Rice juice is a traditional Chinese drink that is usually squeezed from the leaves of the black rice tree. Black rice sauce has a rich aroma and unique color, and is widely used in cooking and baking. To preserve black rice juice for a long time, you can use the following methods:
Canned preservation: Pour the black rice juice into a clean glass or ceramic jar, making sure the bottle mouth is clean and free of water and oil. Close the lid and seal the mouth of the bottle with plastic wrap to reduce oxygen exposure. Place the jar in a cool, ventilated place, away from direct sunlight and high temperatures.
Cryopreservation: Pour the black rice juice into a clean glass or plastic bottle and add an appropriate amount of sugar or salt to inhibit bacterial growth. Place the bottle in an incubator or incubator and add ice cubes to create a low-temperature environment. Keeping it cold can slow down the spoilage process of black rice sauce.
Cryopreservation: Pour the black rice juice into a clean glass or plastic bottle and place it in the freezer compartment of the refrigerator. During the freezing process, the black rice sauce will solidify, but it will retain its original flavor after thawing. Note that the freezing process will cause the water in the black rice sauce to crystallize, which may change its taste.
Add preservatives: When making black rice sauce, you can add an appropriate amount of preservatives, such as potassium sorbate, sodium benzoate, etc., to extend the shelf life. However, it is important to note that an overdose of preservatives may cause adverse effects on the human body.
Regardless of the method, black rice sauce should be kept away from direct sunlight, high temperatures, and humid environments. At the same time, after each use of black rice juice, the bottle should be sealed in time to prevent air from entering and causing deterioration. Before drinking, check whether the black rice juice has any peculiar smell, discoloration or turbidity, and discard it in time if there is any abnormality.
