UTILIZATION OF WASTE TOMATO SEEDS AND SKINS. 13 



be reduced to two products, namely, fixed oil and meal, each of which 

 may be made commercially useful. 



The oil from the seeds should find ready disposal as an edible oil 

 or as a soap oil, as shown by the experiments made to determine its 

 applicability to these purposes. By proper treatment it can be made 

 useful as a drying oil for paint and varnish purposes. 



The meal has been shown by analysis and comparison with other 

 meals to possess valuable qualities as stock feed, and the utility of 

 the meal for this purpose should therefore be assured. 



The accumulation of tomato residues occurs principally in two sec- 

 tions of the United States, namely, the North-Central States lying 

 east of the Mississippi and north of the Ohio Rivers and the North 

 Atlantic States. The reduction of this waste material to oil and 

 meal could be handled most logically by establishing reducing plants 

 at some central point in each of these sections, where the crude ma- 

 terial could be collected with the least expense for transportation and 

 handling. A cooperative plan of manufacture would perhaps be the 

 most feasible and effective method for establishing the industry upon 

 a practical basis. 



In view therefore of the threatened shortage of fatty oils and in 

 the interest of food conservation, tomato refuse may be considered as 

 an available source for the manufacture of oil and oil cake. As the 

 demand for tomato products increases, the quantity of this waste 

 material will also increase, and it is suggested as an economic measure 

 of both agricultural and industrial importance that the utilization 

 of this material be considered.
