1 00:00:01,920 --> 00:00:06,520 Speaker 1: Welcome to brain Stuff production of I Heart Radio. Hey 2 00:00:06,559 --> 00:00:10,600 Speaker 1: brain Stuff Lauren bog Obam Here. Fresh tomatoes pile high 3 00:00:10,600 --> 00:00:13,200 Speaker 1: and grocery store produce sections twelve months out of the year, 4 00:00:13,840 --> 00:00:17,160 Speaker 1: but for tomato aficionados they're only good for a short season, 5 00:00:17,600 --> 00:00:21,040 Speaker 1: or maybe not ever. Grocery store tomatoes have long had 6 00:00:21,040 --> 00:00:26,320 Speaker 1: a reputation for being bland, meally, too firm, tasteless, and dry. 7 00:00:27,000 --> 00:00:30,080 Speaker 1: There are scientists working to save grocery store tomatoes, and 8 00:00:30,280 --> 00:00:32,720 Speaker 1: not just by encouraging people to garden or shop at 9 00:00:32,720 --> 00:00:36,760 Speaker 1: farmers markets. Through science and honestly good grocery store tomato 10 00:00:36,880 --> 00:00:40,159 Speaker 1: maybe on the market within five years. We spoke with 11 00:00:40,200 --> 00:00:43,920 Speaker 1: Harry Clee, professor of horticultural science at the University of Florida, 12 00:00:44,120 --> 00:00:46,600 Speaker 1: who's putting his passion for tomatoes into the long work 13 00:00:46,640 --> 00:00:49,920 Speaker 1: of developing a better tomato for the mass market. He said, 14 00:00:50,240 --> 00:00:52,800 Speaker 1: we're not going to consider our program of success until 15 00:00:52,840 --> 00:00:57,200 Speaker 1: all grocery store tomatoes taste good. According to Clee, the 16 00:00:57,280 --> 00:01:00,160 Speaker 1: number one complaint about produce in America is the favor 17 00:01:00,200 --> 00:01:02,920 Speaker 1: of grocery store tomatoes. It's a problem that's been around 18 00:01:02,920 --> 00:01:06,160 Speaker 1: for decades. Clever members in n seven essay in the 19 00:01:06,160 --> 00:01:08,800 Speaker 1: New Yorker about how hard it is to find truly ripe, 20 00:01:08,840 --> 00:01:14,039 Speaker 1: fresh tomatoes. So how did tomatoes end up tasting so blah? 21 00:01:14,240 --> 00:01:18,360 Speaker 1: The problem lies in the entire market chain. Clip points out. 22 00:01:18,720 --> 00:01:21,600 Speaker 1: Farmers aren't paid on flavor. They're paid on pounds of 23 00:01:21,600 --> 00:01:24,200 Speaker 1: tomatoes they put in a box. Growers will tell you 24 00:01:24,240 --> 00:01:28,920 Speaker 1: they can't control flavor. What the market values motivates growers 25 00:01:28,920 --> 00:01:32,440 Speaker 1: to prioritize fast growth, high yields, disease resistance, and a 26 00:01:32,520 --> 00:01:36,080 Speaker 1: long shelf life. Breeders have been developing tomatoes in response 27 00:01:36,120 --> 00:01:39,240 Speaker 1: to those qualities that growers are looking for. Tomatoes don't 28 00:01:39,280 --> 00:01:41,080 Speaker 1: have to taste good for any of that to happen. 29 00:01:42,280 --> 00:01:44,920 Speaker 1: Cli pointed out that the loss of flavor isn't intentional 30 00:01:45,000 --> 00:01:47,120 Speaker 1: on anyone's part. It's just a side effect of the 31 00:01:47,160 --> 00:01:50,760 Speaker 1: neglect of attention to flavor. He compares it to a symphony. 32 00:01:50,920 --> 00:01:53,880 Speaker 1: If one instrument is missing, you probably wouldn't notice. If 33 00:01:53,920 --> 00:01:57,040 Speaker 1: two or three instruments bow out, and experienced musician might notice. 34 00:01:57,680 --> 00:02:00,880 Speaker 1: But if one by one instruments leave the orchestra, eventually 35 00:02:00,920 --> 00:02:03,800 Speaker 1: you'll notice something's missing. And in the case of fruit 36 00:02:03,840 --> 00:02:07,960 Speaker 1: like tomatoes, well, in Klee's words, flavor over fifty years 37 00:02:08,120 --> 00:02:11,280 Speaker 1: has gone to hell. The growers who do get paid 38 00:02:11,320 --> 00:02:13,960 Speaker 1: on flavor focus on local sales to customers who live 39 00:02:14,000 --> 00:02:17,720 Speaker 1: nearby and provide repeat business both home cooks and restaurants. 