Tomato products
For chili sauce the tomatoes are peeled as they are for canning. As a
rule they are run over a grader and only the large ones are used for
peeling, the small ones being pulped or made into catsup. It does not
pay to peel the small tomatoes, as it requires too much labor, and the
women who do the peeling at so much per bucket try to fight shy of them,
and often mash them up in their buckets to avoid having to peel them.
They will make just as good pulp or catsup as the large tomatoes will,
and much more can be got out of them in this way than if an attempt is
made to get them peeled.
Sometimes the small tomatoes and the peelings of the large tomatoes are
pulped together. If this is done the whole small tomatoes tone up the
flavor of the peelings, and also help to keep the final product within
safe limits as to microscopical count.
Some packers throw away the peelings, either because they are so busy
with the whole tomatoes that they can’t bother with them, or because
they are afraid the pulp which they are worked up into will run high in
micro-organisms, and they don’t want to have such pulp on their hands.
Method of Handling Tomatoes
The usual method of handling the tomatoes is to run them first over a
sorting belt, where they are inspected by several women, then over a
grader, which lets the small tomatoes fall through on to a belt which
conveys them to a washing arrangement, and thence to the “breaking
tanks,” or to the pulp machine, or the crusher, depending upon which
pulping method is used. The small tomatoes may or may not be given a
second sorting.
If the trimmings are to be thrown away, the large tomatoes don’t need to
be sorted, as the peelers will take care of that, and in this case a
good way is to put all the tomatoes through a rotary washer first, then
over a grader, and have the small tomatoes carefully sorted after the
grading is done. The large tomatoes pass from the grader to the scalder,
and thence to the peeling table or “merry-go-round,” where they are
peeled.
The best method to use if the trimmings are to be pulped will be
discussed later in the chapter.
The peeled tomatoes are thrown into a cutting machine which cuts them
into good-sized chunks, and drops them on a bucket conveyor which takes
them to the cooking kettles. The cutter should be so adjusted that it
will not make the tomatoes mushy. A few fair-sized pieces of tomato in a
bottle of chili sauce is nearly always pleasing to the consumer.
It is important that the peeling be thorough. Each bucket should be
inspected before the tomatoes are thrown into the chopper. Pieces of
peeling in chili sauce are very noticeable when the product is used, and
make an unfavorable impression.
