A New Study on Tomato Ripening & Flavor

A researcher out of Cornell University has released a study about the genes that control tomato ripening and flavor. There have been lots of studies done about what flavor chemicals or other factors affect tomato flavors. This article finds a correlation between the presence of the “uniform ripening gene” and lack of flavor.

Basically, tomatoes that contain the uniform ripening gene (it was originally a mutation in the 1920s) have lost the ability to photosynthesize in their fruit, reducing the amount of sugar and nutrients they develop in the fruit. The uniform ripening gene is what makes tomatoes turn uniformly red instead of having green shoulders or less uniform red color.

Read the whole article.

Now, that isn’t to say that all tomatoes with that uniform ripening gene are uniformly bad tasting. There is still lots of variation between the different varieties, and all those other studies about different flavor chemicals aren’t wrong either. It does lend some credence to the “heirlooms taste better” crowd, however. (Although, as I’ve said before, some heirlooms genuinely taste nasty! And not all hybrids necessarily have the uniform ripening gene!)
