Food ‘made from air’ could compete with soya 用空氣做成的食物價格可與大豆價格競爭

225

芬蘭科學家稱,在未來十年內,這種「用空氣製成的」蛋白質將在價格上與大豆競爭。這種蛋白質是由土壤細菌製成的,這種細菌以電解水中的氫為食。

With farming blamed for contributing to many environmental problems, there’s been increasing investment in novel foods grown from bacteria. A study last year concluded that protein from microbes was several times more efficient than soya in terms of land use and required just a tenth of the water.

由於務農活動被認為是造成許多環境問題的原因,人們對由細菌製成的新型食物的投資不斷增加。去年的一項研究得出結論:製造微生物蛋白質的土地使用效率要比種植大豆高出數倍,而且用水量僅需其十分之一。

The bacteria food, Solein, can be used as a substitute for soya in a host of foods, such as pies, ice creams, breads and cakes. It can also feed livestock without harming rainforests in the way new soya plantations often do.

這個名為 「Solein」 的細菌食品可作為許多食物中大豆的替代品,如餡餅、冰淇淋、面包和蛋糕。它還可以在不破壞熱帶雨林的情況下用來喂養牲畜,在這一點上它與多數新型大豆種植園的做法相同。

Academics say it won’t be a cure for all the problems associated with farming, but it will help if people are willing to eat it.

學者們表示,這不會完全解決與務農相關的所有問題,但如果人們願意吃它,則將有一些幫助。

閱讀理解:請在讀完上文後,回答下列問題。

1. How is growing protein from microbes more efficient than growing soya?

2. Why has there been increasing investment in foods grown from bacteria?

3. How much damage is there to the rainforest when livestock are fed bacteria-grown foods?

4. True or false? Soleine can be eaten as a substitute for things like ice cream and cakes.

答案

1. How is growing protein from microbes more efficient than growing soya?
Growing protein from microbes was several times more efficient than soya in terms of land use and required just a tenth of the water.

2. Why has there been increasing investment in foods grown from bacteria?
Farming has been blamed for contributing to many environmental problems. As a result, there’s been increasing investment in novel foods grown from bacteria.

3. How much damage is there to the rainforest when livestock are fed bacteria-grown foods?
According to the report, none: Bacteria food can feed livestock without harming rainforests in the way new soya plantations often do.

4. True or false? Soleine can be eaten as a substitute for things like ice cream and cakes.
False. The bacteria food, Soleine, can be used as a substitute for soya in a host of foods, such as pies, ice creams, breads and cakes.
