(e) The antioxidants BHA and BHT are the preservatives most often added to prevent them from becoming stale and rancid. 

  • Preparing the grain: Grain is received at the factory, inspected, and thoroughly cleaned. 
  • Making wheat flakes: Cleaned grains are tempered in bins and subsequently steamed at atmospheric pressure until they attain moisture of 21%. The steamed wheat is passed through steam rollers which ruptures the bran coat and flatten the whole grain thus making the kernels more permeable to moisture during the cooking step. The flattened kernels are then cooked in rotating retorts along with malt, salt, sugar etc. for 90 min at 20 psi steam pressure. The resulting flakes are conveyed to ovens where they are tossed in a blast of very hot air to remove remaining moisture and to toast them to a desirable color and flavor with less than 3% moisture. 
  • Adding coatings: After shaping, the wheat flakes may be coated with vitamins, minerals, sweeteners, flavors, food colors, or preservatives. Packaging and storage: Prepared flakes are packed in suitable moisture proof container of suitable size. Later they stored in cool and dry place
