Corn food gradually got a good reputation due to its anti-cancer advantage and rich in micro elements.Deep corn processing machinery can produce varieties of corn products. Following is introduction of positive ion starch technology.

① To take wet milling as an example, positive ion starch is processed as follows.

It is reacted in alkaline condition with water added to some inorganic salt to prevent starch from swelling. For example, gasification sodium or sodium sulfate anti-swelling agent 10-20; common slurry concentration35-40；temperature 40-55; medium 11-11.5; reaction time 4-24min.After reaction, hydrochloric acid is used to neutralize to PH 9.4-5. Then the starch is centrifuged, washed and dried.

② Reaction is affected by molar ratio of alkali and etherifying agent, temperature, duration, concentration.
