The prolonged pasteurization of milk as carried out in the dairy industry, 

 viz, heating for from 20 to 30 minutes at from 140 to 147.2° in apparatus 

 maintaining it in continual motion, is deemed sufficient to remove all danger 

 of the conveyance of tuberculosis by means of milk. 



Studies on Swedish Emmental cheese and large-eyed Swedish cheese 

 (Herrgardsost), L. F. Rosengken and E. Haglund (A'. TMUdthr. Akad. Eandl. 

 och Tidskr., 53 {1914), No. 7, pp. 485-526, figs. 8).— In these studies a marked 

 difference was found between the Swedish Emmental and Herrgard cheese: 

 Much the larger amount of amino acids was formed in the Swedish Emmental 

 cheese during ripening. 



In both cheeses the volatile fatty acids were formed mostly from acetic 

 and propionic acids. The content of such acids was generally smaller in 

 cheese with weak eye-formation than in cheese with strong eye-formation. 

 The sweet-bitter cheeses contaui an abnormal quantity of butyric acid. A 

 large amount of salt decreased the content of volatile fatty acids substances 

 in the Swedish Emmental cheese, and the addition of saltpeter decreased the 

 content in both cheeses, especially the propionic acids. The addition of salt- 

 peter to the milk often gave a taste of saltpeter to the cheese and spoiled its 

 color, but can control too rapid fermentation. 



Cheese making, C. L. Stahl {Va. Dairy and Food Div. Bui. 59 {1916), pp.

The utilization of sucrose and the inverting power of the blood serum 

 after parenteral administration of sucrose, S. Kueiyama {Jour. Biol. Chem., 

 25 {1916), No. 3, pp. 521-547). — "In correspondence with earlier observa- 

 tions . . . sucrose, administered parenterally to dogs, was not eliminated 

 quantitatively in the urine. The amount recovered varied considerably, aver- 

 aging 76 per cent when sucrose was injected in doses of from 0.4 to 0.9 gm. 

 per kilogram of body weight. The elimination was usually concluded within 

 24 hours. The degree of utilization was essentially the same for the different 

 paths of parenteral introduction of the sugar. The apparent utilization of a 

 small part of the sucrose, as judged by its failure to be excreted by the kid- 

 neys, may be due to the presence or rapid production of sucrose in the 

 blood. . . . 



" Experiments in vitro showed that the inverting power of active yeast or 

 intestinal extracts was not lost in the presence of defibrinated blood or serum, 

 although it was considerably decreased. Addition of acid facilitated the in- 

 vertin reaction and therefore was carried out in some of the experiments with 

 serum. 



" That the activity of sucrase is retained in the circulation itself was shown 

 by the results of injecting solutions of active yeast invertin ; for under such 

 conditions injected sucrose failed to reappear in as large amounts as usual. The 

 better utilization was not due to any failure of the kidney functions in eicret-
