% of the crude soybean oil degummed. Lecithin processing and utilization are covered in detail in Chapter 10. Soapstock, or refining byproduct lipids, consists of soap, neutral oil, phosphatides, and some unsaponifiables.
  • What are the by-products of refining soybean oil?
  • Refining of soybean oil, to make a neutral, bland-flavored, and light-colored oil, results in several by-products. The by-products consist of various mixtures of phosphatides, unsaponifiables, glycerides, free fatty acids, and soap. Lecithin contains mostly hydratable phosphatides, together with some free fatty acids and neutral oil (glycerides).
  • What is a Physical refining process?
  • In general, physical refining includes the following three main processing steps: Sometimes the dewaxing process is added for types of oils rich in waxes (e.g., fatty acids with low solubility in oils and high-melting esters of fatty alcohols), such as corn, rice bran, canola, and sunflower oils [ 29 ].
