Its nutritional value will decrease over time
Unfortunately, even though you freeze your food properly, certain products can lose their nutritional value over time so you should pay attention to their odor, texture and color to figure it out.
“Food frozen in an ideal manner will always be safe to consume, but its quality, nutritional value, and flavor will decrease over time. Over time, the dry climate will zap food of its moisture,” says Palafox. “Keep an eye on color, texture, and overall physical appearance—as mentioned above—to see if they are still prime for eating.”
