Most drinks stating that they are fruit-flavored(水果味道的)contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.

“Shoppers need to check the labels(标签)before buying drinks, though sometimes the actual content can be non-existent,” said Food Commission spokesperson Lan Tokelove. “Food production is highly competitive.   小题1:   It will increase profits, and consumers won’t always realize they are being tricked.”

Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberry-flavored products sold in stores.  小题2: Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.

小题3:  Let’s take jam as an example. Some strawberry-flavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.

小题4: Consumers have the rights to know clearly about what they have bought. Under current UK law, Food packages do no not have to distinguish between natural and artificial flavoring. “Describing a product as strawberry flavor and covering the surface of the packed with pictures of strawberries is misleading.  小题5: Unfortunately, it is also legal and widespread,” Tokelove said.

A.The products which contain real fruit are popular with people.

B.Even products advertised as more natural often contained no fruit.

C.They found that about 60 percent of them didn’t contain any fruit at all.

D.If companies can cut their costs by using flavoring, they are likely to do so.E. It is important and necessary to demand a small amount of flavoring in the products.

F. Actually the product contains just a tiny percentage of strawberry or even no fruit at all.

G. The Food Commission suggested all flavors used in a product should be listed on the packaging.
