FOOD INSPECTION. 191 



Strictly pure maple sugar and strictly pure maple sirup carry- 

 ing not less than 65 per cent solids may be lawfully sold 

 unbranded. All other maple products must be labeled. 



A mixture of maple and cane sugar or sirup may be branded 

 "maple and cane sugar" or "maple and cane sirup" when the 

 maple product makes up half or more of the whole. It may be 

 branded "cane and maple sugar" or "cane and maple sirup" 

 when the maple constitutes from 10 per cent to 50 per cent of 

 the whole. If the maple constitutes less than 10 per cent of the 

 whole it cannot be branded as a "mixture," "compound" or 

 "blend" but must be labeled "cane sirup, maple flavor" or "cane 

 sirup, flavored with maple," or some similar name. 



In the case of all these compound maple goods the word 

 "maple" must be no more prominent than the others words in the 

 name. Misleading pictures or misleading descriptive matter are 

 unlawful. 



METHODS OF ANALYSIS USED. 



Total Solids. — 2 grams were put upon 2 to 3 grams shredded 

 asbeston (previously ignited) in a round, flat bottomed dish 

 three inches in diameter and dried in a steam oven at about the 

 temperature of boiling water until nearly constant weight was 

 obtained. 



Sucrose.- — -The normal amount for the instrument was polar- 

 ized before and after inversion and the percentage of sucrose 

 calculated by Clerget's formula. 



Lead Number. — In this determination the method described 

 by Winton and Kreider, Gen. Am. Chem. Soc. 1906, 28, 1204, 

 was employed and the percentage of maple given estimated 

 therefrom. 



Total Ash.-— 10 grams were burned in a platinum dish at a 

 low red heat until the carbonaceous matter was destroyed.
