As of the 25th of December 2018 we have had the first 60 Soursop fruits which are growing within the Finca Yantza food forest 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 an 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
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).
