Among the conditions in the method to estimate curd tension the pH of curdling solution is an important factor. PH of the mixture of milk and enzyme solution by the ordinary curd tension measurement is maintained at 6.2, whereas pH of stomach content of infant after 2 to 4 hours from milk ingestion is 5 to 5.5. To estimate the coagulability of milk in the stomach of infant, the authors recommend that 20 ml. instead of 10ml. of digestion mixture containing pepsin and hydrochloric acid should be added to 100ml. of milk. Even in this case human milk does not coagulate, while many milk products for infant fee ding coagulate distinctly. Spur's method of physiologic tension is the most suitable in these cases.
