Difference between modified atmosphere storage and controlled atmosphere storage
Answers
Answer:
Explanation:
Controlled or modified atmosphere storage can be used as a complement to proper temperature and relative humidity management (Kitinoja and Kader, 2002). Controlled atmosphere storage refers to a continuously controlled gas atmosphere, while modified atmosphere storage refers to a gas composition that is initially modified. The gas composition within a modified atmosphere storage will change over time due to the respiration rate of food products and the permeability of the packaging (if any) surrounding the food products (Jayas and Jeyamkondan, 2002). The primary benefit of lowering O2 and increasing CO2 surrounding the produce is the effect it has on lowering the respiration/metabolic rate of the commodity, leading to slowing down of the natural senescence process. Other effects of modified O2 and CO2 levels are summarized in Table 2 (Thompson, 1998). From Table 2, careful attention must be taken to maintain a good control on the precise levels of modified gases, since too high levels of CO2 or O2 will likely injure fruits and vegetables. Examples of optimized modified atmosphere conditions are described in Table 3 (Kader, 1994).
Answer:
The atmosphere of Earth is the layer of gases, commonly known as air, retained by Earth's gravity, surrounding the planet Earth and forming its planetary atmosphere
