ness in handling the product. When proper attention is given to these 

 details a satisfactory product can be obtained, but it is in the exercise 

 of the care required that many packers have failed. 



Why should the manufacturer desire to turn his trimming waste 

 into pulp ? Tests made at various factories have shown that 30 per 

 cent or more of the weight of the tomatoes as received at the fac- 

 tory goes into the waste known as trimmings. An examination of 



ordinary trimmings 

 (jawrass) shows them to consist 



of: (a) the skins from 

 peeled tomatoes; (6) 

 the steins and coarser 

 part of the cores from 

 around the stem end of 

 the fruit; (c) the de- 

 cayed and rotten parts 

 cut out from the other- 

 wise good fruit; (d) 

 tomatoes wholly de- 

 cayed; and (e) small 

 tomatoes, and others 

 of such size or shape 

 that it would be un- 

 profitable to skin them. 

 If the trimmings were 

 in good, clean condi- 

 tion, it is probable that 

 no serious objection 

 could be raised against 

 pulp made from (a), 

 (b), and (<?), provided 

 the packages were 

 properly labeled to in- 

 dicate the origin of 

 the product. 



Figure 2 shows 

 graphically a system 

 for manufacturing 

 pulp from tomato 

 trimmings. Although when properly handled such a sj^stem should 

 give a satisfactory product, it is complicated, and the extra labor 

 required in the use of trimmings in the pulp may not in average 

 seasons be compensated by the value of the product resulting. 



Because of the fact that a considerable part of the waste comes 

 from small tomatoes which the peelers find it unprofitable to skin,
