Vinegar has no degree, and the total acid content of vinegar is commonly used. Generally, it is recommended to use vinegar ≥3.5g/ 100ml.
Degree is a unit divided according to certain standards, but there is no unified standard for vinegar, because vinegar is divided into brewing vinegar and blending vinegar.
Jiudu is named for its total acid content of 9g/ 100ml. Due to the limitation of production technology, fermented vinegar generally takes 3.5 as the high standard and 9 as blended vinegar.
As we know, the health care function of fermented vinegar has always been recognized by the health care industry, while blended vinegar is generally regarded as a condiment, which is very different, because brewed vinegar contains a variety of amino acids, minerals and vitamins, which has the health care functions of softening blood vessels, antibacterial disinfection and so on.
However, the total acid content of the prepared vinegar is high, which is beneficial to the preservation of vinegar and is not easy to deteriorate. At the same time, according to the relevant national standards, the brewing component of the brewed vinegar is not less than 50%, which means that the highest content of the brewed vinegar can reach 50%, and the 9-degree vinegar also has health care function, but it is a bit exaggerated to say that it is a special health care vinegar.
