Fresh rice (within 1 month after milling stored in a refrigerator) and degraded rice (more than 6 months after milling stored at room temperature) were imaged and compared using OCT-SS-01.
Although no significant differences were observed with the naked eye, the differences between fresh and degraded rice could be observed when compared with OCT-SS-01 images.
①Projection image
The "cracks" caused by dryness, which cannot be seen with the naked eye, could be observed clearly.

②Cross-section image
In the degraded rice, we found that "cracks" and "stains" that could not be seen with the naked eye or projected images reached the inside of the rice.
