Edible Uses

Edible Parts: Fruit  Oil  Seed
Edible Uses: Oil

Seed - raw or cooked. The large, soft, white kernels have a delicious, rich, almond-like flavour and are enclosed in a hard shell[63 , 200 , 301 ]. The seed contains over 60% fat[63 ]. The kidney-shaped kernel is usually well over 5cm long and 2cm in diameter[63 ]. The seed shell is about 7mm thick and difficult to crack[63 ]. The large fruit containing the seeds can weigh up to 11kg and measure 18cm in diameter, it contains 1 - 4 seeds (usually 1 or 2) which are easily extracted from it[63 , 200 ]. An edible oil is obtained from the seed[301 ]. Excellent for preparing bakery products[301 ]. Fruit - cooked[301 ]. The oily, yellow pulp is cooked and eaten as a vegetable[301 ].

Cultivation details

Management: Standard  Regional Crop  Staple Crop: Oil

A plant of the humid, lowland, tropical forests, where it is found at elevations up to 1,000 metres[335 , 418 ]. It grows best in areas where annual daytime temperatures are within the range 21 - 28c, but can tolerate 10 - 35c[418 ]. It prefers a mean annual rainfall in the range 1,600 - 2,000mm, but tolerates 1,200 - 2,400mm[418 ]. Grows best in a sunny position[418 ]. Prefers well-drained, light loams of good depth and fertile sandy soils[63 , 418 ]. Dislikes poor soils[63 ]. Plants are very susceptible to drought[200 ]. Prefers a pH in the range 6 - 6.5, tolerating 5.5 - 7[418 ]. Fruits take about 4 months to ripen from flowering[63 ]. Plants can take up to 20 years to produce their first crop from seed, though this can be greatly reduced by applying shade and wind protection when the plants are young[200 ].

Carbon Farming

  • Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
  • Regional Crop  These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.
  • Staple Crop: Oil  (0-15 percent protein, 16+ percent oil). Some of these are consumed whole while others are exclusively pressed for oil. Annuals include canola, poppyseed, maize, cottonseed, sunflower, peanut. Perennials include high-oil fruits, seeds, and nuts, such as olive, coconut, avocado, oil palm, shea, pecan, and macadamia. Some perennial oil crops are consumed whole as fruits and nuts, while others are exclusively pressed for oil (and some are used fresh and for oil).
