Insekti na globalnoj agendi za hranu

Insekti na globalnoj agendi za hranu

Uzgojeni na farmama, istaknuti na jelovnicima, prerađeni u hranu ili korišteni kao hrana za životinje, insekti mogu biti važan izvor hrane.


Priprema hrane od muha (nije tako ružno)

Crni vojnički muhe se pare i polažu jaja unutar ovih kaveza na EnviroFlight -u.

U čudnom koledžanskom gradiću Yellow Springs, Ohio, koji je godinama dom mnogim nekonvencionalnim idejama, sada postoji mala tvornica insekata.

To je skromna operacija, generička kutijasta zgrada u malom industrijskom parku. Trebalo mi je vremena čak i da pronađem natpis sa imenom kompanije: EnviroFlight. Ali njegov cilj je sjajan: ljudi u EnviroFlight -u nadaju se da će njihovi insekti pomoći našoj planeti da uzgaja više hrane uz očuvanje zemlje i vode.

Ne očekuju da jedete insekte. (Naravno, Azijati i Afrikanci to rade, ali Amerikanci su izbirljivi.) Ideja je da će uzgojeni insekti postati hrana za ribe ili svinje.

Sve počinje u malom stakleniku. "Ovdje širimo našu vrstu", kaže Glen Courtright, osnivač EnviroFlight -a. "Ponekad ovo zovemo Ljubavna koliba."

Vidim nizove visokih kaveza u obliku cilindra. U njima lete ili sjede na mrežastim zidovima neki crni insekti koji pomalo liče na ose.

Ove muhe žive po cijelom američkom jugu, ali rijetko smetaju ljudima i ne šire bolesti. Odrasli su stidljiva stvorenja. Ne mogu ujesti. Ne mogu jesti (žive od uskladištene energije koju su izgradili kao larve). Sve što zaista rade je pariti se i snijeti jaja. To rade u ovim kavezima.

Jaja se pretvaraju u mladunce koji su toliko sitni da izgledaju poput prašine. Ali u rasadniku EnviroFlight -a uzgajaju masu iskrivljenih larvi. Kimberly Wildman drži ih u hrpama plastičnih ladica ili kanti.

"Kad bih ih nahranila, činilo bi se kao da se kanta praktično topila", kaže ona. "Odaju toliko topline."

Ličinke su nezasitne žderačice. Oni mogu konzumirati dvostruko veću težinu svaki dan, pretvarajući ih u proteine ​​i masti.

Glen Courtright, osnivač EnviroFlight -a, prikazan je na mašini koja sakuplja larve, odvajajući ih od otpadnih proizvoda.

Pojest će gotovo sve, što je ključ za Courtright -ov poslovni plan. Ove ličinke su neki od najvećih svjetskih prerađivača otpada. "Mi tjeramo stvari da nestanu!" On kaže.

Trenutno se većina larvi ovdje hrani otpadom iz postrojenja za proizvodnju etanola. Takođe rado jedu pivsko žito koje je ostalo od procesa proizvodnje piva.

Otpaci iz biljke pilećih grumenaca rade još bolje, kaže Courtright. Takve tvornice svake godine izbacuju milijune funti pilećih komadića, mrvica i uljanog mulja.

Ali moguće je pogledati ove larve i sanjati još veće. Na primjer, pomislite na klaonice. Amerikanci jedu samo 50 posto krave ili svinje. Ostatak životinja odlazi u industrijske kafilerije, koje taj otpad pretvaraju u različite proizvode, uključujući "prerađene životinjske bjelančevine" koje se hrane životinjama.

No, larve crnih vojničkih mušica također bi mogle potrošiti taj otpad, a da pri tome ne troše gotovo toliko energije kao toplane, kaže Courtright. Pokazuje mi novi eksperiment: oslobađa larve na komadićima piletine. "Bube troše ovaj materijal. Vjerovatno se potroši 90 posto materijala, a preostalo je samo malo kostiju, tetiva i krzna."

