00:00:00is since the stone age. about
00:00:02400 years ago, growers began cross-breeding the
00:00:06biggest and sweetest varieties.
00:00:09now German breeders believe they've finally done it and
00:00:13created the perfect
00:00:14strawberry.com,
00:00:18wow, the world of food on this
00:00:21edition of DW's science show. welcome to
00:00:28tastes, and Tomorrow today. Stefan Krega
00:00:31dreams of breeding the perfect strawberry and earning
00:00:34sweet royalties from it. Wow,
00:00:37wow,
00:00:40incredible. This combination is
00:00:43wow. There's nothing else like it. This is a whole new
00:00:46league.
00:00:49The berries are so big, growers and pickers would love
00:00:52them, and consumers definitely would too,
00:00:55100%. This is a really, really good
00:00:58strawberry.
00:01:01but will this new cross ever reach supermarket shells?
00:01:05developing new variety can take up to 15 years and
00:01:08the road is full of
00:01:12the cold storage, which usually it's a pitfalls. at this horticultural research
00:01:15center, Simon is a bit like Heidi Clum, searching
00:01:19for the next top model of the strawberry world.
00:01:23he evaluates the most promising candidates from around the
00:01:26globe. are they resistant to disease and
00:01:31to propagate and how much fruit do they produce? right now,
00:01:34repeat fruiting varieties are in demand. here
00:01:38we have single crop varieties, they produce fruit once
00:01:41year, over there we have repeat fruiting or everbearing
00:01:45varieties. they flower and fruit throughout the growing season, so
00:01:49here they produce almost twice the yield, and because
00:01:52tabletop growing systems are
00:01:53expensive,
00:01:57lohnt sich das halt mehr damit zu arbeiten.
00:02:00when growers invest in high-tech production systems,
00:02:03they naturally expect a good return, but when it comes
00:02:06to flavor, repeat fruiting varieties still don't match the
00:02:10classic single crop strawberries,
00:02:13so can breeders combine the best of both worlds, high yields
00:02:17and great
00:02:18taste.
00:02:22that one had good flavor, but it could be a little firmer, so it's best for
00:02:26growers who sell directly to customers.
00:02:30After testing texture and flavor, Zemon also measures
00:02:37automobilion, Fridays on sweetness.
00:02:40Any new variety has to be better than what we're already growing. We
00:02:44know today's varieties inside
00:02:46out.
00:02:49Flavorless mass produced strawberries.
00:02:53Simon believes they'll become a thing of the
00:02:55past.
00:03:00Now for the final stop on the road to the perfect
00:03:02strawberry.
00:03:05Stefan Krega helped build this operation. Today he's
00:03:08back for visit. This is Europe's largest strawberry plant
00:03:12nursery. More than 100 million cold
00:03:15stored plants leave here every year, ready to be
00:03:19grown. We supply 3,500 customers
00:03:23in 26 countries. If you eat a strawberry in Germany,
00:03:26there's better than a 50/50 chance the plant came from beautiful.
00:03:32experts believe strawberries will increasingly be marketed by
00:03:36variety name, and for better flavor, customers may be
00:03:39willing to pay a
00:03:40and tastes, and little more. Stefan Krig's latest creation, the
00:03:43goddess variety is due to enter the mass market sometime
00:03:47soon. It's a repeat fruiting variety, but sweet and
00:03:50delicious.
00:04:30greenhouse gases on the planet, behind only the US
00:04:33and China. Research in Apples shows a
00:04:36simple way to interven.
00:04:39Once ripe, in Germany, the picked fruit is usually kept in cold
00:04:43rooms for up to 12
00:04:45less generational renewal in months, but once the apples are in there up to one and 10
00:04:47spoils. At peak season, that translates to up to
00:04:5140,00 metric tons of apples wasted, roughly the
00:04:54weight of the Titanic.
00:04:57One of the main reasons that number is so high is... Once they're in cold
00:05:01storage, it's really difficult to find out how the apples are
00:05:04doing. This is Tuwani Hoffman, a researcher at the
00:05:07Libnet's institute for agricultural engineering in Potstam.
00:05:11It's important to keep the... uh code room doors closed to
00:05:14maintain the conditions uniform inside, because if you
00:05:18constantly open the door so you would change all the environment, how the
00:05:21air flows, how the temperature is is
00:05:25distributed, so once they're in cold storage,
00:05:28you can hardly look at the apples, let alone see inside
00:05:31them, their condition has to be guessed at from factors like the
00:05:35temperature and humidity of the air inside the storage
00:05:38chamber, but it's really difficult to see how the fruit is getting on in
00:05:42cold rooms, an environment that's even a little bit too humid, for
00:05:46example, is not good news for the apples. the
00:05:49condensation process on the surface of the fruits,
00:05:53it can lead to the proliferation of
00:05:56fungy or bacterias or any microorganisms which are there,
00:05:59because imagine we already have the nutrients from the fruits and now
00:06:02we are also offering water, so we are just making a favorable
00:06:06condition for them to proliferate.
