  • How is corn germ oil extracted?
  • As a kind of high-quality vegetable oil, corn germ oil has been studied for many years by using lots of extraction methods including pressing extraction, Soxhlet extraction, organic solvent extraction, supercritical CO 2 and aqueous enzymatic [124, 125, , , ].
  • Why is corn germ oil so popular?
  • Corn germ oil is well received by consumers because of its preferable appearance, mild aroma, high levels of polyunsaturated fatty acids and high oxidative stability . Corn germ oil is also applied as an ingredient in the formulation of snacks, baking mixes and bakery products.
  • What is corn germ used for?
  • Corn germ was usually firstly extracted oil and the defat germ (corn germ meal) was also considered a good ingredient for all livestock species . It has good palatability, rich in digestible amino acids and hemicellulose, and can be used as protein feed for monogastric animals, as well as protein and energy feed for ruminants .
  • What percentage of corn kernel oil is stored in corn germ?
  • Typically, the crude oil of corn kernel (4%) is almost stored in corn germ and the entire germ mainly contains oil (48%), protein (13%), and starch (12%). However, the recovery germ composition in oil (18%–41%), protein (12%–21%) and starch (6%–21%) is also influenced by growing conditions, genetic factors, and isolation methods .
  • Is corn germ oil edible?
  • Furthermore, some functional compounds can also be found in corn germ oil such as Vitamin E, phytosterols (Table 5). Corn germ oil was confirmed to be one of the edible oils by WHO (World Health Organization) and FAO (Food and Agriculture Organization of the United Nations) due to its superior oxidative stability and nutritive properties. Table 4.
  • Can corn germ meal be used as a substitute for corn grain?
  • Corn germ meals have been widely used as a substitute for corn grain in Brazil, China and Ethiopia. However, the corn germ meal was detrimental to the performance of lamb . Furthermore, it is not recommended to extrapolate the results of those trials to all types of corn germ meal.
