Storing fruit for travel requires a balance of moisture control and protection from "ethylene gas," which speeds up spoilage. For sturdy fruits like apples and oranges, simply keeping them in a perforated plastic bag or a mesh pouch is sufficient to allow for airflow. Delicate fruits like berries should be washed, dried completely, and then stored in hard-sided airtight jars or containers to prevent them from being crushed in your bag. If you are traveling in a car, keeping fruit in a cooler is ideal, but avoid direct contact with ice, which can cause "cold burn" or mushiness. For long-haul flights, pre-slicing fruit like melons or mangoes and storing them in a sealed Tupperware container with a dry paper towel at the bottom can keep them fresh for hours. A pro tip is to store bananas and apples away from other produce, as they release high amounts of gas that can turn your other snacks brown prematurely. Always ensure your fruit is at "peak ripeness" before packing it for the journey.
