Peach season runs from May to September, which doesn't give yous much time to enjoy this sweet, juicy fruit.

Fortunately, there'due south a prepare: Freezing your peaches in the summertime will allow you to bask them throughout the year and brighten the tiresome, dark days of wintertime.

The best mode to freeze fresh peaches involves making sure the bright gilt fruit doesn't turn a dull brown, which occurs after slicing them.

Why Peaches Turn Brown

I of your primary priorities when freezing peaches will be to foreclose the beautiful fruit from turning brown. Commencement, it might be helpful to understand ​why​ peaches brown.

This browning procedure is one of the reasons peaches — along with bananas, avocados and apples — have such a curt shelf life when cut, according to the University of California, Davis.

When y'all slice a fresh peach, a group of enzymes known as polyphenol oxidases (PPOs) are activated by the exposure to oxygen. Through a rather complex procedure, these enzymes create highly reactive brown pigments chosen quinones, which are quickly oxidized, causing your one time bright, bang-up fruit to turn an unappetizing brown.

For the record, peaches turning brown on trees before they're picked isn't caused by the same chemical reaction as the dark-brown sliced peaches. Peaches that dark-brown on the tree are infected with brown rot fungus. Once infected, the peaches quickly turn brown and rot, making them inedible, according to Ohio State University Extension.

How to Keep Peaches From Turning Chocolate-brown

In lodge to keep peaches from browning, you'll desire to use some kind of anti-concealment treatment, per Colorado State University Extension. In that location are a few different solutions you lot can use, depending on your preferences.

Tip

Stop sliced peaches from turning chocolate-brown past calculation an acid — such as lemon juice, ascorbic acid or a commercial anti-darkening amanuensis made for fruit — immediately after cut them.

Vitamin C

Ascorbic acid is vitamin C that you can find at pharmacies and stores where canning supplies are sold. It helps preserve fruits' colour and flavor (it'll also add some vitamin C).

Ascorbic acid is available in powdered, crystalline and tablet form. You'll desire to dissolve the acid in cold water before using it to care for your peaches. Ascorbic acid is said to be the most effective agent for preventing browning.

There are several ways to use ascorbic acid to freeze peaches:

​1. Ascorbic Acid Syrup Packs:​ For syrup packs, dissolve 1/2 teaspoon crystalline ascorbic acid or i,500 milligrams vitamin C in each quart of cold syrup shortly before using. Stir information technology in gently so as not to stir in air. Refrigerate until set up to employ.

​2. Carbohydrate Packs:​ For this method, sprinkle 1/iv teaspoon crystalline ascorbic acid dissolved in 1/4 cup of cold h2o over each quart of fruit just before calculation sugar. Stir but enough to dissolve ascorbic acid.

​3. Unsweetened Packs:​ Sprinkle dissolved ascorbic acid over fruit, and mix thoroughly just before packing. If fruit is packed in water or juice, dissolve the ascorbic acid in the water or juice. This can exist a great selection for when you're using fresh (not frozen) peaches in a recipe and want to maintain their aureate hue.

​iv. Fruit Juices:​ Add ascorbic acid directly to the juice. Stir only enough to deliquesce ascorbic acid.

​5. Ascorbic Acrid Mixtures:​ You lot may be able to find commercial anti-darkening products, which tend to include ascorbic acid mixed with sugar. Follow the manufacturer'due south instructions for freezing peaches.

​half-dozen. Crushed Fruits and Fruit Purees:​ Add dissolved ascorbic acid to fruit preparation and mix.

Citric Acid or Lemon Juice

You can also apply citric acid or lemon juice to treat peaches prior to freezing, though neither solution will be constructive as ascorbic acid, per Colorado State University Extension.

1. Mix 3 tablespoons of lemon juice in each quart of cold h2o. Yous can also utilise 1/4 teaspoon crystalline citric acrid instead of lemon juice.
2. Dip the prepared fruit in the solution and let sit for one to ii minutes. Bleed and pack with h2o, sugar, syrup or fruit juice.

