Difference Between Bananas And Trader Joe's
exposure to oxygen, which reduces ethylene production, resulting in a lower respiration rate. The broccoli packaging at Trader Joe’s could have been used to limit the amount of oxygen from reaching the produce or to allow carbon dioxide to build up in the package, reducing the respiration rate. Generally, lowering the O2 or increasing the CO2 exposure to produce can reduce the respiration rate. The packaging for the broccoli was also used to control the relative humidity surround the produce, resulting in a reduction of water loss. Packaging was not needed at Ralph’s for the broccoli because they were periodically misted with water, which reduces water loss.

In general, the bananas and apples were surrounded by other climacteric fruits, whereas the broccoli was surrounded by non-climacteric fruits/vegetables. Climacteric fruits, such as: apples, avocados, mangos, bananas, etc. produce ethylene after being harvested. Non-climacteric does not produce ethylene after being harvested. The broccoli was located away from the high ethylene producing, climacteric fruits because it is extremely sensitive to ethylene. Ethylene is a ripening hormone that can cause produce to have a shorter shelf life.
The only noticeable stress was found with the bananas at Trader Joes. These bananas had obvious wounds and injuries that were noted by dark brown spots and scars. Injury is the most severe form of stress because large amounts of ethylene are produced when…
