Cranberry juice cocktail: why 271 g per cup is wrong
USDA SR Legacy "Beverages, Cranberry juice cocktail" (FDC 173214) publishes 271 g (9.6 oz) per US cup of cranberry juice cocktail. This site rejects that figure and publishes 253 g (8.9 oz) instead, from USDA SR Legacy "Cranberry juice cocktail, bottled" (FDC 171903) (density 1.0694 g/mL, matching the composition of the substance). The reason:
The record's own composition rules it out: it lists 236.8 g of water in the cup, and 236.8 g of water alone fills 237 mL, the whole cup, leaving no room for the 31 g of sugar it also lists. 1.145 g/mL is the density of a syrup of about 33% sugar; cranberry juice cocktail is 12 to 16 °Brix. USDA's other cranberry juice cocktail record weighs a cup at 253 g, Health Canada at 253.6 g, and USDA's measured specific gravity is 1.05.
