1. It is recommended to refrigerate shredded mozzarella cheese. Just refrigerate, but it's best to seal and refrigerate. Wrap it in tin foil or plastic wrap and refrigerate it to keep it for a long time. Freezing will not only cause fat separation, but also lose the nutrients in the cheese and affect the taste.
2. In order to preserve the cheese in the best condition, you must store and handle it appropriately immediately after you buy it home. Generally speaking, if unopened cheese is stored between 1°C and 3°C, the quality will remain unchanged. Generally, it is no problem to store it for a week.
