Abstract
Vinegar having an acetic acid content of 18-20% is produced by aerobic bacterial oxidation of ethanol in a combination of semi-continuous fermentation and batch fermentation. The semi-continuous fermentation provides 10-12% vinegar, a portion of which is then converted to 18-20% vinegar in a batch fermentor operating at a temperature substantially lower than that employed in the semi-continuous fermentation. Gas is admixed with the fermentation mixture prior to its being subjected to microfiltration or ultrafiltration during its transfer from the semi-continuous fermentor to the batch fermentor.
