Vinegar pickled garlic is different from coarse salt pickled vegetables. The pickled vegetables will produce a certain amount of nitrite during the fermentation process, but when pickled with vinegar, you only need to wait for the macromolecules of vinegar to enter the material structure and make the garlic Has the aroma of vinegar, but not the long fermentation process required for pickling.

Secondly, sugar refers to white sugar, which does not react with vinegar and does not contain the nitrogen necessary to form nitrite.

In addition, garlic itself does not contain nitrite. Even if it does, vinegar cannot react with it because the acidity and nitrite of vinegar are very weak. In summary, if you only add vinegar and sugar , nitrite cannot be produced.

Extended information:

Nitrite poisoning is caused by the consumption of nitrate or bacon products, pickles and spoiled vegetables with high nitrite content, or the misuse of industrial nitrite It is caused by sodium as salt.

It can also be seen that after drinking brackish water and boiled water containing nitrate or nitrite, nitrite can remove the methemoglobin that is carried by normal oxygen in the blood. Oxidized to methemoglobin, it loses its oxygen-carrying capacity and causes tissue hypoxia.

It is worth noting that high doses of nitrite can still be very toxic. Eating nitrite by mistake can lead to nitrite food poisoning.

Long-term use can even cause esophageal and gastric cancer. Moreover, scientists still lack clinical trials to prove that nitrite can treat heart disease and other diseases. Therefore, scientists are actively recruiting volunteers for clinical trials and are beginning to look for suitable drug manufacturers to develop nitrite drugs.
