QUALITY DETERMINATION DEVICE

A quality determination apparatus includes a state detector and a main processing unit. The state detector detects a state index. The state index is an index indicating a state of a target article contained in a storage space where an internal environment is controlled. The main processing unit performs a determination operation. The determination operation is an operation of determining whether a sign condition indicating a sign of degradation of the target article is met based on the state index detected by the state detector.
