Banana chips are a common snack with a crispy texture. Their making process involves a series of processing steps, we will introduce the banana chips making process step by step here.
Step 1: Washing and Peeling
As the raw material, bananas must first be cleaned to remove surface dirt and impurities before processing begins. After washing, peeling is required. Due to their curved shape and significant variations in length and thickness, mechanical peeling presents challenges and risks damaging the fruit flesh. Therefore, in actual production, most factories still rely on manual peeling to ensure the integrity of the flesh and minimize raw material loss.
Step 2: Slicing
Peeled bananas proceed to the slicing process, where they are cut into uniformly thick circular slices. The thickness of banana slices is typically controlled between 2–4 millimeters.
Step 3: Color Preservation Treatment
Bananas are rich in polyphenols and undergo enzymatic browning very easily after slicing, causing discoloration. Therefore, the slices are soaked in an antioxidant solution to preserve their color.
Step 4: Frying
Frying is the core process determining the quality of banana chips. Oil temperature is typically maintained between 160°C and 180°C. Frying time is adjusted based on slice thickness and equipment performance, generally ranging from 2 to 5 minutes. During frying, moisture rapidly evaporates from the interior of the banana slices, forming a porous structure that yields a crispy texture.
Step 5: De-oiling
There are two methods for de-oiling banana slices: centrifugal de-oiling and vibratory de-oiling. Both methods aim to remove excess oil from the surface of the banana slices.
Step 6: Packaging
Banana chips are typically packaged using nitrogen-flushed packaging. This not only prevents moisture absorption and oxidation but also reduces breakage during transportation.The above outlines the primary process for producing fried banana chips. If you wish to produce sugar-coated banana chips, a sugar-coating step must be added before color retention or frying. Other steps and the banana chips processing equipment involved remain largely unchanged. For more detailed information, please feel free to leave us a message.
