Can mulberries be eaten after being frozen?

Schisandra berries can be consumed after being frozen. Freezing inhibits bacterial growth and the activity of autolytic enzymes, thereby extending the shelf life of schisandra berries while preserving most of their nutritional content.

Schisandra is a common fruit rich in various nutrients. Foods high in water and carbohydrates, like schisandra, are prone to bacterial growth that leads to spoilage. However, the autolytic enzymes present in schisandra berries accelerate their decay. Storing them in the freezer can suppress both bacterial proliferation and enzyme activity. Aside from minor losses in texture and some oxidation-sensitive vitamins during freezing, the overall nutritional value remains largely unchanged.

Due to the fragility of cell walls in frozen schisandra berries, juice leakage is common. Therefore, they are suitable for making smoothies or used in boiled drinks and soups. This approach maximizes nutrient utilization and reduces waste caused by juice loss. Additionally, frozen schisandra berries can be used as ice cubes—for instance, added to slushes, smoothies, and other cold desserts.

It should be noted that frozen schisandra berries are considered raw and cold in nature due to their low temperature. Excessive consumption may disrupt gastrointestinal function and lead to discomfort such as abdominal pain, bloating, or diarrhea. It is advisable to avoid eating large quantities of frozen schisandra berries regularly. Individuals allergic to schisandra should refrain from consuming them to prevent allergic reactions.