00:06:10that's where these sensors come in. "we are not only
00:06:13collecting data and logging it into the
00:06:16sensors, but we are also streaming in real time so we can see it
00:06:20uh in real time what is happening inside
00:06:24closed system.
00:06:26Currently operators generally would only see how many apples have
00:06:30spoiled at the end of the cold storage period,
00:06:33but in Potstam, twin of the fruit made from repurposed
00:06:37Christmas bobbles filled with hydrogel is helping
00:06:40researchers see what's going on. the synthetic
00:06:43apple mimics the health of the actual apples in cold storage and
00:06:46gathers information. sensors directly on the fruit measure
00:06:50condensation. this means the cold room conditions can be
00:06:54adjusted quickly after the reading is taken. now we also can
00:06:58get information directly from the the fruits within
00:07:01the bulk of fruits and this is really important because we
00:07:05know exactly what are the needs of these
00:07:07fruits? the sensors could be used to check the health
00:07:11of fruit kept at warm. temperatures as well, like melons or
00:07:14papayas. In Indonesia, food is often lost
00:07:18because of the way it's harvested, efforts to curve the loss are also
00:07:21hampered by lack of access to technology.
00:07:25Felicita Schneider is an international expert on the
00:07:28topic. In countries like Indonesia, I think
00:07:31technology can be major game changer.
00:07:34Um, especially AI supported technology can
00:07:37support the building of resilient and
00:07:41sustainable. food systems. I think the
00:07:44challenge for Indonesia is implement it a
00:07:48national scales, because technology is only as
00:07:51good as the users of the technology. One
00:07:55group of such users could be smallholder farmers. They
00:07:58dominate Indonesia's agricultural sector. Improving their
00:08:02access to technology could be a way to minimize the
00:08:05loss of crops after harvesting, for example. It's
00:08:09especially important with small holders to... to provide
00:08:13a good framework for the implementation of
00:08:16technology, so for example, you could provide
00:08:19trainings and awareness building campaigns
00:08:23within the small holders.
00:08:25researchers say interventions in the food chain are one of the most
00:08:29effective ways to help solve the problem. if technology
00:08:33like these sensors can be rolled out a national level, it could
00:08:37be major boost in the fight to reduce food waste
00:08:40worldwide.
00:09:02intense characteristic oder after consuming
00:09:05asparagus?
00:09:08Whether green or white, shoots from the asparagus are viewed as
00:09:11healthy edition. to any diet, but eating it can have
00:09:15noticeable side effect: soon after consumption, your urine can
00:09:19acquire a powerful loder, or at least
00:09:22in some people it can, lots of people would recognize the
00:09:25scent, though some can't smell it at
00:09:28all, confused yet?
00:09:31okay, let's start at the beginning.
00:09:34researchers believe that what ultimately leads to that smelly tinkle
00:09:38is a small molecule the plant contains lots of.
00:09:42Called asparagusic acid, it's pretty
00:09:45odorless, but see those two esses down at the
00:09:49bottom, those represent sulfur atoms and sulfur
00:09:52is an element that plays role in lots of powerful
00:09:55sense. It's a major component in skunk
00:09:59spray for instance, and it gives garlic its characteristic
00:10:03pong.
00:10:05After you chowel down on the vegetable, your body can turn
00:10:08innocuous asperagus acid into stuff that reaks.
00:10:12lot more, like dimethyl sulfide,
00:10:16one component in the smell of rotting meat, or
00:10:20methanethyol, which helps give some cheeses their
00:10:23distinctive tangy. smell, and not just
00:10:26cheeses.
00:10:29The molecule is also associated with bad
00:10:31breath. But not everyone's metabolism turns
00:10:35asparagus acid into lots of stronger smelling
00:10:38stuff. Some people don't have detectable asparagus
00:10:42pee. Why? Either their bodies don't break down
00:10:45asparagus acid in the first place, or don't turn it into
00:10:48noticeable levels of stinky compounds. What
00:10:52makes things even more complicated is the sense. of smell
00:10:55itself. Special cells inside your nose
00:10:59are studded with different kinds of highly specific
00:11:02receptors. When the right scent molecules dock on, you
00:11:06smell that specific smell. But if you
00:11:08don't have the genes to make receptors for the stinky compounds
00:11:12and asparagus pee, you won't smell them, even in your own
00:11:15urine. So bottom line, not everyone who
00:11:19eats asparagus will necessarily produce strongly
00:11:22scented characteristic pee after. and even in those who
00:11:25do, not everyone will be able to smell
00:11:28it.
