Soursop

Get to know soursop — a sweet-tart fruit rich in vitamin C and fiber. Nutrition facts, health benefits, and how to turn soursop into a refreshing juice.

What Is Soursop?

Soursop (Annona muricata) is a tropical fruit with green, softly spiky skin and fibrous white flesh with a refreshing sweet-tart flavor. Hidden inside the flesh are black seeds that must be removed before eating. Soursop trees grow easily in home yards in Indonesia, and the fruit is usually harvested when it's already slightly soft to the touch.

Its distinctive aroma and flavor — a blend of pineapple, strawberry, and a hint of citrus — make soursop a favorite for fresh juice. Besides the fruit itself, soursop leaves are also popularly brewed as herbal tea among Indonesians.

Health Benefits

  • Supports immunity — its vitamin C content helps maintain everyday immune function.
  • Good for digestion — its fairly high fiber content helps keep bowel movements regular.
  • Rich in antioxidants — phenolic compounds in soursop are believed to help fight free radicals in the body.
  • Helps maintain blood pressure — the potassium in it helps balance the body's sodium levels.

Ways to Enjoy Soursop

  • Eaten fresh — cut it in half, remove the seeds, then enjoy the soft flesh.
  • Soursop juice — blended with water and a little sugar or honey, the most popular refreshing drink.
  • Iced soursop — mixed with sweetened condensed milk and ice cubes for a refreshing cold drink.
  • Mixed into rujak (fruit salad) or fruit salad — pieces of soursop add a sweet-tart flavor to mixed fruit dishes.

How to Choose & Store

Choosing:
  • pick soursop whose spikes are already somewhat sparse and soft, a sign the fruit is ripe
  • press the surface of the skin — ripe fruit will feel slightly soft, not hard
  • avoid fruit with skin that has turned black or become watery, as these are signs it's starting to spoil
Storing:
  • soursop that's still somewhat firm can be left at room temperature for a few days until ripe
  • once ripe, store it in the fridge and finish it within 1-2 days since the flesh softens quickly
  • mashed soursop flesh can be frozen in the freezer as a juice stock for anytime use
Things to Keep in Mind
  • Soursop leaf tea or extract is often claimed by the public to cure cancer, but this claim has not been medically proven and should not be used as a substitute for a doctor's treatment.
  • Eating soursop in reasonable amounts as a fruit remains safe for most people.

Practical Tips

  1. Strain when making juice — soursop has quite a lot of coarse fiber, so strain it first for a smoother texture in the mouth.
  2. Remove seeds before blending — soursop seeds are hard and unpleasant if blended in.
  3. Add a little lime juice to soursop juice to balance out its sweetness.
  4. Freeze in small pieces so it's more convenient to grab as needed when you want to make juice.

Frequently Asked Questions

How can you tell soursop is ripe without cutting it open?
Gently press the surface of the skin — if it's slightly soft and the spikes are no longer stiff, that means the soursop is ripe and ready to eat. If it's still firm, it needs to sit for a few more days.
Is it okay to eat soursop seeds along with the flesh?
It's not recommended. Soursop seeds are hard and contain compounds that aren't good if swallowed in large amounts, so they should always be removed before the fruit is eaten or blended.
Can soursop leaf tea really cure serious illnesses?
There's no strong medical evidence supporting that claim. Soursop leaf tea can be enjoyed as an ordinary herbal drink, but it should not replace medical treatment for serious illnesses like cancer.
