To determine whether the juice meets the standard set forth in Section 1464.3, select sample containers from the lot at random in accordance with Section 1370.8. Take 10 percent of the fruit at random from each container.

When the lot to be tested is in bulk, select the number of pomegranates which would have been selected if the pomegranates had been packed in standard container No. 22C as defined in Section 1380.19.

Extract, combine, strain, and thoroughly mix the juice from the pomegranates selected for the sample. Place 10 c.c. of juice in a flask. Add 100 c.c. of water and 10 drops of phenolphthalein indicator solution. With the use of a pipette, add sodium hydroxide solution (.1562N). As sodium hydroxide is added, the reddish color of the juice will turn white and then to a pink shade. When this occurs, divide the amount of sodium hydroxide used by ten to determine the percent of acid.
