Preparing Apples for Freezing
Before freezing, apples need to be prepared to ensure they retain their quality. The preparation steps include washing, peeling (optional), coring, and slicing or chopping the apples into the desired size and shape. It’s also important to remove any bruises or damaged areas, as these can affect the texture and flavor of the frozen apples. For some freezing methods, an additional step of soaking the apple pieces in a solution to prevent browning may be necessary.
Preventing Browning
Apples contain an enzyme called polyphenol oxidase, which reacts with oxygen in the air to turn the fruit’s phenolic compounds into brown pigments, causing browning. To prevent this, you can soak the apple pieces in a lemon juice and water solution or use commercial anti-browning products. Ascorbic acid (Vitamin C) is also effective in preventing browning and can be used in the form of crushed tablets or powder mixed with water.
Methods for Freezing Apples
There are several methods for freezing apples, each suited to different uses and preferences. The choice of method depends on how you plan to use the frozen apples and the equipment you have available.

Put the sheet in the freezer and let the apples freeze solid, which can take several hours. Once frozen, transfer the apples to airtight containers or freezer bags, making sure to remove as much air as possible before sealing. Frozen whole apples are best used in cooked or baked dishes, such as pies, crisps, or sauces, where their texture won’t be a major issue.
How Do I Prepare Apples for Freezing?
Preparing apples for freezing involves several steps to ensure they retain their flavor, texture, and nutritional value. The first step is to wash the apples thoroughly to remove any dirt, wax, or bacteria. Then, peel, core, and chop the apples into the desired shape and size, depending on their intended use. It’s essential to remove any seeds, stems, or leaves, as they can be bitter and affect the flavor of the frozen apples. You can also add a sprinkle of lemon juice or ascorbic acid to prevent browning and preserve the apples’ color.
To prevent the apples from becoming brown or developing an off-flavor, it’s crucial to blanch them in boiling water or steam for a short period, usually 1-2 minutes. This step helps inactivate the enzymes that cause browning and spoilage. After blanching, immediately plunge the apples into an ice bath to stop the cooking process and preserve their texture. Once the apples have cooled, pat them dry with paper towels to remove excess moisture, which can lead to freezer burn or the formation of ice crystals. Then, package the prepared apples in airtight containers or freezer bags, making sure to remove as much air as possible before sealing.
