Sweetened Condensed Milk — Striking 91 



or if it is desirable to convert them into specific gravity, the con- 

 densed milk should have a temperature of 60 degrees F. Where 

 this is not convenient, the observation may be made at any tem- 

 perature convenient and the reading corrected as follows : 



When the temperature is above 60 degrees F. multiply the dif- 

 ference between the observed temperature and 60 degrees F. by the 

 factor . 025 and add the product to the observed reading of the 

 Beaume hydrometer. When the temperature of the observed read- 

 ing is below 60 degrees F. the corresponding product is deducted. 



Example: Beaume reading at 120 degrees F. is 31.2. Cor- 

 rected reading is 31.2 + [.025 X (120 — 60)] = 32.7. 



The specific gravity may be calculated when the Beaume read- 

 ing is known, by using the following formula :

Example: Beaume reading, at 60 degrees F. is 33.1.

In the following table are assembled figures showing the spe- 

 cific gravity of sweetened condensed milk of different Beaume 

 degrees, varying from 28 degrees B. to 37.8 degrees B.
