• What is vegetable oil?
  • Abstract Vegetable oil (VO) is a naturally occurring hydrocarbon in innumerable compositions and abundantly found in natural plants, seeds and fruits.
  • Where did vegetable oil come from?
  • Vegetable oil discovery and devel-opment was originated as an alternative source. Afterward, the oilseeds pressing and the extraction especially from olives became the primary source of cooking oil. Other resources such as radishes, sesame seeds, or flax seeds have also been used for oil production.
  • What are the compositions of vegetable oils?
  • Table 1. Content of compositions of typical FAs of different vegetable oils. The main FAs were palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid, which were 10.2%-15.2%, 2.6%-7.5%, 13.3%-36.1%, 40.4%-63.9% and 3.9%-12.8%, respectively.
  • How much vegetable oil is produced a year?
  • 2.2. The major vegetable oil crops The principal traded vegetable oil crops generate about 210 Mt (million tonnes) of edible oil, and OECD-FAO estimates suggest production will increase to about 250 Mt by 2030 (OECD-FAO, 2021); it is likely that a further ca. 50 Mt of oil is consumed locally without entering major supply chains.
  • What crops produce vegetable oil?
  • Cotton-seed, soybean, canola, palm, peanut, sunflower are examples of crops producing vegetable oil . The use of vegetable oil in the food industry is higher than that of industrial usage (5¨C7%) . Vegetable oil has also been used as biofuel oil in diesel engines .
  • How to increase oil production from vegetative tissue biomass?
  • Recently, numerous tech-niques (i.e., genetic transformation, catalytic transformation) have been developed to enhance the oil productions from (i) higher vegetative tissue biomass as compared to fruits or seeds and (ii) carbohydrates modification into oil .
