As is the case with wines, alcohol-free beverages made from grapes require the use of a stabilization process in order to prevent the product from being altered.
The majority of producers of alcohol-free beverages made from grapes have opted for cold sterilization. This process consists of adding dimethyldicarbonate (DMDC) to the product in order to deactivate the enzymes that are vital for micro-organisms and therefore cause them to die.
DMDC is used as a preserving agent (E242) as it has been proven to be effective. However, when it breaks down in the product it is transformed not only into carbon dioxide but also into methanol, a very dangerous substance for man.
As a result of an enzyme present in the liver, the methanol is transformed into formaldehyde which has been named as a ‘carcinogenic substance for man’ by the International Agency for Research on Cancer (IARC).
The symptoms of intoxication from this substance are headaches, dizziness, nausea, impaired vision and, in extreme cases, death.
In view of the fact that fetal tissue is highly sensitive to the effects of methanol, it is advised avoid contact with it.
It is for this reason that the Pierre Zéro alcohol-free drinks brand refuses to use chemical products and has instead opted for the natural pasteurization of its entire range. This guarantees the consumer a 100% natural and healthy product with no chemicals.
