Popis:	Consistency and serum separation were found to be unrelated quality attributes. When consistency was standardized to a given Bostwick level serum separation varied from none to considerable. Consistency was found to be directly dependent upon the fraction of water insoluble solids (WIS) of the total solids (TS) of the tomato pulp used. Serum separation was found to depend upon the break system employed. Retention of at least 80% of the tomatoes' original serum viscosity was required for minimal serum flow. The data suggested that serum separation best measures quality, whereas the percentage of water insoluble solids in the total solids of a pulp determines the ratio of tomato solids to sugar required to achieve a standardized consistency level, which makes this ratio a measure of yield. The data also indicate that automation of catsup making is possible provided the “yield factor” is determined by the method described, or the water insoluble solids and total solids contents of the pulp are known beforehand.
