On that can be used in the form of a high yield "Mizutoki" method, equivalent to the "glare" method of garment material, which has a crispy good texture, flavor, coloring without adversely affecting, a new clothing material It was an object to obtain. The starch is mixed with calcium and magnesium, and a puffed product is treated with an extruder, it is possible to use a specific gravity and particle size is within a predetermined range to "Mizutoki" batter flavor clothing material, and adversely affect the coloring without, it becomes a crispy unprecedented crispy texture.歩留りの高い「水溶き」法の形態で使用できる上に、「まぶし」法の衣材と同等の、クリスピーな良好な食感を有し、風味,着色に悪影響を与えることなく、新しい衣材を得ることを課題とした。澱粉にカルシウムとマグネシウムを混合し、エクストルーダーで処理した膨化物であって、比重と粒度が所定の範囲に入るものを「水溶き」バッターに用いることで、衣材に風味,着色に悪影響を与えることなく、従来に無いサクサクとしたクリスピーな食感となる。
