Would You Eat a Broccoli Popsicle?

Uh-h-h-h, no. I don’t think I could convince anyone to eat a popsicle made of broccoli. But the question is: does freezing affect the nutrient content of broccoli? If it does, would it increase the nutrients like cutting it up does or lower the nutrient content compared to fresh?

That’s what researchers attempted to find out. They examined several varieties of broccoli that were frozen using an industrial freezing process, a method that’s much faster and colder than freezing vegetables at home. They found that some phytonutrients such as glucosinolates increased while total phenols remained constant in most broccoli cultivars. When they looked at carotenoids, there were higher levels in the industrial frozen broccoli when compared to fresh broccoli.

Why would freezing increase some of the phytonutrients? It may be that cells walls are damaged thus releasing the protective qualities of the phytonutrients. Whatever the reason, you can count on frozen broccoli to give you the phytonutrients we need from this vegetable.

In my research, I found different types of broccoli named Iron Man and Avenger. You want to have your kids eat more broccoli? Plant a garden next year with those catchily named broccoli cultivars and watch it disappear. No broccoli popsicle needed!

Saturday, what does cooking do to broccoli?

What are you prepared to do today?
