SANITARY CONTROL OF TOMATO-CANNING FACTORIES. 99 
Trimming and sorting should be made separate operations. 
It is very difficult to make sanitary pulp from trimmings alone 
and its manufacture is of doubtful profit even when properly done. 
It is possible to arrange a system of manufacture by which the 
rotten trimmings can be wholly discarded and the pulp made from 
good trimmings and small tomatoes. 
The percentage of decay in the sorted stock should be 1 per cent 
or less. ‘ AG 
Prompt handling is essential if spoilage is to be avoided. 
Too much care can not be given to cleaning. Every piece of 
apparatus in the factory should be arranged conveniently and plenty 
of cleaning equipment should be available. The best results are 
obtained when the cleaning is highly systematized and each worker 
is made responsible for his part in it. 
Laboratory methods of checking the character of the finished 
products have been found of great value.
