日本科学家利用人粪制作肉食

It takes the saying waste not, want not, to a whole new level.

“勤俭节约，吃穿不缺”这句谚语如今被发展到了新的高度。

Flushed with success? Mitsuyuki Ikeda with his edible excrement concoction
A Japanese scientist has developed a 'meat' burger made out of human excrement（排泄物，粪便） .

Mitsuyuki Ikeda, a researcher from the Okayama Laboratory, came up with the novel approach after Tokyo Sewage asked him to come up with a way of using up the city's waste.

Mr Ikeda found that the poo which filled up the system was packed with protein because of all the bacteria.

His research team extracted the proteins to create an artificial steak, which is turned red with food colouring and flavoured with soy.

In a YouTube video posted recently he explained: 'We add reaction enhancer and put it in the exploder to produce the artificial meat.'

It is made up of 63 per cent protein, 25 per cent carbohydrates⁴（碳水化物） , three per cent lipids and nine per cent minerals.

But how has it gone down with the public? Well the team claims that in initial tests people reported it was delicious and tasted like beef.

And despite its unusual origins, the scientists argue that the new patties are far kinder to the environment as cattle create such a huge amount of greenhouse gas emissions⁵.

The 'meat' is currently 10 to 20 times more expensive than your average beef burger due to research costs, however Professor Ikeda hopes to bring costs down over time.

He added that the 'green' credentials⁶（证书，文凭） of the poo patty would help consumers to overcome any 'psychological barriers' they might have.
