PAPRIKA. 



By Sidney May, Phar. D. (N. Y. C. P.) 

 (Continued from April Issue.) 



The determination of the Iodine Number of the Ether extract is 

 perhaps the most important one, as consideral^le Paprika that is 

 imported is adulterated with olive oil. The addition of olive oil 

 deepens the color by 50%, the spice being bought by color and 

 flavor, chiefly by color. The method of determining is as follows : 



Two (2) grammes of the ground Paprika are extracted on a dried 

 filter with anhydrous ether, collecting the ether extract in a tared, 

 ground glass-stoppered Erlenmyer flask; remove the ether by dis- 

 tillation at low temperature, dry the extract in a water-jacketed 

 oven for about half an hour. The flask is then removed and allowed 

 to cool in the air and weighed. This operation is carried on until 

 the extract ceases to lose more than one milligramme. The ex- 

 tractive matter is dissolved by the addition of 10 c.c. chloroform : 

 30 c.c. *Hanus Iodine solution are then added and the flask allowed 

 to stand for 30 minutes ; 10 c.c. of a 15% solution KI are next added 

 and the contents of flask are shaken. Then 125 c.c. of distilled 

 water are added and the mixture titrated against Nio NasSaOs in 

 the usual manner. 



The iodine number of the ether extract as prepared above should 

 not be less than 130; this is for the whole pods, excluding the stems. 



The method used for the detection of artificial coloring matter is 

 tliat of Sostegni and Carpenteri, and is as follows: 



To 30 grammes of the sample add 150 c.c. of water, then 5 c.c. of 



<fo HCl. Immerse^a'piece of silk or wool (which has previously 



•Hanus Iodine solution. — Dissolve 13.3 grammes of iodine in 1000 c.c. glacial acetic acid C.P., add 

 enough bromine to double the halogen contents determined by titration, (about 3 c.c. is sufficient). 

 Dissolve the iodine in the glacial acetic acid, when all has dissolved, add the bromine.
