  • 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).
  • Is degumming necessary for refining soybean oil?
  • Degumming is not essential for the refining process, and it is common practice for many processors to refine crude soybean oil without degumming (2). Soapstock from refining nondegummed oil is much greater in quantity than that from degummed oil and has a higher content of phosphatides, which would have been removed in degumming.
  • What is the main objective of soybean processing?
  • Production of high quality meal and crude oil is the main objective in soybean processing, and thorough knowledge of the technical system and disciplined operation are required. The use of animal fats as raw material for shortening production has been avoided because of low supply, and religious restrictions of certain beliefs.
  • Why is refined soybean oil important?
  • For those reasons, refined soybean oil is widely used all over the world. Production of high quality meal and crude oil is the main objective in soybean processing. For achievement, thorough knowledge of the technical system and disciplined operation are required. The starting point is reception of soybeans at the processing plant.
  • What are Crude soybean byproduct lipids?
  • Crude soybean byproduct lipids consist of soaps of soybean fatty acids, triglycerides, phosphatides, and degradation products as well as small amounts of sterols, tocopherols, pigments, proteins, and carbohydrates. To reduce weight and stabilize the product for storing and handling, raw soapstock is commonly acidulated with sulfuric acid.
  • 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.
