Some soybean products test positive for H2O2
The Consumers’ Foundation ( ) has said it has sampled 50 soybean products from traditional markets this April and said that six samples tested positive for hydrogen peroxide (H2O2).
The Foundation said it tested products on sale in Greater Taipei, Greater Taichung, Nantou County and Kaohsiung City at a press conference it held yesterday.
An annual inspection of food products was conducted in April of this year. There were 50 various samples collected: 20 dougan products ( ) , 12 gansi products ( ) and 100 tofu skin ( ) , 11 packaged soybean products, 5 tofu products and 2 vegetarian soybean products, according to the Consumers’ Foundation.
Six dougan and gansi products tested positive for hydrogen peroxide. The six samples are all bulk commodities.
“As a food additive, hydrogen peroxide can be used for fishrefined products, except for flour, other prepared goods and foods,” said the foundation, citing the Food and Drug Administration.
Food additives containing fungicide hydrogen peroxide occur when hydrogen peroxide oxidizes into water and oxygen molecules. The oxygen produced by oxidation can suppress microbial breeding, extend shelf life, and make the appearance of products seem whiter. However, if too much is added into a product, there may be residue in the food. When consumed, symptoms such as nausea, vomiting, abdominal pains or diarrhea may occur, said the foundation.
The six dougan and gansi violated the “Food Safety and Health Law,” under which more than NT$30,000 may be fined. Those fined less than NT$30,000 can appeal to authorities.
In October 2013, the Public Health Department of New Taipei City ( ) announced three of 80 batches of the sampled soybean commercial products tested positive for hydrogen peroxide. The detection rate was 3.75 percent, said the foundation at the press conference.
However, a year later, 16 commercial soybean products tested positive for hydrogen peroxide out of 101 samples, according to another examination by the Public Health Department in August 2014. The test was conducted in the months of May and June 2014. The detection rate was 15.8 percent, said the foundation.
In comparison to the detection rate and contaminated samples of 2013, the number of samples with hydrogen peroxide increased in 2014.
The foundation reminds the public not to purchase or consume soybean products that appear very white.
