A simple procedure for the rapid determination of the total acidity in wines and fruit juices was patented by Holzbach (1936). He prepared alkaline pieces of filter paper corresponding to 0.05% to 0.01 % acid, which he added to the solution. Bromocresol was used as an indicator, and from the number of pieces of alkaline paper added the acidity was calculated. A simple blue patented German indicator, useful for aU except the medium-to-dark red wines, was employed by Larsen (1961). Indicators, such as acridine and umbeUiferone, which are fluorescent in ultraviolet light for the end point in the acidity determination, were proposed by Volmar and davera (1931). One advantage of these was that they can be used in red wines. [Pg.390]
