Sweet potato starch
Description
The process starts with peeled and cleaned sweet potatoes cut into small pieces and blended with water to create a smooth mixture. This blend is strained to separate solids from starch-rich liquid. The solids are washed to extract additional starch, which is then settled by resting several hours or overnight. After carefully removing the clear water above the settled starch, the starch is rinsed with clean water to ensure purity.
Finally, the starch is dried either in the sun or in an oven set to 50°C until fully dry. Well-dried sweet potato starch can be crushed into a powder suitable for various culinary uses such as thickening sauces, making noodles, or baking.
The key to quality starch is thorough washing, settling, and drying, which removes impurities like sand and color. This method produces a pure starch free from off-flavors.
Ingredients
- 1500g sweet potato skin already removed and completely cleaned, pure
- water as needed , I use around 7L
Instructions
- Remove the skin carefully and make sure no skin pumps attached, then cut into smaller pieces. Transfer to a blender, add water to cover the sweet potatoes. Blend until really smooth by batches.
- Strain the content to separate residue and the starch liquid. Wash the residue and strain to separate as more starch as possible.
- Set aside until the starch is settled (I recommend at least 4 hours resting).Remove the water gently above. Add around 1L water, mix well, repeat the straining and settling process (make sure no sand and other impurities contained).
- Set the liquid overnight (Note 1) (long resting time helps to remove the water content in the starch block) and pour off the water above. Here we get the pure sweet potatoes starch. Spread on a tray and dry under sun or bake in oven at 50 degree C until well dried.
- If you want to store the sweet potato starch, drying is extremely important. Well dried sweet potato starch can be easily smashed into powder.
Notes
- Ensure all sweet potato skin is fully removed to avoid bitterness in the starch.
- Repeat the washing and settling process until the water is clear to remove impurities.
- Dry the starch completely to a powder form for easy storage and use.