Bez obzira na to što jedu, larve insekata u ovoj zgradi debljaju - a zatim odlaze u komercijalnu peć.

Courtright otvara vrata pećnice i izvlači poslužavnik. "Dakle, ovdje imamo kuhane, dehidrirane larve insekata", kaže on. "Ima okus po slanom krekeru bez soli. Želite li ih okusiti?"

Prolazim. Courtright mu puni šaku u usta. "Nije loše!" kaže sa smiješkom.

Iskreno, Courtright nema ambicija prodavati užinu. Želi pretvoriti kuhane ličinke u stočnu hranu. Proteini su upravo ono što je potrebno mladim svinjama. Prizemne larve također bi mogle zamijeniti dio ribljeg brašna koje se trenutno koristi za ishranu uzgojenog lososa ili pastrve. Trenutno se taj obrok proizvodi od sardina, inćuna i menhadena koji se u ogromnim količinama vadi iz oceana. Ali taj izvor ribljeg brašna je ograničen.

Na način na koji Courtright to vidi, larve crnih vojničkih mušica mogle bi riješiti dva ogromna globalna problema odjednom: problem otpada i problem opskrbe hranom.

Zapravo, on nije prvi na to pomislio. Craig Sheppard, stručnjak za insekte sa Univerziteta Georgia, sada u penziji, već nekoliko decenija radi eksperimente sa crnim vojničkim mušicama.

Oslobodio je male ličinke na životinjskom gnoju - one ga lijepo čiste. Tokom godina, on i njegove kolege razgovarali su s nekim kompanijama o tome kako to pretvoriti u profitabilan posao.

Kuhane, dehidrirane larve muhe crnog vojnika mogu se preraditi u hranu za ribe ili svinje.

Bilo je trenutaka, kaže, kada se činilo da je ideja spremna za početak. "Momci [od potencijalnih investitora] bi došli ovamo i bili jako uzbuđeni. Pogledali bi našu produkciju, a mi bismo rekli kako bismo to mogli pojačati, a oni bi odšetali samo cereći se i pucajući. poput "Moramo to učiniti!" "A onda bi otišli kući i razgovarali s višim ljudima. I mogao sam samo zamisliti razgovor: 'Crvi? Zaista? ' I oni bi se povukli! "

Sheppard sumnja da se ideja činila malo previše čudnom. Mogli biste se nasmijati što ste to isprobali.

Ali sada postoji dosta projekata širom svijeta koji su se prihvatili ove ideje. Ljudi to pokušavaju u Južnoj Africi, Kanadi i Indoneziji.

Ono što se promijenilo je potražnja za stočnom hranom. Cijene ribljeg brašna su pale. Hrana za svinje je takođe skuplja. Širom svijeta postoji konkurencija za zemlju, usjeve i hranu.

Courtright očekuje da će konkurencija rasti. "Imamo deficit proteina. Imamo 7 milijardi ljudi na planeti, krenuli smo ka 9. Ne znamo kako ćemo ih hraniti", kaže on.

Pa će možda jednog dana tvornice mušica crnih vojnika prošarati krajolik.

Courtright razgovara s nekim velikim kompanijama, radeći na dogovorima za izgradnju prve. Možda ovaj put viši vrh neće reći: "Crvi? Zaista?"

Pogledali bi našu produkciju, a mi bismo rekli kako bismo to mogli pojačati, a oni bi odšetali samo cereći se i pucajući. poput "Moramo to učiniti!" "A onda bi otišli kući i razgovarali s višim ljudima. I mogao sam samo zamisliti razgovor: 'Crvi? Zaista? ' I oni bi se povukli! "

Sheppard sumnja da se ideja činila malo previše čudnom. Mogli biste se nasmijati što ste to isprobali.

Ali sada postoji dosta projekata širom svijeta koji su se prihvatili ove ideje. Ljudi to pokušavaju u Južnoj Africi, Kanadi i Indoneziji.

