The most common buffer solutions used for calibration are pH 7 and pH 4 but pH 10 is also available. 1 Answer. The acid content of the must is determined by titrating a sample (a given volume) with a base such as sodium hydroxide solution to a phenolphthalein end point or alternatively, to a pH of 8.2. A pH meter substitutes for the color endpoint. The acid itself is added to foods as an antioxidant E334 and to impart its distinctive sour taste. TA = (Number or milliliters of NaOH / Number of milliliters of juice) X 0.75 The units for the TA in this calculation are: Number of grams of tartaric acid per 100 milliliters of juice.
