Kentucky Fried Chicken, the US fast food giant has again sparked food safety
concerns around China, with its outlets
being accused of repeatedly using same frying oil for as many as
10 days, which experts believe may cause cancer.
The Guangzhou-based Information Times reports that KFC branches in some
cities in northwest Shaanxi Province have been discovered putting Magnesium Trisilicate into frying oil to prolong
its usage. Magnesium Trisilicate is a white, odorless and tasteless powder,
which can decolorize and absorb the odor and some impurities of the overused
turbid oil, as well as reducing its
acidity and oxidization. After being "polished," the cooking oil is used over
and over again for up to 10 days by some KFC outlets in Xianyang city, Shaanxi
However, the KFC Corp (China) claimed on Thursday that the overused oil is
concern-free as it is in compliance with the national food safety standard. It
argues that the "oil purifier" is approved by the US Food and Drug
Administration as a safe aide substance. Experts with the World Health
Organization and Food and Agriculture Organization of the United Nation all
agree that the powder purifier can be used as food
additive. KFC Corp (China) argues it will stop using it the time
it is found to breach China's food safety standard.
Despite KFC's defense, food experts have not yet being convinced as they
believe that even if their additive itself is safe, repeatedly used oil is no
longer safe. Harmful substances will be produced after being heated time after
time. Acrylamide and Benzopyrene, for instance, could always be two types of
harmful side-products from frying French fries and chickens. These two side
products are widely believed to cause cancer.
Health authorities in Xianyang, Yulin, and Xi'an, three local cities of
Shaanxi Province, have inspected KFC outlets and confiscated their "oil powder".
The provincial health administration has also reported the case to the Health
Ministry for further investigation.
In similar response, local health authority of southern China's Guangzhou,
has also decided to inspect cooking oils in all KFC outlets in the city.
This is the third time KFC has been involved in food safety panic in China.
In March 2005, Sudan 1, a kind of carcinogenic food dye, was discovered in New
Orleans roast chicken wings, a popular food produced by KFC. Last November,
KFC's safety scare emerged again in China after KFC outlets in the US were found
to be using artificial fats although KFC Corp (China) said then it cooked its
fried chickens in a healthier edible
oil, which did not contain the harmful trans-fatty acids used in
US branches of KFC.
