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.
