Intelligent 4-stage cooking process optimizes temperatures, moisture, and time to ensure unhealthy Rapidly Digested Starch (RDS) content is discarded.

Rice Gelatinization Temperature and RDS Removal

Optimal Water Heating and Rice Boiling by Grayns

Grayns removes yellowness of rice caused by high glycemic indexes of standard cookers.

Stage One: Thermosense — Slowly gelatinizes rice at precise temperatures to release unhealthy Rapidly Digested Starch into water while retaining nutrients.

Stage Two: Debond — Holds the optimal boiling and gelatinization temperature, compelling most of the unhealthy Rapidly Digested Starch out of the rice.

Grayns Rice: Unhealthy Starch-Rich Water Removal

Optimal Drainage and Demoisturization by Grayns

Grayns cooked rice lasts 5 days longer from RDS removal which ferments in less than 24 hours.

Stage Three: Transude — Unhealthy Rapidly Digested Starch is transuded through rice to be drained away into the Gryans starch collection tray underneath.

Stage Four: Demoisturize — Finally, Grayns demoisturizes the excess healthy water from the healthy cooked rice to make it fluffy and delicious.
