    • Precooked and partially debranned corn flour is continuously produced by an enzymatic precooking using a commercial endoxylanase and endoamylase blend as a processing aid. The low-temperature and near neutral-pH precooking with an endoxylanase and endoamylase solution effects a partial hydrolysis of bran and starchy cell-walls with a controlled gelatinization and reduced conditioning and corn solid loss in wastewater. Moisture content is then stabilized after washing, followed by milling and drying at a high temperature for a short time to produce a partial gelatinization in the ground kernel, cooling and further drying the dried-milled particle. A fine particle size or flour is separated and recovered from the coarser particle which is also segregated to isolate a light bran fraction for integral flour or feed use, remilling and sieving the coarser particle to produce an instant corn flour for snack chip and corn-based food, and admixing the fine particle with lime to obtain a masa flour for tortillas and the like.
    • 使用商业内切木聚糖酶和内切淀粉酶混合物作为加工助剂,通过酶预预煮连续生产预煮和部分脱壳的玉米粉。 用内切木聚糖酶和内切酶酶溶液进行低温和接近中性pH预煮,可以控制糊化,并且减少了废水中的调理和玉米固体损失,从而部分水解了麸皮和淀粉样细胞壁。 洗涤后水分含量稳定,随后在高温下研磨和干燥短时间,以在研磨的核中产生部分糊化,冷却并进一步干燥干燥的磨碎颗粒。 细粒度或面粉从较粗颗粒分离并回收,粗颗粒也被分离,以分离用于整体面粉或饲料用途的轻糠级分,对较粗颗粒进行再搅拌和筛分以产生用于小吃片和玉米基的即食玉米粉 食物,并将细颗粒与石灰混合,得到玉米粉饼等的马萨粉。
