    • A process for making fried expanded snack products includes preparing a moist dough principally from solids, such as corn or potato solids. Larger particle size dry food particles, such as wheat or rice particles, are included in the dough. The dough is then formed, such as by rollerforming, into a thin sheet, and dough pieces cut from the sheeted dough are fried in hot cooking oil to form a fried expanded snack. The larger food particles project through or are contained in the surface of each dough piece to cause steam to escape during frying, which greatly reduces "puffing", i.e., formation of undesired bubbles in the snack, during frying. By providing a sufficient number of larger particles with an average particle size at least about to the thickness of the dough piece (so that an appreciable number of particles can project through or be contained in the surface of the dough piece), formation of undesired large bubbles is significantly reduced. The size of the largest bubbles formed during frying is proportionately reduced as the amount of larger particles added to the dough is increased. Formation of bubbles larger than a maximum tolerable size can be controlled to within acceptable limits by adding particulates greater in particle size than the dough thickness and in an amount that results in at least one particle per unit surface area of the sheeted dough piece, where said unit surface area is the largest acceptable size (area) of any bubbles formed during frying.
    • 制作油炸膨化零食的方法包括主要从固体如玉米或马铃薯固体制备湿面团。 较大粒径的干粮颗粒,如小麦或米粒,被包括在面团中。 然后将面团例如通过辊压成型形成薄片,并将从片状面团切割的面团片在热烹饪油中煎炸以形成油炸的膨化小吃。 较大的食物颗粒通过或被包含在每个面片的表面中以使得蒸汽在油炸期间逸出,这在油炸期间大大减少了“膨化”,即在小吃中形成不期望的气泡。 通过提供足够数量的具有至少大约面团片的厚度的平均粒度的足够数量的更大的颗粒(使得可观察到的颗粒数量可以穿过或包含在面片的表面中),形成不期望的大的 气泡明显减少。 随着添加到面团中的较大颗粒的量增加,在油炸期间形成的最大气泡的尺寸成比例地减小。 通过添加比面团厚度更大的颗粒大小的颗粒和导致片状面团的每单位表面积的至少一个颗粒的量,可以将大于最大可容许尺寸的气泡的形成控制在可接受的限度内,其中所述 未表面积是油炸期间形成的任何气泡的最大可接受尺寸(面积)。