40 00:02:18,200 --> 00:02:20,240 Speaker 1: Those are the growers who can pick tomatoes once they've 41 00:02:20,320 --> 00:02:22,280 Speaker 1: ripened on the vine, and they don't have to ship 42 00:02:22,320 --> 00:02:26,160 Speaker 1: them far and risk damage. We also spoke with Julie Dawson, 43 00:02:26,240 --> 00:02:28,880 Speaker 1: a faculty member at the University of Wisconsin Madison, who 44 00:02:28,919 --> 00:02:31,720 Speaker 1: does tomato variety trials, including varieties from a number of 45 00:02:31,760 --> 00:02:35,360 Speaker 1: different public and private sector breeders. Some varieties of the 46 00:02:35,360 --> 00:02:39,000 Speaker 1: trials come from Seed Savers Exchange, an organization that's devoted 47 00:02:39,000 --> 00:02:42,880 Speaker 1: to preserving America's diversity and food and garden plants by collecting, sharing, 48 00:02:42,919 --> 00:02:46,720 Speaker 1: and saving seeds and by encouraging people to grow them. 49 00:02:46,880 --> 00:02:50,120 Speaker 1: She said, we hope our trials help breeders develop varieties 50 00:02:50,120 --> 00:02:52,240 Speaker 1: that have the flavor that make people want to buy 51 00:02:52,280 --> 00:02:56,280 Speaker 1: and eat more. She explained that flavor can get bread 52 00:02:56,280 --> 00:02:59,839 Speaker 1: out in any number of unexpected ways. For example, there's 53 00:02:59,840 --> 00:03:02,280 Speaker 1: a gene that producers want because it makes tomatoes ripen 54 00:03:02,400 --> 00:03:05,240 Speaker 1: uniformly across the whole fruit all at once, but it 55 00:03:05,320 --> 00:03:08,880 Speaker 1: also changes the way sugars accumulate in the fruit, but 56 00:03:09,000 --> 00:03:11,440 Speaker 1: she also said the bigger part of why they don't 57 00:03:11,480 --> 00:03:13,799 Speaker 1: taste good is due to how people manage them, such 58 00:03:13,840 --> 00:03:16,240 Speaker 1: as picking them green. A lot of the ripening on 59 00:03:16,280 --> 00:03:19,040 Speaker 1: the plant creates sugars and volatile compounds that make the 60 00:03:19,040 --> 00:03:22,200 Speaker 1: tomatoes taste good. They're easier to ship when they're under ripe, 61 00:03:22,240 --> 00:03:25,400 Speaker 1: but they will never develop all of those flavors, and 62 00:03:25,600 --> 00:03:28,720 Speaker 1: ripening tomatoes commercially with ethylene gas is no substitute for 63 00:03:28,760 --> 00:03:31,680 Speaker 1: the work nature does on the vine. Dawson said, it 64 00:03:31,800 --> 00:03:34,480 Speaker 1: just turns them red. You don't get all the volatiles 65 00:03:34,480 --> 00:03:37,040 Speaker 1: and secondary compounds that make it smell like a tomato 66 00:03:37,160 --> 00:03:42,200 Speaker 1: and taste good. So now clear and numerous horticultural scientists 67 00:03:42,200 --> 00:03:45,960 Speaker 1: are working to bring flavor back, but growers and supermarkets 68 00:03:46,120 --> 00:03:49,440 Speaker 1: still need the qualities of a modern tomato. Klie said 69 00:03:49,760 --> 00:03:52,240 Speaker 1: breeding is now a balancing act because growers still want 70 00:03:52,240 --> 00:03:54,760 Speaker 1: a good yield and disease resistance. We have to keep 71 00:03:54,840 --> 00:03:58,600 Speaker 1: key pieces in. At the University of Florida, the Horticultural 72 00:03:58,600 --> 00:04:01,360 Speaker 1: Science Department is growing over a hundred varieties of tomatoes 73 00:04:01,560 --> 00:04:03,680 Speaker 1: and uses a tasting panel of over a hundred people 74 00:04:03,720 --> 00:04:06,640 Speaker 1: to help identify what makes it tomato taste good. They've 75 00:04:06,640 --> 00:04:08,840 Speaker 1: come up with a list of compounds that impact flavor. 