Preventing Mold on Berries

June2010 158

While researching a way to minimize mold on berries, I came across an article by Harold McGee which suggested doing something completely counterintuitive: Rinsing them in hot water for 30 seconds. He did research and found that swishing strawberries, raspberries, and blackberries in 125 degree water for 30 seconds significantly reduced the development of mold without reducing the quality of the fruit. He suggests 140 degree water for 30 seconds on blueberries which have thicker skin.

I have tried this on strawberries and found it to be effective. I used a candy thermometer to check the temperature of the water. I will have to wait until the rest of my berries ripen before I can do more experimenting.

Do you have any tips for reducing fruit spoilage?

    I have really good luck with the Debby Meyer Green Bags. I know many people say they have no luck at all with them, but I've had produce last far longer than I ever imagined by using them.

    They are plastic, but I personally don't have a problem with it since I am not cooking in them. Also I use them many, many times (until they have holes) before disposing of them, so they are not as expensive as they seem at first.

  2. Annie, My mom sent my some of the Debbie Meyer green bags. I am going to go put my peaches and nectarines in them right now. organic tree ripened fruit (read expensive) is turning faster than I would like!

  3. Neat idea.

    Our store had "manager's special" strawberries today, but they were already moldy. Um, no thanks. :)

  4. Hey. I like your new look! I have never heard that about the hot water though. I needed to know that last week lol.

    What a fantastic (and intriguing) tip! Thanks so much for sharing this. I'm tentatively going to try it, as like you said, it seems couterintuitive.

  7. Mrs. Green, I can't remember if you use F or C in GB. I didn't specify but the water temp. was 125degrees farenheit, so it would be about 51.6 degrees celcius.

  8. Can one use a meat thermometer to determine the water temp? I just bought raspberries and strawberries and want to do what I can to extend their freshness.

  9. I usually use a candy thermometer, but I would think that a meat thermometer would work. The nice thing about a candy thermometer is that it has a clip to kepp it in place on the bowl. Off to experiment…
