How Tomatoes Lost Their Taste

(we already knew taste had been bred out, this explains it in detail)

snip

In most tomatoes on supermarket shelves, however, SlGLK2 is inactive. "We looked at about a dozen varieties, one from Asia, some from Europe, and all of them had the same mutation," says Powell. The researchers do not know where the mutation—a string of bases consisting of seven As, where there should only be six—came from initially. But it might have arisen independently multiple times, says Powell, because repetitions of the same letter of the genetic alphabet are prone to errors.

Francis is not yet convinced that that will improve the taste, however. The increased sugar content might also be due to changes in other parts of the plants, he suggests. (About 80% of the sugar in tomatoes is actually produced in the leaves and transported to the fruit later.) He also cautions that the results obtained in small greenhouse pots might be different from what growers would see in field-grown tomatoes. "The real culprit affecting tomato flavor is a production system that picks tomatoes before they are ripe," because that changes the ripening process, he says, interrupting for instance the conversion of starch to sugar.

hubby was reading that to me. i have had my concerns for years now. i do not trust, our food supply. being the shopper and cook exclusively, i see too many changes.

the other day i was looking for the oranges. i had glasses on for distance, so could see in front as well. i told produce dude, where are the oranges? they were right in front of me. mostly green. i told him... oranges = orange.

bananas are another that just do not feel, look, act like a banana anymore. that makes me wonder

pears are sold crispy like apples.

i am having a tough time finding good onions and potatoes anymore and that use to be a given.

Found a local market about a month ago which sold locally grown strawberries and they TASTED like strawberries. Won't buy supermarket strawberries again; they look pretty, and taste like nothing. Was sad after the local strawberry season ended.

better than their pesticide laden counter-parts as well. So are apples and oranges, generally speaking.

That and the asparagus just blew us away. We had so much asparagus that we actually GAVE AWAY gallon bags of it!!! It isn't even a large plot - it just kept producing. Now it's moving into "fairy forest" territory, but we're still getting enough shoots to keep us happy.

Our favorite variety are the blue ones, but I couldn't get them this year so we went with a Yukon sort of thing. You get back the cost of the seed potatoes many times over.

but it's just too dry and hot around here. Even with watering I don't know how they'd do. My garden, even with watering, is scorched.

I guess I'll have to hope for next year.

not even the hybrids. Of course, I grow my tomatoes for flavor not shipping.

The loss of lycopene isn't good. In the U.S. we tend to get most of our lycopene from tomato products or cooked tomatoes.

Lycopene reduction isn't the only nutritional loss from tomato breeding. Some wild tomatoes contain another antioxidant, anthocyanin. It's virtually absent from our tomato varieties although present in the inedible parts of the plant. There's a new tomato in seed catalogs called "Indigo Rose" and it's an OP variety bred from a cross between a wild Chilean variety and a modern type.

I've grown the blue tomato - it isn't very good. I am not convinced about the quality/stability of the offspring either (there is a big thread about these blue types on the Tomatoville website).

There are so many good reasons to grow the older varieties - flavor, visual interest, history, ability to save the seeds (and the stories). I suspect better nutritional content is there as well.

The attempts to x-breed these started in the 1960s and Indigo is being touted by two seed catalogs that I trust -- Territorial and Johnnys. I haven't tasted one yet so I can't say whether it's worth a repeat. I should have ripe ones by mid-July.

Let me know what you think of the flavor. I am too deep in leading the Dwarf tomato breeding project to want to fit any more tangential stuff in!

are just delicious. They taste like the tomatoes of my childhood. So, the premature picking is a big problem. And that is true for most fruits and vegetables -- except, for example, avocados that have to sit in a dish (preferably with some ripe bananas) before they are ready to eat.

All of the genes in the world aren't going to make it taste good if you pick it green, gas it, ship it 2000 miles, hold it in cold storage for God knows how long, coat it with wax, and otherwise basically embalm it.

OTOH, I've never had any vine-ripened tomato, with or without green shoulders, that was as bad as a typical grocery store trainwreck. Any of them can be decent, its just that some are better than other.

17. Not all vine ripen tomatoes are tasty.

We got our greenhouse up this year and grew some tomatoes in it. We used soil from the back of our property where a stream use to be to fill the greenhouse because the ground was solid shale. We are Certified Naturally Grown so we don't use petroleum pesticides and fertilizers either in the greenhouse or outside. I must say the tomatoes (but not all the produce in the greenhouse) lack a certain flavor. I don't know what about the greenhouse makes them taste bland but my outside tomatoes have a more complex and rich flavor. Maybe it's all the bugs they are fighting off outside or the slightly cooler temperatures outside at night. But the greenhouse tomatoes sure look very pretty and they sell better than the more flavorful outside tomatoes.

I tend to let them over ripen on the vines...certain ones have some great flavor.

When we were growing up we had to basket pick tomatoes in a specfic prescribed manner on the family farm. Slightly greens went to the bottom and the ripest to the top. They were all wiped and then the baskets were covered with towels or cloths and left in a shady area out side. We never had a problem selling them they were in high demmand. My uncle learned it from his father and grandfather they came from the old county. Hybrids tend to produce more meat but they do lack a bit in flavor and thats what most growers use.

In about 3 weeks I'll be able to taste my Rutgers tomatoes - old variety but still the best! I also grow Golden Yellow, Mister Stripey, Big Boy, and Sun-Sugar (orange and delicious).
