As the summer heat intensifies, many people are perplexed to find their freshly purchased vegetables and fruits from the supermarket wilted or overripe by the time they arrive home. However, according to agricultural experts, a simple change in habit can help keep your produce fresher for longer.

Storing groceries in the car trunk: A harmful habit during summer shopping

Professor Jeff Brecht, a renowned expert in the field of horticultural sciences at the Institute of Food and Agricultural Sciences (University of Florida), asserts: “The journey from the supermarket to your home is a critical step in food preservation, especially for fresh produce.”

High temperatures accelerate the natural ripening process of fruits and vegetables, making them more perishable. The car trunk can reach temperatures above 40 degrees Celsius within minutes, which is detrimental to heat-sensitive produce such as strawberries, grapes, peaches, leafy greens, and herbs.

A small change, a big difference: Relocating your groceries

Instead of leaving produce in the trunk, where it can be ‘cooked’ by the heat, Professor Brecht recommends placing groceries in the passenger seat or any other area of the car with air conditioning. “Let the vegetables and fruits sit beside you, benefiting from the cool airflow to maintain a stable temperature,” he emphasizes.

This simple tip can extend the shelf life of your groceries, keeping that box of strawberries fresh for a week instead of spoiling within hours.

A lesson in cold chain and cost savings

Food scientists emphasize the importance of maintaining a “cold chain” from the farm to your refrigerator to ensure food safety and freshness. A single break in this chain, such as leaving produce in a hot car, can compromise all preservation efforts.

So, during those scorching midday shopping trips, refrain from tossing your groceries into the trunk. By simply relocating your produce, you can enhance their freshness and longevity, ultimately saving yourself a significant amount of money.
