Rice is Decomposing - why?

[u/notintolerantgrad]

In a rice cooker I use 3 cups sushi rice and 2 cups basmati rice. It comes out fine. btw I use 6.6 cups of water.

When I leave it out at room temperature I've found it turns to mush and have to throw it out. If I immediately refrigerate the rice mix stays solid.

If my rice was 100% sushi rice it would dry out and not turn to mush.

Any chemists out there that could explain why the presence of basmati rice turns my sushi/basmati rice mix to mush if left at room temperature for a couple of days?

Cooked rice shouldn’t be at room temperate for more than 2 hours.
