Vinegar is the product obtained exclusively through biotechnological processes such as double fermentation, alcoholic and acetic fermentation of liquids or other substances of agricultural origin there are various types of vinegars obtained from. Vinegar is a living ingredient created through the process of fermentation the final product will contain elements of the original stock, which add a depth of flavor that differentiates a naturally fermented vinegar from a manufactured one.
During simultaneous pineapple vinegar fermentation (spvf), it was observed that there vinegar is very important food preservative in food was a positive effect of oxygen on yeast- m30’s ability industry. Vinegar may be defined as a condiment made from various sugary and starchy materials by alcoholic and subsequent acetic fermentation (cruess 1958) vinegar can be produced by different methods and from various raw materials wine (white, red, and sherry wine), cider, fruit musts, malted barley, or pure alcohol are used as substrates.
Slow fermentation process, which was done in this experiment or the generator process can be substituted with other faster methods using a more efficient fermentor like in submerge processes which can produce vinegar with an acid strength of 12% or more in a shorter period of time. Vinegar may be defined as a condiment made from various sugary and starchy materials by alcoholic and subsequent acetic fermentation (cruess 1958) vinegar can be produced by different methods and from various raw materials. Cellular respiration and fermentation: experimenting with co2 and redox reactions julius engel section 8 abstract in this experiment, the subjects of study were fermentation, mitochondrial respiration, and redox reactions. This study aimed to reduce post-harvest losses of pineapple local variety egbenana by the transformation of juice into vinegar through biotechnological processvinegar was produced through two successive fermentations: alcoholic and acetic fermentations.
Acetic acid fermentation is done in a sugary medium it is consists of the fermentation of alcoholic substrate to acetic acid by aceti bacter or vinegar bacteria bfad defines that vinegar should contain 4% acetic acid expressed as lactic acid. The term vinegar actually refers to the two-step process of fermentation from a carbohydrate to an alcohol to an acetic acid sugar is converted into alcohol, which is then fermented into vinegar not all acetic acids are vinegar, although all vinegars are made from acetic acid.
Sossou, ameyapoh, karou, and de souza (2009) observed that the ph decreased from 440 to 290 during acetic fermentation and the acidity degree increased with the fermentation time, so outlining an inverse linear correlation between the evolution of acetic acid and the ph during vinegar production.

Vinegar is the product of a two-stage fermentation in the first stage, yeast convert sugars into ethanol anaerobically, while in the second ethanol is oxidized to acetic (ethanoic) acid aerobically by bacteria of the genera acetobacter and gluconobacter.
