問題詳情:
Which came first, the chicken or the egg? This question has remained unsolved for hundreds of years, yet soon it might not be a problem anymore — the egg of the future may not 41 a chicken at all.
But if not from a chicken, where will the egg come from? Apparently, a plant is one of the possibilities, as Hampton Creek, a food technology company in San Francisco, US, has found. They created a 42 for eggs, called Beyond Eggs, using a mixture of 11 plants, including sunflowers and a variety of beans.
Unlike the image you might now have in your mind, Beyond Eggs look nothing like 43 eggs. They are sold as gray powder that you mix with water before cooking. But the final product tastes just like the real thing.
But the question is, why 44 with “plant eggs”? What’s the problem with ordinary eggs?
The truth is that 99 percent of our eggs come from industrial warehouses (養雞場倉庫) where chickens are crowded into cages too small for them to even spread their wings. This cruelty is what 45 Hampton Creek to carry out the Beyond Eggs project in the first place.
In addition, the cages where chickens are kept so close together are a hotbed for viruses. To help the chickens stay healthy, farmers feed them antibiotics (抗生素), which may cause dangerous bacteria to grow 46 to the drugs and 47 spread to humans through eggs and meat.
In fact, 48 the egg is not a new idea, but Beyond Eggs seems to be the most successful attempt so far.
Besides their great taste and eco-friendliness, Beyond Eggs provide the same nutritional 49 as real eggs, and they’re even healthier since they don’t contain cholesterol (膽固醇). The company also 50 that the cost of their products is around 19 percent less than real eggs, which makes them more affordable.
