The manufacture of tomato pulp requires careful supervision from
beginning to end. The raw product must be carefully selected, and all
possible steps should be taken to induce growers to discard rotting
tomatoes in the field and to expedite the movement of the raw product
from field to factory. Tomatoes must be carefully washed and sorted. It
is only practicable to accomplish the latter by means of some type of
sorting belt. Sorters should not attempt to trim. Their full attention
should be given to the tomatoes passing by them. The sorter may place
the tomatoes requiring trimming in a separate receptacle in order that
they may be carried to a table not provided with a moving belt and
handled by special trimmers. Conveyors, receptacles and machines must
be constructed and installed with a view to convenience in cleaning.
Care must be taken to expedite the manufacture of the product in every
way possible in order to give no opportunity for bacterial growth
during the process of manufacture.
The brief comments given above are offered by way of reminder.
This important subject is not further discussed because it has
been adequately treated by Mr. B. J. Howard of the U. S. Bureau of
Chemistry in bulletins which are readily available. These bulletins
are designated as Bulletins 569 and 581, respectively, of the United
States Department of Agriculture. They may be secured by requesting
them of the Superintendent of Documents, Government Printing Office,
this city, and enclosing five cents in coin for each copy desired. All
manufacturers of tomato pulp will do well to study these bulletins and
have them studied by their responsible employees.
