Decrease potato shrinkage by implementing proper storage techniques and reducing exposure to light and air.

• Store potatoes in a cool, dark, and well-ventilated place to prevent sprouting and shrinkage.

• Avoid washing potatoes before storing as moisture can lead to faster spoilage.

• Handle potatoes gently to prevent bruising and damage, which can accelerate shrinkage.

• Use proper packaging such as breathable bags or containers to maintain optimal humidity levels.

• Regularly inspect sto...read more
