• What is groundnut oil manufacturing process?
  • Groundnut oil manufacturing process is divided into two methods, the first is mechanical pressing and the second is solvent extraction. Mechanical pressing can extract 85% oil and the remaining oil is extracted by the solvent extraction method.
  • How to make peanut oil from groundnuts?
  • According to mechanical pressing technology, you can divide the peanut oil production process into three phases. These are peanuts preparation, pressing and crude oil refining. Step 1: Cleaning Step 2: Dehulling Step 3: Cooking Step 4: Pressing Step 5: Filtration After harvesting groundnut are received at processing facilities.
  • How much groundnut is produced in India?
  • The groundnut area in India during 1988¨C89 was 8.3 million ha with a production of 9.6 million tons. The area gradually decreased to current 5.36 million ha (2017¨C18) while the productivity has gone up with the total production of 8.94 million tons (FAO 2017).
  • How many countries grow groundnut?
  • Globally, groundnut is grown in more than 100 countries in an area of 27.6 Mha with a production of 43.9 million tons (FAO 2017). Groundnut has a unique and rare feature, geotropism, i.e. flowering, pollination, and hybridization happen on the aerial part followed by formation of a peg (gynophore) from the flower¡¯s pedicel.
  • Where do groundnuts come from?
  • The domesticated groundnut originated in the region of southern Bolivia and northwestern Argentina on the eastern slopes of the Andes (Simpson et al. 2001). About 95% of the total area is in the semi-arid tropics (SAT) (FAO 2017), where elevated high atmospheric temperatures in daytime often go beyond 35¨C38 ¡ãC.
  • What is the first linkage map of groundnut?
  • The first linkage map of groundnut was developed using RFLP markers in a diploid?¡Á?tetraploid cross (Kochert et al. 1996) comprising the A-genome of groundnut. The first linkage map covering all linkage groups of tetraploid groundnut was developed from a cultivated?¡Á?amphidiploid cross, with 370 RFLP markers (Burow et al. 2001).
