Fruit Handling and Methods of Analysis 



The experimental fruit was grown at the Washington State College Tree Fruit Experi-

 1953, and the Golden Delicious on October 20. After harvest, the fruit was immediately 

 placed at 31° F. , where it was hand-sorted, sized, and composited^* The fruit was 

 packed in standard Northwest wooden apple boxes. Half of the apples in the boxes were 

 wrapped in oiled paper, and the rest were packed without wraps. All boxes were lidded 

 for ease of handling. 



The fruit remained in regular storage at 31° F. until November 3, when 7 boxes of 

 Golden Delicious and 8 boxes of Starking Delicious were placed in each of 3 sheet-metal
