Freeze Dried Soursop – Everything you wanted to know

Freeze dried soursop is a rare and usually food product indeed. As more and more people discover the wonderful benefits of soursop fruit and soursop leaves they start wondering what other foods come from the tropical fruit tree. The answer is freeze dried soursop fruit.

So what is freeze dried soursop fruit?

It is the soursop fruit pulp dried using a desiccating process called freeze-drying.  A low-temperature dehydration process is used on food products to remove water – it involves freezing the product, lowering pressure, then removing the ice by sublimation (ice turns into gas). This is in contrast to dehydration using heat to remove water. The freeze dried end product is pieces of soursop pulp that look like popcorn or chips. It is dry, crunchy, and sweet. But yet the freeze-drying process retains 99% of the nutrients compared to the fresh product.

Why do people eat foods made from the soursop tree, including its fruit and leaves?

The most famous compounds found in the tree. It is called acetogenin compounds (AGEs). Acetogenins block nicotinamide adenine dinucleotide, which is part of the membrane of cancer cells. Soursop has high concentrations of AGEs, found is in its fruit, stems and leaves.

Soursop fruit also contains many minerals, including calciummagnesium, and iron. In one cup of the fruit (or about 1/8 of a cup of freeze dried soursop) provides 46.4 milligrams (mg) of vitamin C in one cup of soursop pulp, which is over half the recommended daily amount for adults. For context, women need 75 mg of vitamin C per day, and men need 90 mg.

Advantages of  freeze dried soursop fruit

One of the challenges with soursop fruit is that it only grows in tropical and sub-tropical climates. You might see a soursop tree in Florida in the U.S., but even then it’s rare. The tree is very sensitive to temperature so if it gets cold enough to see frost on the ground then it means that a soursop tree will not thrive in that environment even if the rest of the year temperatures are in the 80s and 90s (25 to  35 C).

  • And some neurotoxic impacts.

Most of these side effects are a result of allergies or excessive or over-consumption of the tea. It is always wise to speak to your doctor of naturopath about potential risks or adverse reactions you may encounter with soursop tea.

What Is Soursop Tea?

In botany, the study of plants, soursop is known as Annona muricata. The tree is native to tropical regions of the Americas. The fruit, known to Spanish speakers as guanabana, can weigh more than five pounds.

While you can make chilled beverages from the pulp of the fruit, for tea, only the leaves are needed. This fruit has received a great deal of attention in recent years due to its apparent effects on cancerous activity in the body, but research is still ongoing for safety and efficacy of this tea. These effects of soursop are attributed to the presence of alkaloids, acetogenins, other antioxidants, vitamin A, vitamin B, vitamin C, calcium, iron, potassium, gentisic acid, and anonol.

Benefits Of Soursop Tea
Drinking soursop tea is a good idea for those suffering from hypertension, low immunity, inflammation of the skin, acne, obesity, low metabolic rate, indigestion, constipation, and anemia, as well as those who have been diagnosed with cancer and others at a high risk of developing cancer.

In the past decade, some remarkable research and claims about soursop tea’s ability to cure and prevent cancer have been made. This is largely due to the presence of acetogenins, a powerful group of antibiotics that have been found in this fruit. So far, the studies have shown positive results in connection to throat, lung, breast and cervical cancers, as well as leukemia. These effects range from shutting down the energy production capacity of cancer cells to causing apoptosis in these mutated cells.

Heart Health

High potassium levels and active compounds in soursop tea help to lower blood pressure by a significant amount. For people with hypertension, this is an excellent way to lower strain on the heart and reduce the risk of atherosclerosis, heart attacks, and strokes.


The good balance of vitamins and minerals, as well as anti-inflammatory compounds, can help aid the digestive system and prevent conditions of constipation, indigestion, cramping, bloating and diarrhea. The presence of calcium also helps the body uptake iron more effectively, while the antimicrobial effects of this tea will help balance the microflora environment of the gut. However, in excess, this tea can cause additional stomach upset and digestive problems.


The high level of iron found in soursop tea helps to stimulate the circulatory system and boost energy throughout the body. Iron is a key component of red blood cells, which bring energy to organ systems and tissues, speeding up repair and optimizing metabolic activity.
