Methods of detection need to be improved

WUHAN - With the inefficiency of current techniques for detecting and identifying the use of illegal cooking oil in China, there is an urgent need to improve kitchen waste recycling procedures to prevent the continued use of such oil in food production, a leading food expert has said.

He Dongping, a professor of food science engineering at Wuhan Polytechnic University (WHPU), revealed last Thursday that one in every 10 meals in the country might have been cooked with dirty oil based on an ongoing study.
