Purchasing fresh fruits and vegetables from your local farmers market or grocery store is a great way to ensure a healthy diet. But, do you ever wish you could keep those items fresh longer? Let’s look at some post-harvest storage tips to maintain a longer life for your fresh produce.
“Post-harvest” is defined as the handling of fresh produce from the point of harvest to when the product reaches the end user. Quality of fresh produce can never be regained after it is lost. Every fruit and vegetable has its own set of storage conditions that is temperature and moisture (humidity) dependent. With proper harvesting, pre-cooling and storage techniques, fresh produce can be stored to its maximum time. Following proven post-harvest techniques will slow softening (over-ripening), wilting, decay and odors.
The following chart, adapted from Storing Fresh Vegetables for Better Taste, lists appropriate storage temperatures for a variety of fruits and vegetables.
It is important to remember to refrigerate your fresh produce once it is cut or peeled for safety reasons. Produce should be stored in a moisture-resistant bag with air holes; this will prevent condensation, allow airflow and retain humidity. Remember to wash produce with clean running water before consuming, even when peeling. This will ensure that dirt from the outside does not transfer to the inside.
