In a 100 mL (3 + 1 ⁄ 2 US fl oz) reference amount, distilled vinegar supplies 75 kJ (18 kcal) of food energy and no micronutrients in significant content. [44] The composition (and absence of nutrient content) for red wine vinegar and apple cider vinegar are the same, whereas balsamic vinegar is 77% water with 17% carbohydrates, 370 kJ (88 ...

Water activity ( aw) is the partial vapor pressure of water in a solution divided by the standard state partial vapor pressure of water. In the field of food science, the standard state is most often defined as pure water at the same temperature. Using this particular definition, pure distilled water has a water activity of exactly one.
100 mg of sample tannins are dissolved in 10 ml distilled water. 1 ml of 10M HCl and 2 ml of 37% formaldehyde are added and the mixture heated under reflux for 30 min. The reaction mixture is filtered while hot through a sintered glass filter. The precipitate is washed with hot water (5× 10 ml) and dried over CaCl 2. The yield of tannin is ...
