With warming temperatures and extended daylight hours, a growing number of Britons will be turning to fresh produce to enjoy seasonal favourites like strawberries, raspberries, apricots, and plums. While stocking up on an abundance of vibrant fresh fruit is desirable, the drawback lies in its limited shelf life, with containers often deteriorating quickly. Peaches, in particular, are susceptible to browning almost immediately upon slicing, a result of their reaction to oxygen.
Combatting Browning in Sliced Peaches
A Simple Kitchen Solution
Food scientist and blogger Jessica Gavin has revealed a simple method using a common kitchen staple to keep sliced peaches looking appealing. According to Gavin, the secret to preserving peach slices is lemon juice. A generous application provides “natural acidity” that effectively inhibits the enzymatic process that causes browning when peaches are exposed to air.
The Science Behind Browning
“When peaches are cut, they are exposed to oxygen. This contact triggers a reaction that produces an enzyme called polyphenol oxidase,” explained Ms. Gavin.
She continued, “This enzyme is the culprit behind the undesirable browning of the fruit. Fortunately, there is a straightforward solution to prevent it!”
Application Instructions for Optimal Freshness
“After slicing your peaches, liberally coat them with lemon juice. The natural acidity of the lemon will help reduce the enzymatic reaction, keeping the peaches looking bright and fresh for an extended period,” Ms. Gavin advised.
Addressing Taste Concerns
Minimizing Citrus Flavor
The food expert also addressed a concern from a reader regarding a potentially “tart or sour” taste when using lemon juice on fruit.
“It will impart a slight citrus flavour,” she acknowledged. “To lessen the flavour intensity, submerge the peaches in a bowl of water mixed with lemon juice, and then drain and dry the fruit.”
Versatile Uses for Preserved Peaches
Properly stored with lemon juice, whether by squeezing on top, soaking, or even freezing, peaches can be used to create a variety of dishes, including:
- Fruit salads
- Pies
- Cobblers
- Or, they can be enjoyed as a refreshing snack on their own.
