* Adding some sugar.

* Consider just sealing the sugarcane juice and placing it inside the freezer of the refrigerator.

But even then, after 8 months of freezing, the sugarcane juice may still be discolored when thawed, as the long period of time can lead to some material losses and changes. Overall, to better maintain the freshness and color of sugarcane juice, you can minimize the storage time and consume it as early as possible.
