Fruit may also be frozen unsweetened in a liquid pack. Pack it in its own juice, water or juice from another mild-flavored fruit. With light-colored fruit, more ascorbic acid should be added to keep fruit from darkening when sugar is not used. Back To Top Artificial Sweeteners Artificial sweeteners give a sweet taste but do not furnish the other benefits of sugar, such as color protection or thickness of syrup. Fruits preserved with artificial sweeteners will freeze harder and thaw more slowly than fruits preserved with sugar.
Some artificial sweeteners provide a bitter taste to fruits after extended storage.
Therefore, you may prefer to freeze fruits without added sweetener and add an artificial sweetener when the fruit is served. Use the directions on the sweetener to decide the amount to use. Packaging and Containers Packaging is very important in freezing to insure that the quality of food is maintained. A vacuum seal is not necessary, but the package must be air tight. You cannot expect perfect results if you use ordinary foil, wax paper, thin plastic wrap, or similar materials.
