Food Profile: Jackfruit

Jackfruit, or Langka as we call it is a unique and delicious tropical fruit which grows abundantly here in the Philippines. The ripe fruit is very large, sometimes reaching up to 5 feet in length! When opened it has a number of sweet, yellow rubber-like pods that contain seeds, which are often already germinating. Compared to other fruits, Jackfruit has a high protein content of 3% and also a lot of carbohydrates. Because of this, unripe fruits are often used as meat substitutes for vegetarians. Aside from protein, Langka also provides a very balanced supply of vitamins, antioxidants and minerals.

Special Information

Langka is a wonderfully versatile fruit which can be used in savory dishes and eaten fresh as well. I have not been able to find nutritional values of unripe Jackfruit, but it likely has small variations. Seeds from the ripe fruit should be put in a shallow dish of water immediately after eating if you intend to plant them. Wait for the small root to come out and then plant the seed in a seedling bag about 1’ deep. Jackfruit trees usually fruit within 5-7 years.

Choose Organic

As far as I know, Jackfruit is generally grown organically. The fruit is not easily attacked by pests and the tree is able to grow without much fertilization. The only pests that Jackfruit has are birds which are able to penetrate the thick skin with their beaks. Fruit flies can also be an issue but wrapping it in a sack can deter them. As always it helps to ask, as those grown as side crops in conventional orchards may have some pesticide drift residues.
