1 . An American company has developed a new technique (技术) to make bread stay fresh for 60 days.
Scientists found that a kind of mould (霉菌) caused bread to go bad. The new technique kills the mould and keeps the food for longer time. This means there will be less waste of food in the world in future.
Food waste is a big problem in most developed countries. In the US, an average (普通的) family throws away 40% of the food they buy, which adds up to $165bn every year, about 330 million tons in weight. Bread takes a larger part. In the UK, 32% of the bread they buy is thrown away as waste when they can still be eaten.
The bread usually goes mouldy (发的) in around 10 days, but the American company says the new technique will keep the bread free from mould for two months.
”We treated a piece of bread in a special machine. At 60 days it had the same amount of mould as it was first made,“ says Mr. Stull, the leader of the company.
Although there are a lot of bread makers interested in the new technique, few customers like the idea. They say they don’t think a piece of bread which lasts for 60 days tastes good.
”We’ll have to make our customers accept the idea. But it will take some time,“ says Mr. Stull.
