Why are Strawberries Red?

Petite, plump and juicy … that’s the making of a perfect strawberry. Strawberries are one of the most popular fruits in North America, with over 70 varieties being grown. There is nothing quite like local fresh strawberries in season. Strawberries are available from June to July, on the edge between spring and summer. Looking for a fun activity and an excuse to enjoy some beautiful weather? Go strawberry picking!

Rich in nutritional benefits, strawberries offer a good amount of dietary fibre and potassium. What’s more, they actually offer more Vitamin C than any other berry! They are low in calories and make one of the best snack foods not only because of their nutritional value but also because how easy they are to transport and consume.

Generally, the first thing that draws us to pick one strawberry over another is its deep red ruby colour. Strawberries should also be firm, plump and well-shaped with fresh—looking green leafy caps. Give the strawberries a “sniff-test” to see if they have a nice sweet smell to them, that’s another factor to determine which strawberries to buy. Size is not a key determining factor when choosing strawberries. Always check your strawberries carefully before buying them. Examine the package from all angles, not just picking one up and taking it because the berries on top look good; you want to see if you can that none of the fruit hiding below the surface or at the bottom has gone bad. If you get home and find there are some mashed or bad berries discard them immediately.

Store your strawberries intact (with caps on), unwashed, in the refrigerator until you are ready to eat them. Rinse gently, drain, and remove the stems before you use them.

You can make use of your strawberries in so many simple and different ways: enjoy them as they are, cook with them, bake with them, make jam with them, add them to muffins, make yogurt parfaits and smoothies. They make a great addition to a spring-themed salad, to say nothing of all the strawberry deserts that are out there! One of my favourite uses has to be chocolate covered strawberries. The possibilities are endless!

So what does make a strawberry red? Strawberries contain a molecule called anthocyanidin which is the anthocyanin precursor. Anthocyanins are an important kind of antioxidant, and they are also responsible for giving red fruits their colour. Anthocyanidin however is colourless. When the anthocyadin reacts with a sugar molecule to become anthocyanin, the antioxidant, it becomes red. This explains why unripe strawberries are unsweet and colourless and the riper the strawberries the redder in colour it will be. The ripening process is key to the colour change. We infer that to find the best berries look for the deepest, darkest red berry to get optimum taste and nutrition.

Enjoy strawberry season!
