Here's an interesting article with a few theories:
Although this article has a different theory:
Picking tomatoes green and ripening them artificially is what makes them taste bad, according to Brett Clement, managing editor of Tomato Magazine. The longer a tomato stays on the vine, the higher its sugar levels and the better it tastes. But "tomatoes that are too ripe present difficulties for the food-service industry," Clement told us. "Slice into them and all the seeds and juice fall out."
According to Smith, what generates those "tomato-like pink things you find at the salad bar" is just the grower's choice of "cultivar"—the breed of tomato. Some cultivars that are picked green and treated with ethylene taste "absolutely wonderful," he insisted. But growers often choose cultivars based on soil and weather conditions, disease resistance, year-round availability, and profitability.
Next, we tried Samantha Winters, director of education and promotion for the Florida Tomato Committee. She said a tomato's taste has everything to do with handling. "Cold will absolutely kill the flavor," she noted. "A tomato produces a flavor enzyme as it ripens. As soon as the temperature goes below 55 degrees, the enzyme stops producing flavor—permanently." Nevertheless, tomatoes are often shipped with lettuce at its preferred temperature of 37 degrees.
We also spoke with Ed Beckman, president of the California Tomato Commission. Another problem, he said, is that people's tastes differ with locale, personal experience, and ethnicity. Southwesterners, for example, like acidic tomatoes, while people who grow their own tomatoes lean towards the sweeter varieties. Hispanics, meanwhile, tend to prefer pink, firm tomatoes.
Although this article has a different theory:
The mass-produced tomatoes we buy at the grocery store tend to taste more like cardboard than fruit. Now researchers have discovered one reason why: a genetic mutation, common in store-bought tomatoes, that reduces the amount of sugar and other tasty compounds in the fruit.
For the last 70-odd years, tomato breeders have been selecting for fruits that are uniform in color. Consumers prefer those tomatoes over ones with splotches, and the uniformity makes it easier for producers to know when it's time to harvest.
But the new study, published this week in Science, found that the mutation that leads to the uniform appearance of most store-bought tomatoes has an unintended consequence: It disrupts the production of a protein responsible for the fruit's production of sugar.
