BULLETIN 282, U. S. DEPARTMENT OF AGRICULTURE. 



Regarding, first, the sulphured hops, the data in Table II show 

 that the percentage of soft resins decreased somewhat during the 

 first and second years of storage and very rapidly during the third 

 year. The decrease was less, however, in the cold-storage samples 

 than in those kept hi open storage. The unsulphured hops show a 

 marked decrease from year to year, the decrease being most pro- 

 nounced in the third year of storage. The unsulphured samples in 

 open storage show a greater loss than the corresponding samples 



kept in cold storage. 

 During the first year 

 of open storage the 

 soft-resin content in 

 the sulphured hops 

 decreased less rap- 

 idly than in the un- 

 sulphured hops, but 

 more rapidly in the 

 following two years. 

 It will be observed 

 from figure 1 that 

 the quantity of soft 

 resins present in the 

 sulphured hops in 

 both cold and open 

 storage decreased 

 during each year and 

 that the decrease was 

 especially marked 

 during the third year 

 of storage. Figure 1 

 also shows that the unsulphured hops in cold storage decreased in 

 soft-resin content more rapidly than the sulphured hops and that 

 this decrease was rapid during the first year, less pronounced during 

 the second year, and at the end of the third year gradually ap- 

 proached the same point of value as in the sulphured hops in cold 

 storage. The soft-resin content of the unsulphured hops in open 

 storage decreased at about the same rate as that of the sulphured 

 hops in open storage. 



The percentage of decrease in soft resins during the three years, 

 as compared with the original samples, is given in Table III.
