Does frozen food keep longer if frozen at colder temperature or does the frozen state preserve it whether it is frozen at -40 F or -100 F?

Frozen food generally keeps longer at colder temperatures, as lower temperatures slow down the chemical reactions and microbial activity that can lead to spoilage. While food remains frozen at both -40°F and -100°F, the colder environment can better preserve texture and flavor over extended periods. However, the difference in preservation quality becomes less significant at extremely low temperatures, as both can effectively halt spoilage. Ultimately, while freezing at lower temperatures can provide slight advantages, the key factor is that food remains consistently frozen.
