Abstract: The food drainage bag is a flexible drainage bag fabricated from a fine-mesh material having non-stick properties. The bag is utilized to drain excess liquid from frozen or fresh food items. Liquids can be made to drain more quickly from the foods simply gently by squeezing the bag. Alternatively, foods may be allowed to drain naturally if desired. The bag is easily cleaned and may be folded for storage or positioned on a hook to dry when not in use. The interior of the bag may be treated with a non-stick, non-toxic material to further enhance its non-stick properties.