00:11:31how can we feed a growing global population without pushing
00:11:35our planet to its limits?
00:11:38from rethinking livestock farming to reinventing how
00:11:42food is produced, the future may also include lab grown
00:11:45food.
00:11:49the global appetite for chocolate keeps flowing and growing, but the price
00:11:52of cocoa beans has been anything but sweet. Soring by up to 400
00:11:56perent in just two years. With
00:11:58alternatives urgently needed, a Swiss company is turning to Coco grown
00:12:02in bioreactors.
00:12:04Inside cells multiply and later become the raw material for chocolate
00:12:08made on the shores of Lake Zeric instead of in Ghana. The challenge
00:12:12for food brewer right now is that it isn't making money yet.
00:12:16Approval is a long and expensive
00:12:18process.
00:12:20Sticking it out with products that you can't yet sell is very difficult.
00:13:33Coco has spent seven years developing its machine, scanning stakes
00:13:37in a CT scanner to build the mathematical blueprint for
00:13:40recreating the cuts of meat. Now its
00:13:43first industrial system is ready. In seconds
00:13:46it can create rashes of bacon made from chicken meat and plant
00:13:49fat, and by the time it hits the pan, it looks like
00:13:53this:
00:14:00This product has 30% less CO2, 66%
00:14:04fewer calories, plus we can reach the 19% of the
00:14:08world's population who don't eat
00:14:10pork,
00:14:14bacon may not be everyone's favorite, but this version is
00:14:17surprisingly tasty, made from leftover meat pieces from the slaughter
00:14:21process and
00:14:24the same method. works with beef too,
00:14:27whether fish or meat, this approach ensures that slaughtered animals
00:14:31are used more efficiently.
00:14:34back in Switzerland, food brewer has already produced its first
00:14:38chocolate from lab grown coco, but does this
00:14:41spell competition for traditional cocoa
00:14:43farmers?
00:14:48we won't be displacing any jobs, because global demand for cocoa is
00:14:52so high that with this technology we'. There's
00:15:10agriculture now, farmers children no longer want to
00:15:14work in the fields, there are other opportunities.
00:15:17In this sense, we're looking for ways to attract these children who were
00:15:21born in the age of technology to work in this kind of agriculture.
00:15:33being turned into chocolate in the US within a year. In the
00:15:36EU. stricter approval rules mean it will take few months
00:15:40longer.
00:15:42Tropical rain forests are being cleared and burned to make way for oil palm
00:15:46plantations. Wildlife loses habitat,
00:15:49greenhouse gas emissions rise and pesticides harm both people and the
00:15:53environment. Palm oil may be everywhere, but producing it comes
00:15:57a heavy cost. Now
00:15:59scientists in Frankfurt are testing a different approach, producing
00:16:03key fatty acids industrially instead of using tropical crops.
00:17:37enzyme, the yeast becomes a tiny factory, inside
00:17:41bireactor, it produces the desired fatty acid in the
00:17:44form naturally found in palm
00:17:46oil.
00:17:49getting there took years of work, the team came up with
00:17:52ideas, tested them, refined them, and started
00:17:55again. thousands of experiments demanded scientific
00:17:59skill, imagination, and a great deal of patients.
00:18:03vier oder fünf zklen. die forschung ist
00:18:05inspiriert. take inspiration from what came
00:18:09before, test one idea after another, and then
00:18:12suddenly a small change unlock something
00:18:14big.
00:18:18the science has shown what's possible. the next challenge
00:18:21is scaling the process for large-scale production with the help of
00:18:25industrial
00:18:25partners.
00:18:29the interest from industry is already there. one company is
00:18:33expressed serious interest and contributed to parts of our work.
00:19:07palm plantations won't disappear anytime soon,
00:19:11this research brings us one step closer to a more sustainable
00:19:15future.
00:19:18when you hear soul food, you might think of comfort
00:19:21classics: mac and cheese, barbecue ribs
00:19:25or crispy fried chicken, but behind the name lies rich history
00:19:29that's often been reduced to stereotypes.
00:19:32there is absolutely no way in the world that
00:19:36black folks. only ate scrat how people are making decisions
00:19:40about what they're
00:19:41eating.
