Pears:
The three most common varieties of pears are Williams, Packham and Nashi. Harvest time and maturity is determined by the firmness of the fruit. All pears should be treated carefully at the time of harvest to avoid skin damage. Pears harvested at optimum maturity tend to be less susceptible to physiological disorders and to be able to ripen after storage. Pears lose moisture rapidly following harvest and during storage. Storing pears inPEAKfresh reduces the rate of dehydration and weight loss. Pears need to be cooled immediately following harvest to around -1ºC (30ºF). Delays in cooling shorten the storage life. For long term storage of pears, one recommendation is that the core temperature of the stored pears should be at around 0ºC (32ºF) within four days of harvest. PEAKfresh carton liners will extend the life of many pear varieties by between four and eight weeks by providing a modified storage atmosphere that is higher in carbon dioxide and lower in oxygen.
Recommended Post Harvest Temperatures
0ºC (32ºF) and Relative humidity 90 to 95%.
 
Packaging Method
Pears are producers of ethylene gas and suffer from moisture loss very quickly. Pears should be carefully handled following harvest and wherever possible hydro cooled with water to remove field heat. After pears have been dipped, they should be thoroughly dry before packaging. Pears destined for controlled atmosphere storage can be stored dry in bulk bins lined with a PEAKfresh bin liner. Pears that are destined to be packed for short term cool room storage prior to market should be packed in a 25 micron PEAKfresh carton liner that is folded closed prior to sealing of the box. This method of packaging provides for a buildup of naturally produced carbon dioxide that is conducive to maintaining good storage conditions.
 
Storage Temperatures
0ºC (32ºF) temperature and 90% to 95% humidity.
