First Giant Soursop (Annona muricata) fruits

As of the 25th of December 2018 we have had the first 60 Soursop fruits which are growing and starting to ripe now. When we first planted 100 different fruit trees, back in 2016, the soursop stood out because of its rocket like growth. Compared to the citrus fruit trees all of the Annona (Soursop, Rollina) and Artocarpus (Jackfruit, Breadfruit) fruit trees have grown extremely faster within our tropical climate. Later on we learned from a CEDAMAZ study that the Annona Muricata fruit is endemic to our Valley of the Fireflies (Valle de las Luciérnagas) here in the Zamora-Chinchipe region of Ecuador.

Did you know that the English name, “soursop” is derived from the Dutch “zuurzak”? Which means “sour sack”. In the German language the Soursop is known as “Stachel-Annone”. “Guanábana” is the local name in Ecuador.

The Soursop is a extremely tasty tropical fruit. With an average Brix value of unconcentrated natural fruit juice of 17.2° (degrees) it is sweet. It has flavors that are a combination of: Strawberry and pineapple, with sour citrus flavor notes that contrast with its creamy texture, which is similar to the flavors of coconut and banana.

Although the Soursop rind is quite bitter, the fruit’s flesh is soft, smooth and sweet. It provides healthy carbohydrates as its major nutrient. The soursop also contains a significant amount of vitamin C and several B1, B2, B3, B5, B6 vitamins such as thiamin, riboflavin and niacin. Along with a high amount of alkaline forming calcium, an important mineral for bone health.

The white pulp segments of the soursop fruit (75.6%) are primarily seedless, although it has an average of 171 seeds (5%) per fruit. Bark and seeds are toxic and contain poisonous alkaloids such as anonaine, muricine, and hydrocyanic acid. The seeds are also used for medicinal purpose of killing certain parasites.

The edible white pulp can be eaten raw. But it is also used to make fruit nectar, smoothies, fruit juice drinks, as well as candies, sorbets, and ice cream flavorings.

Research program on Amazonian Fruit from CEDAMAZ

Image: From CEDAMAZ – The Spanish name of the Annona muricata is Guanábana. In our region of Zamora-Chinchipe it grows within the 800 to 1000 m.o.s.l. It can’t grow lower than 800 m.o.s.l because its the lowest part of the valley base where the river Zamora flows. You can read

Not so long ago found some interesting data from the Nacional University of Loja in Ecuador (Universidad Nacional de Loja). It stated that a few years ago the CEDAMAZ started a research program about Amazonian Fruit (FRUTAMAZ). To identify, characterize and propagate the most promising native fruit species. With a focus on high nutritional importance as an agricultural crop alternative for the region.

Within this research program, at the end of 2010, the CEDAMAZ had identified, 31 promising fruit species originating from different corners of the province of Zamora-Chinchipe. The main species are: Moriche/Buriti palm (Mauritia flexuosa), Sacha Cherimoya (Rollinia Mucosa), Breadfruit (Artocarpus Altilis), Borojo (Borojoa Patinoi), Cacao Theobroma, Wild Cacao (Herrenia sp.), Camimito (Pouteria caimito), Peach Palm (Bactris Gasipaes), Cupuaçu (Theobroma grandiflorum), Guaba (Inga sp.) and last Soursop (Annona Muricata).

Steep Hill Tropical Agroforestry Soursop Zones

Between the soursop zones we have different food forest zones and lots Bamboo. As Ground cover we use Arachis pintoi – which is a great forage plant. Should help us in connection with the 15’000 Vetiver grasses matts we have planted within the access path to slowly improve the soil quality.

Giant Soursop Fruits come in all shapes and sizes

guanábana – 4m preparation finalized transplanting fruit trees

After more than 4 month of preparations and planning, this week we have been transplanting about almost 1000 guanábana tropical fruit trees. The plants seem to really like this climate and the geology of step hills here. Wikipedia: It’s tolerant of poor soil and prefers lowland areas between the altitudes of 0 metres to 1200 metres. It cannot stand frost. So in a nutshell perfect for our location at the edge of the amazonas region in Ecuador.

You have probably never heard of a guanábana fruit yet. It grows in many parts of the world and is known by many names. In the US&A it’s called “Soursop”. In Spain it is known as “Graviola”, in Ecuador and many other Latin American countries it is known as la ‘Guanábana’ (Annona muricata).

The flavour of the guanábana fruit is delicious – literally like a combination of strawberry and pineapple with an underlying creamy flavor of coconut or banana. Nothing less complex.

Although its rind is quite bitter, the fruit’s flesh is soft, smooth and sweet, and provides healthy carbohydrates as its major nutrient. Guanábana also contains a significant amount of vitamin C and several B vitamins such as thiamin, riboflavin and niacin, along with a high amount of alkaline forming calcium, an important mineral for bone health.

During the last 4 month we have been preparing this moment where we would finally transplant the Guanábana trees at finca PermaTree. Due to the fast growing pasture we had to clear cut the 3Ha all by hand before being able to make the specific measurements and then dig all of the holes for the plants. Then we found a high quality supplier for the needed amount of organic matter where we chose to mix two different types together. Every plant got about 1kg of organic matter. After one week of hard work among 7 we did it! Yeah.
