PROFITS FROM MANUFACTURE OF ICE CREAM 213 



Suppose Tahiti beans at $2 per pound are substituted for the 

 Mexican vanilla bean, the material cost of a gallon of vanilla 

 extract will then be reduced to $3.53. 



An extract resembling vanilla extract and often sold for 

 vanilla extract is manufactured synthetically and its cost of 

 production is much less than the cheapest true vanilla extract 

 manufactured. Therefore, in purchasing vanilla extract, 

 the writing on the label of the bottle should be carefully read 

 and at times a sample of the goods might be sent to the State 

 Experiment Station for analysis. 



The extract made from the Tahiti bean is of a lighter color 

 than that manufactured from other beans and is therefore 

 readily distinguished unless artificially colored. 



Although it may appear to be profitable for the ice cream 

 manufacturer to manufacture his own vanilla extract, it has 

 been found by many who have attempted to do so in a small 

 way that they have not been successful in producing an extract 

 equal to the commercial product. 



B. Lemon Extract, Lemon extract, in accordance with 

 the United States standard, is the flavoring extract prepared 

 from oil of lemon or from lemon peel, or both, and contains not 

 less than 5 per cent by volume of oil of lemon. 



Oil of lemon is the volatile oil obtained by expression or 

 alcoholic solution from the fresh peel of the lemon, has an opti- 

 cal rotation 1 of not less than +60 in a 100 mm. tube and con- 

 tains not less than 4 per cent by weight of citral. 



The direction for preparing a tincture of lemon peel is as 

 follows: 



500 grams lemon peel from the fresh fruit in thin shavings 

 and cut in narrow shreds. 



Alcohol of sufficient quantity to make 1,000 c. c. 



"Macerate the lemon peel in a stoppered, wide-mouthed 

 container in a moderately warm place with i ,000 c. c. of alcohol 

 during forty-eight hours with frequent agitation; then filter 

 through purified cotton, and when the liquor has drained off