I gallon of citric acrid or lemon juice solution treats virtually i bushel of fruit.

How to Freeze Peaches Without Them Turning Brown

Peaches are available at their freshest for only a few months, then if you want to enjoy them across summertime, you can freeze them.

For platonic freezing conditions, select peaches that are firm and ripe. Sort, wash, pit and peel your peaches, so in halves, quarters or slices. You can skin peaches faster by using boiling water, per the Clemson Cooperative Extension.

1. Dip a few peaches at a time into boiling water for 30 to 60 seconds. Transfer the peaches immediately into ice h2o.
2. Now the skins should slip off hands. Cutting the peaches in half and remove the pit. Piece them into the size you like and care for them to prevent browning: with a vitamin C (ascorbic acid) and water solution
   • Put the sliced fruit into a water and vitamin C solution prepared at a ratio of six crushed 500-milligram vitamin C tablets to 1 gallon of water.
3. When all the peaches have been peeled and treated, bleed the water and sprinkle on 1/2 cup of sugar for each quart of peaches. Stir gently and let the fruit stand for 15 minutes. The peaches will brainstorm to make their own juice.
4. Pack the peaches into freezer numberless to inside iii to 4 inches of headspace at the elevation. Squeeze out the air, seal, label and freeze. You lot can also use rigid plastic containers. Go out about an inch of headspace earlier freezing.
5. When thawed, the peaches will take a softer texture than when they were fresh, but they will still taste smashing.

Y'all can follow the steps above, or yous can freeze peaches in a syrup mixture, per Colorado State University Extension. In this context, "syrup" is a mixture of sugar and h2o. Freezing peaches in carbohydrate is not necessary, but you'll still want to use some kind of anti-concealment solution (like the options above).

When you accept your peaches and syrup mixture prepared, do the following:

1. Oestrus peaches in humid 40 percent syrup for 1 to 2 minutes, depending on size of pieces.
2. Drain and cool peach pieces.
3. Pack in cold syrup and ascorbic acid mixture

Tip

If your peaches are not quite ripe plenty, place them in a newspaper pocketbook, pierce the handbag in several places, and set it bated at room temperature for a couple of days. Add an apple to the bag to speed up the process.

How to Make Sugar Syrup for Freezing Peaches

To make the syrup, dissolve sugar in cold or hot water.

If using hot h2o, absurd the syrup earlier using it. You tin can brand the syrup a day in advance and keep it covered in the refrigerator. You tin can replace up to 1/4 of the sugar with corn syrup or honey.

While you may non want the added calories of sugar mixed with your fruit, it's possible to adjust the corporeality of carbohydrate yous use. See the different proportions possible in the sugar syrup chart below.

Type of syrup (% syrup)	Sugar (cups)	Water (cups)	Syrup Yield (cups)	Calories per ii/three loving cup
10	1/2	four	4 1/2	57
20	1	4	4 three/4	108
30	1 iii/4	four	5	180
forty	ii 3/4	4	five 1/3	266
fifty	4	4	6	344

Colorado State University Extension recommends packing peaches in a cold, 30 to twoscore percent syrup, calculation 1/2 teaspoon crystalline ascorbic acid per quart of syrup.

Alternatively, y'all tin can pack peaches in cold water containing 1 teaspoon ascorbic acrid per quart of water.

Freezing Puréed or Crushed Peaches

Follow the instructions, from the National Center for Home Food Preservation, to safely freeze puréed peaches:

1. Coarsely trounce peeled and pitted peaches.
2. For purée, printing through a sieve or purée in a blender or food processor. (Heating pitted peaches for 4 minutes in just enough water to prevent scorching makes them easier to purée.)
3. Add ane/8 teaspoon of ascorbic acrid to each quart of fruit to maintain the integrity of the peaches.
4. Pack into containers, leaving 1 inch of headspace for every quart.
5. Seal the container and freeze.
