Drying banana slices

2026-05-11

The drying process of banana chips is actually more complex than oranges or strawberries, because bananas have a high sugar content and a soft and sticky texture. If not processed properly, they can easily oxidize and turn black or become as hard as stones. There are two completely different styles of banana slices on the market: one is low-temperature fried (VF) banana slices with a crispy and oily taste, and the other is hot air dried banana jerky with a soft and glutinous taste that retains its original flavor.
The following are the detailed processes and key technologies of these two main processes:
🍌 Low temperature fried banana slices
This is the most common "banana slice" snack on the market, with a crispy texture and usually a sweet taste.
Core process: Vacuum low-temperature frying
Principle: In a vacuum state (reducing the boiling point of water), use oil as a heat transfer medium to fry banana slices dry at a lower temperature (80 ℃ -110 ℃).
process
Slicing: Cut the banana into thin slices of uniform thickness (about 2-3mm).
Color protection (key): Bananas are easily oxidized and turn black. After slicing, it is necessary to immediately immerse it in color protection solution.
Common color protectants: a mixed solution of citric acid, vitamin C, and saline solution. This can prevent enzymatic browning and maintain a golden color.
Blanching: Some processes involve short-term hot water blanching to inactivate enzymes and remove some starch.
Vacuum frying: Place the processed banana slices into a vacuum fryer, with a dehydration rate typically above 95%.
De oiling: After frying, remove excess oil from the surface using a centrifuge.
Seasoning: Spray syrup (to increase crispness and sweetness) or sprinkle salt according to taste.
Product features
Taste: Crispy, with a "click" sound when bitten.
Appearance: Golden yellow, with intact shape and no shrinkage.
Nutrition: Although retaining some nutrients, it has a high fat content (usually between 15% -30%) and high calories.
