Proceed as in 932.14C (see 44.1.04). % Soluble solids = % solids determined by refractometer × (100 − b)/100, where b = % H2O-insoluble solids.
(Note: U.S. Federal standards for frozen fruits, canned fruits, fruit jellies, and preserves make no correction for H2O-insoluble solids, invert sugar, or other substances.)