76 00:04:09,080 --> 00:04:11,760 Speaker 1: The tasting panel helps them identify what people like, and 77 00:04:11,800 --> 00:04:13,960 Speaker 1: then they determine how much of each compound is in 78 00:04:13,960 --> 00:04:17,039 Speaker 1: the tomatoes that get approval from the panel. The process 79 00:04:17,080 --> 00:04:20,800 Speaker 1: produces a scientific recipe for a great tomato. Klie said, 80 00:04:21,240 --> 00:04:24,400 Speaker 1: DNA sequencing has become cheap, so if sequenced the genomes 81 00:04:24,400 --> 00:04:27,400 Speaker 1: of five hundred different varieties of tomatoes, they can identify 82 00:04:27,480 --> 00:04:30,480 Speaker 1: jeans that make good tasting modern tomatoes, trace where those 83 00:04:30,560 --> 00:04:33,080 Speaker 1: genes came from, and bring them back. It creates a 84 00:04:33,120 --> 00:04:37,240 Speaker 1: breeding roadmap. Right now, Clean his team are working on 85 00:04:37,320 --> 00:04:40,520 Speaker 1: nine different genes to put into modern tomatoes, creating fruit 86 00:04:40,560 --> 00:04:43,240 Speaker 1: with the yield, disease resistance, and shelf life that growers 87 00:04:43,240 --> 00:04:45,960 Speaker 1: and markets want, but the flavor the tomato lovers crave. 88 00:04:47,240 --> 00:04:49,760 Speaker 1: But the challenge with creating better fruit and vegetables is 89 00:04:49,800 --> 00:04:52,800 Speaker 1: that it takes time. In Florida, Clean his team can 90 00:04:52,800 --> 00:04:55,920 Speaker 1: only grow two generations of tomatoes a year, but better 91 00:04:55,960 --> 00:04:59,320 Speaker 1: tomatoes are on the horizon. Kali says tasting panels in 92 00:04:59,360 --> 00:05:01,839 Speaker 1: summer of twenty nineteen will help them finalize a tomato 93 00:05:01,960 --> 00:05:04,560 Speaker 1: that's got it all. Once that's done, the challenge is 94 00:05:04,600 --> 00:05:07,200 Speaker 1: getting growers to take a chance on planting and selling them, 95 00:05:07,240 --> 00:05:10,719 Speaker 1: and growers tend to adopt new plants conservatively, but the 96 00:05:10,800 --> 00:05:13,479 Speaker 1: university is working with several commercial seed companies that want 97 00:05:13,480 --> 00:05:15,520 Speaker 1: to be the first in the market with good tomatoes. 98 00:05:16,520 --> 00:05:18,679 Speaker 1: Consumers have a role to play and getting better tomatoes 99 00:05:18,720 --> 00:05:22,560 Speaker 1: to market to buy them, Kali said. Some people are 100 00:05:22,560 --> 00:05:25,000 Speaker 1: willing to pay more for great flavor, but most people 101 00:05:25,000 --> 00:05:27,440 Speaker 1: are price sensitive. If you pay little, you get what 102 00:05:27,480 --> 00:05:29,640 Speaker 1: you pay for. People need to step up and pay 103 00:05:29,680 --> 00:05:33,039 Speaker 1: for better tomatoes. If you've got a garden plot and 104 00:05:33,040 --> 00:05:34,760 Speaker 1: you can't wait for some of the tomatoes developed at 105 00:05:34,760 --> 00:05:37,039 Speaker 1: the University of Florida, you can get seeds that aren't 106 00:05:37,040 --> 00:05:39,480 Speaker 1: on the market yet. You can donate ten dollars towards 107 00:05:39,520 --> 00:05:42,479 Speaker 1: cles Genetic Tomato Research to receive packets of three varieties. 108 00:05:42,800 --> 00:05:45,920 Speaker 1: Search online for the Clear Garden gem web page. That's 109 00:05:46,040 --> 00:05:48,720 Speaker 1: k l e E. If you grow them, they would 110 00:05:48,720 --> 00:05:56,000 Speaker 1: love to hear how they perform in your garden.
