Report Introduction: The manufacture of tomato products in the United States constitutes an industry of large and growing proportions and importance. Tomatoes serve as the basis for two general classes of products, in one of which the fresh whole tomatoes are used and in the other the pulp alone, as in the manufacture of catsups and soups. For this latter class large quantities of tomatoes are required, from which the seeds and skins at present are discarded as useless. The increased interest in the production of foodstuffs throughout the country will doubtless result in an extension of all canning and packing operations, including tomato products. In the following pages attention is directed to the possible utilization of the waste tomato material, not only from the standpoint of food conservation, but as a profitable adjunct to the tomato-canning industry.