Ono što se promijenilo je potražnja za stočnom hranom. Cijene ribljeg brašna su pale. Hrana za svinje je takođe skuplja. Širom svijeta postoji konkurencija za zemlju, usjeve i hranu.

Courtright očekuje da će konkurencija rasti. "Imamo deficit proteina. Imamo 7 milijardi ljudi na planeti, krenuli smo ka 9. Ne znamo kako ćemo ih hraniti", kaže on.

Pa će možda jednog dana tvornice mušica crnih vojnika prošarati krajolik.

Courtright razgovara s nekim velikim kompanijama, radeći na dogovorima za izgradnju prve. Možda ovaj put viši vrh neće reći: "Crvi? Zaista?"


Priprema hrane od muha (nije tako ružno)

Crni vojnički muhe se pare i polažu jaja unutar ovih kaveza na EnviroFlight -u.

U čudnom malom koledžanskom gradiću Yellow Springs, Ohio, koji je godinama dom mnogim nekonvencionalnim idejama, sada postoji mala tvornica insekata.

To je skromna operacija, generička kutijasta zgrada u malom industrijskom parku. Trebalo mi je vremena čak i da pronađem natpis sa imenom kompanije: EnviroFlight. Ali njegov cilj je sjajan: ljudi u EnviroFlight -u nadaju se da će njihovi insekti pomoći našoj planeti da uzgaja više hrane uz očuvanje zemlje i vode.

Ne očekuju da jedete insekte. (Naravno, Azijati i Afrikanci to rade, ali Amerikanci su izbirljivi.) Ideja je da će uzgojeni insekti postati hrana za ribe ili svinje.

The Salt

Možda je vrijeme da zamijenite hamburgere za greške, kaže UN

Sve počinje u malom stakleniku. "Ovdje širimo našu vrstu", kaže Glen Courtright, osnivač EnviroFlight -a. "Ponekad ovo zovemo Ljubavna koliba."

The Salt

Ove slike bi vas mogle iskušati da jedete bube

Vidim nizove visokih kaveza u obliku cilindra. U njima lete ili sjede na mrežastim zidovima neki crni insekti koji pomalo liče na ose.

Ove muhe žive po cijelom američkom jugu, ali rijetko smetaju ljudima i ne šire bolesti. Odrasli su stidljiva stvorenja. Ne mogu ujesti. Ne mogu jesti (žive od uskladištene energije koju su izgradili kao larve). Sve što zaista rade je pariti se i snijeti jaja. To rade u ovim kavezima.

Jaja se pretvaraju u mladunce koji su toliko sitni da izgledaju poput prašine. Ali u rasadniku EnviroFlight -a uzgajaju masu iskrivljenih larvi. Kimberly Wildman drži ih u hrpama plastičnih ladica ili kanti.

"Kad bih ih nahranila, činilo bi se kao da se kanta praktično topila", kaže ona. "Odaju toliko topline."

Ličinke su nezasitne žderačice. Oni mogu konzumirati dvostruko veću težinu svaki dan, pretvarajući ih u proteine ​​i masti.

Glen Courtright, osnivač EnviroFlight -a, prikazan je na mašini koja sakuplja larve, odvajajući ih od otpadnih proizvoda.

Pojest će gotovo sve, što je ključ za Courtright -ov poslovni plan. Ove ličinke su neki od najvećih svjetskih prerađivača otpada. "Mi tjeramo stvari da nestanu!" On kaže.

Trenutno se većina larvi ovdje hrani otpadom iz postrojenja za proizvodnju etanola. Takođe rado jedu pivsko žito koje je ostalo od procesa proizvodnje piva.

Otpaci iz biljke pilećih grumenaca rade još bolje, kaže Courtright. Takve tvornice svake godine izbacuju milijune funti pilećih komadića, mrvica i uljanog mulja.

