  • What is a comprehensive approach on corn oil?
  • TL;DR: In this article, a comprehensive approach on corn oil, considering aspects on chemical composition, physical properties, conventional and alternative extraction methods, refining processes, quality analysis, modification processes, as well as nutritional properties and industrial application of this relevant vegetable oil.
  • What are the steps in chemical refining of corn oil?
  • In chemical refining, the crude or degummed corn oil is subjected to the steps of neutralization, clarification, winterization, and deodorization, for the removal of FFA, pigments, waxes, and odoriferous compounds, respectively.
  • How is corn oil refined?
  • The resulting crude oil is further refined with the consecutive steps of degumming, neutralization, bleaching, winterization, and deodorization and refined oils directly used or alternatively processed through hydrogenation, fractionation, and interesterification. Corn oil is slightly yellowish, with a mild and characteristic odor and taste.
  • What is the process of industrialization of corn oil?
  • The process of industrialization of corn oil, in general, is divided into two main stages: the extraction of crude oil which also yields a corn oil cake coproduct and the subsequent refining of the crude oil.
  • Does corn oil need a degumming operation?
  • According to Moreau (2005), the degumming operation of corn oil is mandatory only when the oil will be further refined via physical refining process. Refining can be defined as a set of serial steps for transforming crude oils into edible oils. Basically, there are two types of refining operations, chemical and physical.
  • What is refined corn oil used for?
  • Refined corn oil is used for frying, salad oils, and as raw material in various lipid modification processes to obtain technical fats. In this way, it shows prominence among vegetable oils, due to its excellent sensorial and nutritional characteristics and good performance in diverse food applications (O'Brien, 2008).
