One of the major users of potassium sorbate is the wine making industries. Potassium sorbate is used as a wine stabilizer because when it is added to the wine, it produces sorbic acid which is the active agent that inhibits the growth of yeast. The remaining yeasts present in the wine would continue to ferment any residual sugar into alcohol until their death. It is also used to prevent the re-fermentation of these wines. Potassium sorbate is commonly used at concentrations between 0.025% and 0.1% in the food and wine industries. It is most active in slightly acidic mediums; the pH must be low enough to enable the release of free acid that is required for efficient activity.
Sodium bicarbonate has been recognized for its health benefits in food preparation. In addition to its role as a leavening agent, it may also improve the digestibility of certain foods. By neutralizing stomach acid, sodium bicarbonate can alleviate symptoms of indigestion and heartburn when consumed in moderation.