Ali moguće je pogledati ove larve i sanjati još veće. Na primjer, pomislite na klaonice. Amerikanci jedu samo 50 posto krave ili svinje. Ostatak životinja odlazi u industrijske kafilerije, koje taj otpad pretvaraju u različite proizvode, uključujući "prerađene životinjske bjelančevine" koje se hrane životinjama.

No, larve crnih vojničkih mušica također bi mogle potrošiti taj otpad, a da pri tome ne troše gotovo toliko energije kao toplane, kaže Courtright. Pokazuje mi novi eksperiment: oslobađa larve na komadićima piletine. "Bube troše ovaj materijal. Vjerovatno se potroši 90 posto materijala, a preostalo je samo malo kostiju, tetiva i krzna."

Bez obzira na to što jedu, larve insekata u ovoj zgradi debljaju - a zatim odlaze u komercijalnu peć.

Courtright otvara vrata pećnice i izvlači poslužavnik. "Dakle, ovdje imamo kuhane, dehidrirane larve insekata", kaže on. "Ima okus po slanom krekeru bez soli. Želite li ih okusiti?"

Prolazim. Courtright mu gomilu šake u usta. "Nije loše!" kaže sa smiješkom.

Iskreno, Courtright nema ambicija prodavati užinu. Želi pretvoriti kuhane ličinke u stočnu hranu. Proteini su upravo ono što je potrebno mladim svinjama. Prizemne larve također bi mogle zamijeniti dio ribljeg brašna koje se trenutno koristi za ishranu uzgojenog lososa ili pastrve. Trenutno se taj obrok proizvodi od sardina, inćuna i menhadena koji se u ogromnim količinama vadi iz oceana. Ali taj izvor ribljeg brašna je ograničen.

Na način na koji Courtright to vidi, larve crnih vojničkih mušica mogle bi riješiti dva ogromna globalna problema odjednom: problem otpada i problem opskrbe hranom.

Zapravo, on nije prvi na to pomislio. Craig Sheppard, stručnjak za insekte sa Univerziteta Georgia, sada u penziji, već nekoliko decenija radi eksperimente sa crnim vojničkim mušicama.

Oslobodio je male ličinke na životinjskom gnoju - one ga lijepo čiste. Tokom godina, on i njegove kolege razgovarali su s nekim kompanijama o tome kako to pretvoriti u profitabilan posao.

But there now are quite a few projects around the world that have picked up on this idea. People are trying it in South Africa, Canada and Indonesia.

What's changed is the demand for animal feed. Fish meal prices have gone through the roof. Feed for pigs is more expensive, too. Across the world, there's competition for land, crops and food.

Courtright expects that competition to grow. "We have a protein deficit. We have 7 billion people on the planet, heading for 9. We don't know how we'll feed them," he says.

So maybe, someday, black soldier fly factories will dot the landscape.

Courtright is talking to some big companies, working on deals to build the very first one. Maybe this time, the higher-ups won't say: "Maggots? Really?"


Making Food From Flies (It's Not That Icky)

Black soldier flies mate and lay eggs inside these cages at EnviroFlight.

In the quirky little college town of Yellow Springs, Ohio, home to many unconventional ideas over the years, there's now a small insect factory.

It's an unassuming operation, a generic boxy building in a small industrial park. It took me a while even to find a sign with the company's name: EnviroFlight. But its goal is grand: The people at EnviroFlight are hoping that their insects will help our planet grow more food while conserving land and water.

They don't expect you to eat insects. (Sure, Asians and Africans do it, but Americans are finicky.) The idea is, farmed insects will become food for fish or pigs.

It all starts in a small greenhouse. "This is where we propagate our species," says Glen Courtright, EnviroFlight's founder. "Sometimes we call this the Love Shack."

These Pictures Might Tempt You To Eat Bugs

I see rows of tall, cylinder-shaped cages. Flying around inside them, or sitting on the mesh walls, are some black insects that look a little like wasps.

These flies live all over the American South, but they rarely bother people, and they don't spread disease. The adults are shy creatures. They can't bite. They can't eat (they live off the stored energy that they built up as larvae). All they really do is mate and lay eggs. That's what they're doing in these cages.

