MOLASSES AND SmUVS— Continued. 



Since pure maple sirup consists largely of ordinary sugar, the direct 

 detection of added sugar sirup is, of course, impossible, but its pres- 

 ence is easily shown by the determination of minor constituents 

 which occur in maple products only. With basic lead acetate a 

 copious precipitate, in proportion to the amount of the maple product 

 present, is deposited. 



Seven samples of maple sirup and maple sirup substitutes were ex- 

 amined, two of which were found to be true maple sirups unadulter- 

 ated ; four were adulterated with cane sugar sirup, and one was 

 labeled so as to indicate its compound nature. 



It was claimed by the dealers that they had had these adulterated 

 sirups on hand for a long time, probably before the National Food 

 Law went in effect.
