A method for producing a puffed food product which comprises subjecting a food selected from the group consisting of cereals, fruits, vegetables, fish and meats (whether red or white), formulated protein, formulated carbohydrates, formulated fat, any combination thereof and including gelled formulations thereof to a diffusive gas environment (preferably CO2 under pressure) when said food is at an intermediate moisture level for sufficient time for gas infusion into and preferably throughout the food, thereafter further drying the food and, when the food stuff is at a desired lower moisture content, placing the food in an environment and/or otherwise treating the food to prevent a substantial adsorption of moisture by the food. The invention also consists in a puffed food product of a moisture content less than 5% by weight that has been prepared from a food selected from the group consisting of cereals, fruits, vegetables, fish, meats (whether red or white), formulated protein, formulated carbohydrates, formulate fat, any combination of any of the foregoing and including gelled formulations thereof the volume of which is not substantially less than the volume it has assumed at an intermediate moisture level, the structure of the food being maintained or expanded by a gas impregnated into the food using a gas environment of at least atmospheric pressure prior to subsequent drying to the desired final moisture content at which it is to be stored. |
