Modification of Richmond's formula for the estimation of solids -not fat in milk using specific gravity lactometers

By: Sharma,N.
Publisher: Karnal NDRI 1979Subject(s): Dairy-ChemistryDissertation note: M.Sc. Thesis Kurukshetra University 1979 B.S.Bector Summary: In the present investigation an attempt was made to modify the existing pichmond's formula using fat value astimated by gerber method and quevenne and Zeal specific gravity lactomethod. The results obtained ere compared with the SNF obtained by substracting the fat determined by rose gottlied gravimetric method from total solids estimated by over-drying gravimetric method (SNFG) fat determined by gerber methods (FC) has also been compared with the fat obtained by rose-Gottlied (FR). The results indicated that FG gave almost the same results as that of FR in milk samples having a fat range of 2 to 4% and 6 to 7%. The SNFQ and SNFZ up to arange of 9.0 and 8.5% SNF, respectively above which the values were found to underestimate the SNF contant. The study farther revealed that when the correction tables were analyses and applied to the respective existing formula, it was observed that the values obtained were in close agrement to those estimated by SNFG.