The eggs turn into hatchlings that are so tiny they look like dust. But in EnviroFlight's nursery, they grow a mass of wriggling larvae. Kimberly Wildman keeps them in stacks of plastic trays or buckets.

"If I were to feed them, it would feel like the bucket was practically melting," she says. "They give off that much heat."

The larvae are insatiable eaters. They can consume twice their weight each day, turning it into protein and fat.

Glen Courtright, EnviroFlight's founder, is pictured with a machine that harvests the larvae, separating them from waste products.

They'll eat almost anything, which is the key to Courtright's business plan. These larvae are some of the world's great waste recyclers. "We make stuff go away!" he says.

Right now, most of the larvae here are feeding on waste from an ethanol plant. They're also happy to eat brewer's grain, which is left over from the beer-making process.

Scraps from a chicken nugget plant work even better, Courtright says. Such factories put out millions of pounds of chicken bits, breadcrumbs and oily sludge every year.

But it's possible to look at these larvae and dream even bigger. Think of slaughterhouses, for instance. Americans only eat 50 percent of a cow or a hog. The rest of the animal goes to industrial rendering plants, which turn that waste into a variety of products, including "processed animal protein" that's fed, in turn, to animals.

But black soldier fly larvae could consume that waste, too, without using nearly as much energy as rendering plants, Courtright says. He shows me a new experiment: He's turning the larvae loose on some leftover bits of chicken. "The bugs consume this material. Probably 90 percent of the material is consumed, and all that's left is a little bit of bone and sinew and fur."

No matter what they eat, the insect larvae in this building grow fat — and then they go into a commercial oven.

Courtright opens the door of the oven and pulls out a tray. "So what we have here is cooked, dehydrated, insect larvae," he says. "It kind of tastes like a savory cracker without salt. You want to taste them?"

I pass. Courtright pops a handful into his mouth. "Not bad!" he says with a grin.

Honestly, though, Courtright has no ambitions to sell snack food. He wants to turn cooked larvae into animal feed. The protein is just what young pigs need. Ground-up larvae also could replace some of the fish meal that's currently used to feed farmed salmon or trout. Right now, that meal is manufactured from sardines, anchovies and menhaden that are scooped from the ocean in massive quantities. But that source of fish meal is limited.

The way Courtright sees it, black soldier fly larvae could solve two enormous global problems at once: the waste problem and the food supply problem.

Actually, he's not the first to think of this. Craig Sheppard, an insect specialist at the University of Georgia, now retired, has been doing experiments with black soldier flies for a couple of decades now.

He's turned the little larvae loose on animal manure — they clean it up quite nicely. And over the years, he and his colleagues have talked to some companies about how to turn this into a profitable business.

Actually, he's not the first to think of this. Craig Sheppard, an insect specialist at the University of Georgia, now retired, has been doing experiments with black soldier flies for a couple of decades now.

He's turned the little larvae loose on animal manure — they clean it up quite nicely. And over the years, he and his colleagues have talked to some companies about how to turn this into a profitable business.

Cooked, dehydrated larvae of the black soldier fly can be processed into feed for fish or pigs.

There were times, he says, when the idea seemed ready to take off. "The guys [from potential investors] would come down here and get real excited. They'd look at our production, and we'd say how we could ramp it up, and they would be walking away just grinning and high-fiving, like 'We gotta do this!' " And then they'd go home and talk to the higher-ups. And I could just imagine the conversation: 'Maggots? Really?' And they'd back off!"

Sheppard suspects that the idea seemed just a little too weird. You could be laughed at for trying it.

But there now are quite a few projects around the world that have picked up on this idea. People are trying it in South Africa, Canada and Indonesia.

What's changed is the demand for animal feed. Fish meal prices have gone through the roof. Feed for pigs is more expensive, too. Across the world, there's competition for land, crops and food.

