The present invention includes puffed-food starch material snack, in particular starch material from grains, having an improved crispy texture and a more aesthetic appearance and methods for preparing them. In general terms, the products are snack chips, cakes, crackers or the like, made from food starch material. Preferably, the starch material is provided primarily in the form of individual kernels or pellets of a cereal grain, such as rice, corn, wheat, rye, oats, millet, sorghum, barley, buckwheat, or mixtures thereof. Quantities of other food starch material es may also be employed as a co-mixed constituent, or the primary source of bulk starch material, for example potato starch material. A quantity of the grain is puffed (expanded) in a manner which forms a snack product of considerable crispiness, lightness, and unique texture to both the mouth and eye. According to a method of making the puffed food starch material product of the present invention, a puffing chamber is provid ed having inner surfaces and a chamber volume. A bulk amount of the food starch material is placed into the puffing chamber. The bulk amount of food starch material is caused to volumetrically expand. The expanding food starch material is constrained in its expansion in at least a first dimension, while permitting expansion of the bulk amount in at least a second dimension.La presente invención se refiere a un producto de bocadillo inflado que comprende: un cuerpo de material de almidón inflado unitario, en donde dicho cuerpo de material de almidón inflado comprende una pluralidad de pellas infladas individuales de al menos dos tipos, en donde cada tipo de pella ha sido expandida por un grado diferente.
