COMPOSITION OF IJQUOR. 



The liquor used on peas is usually composed of water, salt, and 

 sugar. At one time saccharin was used by many packers instead of 

 sugar, but this practice has been almost entirely discontinued. The 

 proportion of salt and sugar used varies greatly with the different 

 packers. The lowest amounts given were 2 pounds of salt and 2 

 pounds of sugar to 100 gallons of water. The largest quantities used 

 were 40 pounds of sugar and 16 pounds of salt per 100 gallons, while 

 the average seems to be about 10 pounds of salt and 10 of sugar per 

 100 gallons of water. There is undoubtedly a tendency to reduce 

 the amount of sugar used, and a few canners have left out both salt 

 and sugar in some lots of peas to determine whether there is a marker 

 for an unseasoned product. The heavy sirups are used in the fancy 

 and extra fancy brands of goods, the amount of sugar added to the 

 sirup being often the only difference between the " superlatively 

 good " and the " best." A fairly sweet sirup is sometimes used to 

 give a weak, insipid, sugarless pea some semblance of quality, also 

 to make the smooth pea as sweet as the sweet wrinkled variety. 

 Analyses a of 35 brands of peas purchased in the open market show 

 the sugar content of the liquor to vary between 0.46 and 4.17 per cent. 

 the average being 2.62 per cent. More sugar is found in eastern than 

 in western packed peas, and in the domestic than in the foreign peas. 



PROCESSING. 



After being filled the can is passed through the wiping machine, the 

 cap is put on and soldered in the automatic capper, the tipping fol- 

 lows, and then comes the final inspection in the water bath for leaks. 

 At one factory the can> were passed through an exhauster for the 

 double purpose of heating them uniformly and of driving off a cer- 

 tain characteristic odor which is objectionable.
