FOODS AND FOOD ADULTERANTS. 



ADULTERATED WITH INVERTED SUCROSE. 



ANALYSES BY H. A. WEBER. 



The samples adulterated with glucose are the following, viz : Nos. 1, 

 4, 7, 11, 13, 17, 18, 19, 21, 23, 24, 25, 27, 33, 34, 35, 36, 44, 46, aiid 48. 



The labels characterizing the adulterated articles can be seen in the 

 foregoing description. Some of them have grown to be quite familiar. 

 No. 1 is " California Honey," No. 7 " McMechen's Old Virginia," etc. 



No. 13 was a spurious comb honey in ajar. 



No. 23 is labeled " Pure Machine Extracted Honey from the Italian 

 apiary of C. F. Muth & Son. 



No. 33, labeled " Pure California White Sage Honey from Thurber & 

 Whyland," shows an addition of a large quantity of dextrin, probably 

 in the form of glucose. 



It is to be regretted that Mr. Weber did not use the same methods 

 of detecting glucose adulterations as was practiced by the other analysts 

 engaged in the work. He has passed some samples as unadulterated in 

 which we should have expected to find large quantities of glucose, from 

 an inspection of the names and labels they bear. 



ANALYSES OF F. G. WIECHMANN. 



NOTES BY MR. WIECHMANN. 



The samples analyzed were liquid, " strained honey," excepting samples Nos. 140, 

 144, 148, 149, each of which had a piece of comb in the liquid, and No. 147, which was 

 comb-honey. 



In numerous samples a sediment appeared ; in sample No. 124 the contents of the 

 bottle had separated into halves, the lower portion being filled with a yellowish gray 

 solid, while above this stood a dark-brown solution. These were of course thor- 

 oughly mixed before analysis. 



In No. 106 a brown flocculent precipitate appeared throughout sample. 



All honeys having an ash of 0.30 and over were tested for calcium sulphate. These 

 were the samples :