Courtright expects that competition to grow. "We have a protein deficit. We have 7 billion people on the planet, heading for 9. We don't know how we'll feed them," he says.

So maybe, someday, black soldier fly factories will dot the landscape.

Courtright is talking to some big companies, working on deals to build the very first one. Maybe this time, the higher-ups won't say: "Maggots? Really?"


Making Food From Flies (It's Not That Icky)

Black soldier flies mate and lay eggs inside these cages at EnviroFlight.

In the quirky little college town of Yellow Springs, Ohio, home to many unconventional ideas over the years, there's now a small insect factory.

It's an unassuming operation, a generic boxy building in a small industrial park. It took me a while even to find a sign with the company's name: EnviroFlight. But its goal is grand: The people at EnviroFlight are hoping that their insects will help our planet grow more food while conserving land and water.

They don't expect you to eat insects. (Sure, Asians and Africans do it, but Americans are finicky.) The idea is, farmed insects will become food for fish or pigs.

The Salt

Maybe It's Time To Swap Burgers For Bugs, Says U.N.

It all starts in a small greenhouse. "This is where we propagate our species," says Glen Courtright, EnviroFlight's founder. "Sometimes we call this the Love Shack."

The Salt

These Pictures Might Tempt You To Eat Bugs

I see rows of tall, cylinder-shaped cages. Flying around inside them, or sitting on the mesh walls, are some black insects that look a little like wasps.

These flies live all over the American South, but they rarely bother people, and they don't spread disease. The adults are shy creatures. They can't bite. They can't eat (they live off the stored energy that they built up as larvae). All they really do is mate and lay eggs. That's what they're doing in these cages.

The eggs turn into hatchlings that are so tiny they look like dust. But in EnviroFlight's nursery, they grow a mass of wriggling larvae. Kimberly Wildman keeps them in stacks of plastic trays or buckets.

"If I were to feed them, it would feel like the bucket was practically melting," she says. "They give off that much heat."

The larvae are insatiable eaters. They can consume twice their weight each day, turning it into protein and fat.

Glen Courtright, EnviroFlight's founder, is pictured with a machine that harvests the larvae, separating them from waste products.

They'll eat almost anything, which is the key to Courtright's business plan. These larvae are some of the world's great waste recyclers. "We make stuff go away!" he says.

Right now, most of the larvae here are feeding on waste from an ethanol plant. They're also happy to eat brewer's grain, which is left over from the beer-making process.

Scraps from a chicken nugget plant work even better, Courtright says. Such factories put out millions of pounds of chicken bits, breadcrumbs and oily sludge every year.

But it's possible to look at these larvae and dream even bigger. Think of slaughterhouses, for instance. Americans only eat 50 percent of a cow or a hog. The rest of the animal goes to industrial rendering plants, which turn that waste into a variety of products, including "processed animal protein" that's fed, in turn, to animals.

But black soldier fly larvae could consume that waste, too, without using nearly as much energy as rendering plants, Courtright says. He shows me a new experiment: He's turning the larvae loose on some leftover bits of chicken. "The bugs consume this material. Probably 90 percent of the material is consumed, and all that's left is a little bit of bone and sinew and fur."

No matter what they eat, the insect larvae in this building grow fat — and then they go into a commercial oven.

Courtright opens the door of the oven and pulls out a tray. "So what we have here is cooked, dehydrated, insect larvae," he says. "It kind of tastes like a savory cracker without salt. You want to taste them?"

I pass. Courtright pops a handful into his mouth. "Not bad!" he says with a grin.

Honestly, though, Courtright has no ambitions to sell snack food. He wants to turn cooked larvae into animal feed. The protein is just what young pigs need. Ground-up larvae also could replace some of the fish meal that's currently used to feed farmed salmon or trout. Right now, that meal is manufactured from sardines, anchovies and menhaden that are scooped from the ocean in massive quantities. But that source of fish meal is limited.

The way Courtright sees it, black soldier fly larvae could solve two enormous global problems at once: the waste problem and the food supply problem.
