Steps to Produce White Plantain Flour

Select the Right Plantains

Choose green or unripe plantains, as they are less likely to brown during processing.

Peeling

Peel the plantains carefully. Soak the peeled plantains in a solution of water and lemon juice or ascorbic acid for a few minutes to minimize browning.

Cutting

Cut the plantains into thin slices, approximately 1/8 inch thick, to facilitate even drying.

Blanching (Optional)

Blanch the sliced plantains in boiling water for about 2-3 minutes. Although not strictly necessary, this step can help reduce enzymatic browning which can cause discoloration.

Drying

There are two primary methods for drying the plantain slices:

Dehydrator

Place the slices in a dehydrator set at a low temperature around 125°F (52°C) and dry until completely desiccated, which may take 6-10 hours.

Oven

Alternatively, dry the slices in an oven at the lowest setting around 140°F (60°C) with the door slightly ajar to allow moisture to escape. This method may require several hours.

Cooling

Allow the dried plantain slices to cool completely to room temperature. This step prevents condensation, which can lead to browning.

Milling

Once cooled, grind the dried plantain slices using a blender or food processor until you achieve a fine flour consistency.

Sieving

Sift the flour through a fine mesh strainer to remove any larger particles and ensure a uniform texture.

Storage

Store the flour in an airtight container in a cool, dry place. Consider adding an oxygen absorber to the container to maintain freshness and color.

Tips to Maintain Color

Work quickly and keep the plantains submerged in water with lemon juice if you’re not processing them immediately. Avoid exposure to air and light during the drying and storage processes to minimize oxidation. Ensure the plantains are fully dried to prevent moisture-related spoilage.

By following these steps, you can produce white plantain flour that retains its light color and is suitable for various recipes. Proper preparation and handling are key to achieving the desired outcome.
