Kiwi is a difficult fruit to dry, because if dried incorrectly, the structure and internal nutritional value of the kiwi fruit will not remain intact.
If we dry using the hot drying method – a dryer with a high temperature above 50 degrees Celsius, the vitamin C in kiwi fruit is easily changed, and the kiwi flesh will not have the original shape and characteristics. As for freeze drying, the cost is too expensive and higher, so not everyone can easily invest.
