International Classification:

A21D 2/00

US Classification:

426622000

Abstract:

A process and apparatus for the continuous production of pregelatinized corn flours for dairy-based and cereal-based foods, includes an acid precooking with a sodium metabisulfite, or sodium hydrogen sulfite or sodium sulfite solution as a food processing aid for partial hydrolysis of insoluble fiber, starch and protein, along with a controlled pregelatinization and denaturation, kernel washing, stabilizing moisture content for grinding, milling and drying preconditioned kernel to produce a partial gelatinization, cooling and drying the dry-ground particle, separation and recovery of the ultrafine grind from the coarser grind while the latter is further aspirated to remove a light corn bran and further reground to produce bran flour, remilling and sieving the isolated coarser grind to obtain fine corn flour for cereal-based foods, and admixing only fine flour with lime to produce a masa flour. An ultrafine corn flour is used as an aid or adjuvant flour for dairy-based foods.

International Classification:

A23L 100

US Classification:

426508

Abstract:

Precooked and partially-dehulled corn flour is produced using an acid-cooking in a continuous process, by acid-precooking to effect corn hull hydrolysis with sodium metabisulfite or sodium hydrogen sulfite or sodium sulfite, with reduced kernel washing and solid loss. Moisture content is then stabilized, followed by grinding and drying in a super-heated stream of air, cooling and further drying the dried-ground particle. A fine grind or flour is separated and recovered from the coarse grind which is also segregated to isolate a hull fraction as corn hull waste, regrinding and sieving the coarse grind to produce an instant corn flour for arepa, and admixing the fine grind with lime to obtain a masa flour for tortilla and the like.
