ABSTRACT
The curd tension of milk, while probably not wholly satisfactory as a measure of digestibility and suitability of milk for infant use, nevertheless has been tacitly accepted as an indication of these characteristics. The recent action of the Council on Foods of the A.M.A. in "accepting" homogenized milks with soft curd claims and establishing a limit of 20 grams tension for such milks has further added to the repute of the curd tension value. Some municipalities have set, or are contemplating establishing, curd tension standards for homogenized milk, the production of which is increasing rapidly. It seems particularly desirable, therefore, to publish the procedure for making curd tension determinations which was approved at the Thirty-sixth Annual Meeting of the American Dairy Science Association, June 1941.
DETERMINATION OF THE CURD TENSION OF MILK
Reagent
The coagulant consists of .08 N hydrochloric acid to which U.S.P; (1:3000) dry pepsin has been added at the rate of 450 mgms. per 100 ml.
