Ohio Respiration and Associated Factors as Indices In the 



Deteriiination of the Period of Marketability (Shelf Life) of 

 Fresh (Unprocessed) Fruits and Vegetables . To determine (ij 

 the rate of respiration and veight loss of fresh fruits euad 

 vegetables imder the conditions normally encotintered in 

 retail and wholesale distribution; (2) optimum conditions 

 for storing and handling fresh fruits and regetables through 

 the study of various packages and controlled temperature 

 and htimidity ranges; (3) maximiaa holding period for fruits 

 and vegetables under varioiis controlled conditions; (k) 

 through chemical analysis the changes which occvir in fresh 

 fruits and vegetables during the holding period in relation 

 to reducing sugars, total sugars, fiber, or other measurable 

 material changes; and, (5) effect of the source of fresh 

 fruits and vegetables (information on growing environment 

 and early post-harvest handling) on the respiration rate 

 and qtiallty of these fresh fruits and vegetables,

R. I, Certain Factors Influencing Keeping Quality of Tree 

 Fruits in Storage^ To determine (1) effect of initial 

 ceirbon dioxide treatment of fruits on subsequent storage 

 behavior; (2) relationship between vapor pressure deficit 

 of the air and transpiration rate of apples as affected by 

 varioxos treatments; (3) relationship between cutln and 

 scald develoianent, respiration, and trcmspiration of apples; 

 and, (k) effectiveness of various pre- and post-storage 

 treatments on scald development and keeping quality.

Wash, Harvesting and Handling Freestone Peaches to Improve 



Uniformity and Quality for Canning . To (1) learn source and 

 extent of handling damage to freestone peaches destined for 

 processing; (2) reduce amount of handling damage; euid, (3) 

 provide fruit of more tiniform maturity for canning throii^ 

 improvement of harvesting and handling methods.

Calif. Economic and Engineering Studies of Pcusking House Prac- 

 tices" Economic studies will include labor input incentive 

 systems, time and motion studies, and such other investigations 

 as may be needed to improve work efficiency, working conditions, 

 and physical efforts of employees. Engineering studies will 

 include analysis of the flow of materials throxogh the packing 

 house and storage rooms, fruit handling equipment, disposal of 

 products, by-products and wastes, efficiency of mechanical equip- 

 ment, and analysis of operations which may lead to equipment 

 improvement, labor reduction, and lower operating costs,
