Definitions

• the present invention relates to methods for the treatment of foodstuffs using support materials.
• the preparation of foodstuffs often involves multiple processing steps such as freezing, storing, thawing and heating. It is important throughout all of these steps that exposure to the environment be kept to a minimum to avoid the possibility of bacterial contamination. It is thus preferable to keep the food in a single support material, such as a container bag, at all times prior to final preparation for consumption.
