Extension Explores Preserving Apples

Fair Time in Tennessee!


2022 Fair Season has come to a close! I hope you had great success with your canning entries and won many blue ribbons! If you didn’t enter in your county fair this year, I hope you’ll make plans to enter in 2023. Remember to label and date your jars. 

Gardening Tips


Chris Hicks, Smith County Extension Agricultural Agent & County Director shares information on how its green time in Tennessee! 


If you haven’t pruned your fruit trees in a while, you may have noticed you have a tremendous amount of fruit that is small, misshapen, or diseased. In other words, you have poor quality fruit, but a lot of it!

Call me crazy but I prefer a smaller amount of high-quality fruit. Pruning during the dormant period this winter is a great way to thin next year’s crop while also improving the overall health and structure of your trees.

Properly trained and pruned trees will yield larger, higher-quality fruit much earlier in their lives and live significantly longer. Pruning should be done late in the dormant season, usually in February.

Pruning also improves air circulation and sunlight penetration which controls diseases by promoting rapid drying after rains and dews. Limbs that are broken, diseased, or insect-infested should be removed first. Low, drooping limbs should also be removed, as these generally produce poor quality fruit and may interfere with maintenance of the area under the tree.

Pruning methods vary based on the type of tree, so if you aren’t sure how to start, call your local UT Extension Agent for advice.

Safety Tips for

Preserving Apples


Storage and food safety

  • You can store apples in the refrigerator in a plastic bag with holes for ventilation. Store large quantities of apples in a cool place, between 32 and 40 °F. Properly stored apples will keep up to a month. Store canned apple products in a cool, dry area.
  • Wash hands before and after handling fresh produce.
  • Wash fruit thoroughly under cool running water. Do not use soap.
  • Keep apples away from raw meat and meat juices to prevent cross contamination.
  • For best quality and nutritive value, preserve only what your family can consume in 12 months.


Enzymes in light colored fruits such as apples, pears and peaches can cause oxidative browning as soon as the fruit is peeled or cut. To prevent the browning, the cut fruit should immediately be placed in an ascorbic acid (Vitamin C) solution as you prepare the rest of the fruit. When freezing apples in a sugar syrup, the ascorbic acid can be added to the syrup to prevent oxidation and the fruit sliced directly into the syrup. When dry packing frozen apples, the ascorbic acid is dissolved in a small amount of water and sprinkled over the fruit. Browning can also be halted temporarily by placing fruit in citric acid, lemon juice solutions or in a sugar syrup. However, these measures are not as effective as treatment with ascorbic acid in its pure form.


Apples, as well as other fruits, retain better texture and flavor if packed in sugar or a sugar syrup. However, sugar is not necessary to safely preserve fruit. Canned apples can be packed in water, very light syrup, light syrup or a medium syrup. Apples can be frozen in several ways. Sweetened apples can be frozen in a sugar syrup or they can be dry packed in sugar. Apples can also be frozen without any added sugar. Dry packed or unsweetened is generally the best method if using the apples for cooking and making pies as they contain less liquid than syrup packed apples.

Preserving Apples Selection


“An apple a day keeps the doctor away,” as the old saying goes. Apples may not keep the doctor completely away but can offer many health benefits. This fruit is very rich in fiber and antioxidants, especially when their peeling is still on. Eating apples has been linking to lowering your risk of developing many chronic diseases such as diabetes, heart disease, and cancer. Here are some tips to help make the best selection when picking your apples at the grocery store or Farmer’s Market or in your personal garden. 


  • Pick apples that are firm and crisp to the touch.
  • Apples should have no nicks or bruises. 
  • The skin of the apple should be smooth to the touch. 
  • Apples can come in all shades of reds, yellows, greens, and dual tones.
  • Remember to handle the apple with care to avoid causing bruising.  

Troubleshooting


What if my freezer stops running?

Our bountiful harvest has almost come to an end. No doubt you have spent countless hours preserving those delicious fruits and vegetables. You may have elected to freeze many of these items instead of canning them. What happens to all of that food if our freezer stops running? Ugh!!

When a freezer fails to work, the first rule of thumb is to keep the freezer door closed. In a well-filled freezer, food will probably remain frozen for about two days if the door is kept closed.

Are Your Apples Turning Brown?

Apples, when cut and exposed to air, darken quickly. Although browned apples are harmless,they lose their crisp texture. Below are recommendations for pretreatment to prevent browning:


Ascorbic Acid (Vitamin C): Available in powder or tablet form and typically found with other food preservation supplies in the grocery store or a

drug store. One teaspoon powdered form is 3,000 mg or six-500 mg tablets. White specks in the tablets are harmless. How to Use: Mix 1 teaspoon powder (6 crushed tablets) in 2 cups water. Place fruit in for 3-5 minutes. Remove and drain. After used for two batches of fruit, add more acid.


Ascorbic Acid Mixture (Vitamin C): Contain ascorbic acid and sugar. Used for fresh fruit for canning and freezing. How to Use: Follow the manufacturer's instructions


Honey Dip: Fruit can be sold dipped in a honey solution. This method adds extra calories to the fruit. How to Use: Mix ½ cup sugar with 1 ½ cup boiling water. Add ½ cup of honey. Let the fruit soak in solution for 3-5 minutes. Remove and drain.


Fruit Juice Dip: Using a fruit juice high in vitamin C such as orange, grape, cranberry,pineapple, lime, or lemon juice can also slow down browning. Different juices will add differentcolors and flavors to apples. Tip: Mix 3 tablespoons lemon juice: 1-quart water How to Use: Add enough juice to cover apples. Soak 3-5minutes. Remove and drain.

After cooking the bacon, add onion, celery and sugar to the reserved 2 tablespoons bacon fat in the skillet. Cook over medium high heat, stirring frequently, until the onions become translucent and caramelize to a medium brown. Add vinegar, apples, thyme, salt, ginger, cinnamon and mustard. Cook until most of the liquid is evaporated. Let cool. Stir together the cheeses and spread over the crostini. Top with apple mixture and bacon.
