Method of reducing the content of phytate and high degree of phytase in cereals and cereal products having a reduced content of phytate

摘要

A method for reducing the content of phytate and/or salts thereof, formed by phytic acid, in cereal grains, whereby the cereal grains are subjected to a combined wet steeping and dry steeping in at least two successive cycles in that the cereal grains are mixed with water or a water mixture to a water content in the cereal grains of 25- 60%, the pH value is adjusted to pH 4-7, the mixture is heated to 35- 60° C. and is subjected to wet steeping for a period of 0.5-10 hours, eventual excess of water or water solution is drained, and the cereal grains are dry steeped for a period of 0.5-20 hours at a temperature of 35-60. degree. C., whereupon the cereal is finally dried. The cereal can be taken out of the process as whole grains, as flakes, as cut grains or as flour.
