Amazing facts about Tiger nut oil

tiger nut

I have never associated Tiger nut with oil, never. Tiger nuts, Cyperus esculentus, sedge, chufas (Spain), aya (hausa), imumu/ofio (yoruba), aki awusa (Igbo) are those tiny nuts, that are not really nuts sold by street vendors in their wheelbarrows on Nigerian streets, alongside dry dates and kuli-kuli. Crunchy, sweet and juicy, they are actually tubers.

Munching the fresh or rehydrated dry tiger nuts, drinking tiger nut milk, even making the flour and using it in delicious recipes, these are things I do with tigernuts, but tiger nut oil? I was totally blown away and happy I came across it. I have said to myself anything that comes from tiger nuts must be good and delicious, I need to buy tiger nut oil from konga.com.

All plants contain oils or fats example, olive oil and cocoa butter but mainly in their seeds, tiger nut is for the time being the only known plant that accumulates oil in a substantial amount in its tuber/root (up to 27% oil). This oil is very versatile in its usage and for each way it is used, it ranks superior. For cooking, hair, skin, as biodiesel etc.

Tiger nut oil can be purchased online on Konga.com

  • Tiger nut oil has a very long shelf life, it does not go rancid fast because the oil is extremely resistant to oxidation.
  • It has a higher oxidative stability than other oils, due to its low content of polyunsaturated fatty acid, high content of vitamin E and other antioxidants.
  • Tiger nut oil is resistant to chemical decomposition at high temperatures so is good for high-temperature cooking.
  •  It is a heart-healthy oil with a high Vitamin E content.
  • Tiger nut oil has a similar lipid profile as olive oil ( see table above ).
  • It predominantly consists of oleic acid. Other major fatty acids present are palmitic acid, linoleic acid and stearic acid.
  • It has a balanced ratio of calcium, potassium, phosphorus, magnesium, manganese, copper, zinc and iron.
  • Tiger nut oil is a good source of B vitamins, vitamin C and E.

  • Tiger nuts oil is also cholesterol free and has very low sodium content.

Culinary/Nutritional properties of Tigernut oil

  • Tigernut oil is considered a stable oil which remains in a uniform liquid form at refrigeration temperature making it suitable as a salad dressing and vegetable based ice-cream.
  • It has a higher smoke point than olive oil, so ideal for high-temperature cooking like deep frying, stir-frying etc.
  • Due to its extraction by a cold, virgin process, tiger nut oil retains all its unique nutritional qualities.
  • Highly recommended for cooking above other oils because it is more resistant to chemical decomposition at high temperatures.
  • Less fat is absorbed into the food as tigernut oil creates a crust on the surface of the food during cooking, preventing the oil itself being absorbed into the food.
