Alpha Rice is a unique rice that is perfectly steamed and then dried, so you can make delicious rice dishes simply by adding hot or cold water. No steaming required!

What is Alpha Rice?

The "Alpha" in "Alpha Rice" refers to the state of the starch contained in the rice. Rice is made up of 70% to 80% starch. Raw starch (raw rice) tastes bad when eaten as is, but when you add water and heat it, it turns into delicious and easily digestible starch. This is called "gelatinization," or "alpha modification."
If you rapidly dry Alpha modified rice and remove the moisture, the starch does not return to raw starch, and instead remains as alpha modified starch.
Then, you can just add hot water to this Alpha Rice to make a succulent, delicious rice dish without the need for steaming.

Alpha Rice can easily be stored for long periods of time, so it is good as emergency food to prepare for disasters, and makes an excellent portable food for international travelers or mountain climbers. It has a broad range of uses.

The rice can be stored for five years at room temperature.
The expiration date is large and easy to read.
Make supple rice in just 15 minutes with hot water, or 60 minutes with cold water.
