remaining time/shelf life Grade of freshness
＜0 Has expired
0～0.3 Quick expiration date
＞0.3 Fresh and fresh
As another example, the preset ratio corresponds to the freshness level as shown in the following table:
remaining time/shelf life Grade of freshness
＜-0.3 Severe expiration
-0.3～0 Has expired
