Vacuum frying at a temperature below 100 degrees Celsius produces crispy, delicious bananas that retain their flavor, color, aroma, and nutritional value very well. In addition to bananas, there are many other vacuum-fried fruits and vegetables such as mangoes, jackfruit, pumpkins, carrots, okra, watermelon, lychees, and longans. Products that have gone through the vacuum frying process can be stored for up to 1 year.
