Produce Refrigeration Basics
This weekend I bought a plethora of produce at the Farmers Market. Two days later a few items are already starting to get a little shriveled and whithery. I’ve made some accommodations – de-skinning and slicing the peaches for this weekend’s Blueberry Peach Pie and putting them in a ziplock bag in the freezer, and eating cherry tomatoes as morning snacks (which certainly isn’t a sacrifice).
I often wonder what should and shouldn’t be refrigerated to assist in maintaining longevity, and I decided it was time to sit down and do a little research. The most comprehensive listing I found is at Farm Fresh To You. I’ve listed some of the refrigeration basics from their site here for your quick reference but if you want more detailed lists I highly recommend the site.
The main cause of accelerated ripening and decay is ethylene gas. Some fruits and vegetables produce more than others. Some need to be refrigerated, some don’t. And some produce so much gas they shouldn’t be combined with other fruits and veggies. Any produce that should be isolated from other fruits and vegetables I’ve designated below with a *. The most important thing to remember is never refrigerate your tomatoes – they will lose all that great summer flavor! Leave them on the kitchen counter.