00:19:48lot of times when we think about the foods of especially black
00:19:51folks, we often point to oh, they're just eating sole food, and so their
00:19:55food decisions are essentially entangled in the past. according
00:19:59to the narrative, enslaved Africans in the Americas were
00:20:02only given scraps eat, the part of a pig that whites didn't
00:20:06want, called awful, ears
00:20:09snouts, tails and enerds. the story
00:20:12goes that the enslaved people often used hot spices and
00:20:16sugar to make these parts tastier or deep fried
00:20:19them. dishes like that still exist today, but they're
00:20:22generally viewed as bad for your health and belong to a
00:20:25cuisine colloquially referred to as soul food. we
00:20:29have eaten a variety of foods. so that
00:20:33whole scraps narrative is one that really captured.
00:20:37was sort of 1800s to
00:20:391865 at the end of enslavement,
00:20:43probably a traveller's account that saw black folks
00:20:47eating opal or the leftovers. or the
00:20:50entrails, but that absolutely is not the
00:20:54whole of African and African-American
00:20:56diet. Psychey Williams Forson wrote a
00:21:00book entitled eating while black. She's a professor of
00:21:04American studies at the University of Maryland. When you have
00:21:08people who repeat those narratives
00:21:11without knowing the history,
00:21:14you repeat the the
00:21:15stereotype.
00:21:19Another step. stereotype is that black people love eat
00:21:22watermelon and chicken. back in
00:21:252008 when Barack Obama was first elected US
00:21:29president, caricature circulated online of the
00:21:33White House with huge watermelon patch on the front
00:21:36lawn.
00:21:39there was nothing cute about it, it was absolutely racist
00:21:43be found in the post slavery
00:21:46era in the U.S. when some black people sold watermelon. earn
00:21:50money, slice resembles a wide smile, which is how black
00:21:54people were often portrayed,
00:21:56always grinning, always happy, always wonderfully
00:22:00delighted to be in servitude to white
00:22:03folks. we were accused of being watermelon eating
00:22:06darkies, chicken stealing darkies. that
00:22:10narrative goes all the way back to
00:22:13enslavement when we were often accused
00:22:16of um stealing.
00:22:20chickens, but stereotypes aside,
00:22:24another discussion is going on. statistics show
00:22:27that black people in the US are more likely to be
00:22:30overweight and they suffer from heart disease and diabetes more
00:22:34often than whites or latinos.
00:22:37an unhealthy diet is usually blamed, one rich in
00:22:41foods high and fat and sugar, like sou food
00:22:44or fast food.
00:22:47i think one of the things that motivated me, to do this
00:22:50research, um, was this, this conversation
00:22:54about health disparities, right? Sociologist
00:22:58Joseph wrote his dissertation on the black
00:23:01population in Jackson, Mississippi,
00:23:05and I wanted to know how black people up and down the
00:23:08socio-economic ladder make decisions about what they eat. I
00:23:12started with people who are homeless, I spent all my days with them, I
00:23:16ate what they ate, I only ate when they ate, and then after
00:23:19the... months through connections that I had made, I moved
00:23:22up to people are in poverty. Zinani um had two
00:23:26children at the time, has three children now. What I did was
00:23:30just spend time with Zanani and start to see what social
00:23:33structures is she experiencing.
00:23:37The term food deserts is often used to describe areas
00:23:40where there's not enough healthy food available, many
00:23:44times where socially disadvantaged people live,
00:23:47where supermarkets offering fresh produce. are far
00:23:50away,
00:23:53the scenario often goes hand in hand with an oversupply
00:23:57of cheap, unhealthy offerings from fast food
00:24:00restaurants,
00:24:03but does that description apply to where people like Xanani the single
00:24:06mother lived?
00:24:09if we look at Z9's food availability by just um drawing a circle
00:24:13around her address and seeing what kinds of grocery stores are available to her,
00:24:16I don't think we will capture as much, this...
00:24:20includes thinking about how she gets housing, it
00:24:23includes how she thinks about getting healthcare,
00:24:26transportation. i think for me food
00:24:29availability includes all those things and if we're able
00:24:32to think about her food,
00:24:36what's what what she has access to as being related to
00:24:39these other structures, i think it gives us lot more
00:24:42analytical.
00:24:45but back to the topic of soul food, which doesn't just include
00:24:49ingredients like: meat, fat and sugar, but often also
00:24:52plant-based components like sweet potatoes,
00:24:55beans, kale and ocra. foods popular
00:24:59among foodies today because they're considered
00:25:02healthy.
00:25:04it's a variety of foods that in combination would be
00:25:08most familiar to anyone who has southern groups. but also in
00:25:11African-American communities, we help to build
00:25:15the cuisine and the
00:25:17culinary
00:25:19legacy. the United States of America and
00:25:22globally, there's absolutely no way we survived offer
00:25:26merely scraps. Please don't
00:25:30reiterate the single
00:25:31story.
