Last week, the European Union published a document to say that according to their reassessment, the aluminum sulfate and sodium aluminum acid phosphate used as food additives are safe under the current standard.
In this document, the aluminum sulfate is allowed to use for processing eggs and egg products. This additive is usually used as stabilizer of albumin pasteurization in the production of frozen egg products. And the sodium aluminum acid phosphate can be only used in exquisite baked goods.
However, many aluminum-containing food additives have been prohibited in China since 2014, including sodium aluminum acid phosphate which can not be used in the production and processing of any food in the light of national regulations.
There is a consistent view in the academic community that aluminum primarily affects the health of bone and nervous system. And some investigations also showed that this element was related to Alzheimer, but people didn’t reach a consensus.
However, this is not the reason why three (sodium aluminum acid phosphate, sodium aluminium silicate and aluminum starch octenylbutanedioate) aluminum-containing food additives are forbidden and two (aluminium potassium sulfate and ammonium aluminum sulfate) are limited to use in China. The reason was excessive intake of the aluminum. Some food manufacturers violated the original regulations and used the additives in more than the limited amount, so Chinese government has issued more stringent restrictions.
In 2011, some experts from the United Nations and World Health Organization determined the “provisional tolerable weekly intake” (PTWI) for aluminum as 2 mg per kilogram of body weight per week.
Therefore, we can tell that, the reasonable use of the aluminum-containing food additives within the limit will not cause great damage to the health, and on the contrary, these additives may help make the food more fresh and delicious.
