Condensed Milk Testing. 
Materials necessary for 10 students: 
5 250 cc. flasks. 
EXERCISE NO. 49 
Object: To determine the fat content of unsweetened condensed milk by 
means of the Babcock test. 
Procedure: Due to the condition of the milk, the sugar that may he pres¬ 
ent, etc., it is very difficult to test condensed milk for fat. 
The following method is, however, suggested for unsweet¬ 
ened condensed milk. 
A. Exercise great care so as to obtain a representative sample 
from the can of milk. Dilute 25 cc. of condensed milk with 
75 cc. of water, making 100 cc. Test as for whole milk, but 
fill the bottle after the first and second whirling with a hot mix¬ 
ture of acid and water 1:1. Read as for milk. 
B. Calculate the per cent fat as follows:

Note 1: In order to get a good sample, it may be necessary 
to heat the sample to 130° F. for 10 minutes, and then shake 
well before opening the cans. 
Note 2: If sweetened condensed milk is to be tested the plan 
of Exercises 46 to 47 may be followed.
