• What is the extraction of secondary metabolites in oilseeds?
  • The extraction of plants¡¯ secondary metabolites is of a great interest. This extra process can take place either for the extraction and elimination of anti-nutriments, or for the valorisation of added-value molecules. Table 13 presents some of the solvents and processes used for the extraction of various secondary metabolites found in oilseeds.
  • Which country produces the most rapeseed oil?
  • The largest producer of soybean oil is China (29%), followed by the USA (19%) and Brazil (16%). Canada (17%), China (15%) and Germany (13%) are the main producers of rapeseed. Sunflower oil production is dominated by Ukraine and the Russian Federation, accounting for over 50% of the world¡¯s production.
  • What are the main products and by-products of a bio-refinery?
  • Overall, main products and by-products are the output of a so-called bio-refinery. The extraction of oil from lipid-bearing materials, such as oilseeds, generates large volumes of by-product rich in proteins, fibres and minerals, known as oilseed cake or meal . There exists certain ambiguity in the use of the terms ¡°cake¡± and ¡°meal¡±.
  • Can 2-MeTHF be used as an alternative for soybean oil extraction?
  • Recently, Claux et al. investigated the use of 2-MeTHF as an alternative for the extraction of soybean oil from ground soybean seeds.
  • What type of oil is rapeseed?
  • Rapeseed Brassica napus, commonly known as rapeseed or canola, is one of the world¡¯s most abundant oil crops. It is a prehistoric crop thought to be first cultivated around 2000 BCE . The traditional varieties of these oilseeds produce an oil rich in erucic acid (up to 60%, known as HEAR (high erucic acid rapeseed) oil) .
  • Which oilseed has the highest lipid content?
  • Sunflower seed and rapeseed have the highest crude lipid content, ranging between 44.5% and 54.4% for sunflower, followed by rapeseed with a content of 28.5 to 54.9%, as per Table 4. Flaxseed¡¯s lipid content varies between 30¨C47%, while soybean contains the least amount of lipid among the four oilseeds with only 15 to 25%.
