Summary 



In a test with regular storage Mcintosh, hand wiped fruit lost moisture more 

 rapidly at room temperature than unwiped apples. However, there was no difference 

 in flesh firmness as indicated by the pressure tester or any observable difference 

 except for cleanliness between the unwiped and wiped apples. CA Mcintosh, cloth 

 wiped by hand or machine, lost moisture no more rapidly at room temperature than 

 unwiped fruit. The placement of apples in polyethylene bags reduced their rate of 

 moisture loss at room temperature. 



Conclusion 



Careful cloth wiping of Mcintosh by machine or hand after storage should not 

 Impare keeping quality. Any wiping process to remove residue from apples should 

 be done carefully to minimize mechanical injury.

RESEARCH FROM OTHER AREAS 



Predicting Scald with Box Liners 



The Proceedings of the 100th Annual Meeting of the New York State Horti- 

 cultural Society contained an article by R. M. Smock titled "What Can We Do About 

 Storage Scald?". One of the topics discussed by Smock was predicting scald with 

 box liners. 



"Samples of quite immature (to encourage scald) apples were placed in un- 

 sealed polyethylene box liners and held at 70° for four to six weeks. The scald 

 was then counted. Comparable apples were placed in cold storage in open crates 

 in the conventional manner. These samples were held in cold storage for 5-6 

 months and scald was counted after an additional holding period of 7 days at 70 F. 

 The results with Greening, Mcintosh and Cortland were similar enough that they are 

 not kept separate by varieties in Table 1.
