Abstract:
A method of reducing the content of phytate and/or its salts formed by phytic acid and/or high contents of phytase in cereal grains, wherein 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 solution, the pH value is adjusted to pH 4-7, the mixture is heated to a predetermined temperature and is subjected to a wet steeping for a period of 0.5-10 hours, eventual excess of water or water solution is drained, and the cereal grains are subjected to a dry steeping for a period of 0.5-20 hours at a predetermined temperature, so that the water content of the hydrothermally treated cereal grains is 25-60%, whereupon the cereal grains are finally dried.
