Water vapour generating device for use with packaged food when microwaved

摘要

A device to prevent drying out of packaged food when microwaved comprises hydrated Bentonite clay within a permeable container such as a sachet to release water vapour when exposed to microwave radiation. The fully hydrated clay may correspond to one part by weight in the dry form thereof per at least five parts of water. Hydration of the clay may occur by adsorption of drip loss fluid from the food in the package prior to microwaving; and/or by previously placing the sachet in water for at least 30 minutes. The sachet is liquid and gas permeable and may also contain polyacrylate beads and flavourings. The food packaging may be self-venting when microwaved.
