How we tested spoilage

We tested the spoilage of mixed frozen berries by first storing them in our freezer at a consistent temperature of 0°F (-18°C). We held both opened and unopened samples for a total of six months, carefully observing them for any signs of spoilage. Upon inspection, we noted the presence of ice crystals and some clumping in the opened package, while the unopened berries appeared slightly discolored but otherwise intact. We also checked for off odors, which were absent. After a quick cook test, heating the berries to 165°F (74°C), we ultimately decided to discard anything that showed even slight signs of freezer burn or questionable appearance, prioritizing safety above all.
