Scientistsresurrectthe taste ofmammothinlab-grownmeatball
科學家們在實驗室培育的肉丸中再現(xiàn)猛犸象的味道
【1】Amammothmeatballhas been created by acultivatedmeat company, resurrecting thefleshof the longextinctanimals. The project aims todemonstratethepotentialof meat grown from cells, without theslaughterof animals, and to highlight the link between large-scale livestock production and thedestructionof wildlife and the climate crisis.
一家人造肉公司制造出了一種猛犸象肉丸，再現(xiàn)這種早已滅絕的動物的肉。該項目旨在展示在不屠宰動物的前提下用細胞培養(yǎng)肉的可能性，并強調大規(guī)模牲畜生產與野生動物滅絕和氣候危機之間的聯(lián)系。
【2】Themeatballwas produced by Vow Food, an Australian firm, which is taking a different approach toculturedmeat. There are scores of companies working onreplacementsforconventionalmeat, such as chicken, pork and beef. But Vow isaimingto mix and match cells fromunconventionalspecies to create new kinds of meat. The firm has alreadyinvestigatedthepotentialof more than50species, includingalpaca,peacock,kangaroo, crocodile,buffaloand different types of fish. Their firstcultivatedmeat to be sold todinerswill be Japanesequail, which they expect will be in restaurants in Singapore this year.
這種肉丸是由澳大利亞細胞培養(yǎng)肉公司Vow Food生產的，該公司采用了一種不同的方法制造人造肉。目前有數(shù)十家公司正在研發(fā)雞肉、豬肉和牛肉等傳統(tǒng)肉類的替代品。但Vow Food的目標是混合和匹配非傳統(tǒng)物種的細胞，以創(chuàng)造新型肉類。該公司已經(jīng)調查了50多個物種的潛在潛力，包括羊駝、孔雀、袋鼠、鱷魚、水牛和各種魚類。他們第一批出售給食客的人造肉會是日本鵪鶉，預計今年將在新加坡的餐廳開始出售。
【3】“We have a behaviour-change problem when it comes to meatconsumption,” said George Peppou, the CEO of Vow Food. “The goal is totransitiona few billion meat-eaters away from eating [conventional] animalproteinto eating things that can be produced inelectrifiedsystems. And we believe the best way to do that is to invent meat. We look for cells that are easy to grow, really tasty andnutritious, and then mix and match those cells to create really tasty meat.”
Vow Food首席執(zhí)行官喬治·佩普（George Peppou）說:“我們在肉類消費方面存在行為改變的問題。我們的目標是讓數(shù)十億肉食者從食用[傳統(tǒng)的]動物蛋白轉變?yōu)槭秤每梢栽陔姎饣到y(tǒng)中生產的東西。我們相信最好的辦法就是造肉。我們尋找容易培養(yǎng)、真正美味且有營養(yǎng)的細胞，然后將這些細胞混合搭配，創(chuàng)造出真正美味的肉。”
【4】Tim Noakesmith, who co-founded Vow Food with Peppou, said: “We chose thewoollymammothbecause it’s asymbolofdiversityloss and asymbolof climate change.” Thecreatureis thought to have been driven toextinctionabout4,000years ago byhuntingand the warming of the world after the last ice age. Plant-basedalternativesto meat are now common butculturedmeat replicates the taste ofconventionalmeat.cultivatedmeat – chicken from Good Meat – iscurrentlysold only to consumers in Singapore, but two companies have now passed an approval process in the US. In2018, another company used DNA from anextinctanimal to creategummybears made from gelatine from amastodon, anotherelephant-like animal.
與佩普共同創(chuàng)立Vow Food的蒂姆·諾克史密斯（Tim Noakesmith）說:“我們選擇猛犸象是因為它是多樣性喪失和氣候變化的象征�！边@種生物被認為是在大約4000年前由于狩獵和最后一個冰河時代后全球變暖而滅絕的。以植物為基礎的肉類替代品現(xiàn)在很常見，但人造肉復刻了傳統(tǒng)肉類的味道。來自Good meat（美國新蛋白公司EatJust旗下培養(yǎng)肉品牌）的人造雞肉目前只賣給新加坡的消費者，但兩家公司現(xiàn)在已經(jīng)通過了美國的審批程序。2018年，另一家公司使用一種已滅絕動物DNA（脫氧核糖核酸），另一種類似大象的乳齒象的明膠制作了小熊軟糖。
【5】Vow Food worked with Prof Ernst Wolvetang, at the Australian Institute for Bioengineering at the University of Queensland, to create themammothmuscleprotein. His team took the DNA sequence formammothmyoglobin, a keymuscleproteinin giving meat itsflavour, andfilledin the few gaps usingelephantDNA. This sequence was placed in myoblaststemcells from a sheep, whichreplicatedto grow to the20bn cellssubsequentlyused by the company to grow themammothmeat. “It wasridiculouslyeasy and fast,” said Wolvetang. “We did this in a couple of weeks.” Initially, the idea was to produce dodo meat, he said, but the DNAsequencesneeded do not exist. No one has yet tasted themammothmeatball. “We haven’t seen thisproteinfor thousands of years,” said Wolvetang. “So we have no idea how our immune system wouldreactwhen we eat it. But if we did it again, we couldcertainlydo it in a way that would make it morepalatabletoregulatorybodies.”
Vow Food與昆士蘭大學澳大利亞生物工程研究所的厄恩斯特·沃爾夫唐（Ernst Wolvetang）教授合作，制造出猛犸象肌肉蛋白。他的團隊提取了猛犸象肌紅蛋白的DNA序列，這是賦予肉類風味的關鍵肌肉蛋白質，并用大象的DNA填補了少數(shù)序列空白。該序列被放入羊的成肌細胞干細胞中，這些細胞經(jīng)過復制，產生了200億個細胞，隨后該公司用這些細胞培育出猛犸象肉。沃爾夫唐說:“整個過程非常簡單和快速。我們只用了幾周時間就完成了。”他說，最初的想法是生產渡渡鳥肉，但所需的DNA序列并不存在。還沒有人嘗過猛犸肉丸。沃爾夫唐說:“我們已經(jīng)幾千年沒見過這種蛋白質了。所以我們不知道當我們吃它時，我們的免疫系統(tǒng)會如何反應。但如果我們再做一次，我們肯定會以一種更能讓監(jiān)管機構接受的方式來做。”
