Xinhua
has a report about artificial eggs that were apparently sold by a
street vendor in Handan, Hebei Province. The report says that the man
who took the eggs home found that the eggs' yolk and white were all
mixed up, and di not have any flavor. After inspection by "relevant
departments" it was found that the dodgy eggs' shells were made from
calcium carbonate while the fake yolks were made from a mixture of
gelatine, starch and other chemicals.
